Ordo: Polydesmida
Familia: Paradoxosomatidae
Genus: Eustrongylosoma
Name
Eustrongylosoma pallidum Golovatch & Stoev, 2011 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype♂(NMNHS),Papua New Guinea, West Sepik Province, Telefomin, 1700 m, 19 October 1975, B.S.E. (leg. P. Beron).
Name
To reflect the pallid coloration.
Diagnosis
Distinguished by the pallid coloration, coupled with very poorly developed paraterga and the barbed solenophore tip (see also Key below).
Description
Length ca 20 mm, width of pro- and metazona 1.8 and 1.95 mm, respectively. Coloration uniformly light white-yellowish, with traces of light brown on rear halves of metaterga.
In width, head > collum > segment 3 = 4 < 2 < 5–16. Head densely setose, only vertex with 1+1 setae. Antennae rather short, slightly clavate, reaching beyond segment 2 dorsally; antennomere 6 longer than 2nd. Collum transversely oval, lateral flaps small, regularly and broadly rounded. Tegument generally smooth and shining, only below paraterga faintly microgranulate and rugulose; rear halves of metaterga sometimes faintly rugulose as well. Paraterga of postcollum segments very poorly developed (Fig. 48), full ridges only in segments 2–4, set low (at about 1/2 midbody height), thereafter evident lateral swellings; paraterga 2 with a small, but evident anterolateral indentation, following paraterga completely smooth at lateral margin. Lateral calluses of paraterga at most only very faintly delimited by a sulcus dorsally, more often totally wanting. Ozopores lateral, superficial. Tergal setae nearly fully abraded, a few short ones retained only on collum; setation pattern vague. Axial line wanting. Transverse sulcus on metaterga rather superficial, incomplete, far from reaching bases of paraterga, visible on metaterga 6–17, barely traceable on 5th and 18th. Stricture between pro- and metazona rather faintly striolate. Pleurosternal carinae small, complete in segments 2–4, a rounded caudal denticle retained also in segments 5–7, thereafter entirely missing. Epiproct (Fig. 49) short, flattened dorsoventrally, digitiform; apical papillae large, unciform, directed caudoventrally, tip distinctly emarginate; subapical papillae wanting. Hypoproct (Fig. 50) semi-circular, setigerous paramedian knobs at caudal margin well-separated and small.
Sterna rather sparsely setose; a rather high, linguiform, roundly subtrapeziform, ventral, setose lamina only between coxae 4 (Fig. 51). Legs short, midbody ones ca 0.9–1.0 times as long as body height, apparently somewhat incrassate and longer compared to ♀; ♂tarsal brushes wanting.
Gonopods as in Figs 52–54. Distal quarter of solenophore split into a small lateral lobe (k) and an abundantly denticulate larger branch (j). Femorite with a rather small apicolateral lobe (l).
