'''Diagnosis.''' Species of ''{{Taxon name|Austrarchaea}}'' can be distinguished from all southern Australian species of ''{{Taxon name|Zephyrarchaea}}'' by the significantly taller carapace (CH/CL ratio ≥ 2.0), by the presence of accessory setae on the distal bulge of the male cheliceral paturon, and by the fusion of the two conductor sclerites on the male pedipalp (Rix and Harvey 2012a<ref name="B27">{{aut|Rix M}}, {{aut|Harvey M}} (2012a) Australian Assassins, Part II: a review of the new assassin spider genus ''Zephyrarchaea'' (Araneae, Archaeidae) from southern Australia. ZooKeys 191: 1-62. doi: [http://dx.doi.org/10.3897/zookeys.191.3070 10.3897/zookeys.191.3070]</ref >, fig. 4). Australian {{Taxon name|Archaeidae}} are further distinguished from Old World taxa by the presence of numerous, clustered spermathecae in females (Fig. 7G), and by the presence of a long, wiry embolus on the pedipalp of males (Fig. 4).

Species of ''{{Taxon name|Austrarchaea}}'' can be distinguished from all other extant {{Taxon name|Archaeidae}} (i.e. Malagasy and African species of ''{{Taxon name|Eriauchenius}}'' and ''{{Taxon name|Afrarchaea}}'') by the presence of numerous, clustered spermathecae in females (Figs 5D, 10G, 14G) and by the presence of a long, wiry embolus on the pedipalp of males (Figs 10E, 15E, 27E) (Forster and Platnick 1984<ref name="B5">{{aut|Forster R}}, {{aut|Platnick N}} (1984) A review of the archaeid spiders and their relatives, with notes on the limits of the superfamily Palpimanoidea (Arachnida, Araneae).

The remarkable, elevated shape of the carapace (Figs 4A-C, 10A-B) and the very long chelicerae (Figs 4B, 4D) will also immediately separate this genus from all other Australian spiders.

''Cephalothorax'': Carapace greatly elevated anteriorly (CH/CL ratio usually 2.0–2.4; Fig. 6), with raised, highly modified pars cephalica forming ‘neck’ and bulbous ‘head’ (see Wood 2008<ref name="B38">{{aut|Wood H}} (2008) A revision of the assassin spiders of the ''Eriauchenius'' gracilicollis group, a clade of spiders endemic to Madagascar (Araneae: Archaeidae). Zoological Journal of the Linnean Society 152: 255-296. [http://dx.doi.org/10.1111/j.1096-3642.2007.00359.x doi:10.1111/j.1096-3642.2007.00359.x]</ref >) (Figs 4A-C); ‘neck’ with concomitantly long diastema (see Schütt 2002<ref name="B32">{{aut|Schütt K}} (2002) The limits and phylogeny of the Araneoidea (Arachnida, Araneae). PhD thesis, Humboldt-Universität zu Berlin, Berlin.</ref >) between cheliceral bases and anterior margin of carapace, fused along entire length with sclerotised cuticle (Fig. 4C); cheliceral bases emanating from broad, fully-enclosed cheliceral foramen situated at front of ‘head’ (Figs 4A-B); posterior ‘head’ region usually also bearing two pairs of rudimentary protrusions or ‘horns’, each typically terminating in a short, thickened seta (Fig. 4A). Carapace with densely granulate cuticular microstructure (Fig. 4G), covered in larger setose tubercles arranged in clusters or distinct rows (Figs 4C, 4E); each tubercle bearing single densely plumose or ciliate seta; setose tubercles largest on ‘neck’ and pars thoracica (Figs 4C, 4E). Eight eyes present on anterior margin of ‘head’, in four widely separated diads (Figs 4A-B); AME largest, widely separated, directed antero-laterally on rounded ocular bulge (Fig. 4B); PME situated closely posterior to AME, directed obliquely on postero-lateral side of ocular bulge; lateral eyes contiguous, with shared raised bases, directed ventro-laterally on widest lateral margin of ‘head’ (Figs 4A-B). Sternum longer than wide, covered in setose tubercles; lateral margins separated from dorsal pleural sclerite extending between coxae I-IV. Labium subtriangular, not fused to sternum, directed antero-ventrally at oblique angle to sternum; labrum with pair of divergent projections on anterior surface. Maxillae large (Fig. 4C), straddling labium and labrum, converging distally; serrula a single row of teeth. Chelicerae very long, spear-like, distally divergent (Figs 4B, 4D, 4F), usually with proximal bulging projection (Fig. 4B); both sexes with oval, ectal stridulatory file adjacent to pedipalps (Fig. 4F); males usually also with brush (Figs 4F, 12C, 19C, 22C), short comb (Figs 14C, 18C) or dense tuft (Figs 16C, 17C) of accessory setae on anterior face of paturon. Chelicerae armed with three rows of peg teeth; anterior (prolateral) row with two peg teeth near tip of fang; posterior (retrolateral) row with single peg tooth near tip of fang; median (prolateral) row with more than 15 peg teeth extending along inner prolateral margin of paturon to near base of fang; median row with approximately nine porrect, comb-like peg teeth adjacent to fang, several larger, flattened, spiniform peg teeth near tip of fang, and additional progressively shorter, spiniform peg teeth along inner paturon (Fig. 4D); cheliceral retromargin also with four or five true teeth and prominent cheliceral gland mound.<br />
+
''Legs and female pedipalp'': Legs (longest to shortest) 1–4–2–3, covered with short plumose setae; spines absent; patella I long, greater than one-third length of femur I. Trichobothria present on tibiae and metatarsi of legs; tibiae I-IV each with two trichobothria; metatarsi I-IV each with single trichobothrium; bothrial bases with strongly ridged hood. Tarsi shorter than metatarsi, with capsulate tarsal organ and three claws; tarsi, metatarsi and distal tibiae of legs I-II usually with ventral and pro-ventral rows of moveable, spatulate setae. Female pedipalp with long, porrect trochanter and small tarsal claw; tibia with two dorsal trichobothria.<br />
+
''Abdomen'': Abdomen arched anteriorly, rounded-subtriangular in lateral view, usually with four to six large hump-like tubercles on dorsal surface (Figs 5A, 5E-G); cuticle covered with short plumose setae and numerous sclerotic spots (Figs 5A-B). Epigastric region with sclerotised (setose) book lung covers and dorsal and ventral plates surrounding pedicel (Fig. 5C) (plates fused in males); dorsal pedicel plate with transverse ridges; females with median genital plate and sclerotised lateral sigillae (Figs 5C-D); males with broad dorsal scute fused anteriorly to epigastric sclerites, with or without additional paired sclerites associated with hump-like tubercles (Fig. 5A). Six spinnerets, surrounded by thickened cuticle; ALS largest, PMS smallest; colulus absent. Posterior pair of divided tracheal spiracles situated anterior to spinnerets; males also with transverse row of epiandrous gland spigots situated closely anterior to epigastric furrow.<br />
+
''Genitalia'': Female genitalia haplogyne, with sclerotised, strongly arched genital plate anterior to epigastric furrow (Figs 5C-D); internally with gonopore leading to large, spherical membranous bursa (Fig. 17G; see also Forster and Platnick 1984<ref name="B5">{{aut|Forster R}}, {{aut|Platnick N}} (1984) A review of the archaeid spiders and their relatives, with notes on the limits of the superfamily Palpimanoidea (Arachnida, Araneae). Bulletin of the American Museum of Natural History 178: 1-106.</ref >, fig. 57) overlying two separate, radiating clusters of sclerotised anterior spermathecae (Figs 5D, 10G, 14G, 19G). Male pedipalp with complex, expandable pyriform bulb (Figs 10E, 19E, 23E, 24E), consisting of smooth tegulum, proximal ‘subtegulum’ and associated tegular groove with basal haematodocha (Figs 10E, 23E, 27E) (similar to {{Taxon name|Mecysmaucheniidae}} and potentially analogous to the subtegular division of Entelegynae); distal tegulum with excavate, rimmed cavity surrounding massive, inflatable haematodochal complex incorporating distal embolus, basal embolic sclerite and multiple tegular sclerites (Figs 26D, 27E) (see below); distal haematodochal complex with balloon-like proximal portion (anchored by distal rim of tegulum) and sinuous, tapering embolic portion (anchored by flexible, hinged retro-ventral conductor) (Figs 26D, 27E). Unexpanded pedipalp with folded, wiry embolus abutting conductor (Fig. 17E); tegular sclerites embedded pro-distally (Fig. 20E); pedipalpal expansion and haematodochal inflation (e.g. see Figs 14E, 23E, 26D, 27E) resulting in significant conformational changes to shape of conductor, length and orientation of embolus, and relative position of tegular sclerites.<br />
+
As noted by Wood (2008)<ref name="B38">{{aut|Wood H}} (2008) A revision of the assassin spiders of the ''Eriauchenius'' gracilicollis group, a clade of spiders endemic to Madagascar (Araneae: Archaeidae). Zoological Journal of the Linnean Society 152: 255-296. [http://dx.doi.org/10.1111/j.1096-3642.2007.00359.x doi:10.1111/j.1096-3642.2007.00359.x]</ref >, the homology of the tegular sclerites among archaeid genera remains unclear, and this is especially true for ''{{Taxon name|Austrarchaea}}'' relative to Malagasy and African taxa. For the purposes of this revision, and for an easy comparison among species of ''{{Taxon name|Austrarchaea}}'' from mid-eastern Australia, the moveable tegular sclerites of the pedipalp are here numbered (1–3), relative to their pro-distal position within the unexpanded tegular cavity (e.g. see Figs 11F, 17F). Tegular sclerite 1 (TS 1) is a porrect, variably spiniform (Fig. 25F), rod-like (Fig. 20E) or filiform (Fig. 10F) process (breakable in some specimens; Fig. 21F) that originates near the prolateral base of the conductor, adjacent to the embedded base of the proximal embolic sclerite; during pedipalpal expansion this sclerite usually remains distally directed, positioned adjacent to the embolic haematodocha (Figs 26D, 27E). Tegular sclerite 2 (TS 2) is a distinctive, pointed, usually spur-like process, angled obliquely towards the conductor (Figs 11F, 25F), which is closely associated with the adjacent tegular sclerite 2a (TS 2a); in the unexpanded state, the sinuous, filiform TS 2a is usually obscured and ‘locked’ within a folded groove along the margin of TS 2 (see Forster and Platnick 1984<ref name="B5">{{aut|Forster R}}, {{aut|Platnick N}} (1984) A review of the archaeid spiders and their relatives, with notes on the limits of the superfamily Palpimanoidea (Arachnida, Araneae). Bulletin of the American Museum of Natural History 178: 1-106.</ref >, figs 60, 62). Tegular sclerite 3 (TS 3) is the most disto-dorsally positioned of the tegular sclerites, with a broader, more plate-like morphology relative to TS 1–2, usually visible as a distally pointed or rod-like projection beyond the retro-distal rim of the tegulum (Figs 14E-F, 17E-F, 20D-E).

==Distribution==
 
==Distribution==
Assassin spiders occur in mesic habitats throughout south-eastern, south-western and north-eastern mainland Australia (Fig. 2), usually in montane rainforests (Figs 30C, 38C, 41C) and wet eucalypt forests (Figs 39C, 42C, 45C), but occasionally in temperate heathlands or lowland rainforests (Fig. 40C). In south-eastern Australia they occur on Kangaroo Island (South Australia) and along the Great Dividing Range, from Grampians National Park in south-western Victoria north to Kroombit Tops National Park in south-eastern Queensland. In south-western Western Australia they occur from the Leeuwin-Naturaliste National Park east to Cape Le Grand National Park, with outlying populations in the Porongurup and Stirling Range National Parks. In north-eastern Queensland archaeids occur along the Great Dividing Range, from Eungella National Park near Mackay north to the Mount Finnigan Uplands, near Cooktown. Although this distribution is markedly concordant with the distribution of closed and tall open forests in Australia’s east and extreme south-west (see Specht 1981), assassin spiders appear to be notably absent from Tasmania, from the Australian Alps and from the ‘St Lawrence Gap’ (Webb and Tracey 1981) (Fig. 2), as evidenced by the lack of museum specimens and despite targeted searches by the senior author.

Species of ''{{Taxon name|Austrarchaea}}'' occur in mesic habitats throughout eastern Queensland and New South Wales (Fig. 3), usually in montane rainforests (Figs 1E-F), but also in lowland rainforests or wet eucalypt forests on or adjacent to the Great Dividing Range (Rix and Harvey 2011<ref name="B26">{{aut|Rix M}}, {{aut|Harvey M}} (2011) Australian Assassins, Part I: a review of the assassin spiders (Araneae, Archaeidae) of mid-eastern Australia.

In north-eastern Queensland, archaeids occur throughout the Wet Tropics bioregion, from the Mount Finnigan Uplands (near Cooktown) south to Mount Elliot (near Townsville) (Figs 16–23, 25). In the Mackay and Whitsundays Hinterland region, archaeids can be found in the Eungella National Park (near Mackay), north to Mount Dryander (south of Bowen) (Figs 24–25). The genus is not known to occur south or west of the Australian Alps (Fig. 2), which may be a vicariant biogeographic barrier between populations of ''{{Taxon name|Austrarchaea}}'' and ''{{Taxon name|Zephyrarchaea}}'' (Rix and Harvey 2012a<ref name="B27">{{aut|Rix M}}, {{aut|Harvey M}} (2012a) Australian Assassins, Part II: a review of the new assassin spider genus ''Zephyrarchaea'' (Araneae, Archaeidae) from southern Australia.

==Remarks==
 
==Remarks==
At least three clades of {{Taxon name|Archaeidae}} can be recognised in Australia (Fig. 3B; see also Wood et al. 2010<ref name="B39">{{aut|Wood H}}, {{aut|Griswold C}}, {{aut|Gillespie R}}, {{aut|Elias D}} (2010) Archaeid and mecysmaucheniid spiders and their relatives (Araneae: Archaeidae, Mecysmaucheniidae): phylogeny, biogeography and evolution of the carapace morphology. In: Żabka M (Ed) 18th International Congress of Arachnology, Book of Abstracts, July 2010. Akademia Podlaska, Siedlce, 480.</ref >): a mid-eastern Australian clade, distributed from southern New South Wales to south-eastern Queensland (including the enigmatic, basal species ''{{Taxon name|Austrarchaea monteithi}}'' sp. n.); a north-eastern Queensland clade, endemic to tropical Queensland; and a southern Australian clade, known from Victoria, South Australia and south-western Western Australia. For the purposes of this revision, mid-eastern Australian species are diagnosed relative only to other related species from mid-eastern Australia (i.e. ''{{Taxon name|Austrarchaea nodosa}}'' and its closest relatives; Fig. 3B), all of which possess five or six dorsal hump-like tubercles on the abdomen (Figs 5F-G) and have a carapace height to carapace length (CH/CL) ratio ≥ 2.00. ''{{Taxon name|Austrarchaea daviesae}}'' and related species from north-eastern Queensland have only two pairs of hump-like tubercles on the abdomen (Fig. 5E), and ''{{Taxon name|Austrarchaea hickmani}}'', ''{{Taxon name|Austrarchaea robinsi}}'' and ''{{Taxon name|Austrarchaea mainae}}'' from southern Australia have a carapace height to carapace length (CH/CL) ratio significantly less than 2.00 (M. Rix, pers. obs.).
+
The genus ''{{Taxon name|Austrarchaea}}'' includes three major lineages in eastern Australia (Figs 3–4), each readily distinguished by the morphology of the abdomen and the structure of the male pedipalp (Fig. 4). The most widespread lineage (the ''{{Taxon name|Austrarchaea nodosa}}'' species-group) occurs south of the St Lawrence Gap, from Kroombit Tops National Park in central Queensland, south to the Badja State Forest in southern New South Wales (Fig. 3); species in this lineage possess six dorsal hump-like tubercles on the abdomen and an exposed tegular cavity with a variably scutiform conductor (Fig. 4). The second, most restricted lineage (the ''{{Taxon name|Austrarchaea monteithi}}'' lineage) is known only from the Gibraltar Range National Park in northern New South Wales (Fig. 3); the single known species, ''{{Taxon name|Austrarchaea monteithi}}'', possesses five dorsal hump-like tubercles on the abdomen and an exposed tegular cavity with a hooked conductor (Fig. 4). The third lineage (the ''{{Taxon name|Austrarchaea daviesae}}'' species-group; revised in this paper) occurs north of the St Lawrence Gap, from Eungella National Park north to Cooktown (Figs 3, 25); species in this lineage possess only four dorsal hump-like tubercles on the abdomen (recumbent in ''{{Taxon name|Austrarchaea woodae}}'' sp. n.) and a more enclosed tegular cavity with a very large, arched conductor (Figs 4, 6–15).<br />
 +
Although the derived pedipalpal morphology of ''{{Taxon name|Austrarchaea daviesae}}'' and its relatives is strikingly different to that of congeners further south, the distal tegular sclerites can nonetheless be broadly homologised with those of ''{{Taxon name|Austrarchaea nodosa}}'' and ''{{Taxon name|Austrarchaea monteithi}}'' on the basis of their shape and relative position in the unexpanded tegular cavity. The embolus in all nine known north-eastern Queensland species is a long, sinuous, strongly sclerotized process emerging from the distal bulb pro-ventrally, in some species bearing an additional accessory spur. Tegular sclerite 3 (TS 3) is always a prominent, pro-ventrally directed process, which is fused to the retro-ventral margin of the tegular bulb (the latter of which is usually also concomitantly modified). Tegular sclerite 2 (plus 2a, i.e. TS 2-2a) is usually inserted just behind TS 3 in the unexpanded tegular cavity, forming a distinctive, mesally-looped and distally whip-like structure common to all taxa in the ''{{Taxon name|Austrarchaea daviesae}}'' species-group; the extent of this very long, whip-like TS 2a is usually proximate to the distal extension of the embolus in the unexpanded state. This TS 2-2a morphology is in stark contrast to that of ''{{Taxon name|Austrarchaea monteithi}}'', ''{{Taxon name|Austrarchaea nodosa}}'' and related species, in which TS 2a is usually covered and largely obscured by a more spur-like TS 2 process. Tegular sclerite 1 (TS 1) – generally the most prominent sclerite in species of ''{{Taxon name|Zephyrarchaea}}'' and other species of ''{{Taxon name|Austrarchaea}}'' – is reduced and often obscured in most archaeid species from north-eastern Queensland, although a few taxa possess a larger, more distinctive TS 1 posterior to the TS 2-2a complex (e.g. Fig. 9D). Inter-specific variation among taxa in the ''{{Taxon name|Austrarchaea daviesae}}'' species-group is pronounced, with male pedipalp morphologies usually highly autapomorphic for each species. Five broad pedipalp types (Types A-E) can be distinguished among north-eastern Queensland taxa, with Type A being the most common form, shared between five of the nine known species, and Types B-E each currently unique to single species. Figure 6 highlights differences between these different pedipalp morphologies, which are further diagnosed in the Key to species (see below).

Name

Austrarchaea Forster & Platnick, 1984Wikispecies linkPensoft Profile

  • Austrarchaea Forster & Platnick, 1984: 21; Rix and Harvey 2011[1]: 14.

Type species

Archaea nodosa Forster, 1956, by original designation.
Diagnosis. Species of Austrarchaea can be distinguished from all southern Australian species of Zephyrarchaea by the significantly taller carapace (CH/CL ratio ≥ 2.0), by the presence of accessory setae on the distal bulge of the male cheliceral paturon, and by the fusion of the two conductor sclerites on the male pedipalp (Rix and Harvey 2012a[2], fig. 4). Australian Archaeidae are further distinguished from Old World taxa by the presence of numerous, clustered spermathecae in females (Fig. 7G), and by the presence of a long, wiry embolus on the pedipalp of males (Fig. 4).

Description

For a full generic description see Rix and Harvey (2011)[1]. For notes on genitalia and morphological differences among lineages of Austrarchaea, see Remarks (below).

Distribution

Species of Austrarchaea occur in mesic habitats throughout eastern Queensland and New South Wales (Fig. 3), usually in montane rainforests (Figs 1E-F), but also in lowland rainforests or wet eucalypt forests on or adjacent to the Great Dividing Range (Rix and Harvey 2011[1]). In north-eastern Queensland, archaeids occur throughout the Wet Tropics bioregion, from the Mount Finnigan Uplands (near Cooktown) south to Mount Elliot (near Townsville) (Figs 16–23, 25). In the Mackay and Whitsundays Hinterland region, archaeids can be found in the Eungella National Park (near Mackay), north to Mount Dryander (south of Bowen) (Figs 24–25). The genus is not known to occur south or west of the Australian Alps (Fig. 2), which may be a vicariant biogeographic barrier between populations of Austrarchaea and Zephyrarchaea (Rix and Harvey 2012a[2], 2012b[3]).

Composition

Nineteen described species – Austrarchaea alani Rix & Harvey, 2011, Austrarchaea aleenae Rix & Harvey, 2011, Austrarchaea binfordae Rix & Harvey, 2011, Austrarchaea christopheri Rix & Harvey, 2011, Austrarchaea clyneae Rix & Harvey, 2011, Austrarchaea cunninghami Rix & Harvey, 2011, Austrarchaea daviesae Forster & Platnick, 1984, Austrarchaea dianneae Rix & Harvey, 2011, Austrarchaea harmsi Rix & Harvey, 2011, Austrarchaea helenae Rix & Harvey, 2011, Austrarchaea judyae Rix & Harvey, 2011, Austrarchaea mascordi Rix & Harvey, 2011, Austrarchaea mcguiganae Rix & Harvey, 2011, Austrarchaea milledgei Rix & Harvey, 2011, Austrarchaea monteithi Rix & Harvey, 2011, Austrarchaea nodosa (Forster, 1956), Austrarchaea platnickorum Rix & Harvey, 2011, Austrarchaea raveni Rix & Harvey, 2011, Austrarchaea smithae Rix & Harvey, 2011 – plus the eight new species from north-eastern Queensland: Austrarchaea griswoldi sp. n., Austrarchaea hoskini sp. n., Austrarchaea karenae sp. n., Austrarchaea tealei sp. n., Austrarchaea thompsoni sp. n., Austrarchaea wallacei sp. n., Austrarchaea westi sp. n. and Austrarchaea woodae sp. n.

Remarks

The genus Austrarchaea includes three major lineages in eastern Australia (Figs 3–4), each readily distinguished by the morphology of the abdomen and the structure of the male pedipalp (Fig. 4). The most widespread lineage (the Austrarchaea nodosa species-group) occurs south of the St Lawrence Gap, from Kroombit Tops National Park in central Queensland, south to the Badja State Forest in southern New South Wales (Fig. 3); species in this lineage possess six dorsal hump-like tubercles on the abdomen and an exposed tegular cavity with a variably scutiform conductor (Fig. 4). The second, most restricted lineage (the Austrarchaea monteithi lineage) is known only from the Gibraltar Range National Park in northern New South Wales (Fig. 3); the single known species, Austrarchaea monteithi, possesses five dorsal hump-like tubercles on the abdomen and an exposed tegular cavity with a hooked conductor (Fig. 4). The third lineage (the Austrarchaea daviesae species-group; revised in this paper) occurs north of the St Lawrence Gap, from Eungella National Park north to Cooktown (Figs 3, 25); species in this lineage possess only four dorsal hump-like tubercles on the abdomen (recumbent in Austrarchaea woodae sp. n.) and a more enclosed tegular cavity with a very large, arched conductor (Figs 4, 6–15).
Although the derived pedipalpal morphology of Austrarchaea daviesae and its relatives is strikingly different to that of congeners further south, the distal tegular sclerites can nonetheless be broadly homologised with those of Austrarchaea nodosa and Austrarchaea monteithi on the basis of their shape and relative position in the unexpanded tegular cavity. The embolus in all nine known north-eastern Queensland species is a long, sinuous, strongly sclerotized process emerging from the distal bulb pro-ventrally, in some species bearing an additional accessory spur. Tegular sclerite 3 (TS 3) is always a prominent, pro-ventrally directed process, which is fused to the retro-ventral margin of the tegular bulb (the latter of which is usually also concomitantly modified). Tegular sclerite 2 (plus 2a, i.e. TS 2-2a) is usually inserted just behind TS 3 in the unexpanded tegular cavity, forming a distinctive, mesally-looped and distally whip-like structure common to all taxa in the Austrarchaea daviesae species-group; the extent of this very long, whip-like TS 2a is usually proximate to the distal extension of the embolus in the unexpanded state. This TS 2-2a morphology is in stark contrast to that of Austrarchaea monteithi, Austrarchaea nodosa and related species, in which TS 2a is usually covered and largely obscured by a more spur-like TS 2 process. Tegular sclerite 1 (TS 1) – generally the most prominent sclerite in species of Zephyrarchaea and other species of Austrarchaea – is reduced and often obscured in most archaeid species from north-eastern Queensland, although a few taxa possess a larger, more distinctive TS 1 posterior to the TS 2-2a complex (e.g. Fig. 9D). Inter-specific variation among taxa in the Austrarchaea daviesae species-group is pronounced, with male pedipalp morphologies usually highly autapomorphic for each species. Five broad pedipalp types (Types A-E) can be distinguished among north-eastern Queensland taxa, with Type A being the most common form, shared between five of the nine known species, and Types B-E each currently unique to single species. Figure 6 highlights differences between these different pedipalp morphologies, which are further diagnosed in the Key to species (see below).
