Taxonavigation

Genus: Nixonia

Name

Nixonia masneri van Noort, S., 2009Wikispecies linkPensoft Profile

Distribution

Distribution and habitat association. Currently only known from two widely spaced localities: Kogelberg Nature Reserve in the Western Cape Province and Avontuur Farm in the Northern Cape Province (Fig 3). The species is associated with the Fynbos biome and is thus likely to be present over a much larger area than currently recorded (the extent of the Fynbos biome is depicted in Fig 3). Distribution map available at http://hol.osu.edu/index.html?id=247388.

Diagnosis

Diagnosis. Most similar to Nixonia lamorali, distinguished by the mesoscutum which is as wide as long; a more expanded scape (2.5x longer than wide); lack of setae on the vertex; occipital carina present dorsally; and pronotal shoulders that are subquadrate.

Description

urn:lsid:zoobank.org:act:5l495B19-AA60-4560-AAC6-2EED4l10C0ED

Figures 1A -F

Description: Holotype male. Length: 8.5 mm; completely black, mandibles usually black, but may be reddish-brown (figs 1A, B); wings infuscate throughout, brownish.

Head (figs. 1C-E) transverse in dorsal view, width 1.5x length; vertex rugulose-punctate, shining; OOL short, lateral ocellus separated from inner orbit by a third of ocellar diameter; POL 1.6x LOL; occiput rugulose-punctate, with reticulate microsculpture; occipital carina weakly developed dorsally; frons rugulose-punctate, shining, above toruli with few transverse wrinkles medially; frons somewhat narrow, IOS 0.9x greatest length of eye; toruli closely approximated, separated by distance less than half torulus diameter, frons between toruli not projecting, flat; rim of torulus evenly raised; apical margin of clypeus with blunt medial projection; position of malar sulcus demarcated by fine granulate microsculpture; sculpture of cheeks laterad of malar area rugose-punctate, with distinct longitudinal sculpture; mandible short, bidentate, upper tooth only slightly longer than lower, without dense basal tuft of setae; maxillary palpal segment 4 distinctly expanded medially, subtriangular; A1 finely reticulate, 2.5x longer than wide, greatest width beyond apical 0.6 of segment; length of A3 1.5x length of A2.

Mesosoma (figs. 1 C,D) as high as wide, length 1.4x height in lateral view; pronotal shoulders coarsely punctate; lateral surface of pronotum coarsely punctate; netrion punctuate-rugulose with weak longitudinal striation; mesoscutum deeply punctate, with broad interstices; parapsidal lines absent; scutellum coarsely punctate, with fine microsculpture on posterior margin; median propodeal tooth subcordate, sides straight, length 1.4x maximum width, pointed apically, with median excavation bounded by lateral longitudinal carina; upper mesepisternum with strong longitudinal sculpture; fine foveae separating mesepisternum and mesepimeron extending from base of wing to coxal cavity; lower mesepisternum finely reticulate-punctate; mesepimeral hook smooth; tegula finely punctate; apex of forewing extending to apex of T4; fore and mid tibiae with fine, semidecumbent spines on outer surface.

Metasoma (figs. 1A,B,F) 3.7x longer than greatest width; Tl 1.4x wider than long; T1-T4 longitudinally rugose.

Etymology

Etymology. Named in honour of Lubomir Masner, who with his enthusiasm and dedication to the discovery and description of parasitic wasp species, has inspired passion in numerous proteges to catalogue the incredible hyper-diversity of the micro world.
