Type species: Takagioma unita Thapa, 1989

Type locality: Nepal

Description: Yellowish to ochraceous. Dorsum with white band bordered with thin brown line extended from crown apex laterad along pronotal margin and continuing onto forewing sublaterally to stem of 3rd apical cell ( Figs 1, 5, 9, 13, 17, 21 ); forewing with brownish smoky patches on apical cells. Body depressed and small. Head as wide as or wider than pronotum, vertex with anterior margin conically produced, middle length nearly equal to width between eyes. Face flattened and yellow on apex, frontoclypeal area concave, anteclypeus long ( Figs 4, 8, 12, 16, 20, 24 ). Pronotum with posterior margin slightly concave, middle length longer than crown. Scutoscutellar sulcus distinct ( Figs 3, 7, 11, 15, 19, 23 ). Forewing with 1st apical cell accounting for about 1/2 of distal portion, 2nd to 4th apical cells small and 3rd petiolate. Hind wing colorless and transparent, with ambient vein connecting with costa vein, CuA branched in most members of genus (Figs 41,42).

Abdominal apodemes underdeveloped and extending to 3rd or 4th of abdominal sternite ( Figs 28 , 36 , 43 , 56 , 59 , 71 ). Male pygofer well sclerotized, pygofer side elongated caudoventrally with a large and gradually narrowed hook arising on inner side ( Figs 26 , 32 , 44 , 50 , 57 , 67 ), and with numerous fine setae on dorsal margin ( Figs 45 , 51 , 62 , 68 ). Subgenital plate broad basally and extended beyond pygofer side with a row of macrosetae laterally and some rigid microsetae apically ( Figs 27 , 35 , 46 , 52 , 63 , 69 ). Paramere long with slim caudal part and broad central part ( Figs 31 , 39 , 49 , 54 , 64 , 73 ). Connective short and fused with aedeagus, lateral feet developed. Aedeagus stout or slim, shaft simple and tapered distally or with lateral processes terminally, dorsoatrium developed or underdeveloped. Gonopore subterminal ( Figs 29 , 37 , 47 , 55 , 64 , 73 ).
