Trifida Thapa et Sohi, 1986:57

Type species: Trifida quadripunctata Thapa et Sohi, 1986

Head a little narrower than pronotum with length along midline slightly greater than distance between eyes, but 3/5 time to middle length of pronotum ( Figs 9–12 ). Forewing with brown spot at apex of cu cell ( Figs 3, 4 , 33 ). Hind wing with CuA” separate from MP"+CuA' distally, anal veins fused and av extended to c ( Fig.34 ).

Abdominal apodemes reaching 4th or 5th abdominal sternite. Pygofer with dorsal V-shaped sclerotization articulating with variform process on side ( Figs 22–23 , 26 , 31 , 38 ). Subgenital plate longer than pygofer, nearly triangular, broad basically and narrowed apically with lateral tooth-like protrusion at about apical 1/3 and several microsetae along outer and apical margins ( Figs 20 , 27 , 32 , 39 ). Paramere long with subapical protrusion simple ( Figs 19 , 25 , 30 , 37 ). Connective short, caudal end fused with aedeagus, anterior arms widely separated. Aedeagal shaft bipartite with symmetrical appendages; dorsal apodeme and process developed, process with apical part narrowed and termination bicornate and hooked; gonopore subapical ( Figs 17–18 , 24–25 , 28–29 , 35–36 ).

Distribution. Oriental Region.
