Stenopsoides punctatus Semeraro View in CoL sp. nov.

( Figs 1B,F,J View FIGURE 1 , 4A–E View FIGURE 4 , 6 View FIGURE 6 )

Description. Body length 5.2–5.9 mm (n=8). General colour yellow, unicolorous. Face yellow with coarse brown pitting all over. Pronotal tubular extension yellow with brown coarse pitting, dark brown/ black at apex; calli smooth yellow (distinct), mesonotum smooth, yellow. Tegmen mostly transparent with hint of yellow, veins pale yellow or colourless; with black/ brown fine dots evenly scattered over tegmen. Legs entirely yellow.

Head. ( Figs 1B,F View FIGURE 1 , 4A,C,D View FIGURE 4 ) Distance between coronal pits equal to inter-ocellar distance; ocellus slightly closer to eye compared to midline of face, inter-ocellar distance between 2.3–2.9 times ocellar-ocular distance; frontoclypeus width equal to or slightly wider than its length, width 0.7–0.8 times width of face between eyes (n=7); lorum wider than long; maxillary plate narrowly visible posterior to lorum; anteclypeus strongly curved mesad, slight constriction preapically, expanded at apex.

Thorax. ( Figs 1B,J View FIGURE 1 , 4A,B,C View FIGURE 4 ) Pronotal tubular extension conical and directed dorsoanteriad; coarsely pitted, rugose, striae not distinctly visible; indistinct medial ridge apically. Mesonotum + scutellum with fine dark brown or concolourous pitting; width across base of mesonotum equal to length or slightly narrower. Tegmen length 3.5 times its width. Legs metafemur with apical setal formula 2+1+0 or 2+2+0; metatibia with 7–8 macrosetae on anterodorsal margin (n=4); 4–5 fine setae on anterior face of metatibia (n=4).

Abdomen. ( Fig. 4E View FIGURE 4 ) Female seventh sternite (7S) shape as in generic description. Width around 2.6–2.9 times maximum height. Ovipositor apex slightly protruding beyond apex of pygofer in ventral view.

Etymology. The species epithet “ punctatus ” is a Latin adjective meaning dotted. It refers to the distinct brown/ black dots evenly distributed over the tegmen of this species.

Type material. HOLOTYPE ♀, AUSTRALIA: Northern Territory, Stuart Highway , 296 km S of Tennant Creek, 29 Nov 1972, D. H. Colless, at light, ( ANIC, LS No. 00127) . PARATYPES, 5♀, collection details as per holotype ( LS No. 00125–126, 128–129, ANIC; WAM Reg no. 28367) ; 1 ♀, AUSTRALIA: Western Australia, Karijini Na- tional Park , 2 km N by W of Ranger Station, 18 April 2003, T. Weir, at light open forest, 22°20’24”S 118°16’12”E ( ANIC) GoogleMaps ; 1♀, AUSTRALIA, Western Australia, Marandoo Camp , 22 deg 38’ S, 118 deg 06’ E, 5–19 May 1980, T.F Houston 317-1 ( WAM Reg no. 28367) .

For the specimens from Stuart Highway the following coordinates: 22°23’30”S 133°22’02”E were extrapolated from the data on the label and used in the distribution map.

Distribution. Northern Territory and Western Australia ( Fig. 6 View FIGURE 6 ).

Host. Unknown.

Differential diagnosis. Stenopsoides punctatus may be distinguished from other species in the genus by its smaller body size, having no stripes on the pronotal extension which is yellow with brown coarse pitting ( S. turneri and S. newi have brown stripes on the pronotum and S. truncatus has a black mark at the apex), having tegmen with evenly distributed fine black dots ( S. turneri has dots restricted to the costal cells and the other two Stenopsoides species have no dots on the tegmen). In common with S. turneri , S. punctatus has ocelli slightly closer to the eyes than to the midline of face (while S. newi Semeraro sp. nov. and S. truncatus Semeraro sp. nov. have ocelli about equidistant from eyes as to midline of the face). It has been collected at light in the open forest.
