Stuckenbergomyia secunda : Smith, 1980: 436 (catalogue).
Diagnosis.
This species is characterised by the faint brown vittae beneath acrostichals and dorsocentrals; broad wings and 4 pairs of long scutellar setae; male terminalia: symmetrical, held at apex of abdomen, surstyli broadly articulated lobes.
Redescription.
Head: Holoptic with enlarged facets on upper two-thirds. Antenna dark brown; postpedicel length ca. 4 × basal width; stylus cylindrical, about as long as basal width of postpedicel; apical mechanoreceptor one-third length of stylus.
Thorax: Mostly dark greyish pruinescence. Scutum with brownish vittae below acrostichals and dorsocentral rows (viewed anteriorly); anterior margin of postpronotal lobe shiny, lacking pruinescence. Acrostichals 4-serial anteriorly, biserial anterior to prescutellar depression; dorsocentral setae biserial and short anteriorly, longer, darker and uniserial at prescutellar depression; postpronotal setae numerous, long and pale; numerous pale presutural and postsutural supra-alar setae; 4 pale notopleural setae; 1 pale postalar seta; 4 pairs of pale scutellar setae, longer than length of scutellum. Proepisternum with several long, pale setae.
Legs: Mostly brown, with apex of femora and base of tibiae yellowish (Fig. 10).
Wing (2.7-3 mm) (Fig. 11): Broad, anal lobe nearly right-angled; alula well-developed. Costal margin at humeral crossvein expanded, costal cell broad; costa strongly reduced beyond R4+5; spur vein arising from cell cua. Halter knob pale.
Abdomen: Slightly paler than thorax; setae pale; sternites paler than tergites; tergite 8 narrow medially, expanded laterally, bearing pair of setae.
Male terminalia (Figs 13, 14): Symmetrical, held at apex of abdomen, directed dorsally, not arched over abdomen; rotated 45° to right. Cercus quadrate, thinly sclerotised, weakly pigmented, clothed in slender setae; hypoproct broad with fine setae on posterior margin, arched medially. Epandrial lamellae very narrowly joined; surstylus broadly articulated with sickle-shaped, arched posterior process. Hypandrium with pair of setae; postgonite consisting of 2 pairs of sickle-shaped, slender, processes; ventral apodeme broad, plate-like. Phallus and ejaculatory apodeme not examined.
