Toxotrypana picciola Blanchard

Morphology

Body. Setae red brown, or dark red brown.

Head. Frons with brown band or mark including ocellar tubercle and extending to eye margin (also often dark brown anteriorly). Occiput with 3 separate or 1 large trilobed brown area on medial and lateral sclerites. Frontal setae 0–3 (small, weak). Orbital setae small, weak, or absent. Ocellar seta weak, small or absent. Gena with brown spot below eye (or sometimes mostly brown). Facial carina in profile concave or flat on dorsal 2/3, or produced near midheight (occasionally slightly produced). Face with ventral part gradually tapered laterally; mostly to entirely brown. Face without whitish markings. Antenna not extended to ventral margin of face. Arista of male without preapical expansion. Palpus in lateral view evenly setulose.

Thorax. Postpronotal lobe and notopleuron entirely microtrichose. Scutum nonmicrotrichose except narrowly medially and laterally and broad triangular postsutural area, or nonmicrotrichose (except on lateral margin, along transverse suture, and posterior to suture, on and lateral to sublateral yellow vitta). Scutellum disc microtrichose basally (apical margin nonmicrotrichose). Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae absent or small and weak, much shorter than scutellum length. Acrostichal seta small, weak (often), or absent. Basal scutellar seta absent. Katepisternal seta absent. Scutum pale sublateral postsutural vitta extended posteriorly to intra-alar seta (usually), or not extended posteriorly to intra-alar seta (sublateral and lateral brown vittae sometimes narrowly connected on posterior margin). Scutum posteriorly with brown or orange brown band or other transverse marking or larger posteromedial mark. Scutum with 2–3 pairs of brown vittae. Submedial scutal vittae connected to posteromedial brown mark. Scutellum with brown band on sides and apex. Mesopleuron mostly dark orange to brown, or mostly yellow to orange, with dark brown spots or bands on at least anepisternum, katepisternum and anepimeron. Anatergite with complete brown sublateral vitta, or mostly or entirely brown. Subscutellum entirely brown to dark brown (usually), or yellow to red brown medially, dark brown laterally. Mediotergite entirely brown to dark brown (usually), or yellow to red brown medially, dark brown laterally, or orange with 3 dark brown vittae. Femora at least one femur partly to entirely brown. Fore femur with posterodorsal and ventral rows of setae weak, barely differentiated from setulae.

Wings. Wing pattern with basal half of S-band reduced to streak in cubital cells, costal band continuous to wing apex, proximal arm of V-band variable. Cell bm entirely hyaline or infuscated only along subapical fold. Subapical hyaline area in radial cells distal to r-m S-band entirely covering cell r2+3 distal to r-m. S-band distal section without marginal hyaline band or spots in cell r2+3 or near apices of R2+3 or R4+5. V-band proximal arm absent or diffuse and much paler than apical half of S-band. V-band distal arm absent. S-band distal section width ratio (width of S-band/width of cell r2+3, both measured perpendicular to costal margin at apex of vein R2+3) 1. Costa in male with 2–3 rows of setulae on anterior margin between crossvein h and apex of vein R1 much stouter than setulae on dorsal and ventral sides and more distally.

Abdomen. Abdomen petiolate, syntergite 1+2 with basal part narrow and parallel-sided and apical part distinctly broader. Abdominal tergite with brown markings. Oviscape strongly dorsally arched. Eversible membrane with dorsobasal denticles all sclerotized, in continuous triangular to semicircular or suboval pattern. Aculeus tip lateral margins not curved dorsally; not flared outward at or proximal to base.
