Type species.

Eudeferunda lenita Chen, Yang & Wilson, 1989, by original designation.

Diagnosis.

Small size. Head with eyes narrower than pronotum (0.7-0.8:1) (Figs 7, 19). Vertex produced before eyes about 0.4 times of its length, longer in middle line than wide at base (1.4:1), disk distinctly depressed, median carina basal half prominent, anterior half obsolete, anterior margin acutely rounded convex, lateral margins carinate, straight, diverging posteriorly, posterior margin in middle angulately convex (Figs 7, 19). Frons longer in middle line than widest part (1.25-1.4:1), basal margin subtruncate or truncate, about quarter length of widest part, lateral margins strongly foliate basally, slightly convex laterally, thence incurved into suture (Figs 8, 20). Postclypeus shorter than frons in middle line (0.4-0.6:1) (Figs 8, 20). Eyes incised beneath, not or slightly overlapping pronotum (Figs 7, 9, 19, 21). Ocelli detached from eyes. Antennae with pedicel subglobose. Pronotum moderately short, as long behind eyes as in middle line, disc with median carina shorter than lateral carinae (0.5:1) (Figs 7, 19). Mesonotum tricarinate, longer than vertex and pronotum together, lateral carinae slightly diverging posteriorly, middle carina apically obsolete (Figs 7, 19). Forewing 2.5-2.9 times as long as broad, CuA1 not convex strongly, Sc+R forking level of CuA1 fork, both slightly distally union of PCu with A1, clavus terminating at midway of forewing (Figs 10, 22). Post-tibia with a single lateral spine at basal 2/5, metatibio-tarsal formula of hind leg 8 –7– 6 (Figs 5-6). Anal segment relatively short, in dorsal view apical margin concave in middle (Figs 12, 23). Pygofer in lateral view distinctly longer ventrally than dorsally, anterior margin concave, posterior margin convex and produced a curved process directing downward (Figs 13, 24); in ventral view medioventral processes paired, median cleft deep (Figs 14, 25). Dorsal margin of gonostyle with a large triangular process laterad, thence laterad convex near base (Figs 15-16, 26). Male genitalia with phallobase submembraneous, tube-like, phallobase with dorsal and ventral lobes; ventral lobe of phallobase in ventral view cleft at apical margin in middle, each lateral side with a pointed processes, bilateral areas with thorns; in dorsal view, dorsal lobe of phallobase with apical margin broadly incised in middle; phallic appendages longer than phallobase about 3:1, gradually narrowing apically (Figs 17-18, 27-28).
