3.1.12 Tetraophthalmus janthinipennis cyanopterus (Gahan, 1900) ( Figs 2F , 3F , 4K–L )

Tegmen about 4.0 times as long as wide, curved; lateral lobes long, about 1/4 times as long as tegmen, narrowed toward apex, about 2.1–2.6 times as long as wide; with long hairs at apical 1/2 and dense setae at base; roof very short, about 0.3–0.4 times as long as lateral lobes; apex protruding and dehiscent at middle; apical margin somewhat flat; ringed part converging at apex, apex slightly fishtail. Median lobe plus median struts strong curved, about 4.3-4.6 times as long as wide; median lobes 2.1 times as long as median struts; dorsal plate slightly shorter than ventral plate, apex slightly pointed. Internal sac with rod at apex, rod thick and about 1/3 times as long as median lobe plus median struts. 8th abdominal tergaum sub-square, 0.9 times as long as wide; apex flat, with dense setae; 8th abdominal sternum slightly shorter and narrower than tergaum, apex flat, with setae on lateral sides; spiculum gastrale long, about 1.6 times as long as tergaum.
