Diagnosis
Small (2.25–2.40 mm (n = 3)), slender, dark and hirsute species. Wing dimorphic: male stenopterous; bilobed distal apex, with very long digitation on distal margin (Fig. 20E). Stalk-like process dark brown on basal half, pale on distal half; lobed apex mostly black, digitation hyaline with black distal ½ margin. Female micropterous, wing bilobate, squamiform, apical margin of each lobe bearing setae – the posterior lobe has 2 long setae and the anterior one 2 short setae (Fig. 20F). Wing veins not distinguishable in either sex. Occiput largely covered by grey microtrichia; 1 pair of long lateroclinate ocellars; 1 pair of proclinate verticals; palpi, proboscis and antennae black; postpedicel lanceolate, 2.5 times as long as pedicel; stylus 2 times as long as scape, pedicel and postpedicel combined. Thorax black with episternum densely covered with grey microtrichia, appearing sub-triangular in lateral view. Postpronotal lobe bearing 7 setae laterally, ca 9 acrostichal setae, irregular biseriate, of equal length; notopleuron with 1 strong, prominent seta plus 5 small setae; 2 strong prescutellar setae present laterally; scutellum with 2 similar setae medially. Legs mainly dark with pattern of yellow and brown to black; male fore tibia with dense ciliation of long hair-like setae; male mid with anteroventral apical spur produced into a barely noticeable apical elongation, about as long as diameter of tibia at apex (Fig. 19A); spur has several distinct setae and, on the distal half margin, 4 short, stout, curved, spinose setae. Abdomen black, tergites and sternites overall uniformly covered by grey microtrichia and long setae; apical sternites with longer setae. Terminalia (Fig. 9) subglobular, mostly covered with grey microtrichia, dark brown. Right surstylus produced into short projection, bearing long setae at the lateral margins and ca 11 denticles. Right cerci slightly longer than left, both enclosed in epandrial lamellae. Left epandrial lamella bilobed.
