Diagnostic characters.
Body small, slightly flat in vertical view. Width of head ( Figs 1 View Figures 1–8 , 3 View Figures 1–8 , 5 View Figures 1–8 , 7 View Figures 1–8 ) including eyes narrower than pronotum. Vertex ( Figs 13 View Figures 13–22 , 32 View Figures 32–41 , 51 View Figures 51–60 ) with width at base longer than length in middle ca. three times, disc of vertex depressed distinct, without median carina, anterior margin slightly convex or nearly straight, posterior margin obviously arched concave. Gena ( Figs 14 View Figures 13–22 , 33 View Figures 32–41 , 52 View Figures 51–60 ) with one obvious ocellus between compound eye and antenna in lateral view. Frons ( Figs 15 View Figures 13–22 , 34 View Figures 32–41 , 53 View Figures 51–60 ) rectangular, with median carina explicit, without lateral carina, the apical margin straight or not obviously forked, nearly reaching to frontoclypeal suture, with weeny tubercles near lateral margin, lateral margin nearly paralleled, the base slightly narrow, broader toward to apical margin, the widest below level of compound eyes. Clypeus ( Figs 15 View Figures 13–22 , 34 View Figures 32–41 , 53 View Figures 51–60 ) triangular, with median carina distinct or obscure. Rostrum surpassing mesotrochanters. Pronotum ( Figs 13 View Figures 13–22 , 32 View Figures 32–41 , 51 View Figures 51–60 ) without median carina or degraded, with lateral carina, without sub-lateral carina, pit each other between median carina and lateral carina, apical margin obtuse-angle concaved, posterior margin straight. Mesonotum ( Figs 13 View Figures 13–22 , 32 View Figures 32–41 , 51 View Figures 51–60 ) triangular, with median carina obvious or obscure or not, without sub-lateral carina. Forewings ( Figs 9 View Figures 9–12 , 16 View Figures 13–22 , 35 View Figures 32–41 , 54 View Figures 51–60 ) ovate, with length ca. 1.8 times longer than maximum width, anterior margin slightly cambered, anterior margin and posterior margin subparallel, apical margin obtusely rounded, longitudinal veins obvious and elevate, short transverse veins pale, with wide "hypocostal plate", ScP and RP convergent near base, ScP vein long, no forked, nearly reaching the apical margin forewing, MP bifurcating two branches in basal 1/3, CuA forked into two branches near middle, behind the joint of Pcu and A1; CuP present, Pcu and A1 uniting in middle of clavus. Hindwings ( Figs 17 View Figures 13–22 , 55 View Figures 51–60 ) absent or reduced, small, vein simple. Hind tibiae each with two lateral spines, spinal formula of hind leg (7-9) –(8-9)– 2.
Male genitalia.
Anal tube ( Figs 11 View Figures 9–12 , 19 View Figures 13–22 , 37 View Figures 32–41 , 57 View Figures 51–60 ) moderately long, irregularly pentagonal in dorsal view, the basal part narrow, the apical part more broad, maximum width in apical 1/3 of anal tube. Anal style ( Figs 11 View Figures 9–12 , 19 View Figures 13–22 , 37 View Figures 32–41 , 57 View Figures 51–60 ) moderately long, not surpassing anal tube. Pygofer ( Figs 10 View Figures 9–12 , 18 View Figures 13–22 , 36 View Figures 32–41 , 56 View Figures 51–60 ) symmetrical, irregularly rectangular; anterior margin and posterior margin nearly paralleled in lateral view, dorsal margin and ventral margin nearly paralleled in lateral view. Genital styles ( Figs 10 View Figures 9–12 , 18 View Figures 13–22 , 38 View Figures 32–41 , 56 View Figures 51–60 ) relatively rectangular, dorsal margin and ventral margin slightly arched, without triangular prominence near dorsal margin before capitulum. Capitulum of genital styles irregularly triangular, the basal part with half-elliptical process, the apical part with thin triangular process, neck obvious. Phallobase ( Figs 12 View Figures 9–12 , 21 View Figures 13–22 , 40 View Figures 32–41 , 59 View Figures 51–60 ) symmetrical, “U” -shaped tube in lateral view, dorsal lobe with apical part membranous, splitting into one sclerous branch in apical 1/3, with lateral lobe splitting into two branches, with ventral lobe shorter than dorsal lobe. Aedeagus ( Figs 12 View Figures 9–12 , 21 View Figures 13–22 , 40 View Figures 32–41 , 59 View Figures 51–60 ) with various long processes in lateral view.
Female genitalia
( Figs 23-25 View Figures 23–31 , 42-44 View Figures 42–50 , 61-63 View Figures 61–69 ). Anal tube ( Figs 26 View Figures 23–31 , 45 View Figures 42–50 , 64 View Figures 61–69 ) ovate, long in middle than the width, apical margin with unobvious or obvious membranous triangular protuberance. Anal style ( Figs 26 View Figures 23–31 , 45 View Figures 42–50 , 64 View Figures 61–69 ) long, located near base of anal tube. Hind margin of gonocoxa VIII with endogonocoxal lobe not obvious ( Figs 27 View Figures 23–31 , 46 View Figures 42–50 , 65 View Figures 61–69 ), endogonocoxal process membranous, narrowing gradually. Anterior connective lamina of gonapophysis VIII irregularly rectangular, with sclerous triangular process in basal dorsal margin, with two or three lateral teeth bearing two or three keels in lateral group and three teeth in apical group ( Figs 27 View Figures 23–31 , 46 View Figures 42–50 , 65 View Figures 61–69 ). Posterior connective lamina of gonapophysis IX ( Figs 28 View Figures 23–31 , 29 View Figures 23–31 , 47 View Figures 42–50 , 48 View Figures 42–50 , 66 View Figures 61–69 , 67 View Figures 61–69 ) triangular, with lateral field and sublateral field without obvious process ( Figs 28 View Figures 23–31 , 47 View Figures 42–50 , 66 View Figures 61–69 ); median field with prominence (median dorsal process) ( Figs 28 View Figures 23–31 , 47 View Figures 42–50 , 66 View Figures 61–69 ); ventroposterior lobes bent angle obtuse or acute (posterior ventral lobes) ( Figs 29 View Figures 23–31 , 48 View Figures 42–50 , 67 View Figures 61–69 ).
