Figs 1A-E View Figure 1 , 2A-G View Figure 2 , 3A-G View Figure 3 , 4A-C View Figure 4

Diagnosis.

Recognized by overall coloration brownish; forewing with fuscous markings developed irregularly, contrasted with background (Fig. 1A, B View Figure 1 ). Metope without markings, lower half concolorous (Fig. 2C View Figure 2 ). Phallic complex having two pairs of ventral aedeagal hooks, third pair not developed; upper pair developed horizontally and lower diverging to middle, attached to aedeagus (Figs 2E-G View Figure 2 , 4A-C View Figure 4 ). Anal tube convex apically (Fig. 2B View Figure 2 ).

Description.

Male. Coloration. General coloration of body brown; Coryphe concolorous with background, median carinae lighter than background; Pronotum yellowish-brown, half to posterior margins darker than background distinctly; mesonotum yellowish-brown, with fuscous markings between median and lateral carinae (Fig. 1A, B View Figure 1 ); Metope concolorous with background, all margins with yellowish spots irregularly, lateral margins with fuscous and contrast with background; rostrum darker than background. Gena concolorous with background (Fig. 1C View Figure 1 ). Forewing of veins darker than background, with fuscous markings developed irregularly (Fig. 1A, B View Figure 1 ). Legs darker with background generally, joints lighter than background (Fig. 1B View Figure 1 ). Female. Same as male in general features, body relatively larger than male.

Surface and vestiture. Body without wax layer, rough.

Head. Head with compound eyes roundly ovate, larger than pronotum distinctly; Coryphe at base concaved, length shorter than width at midline, apex angulated and slightly protruded after compound eyes, median carinae well-developed (Fig. 1A View Figure 1 ). Metope ovate, lateral keels protruded and rounded in ventral view, widest at middle, median carina present, margins with postclypeus concaved. Postclypeus and anteclypeus with weak median carina, lateral carinae absent. Antennae short, clavated. Compound eyes semicircular; ocelli absent (Fig. 1C View Figure 1 ).

Thorax. Pronotum triangular, length longer than width; anterior margins longest at middle, posterior margin slightly concave at midline; median and lateral carinae developed weakly. Mesonotum triangular, length shorter than width, posterior margins pointed; median and lateral carina visually developed (Fig. 1A View Figure 1 ). Forewing irregularly ovate. Pcu and CuP reaching apical margins, CuA dividing at almost hind margins, Mp and Rp dividing at almost 1/3 (Fig. 1D View Figure 1 ); Hindwing as long as forewing, trilobed (Fig. 1E View Figure 1 ).

Male genitalia. Pygofer in lateral view slightly wide basally, margins irregularly (Fig. 2C View Figure 2 ); Phallic complex long and symmetrical, complex endosome arising widely at apex (Figs 2E, G View Figure 2 , 4A, C View Figure 4 ). Two pairs of ventral aedeagal hooks developed at ventral; the upper pair strongly curved to upward and surpassing aedeagus; the lower curved and not surpassing aedeagus (Figs 2F View Figure 2 , 4B View Figure 4 ); genital style roundly widest at basal, pointed at apical; anterior margins simply protruded at middle, blunt; capitulum of style spinous, curved to ventrally (Fig. 2D View Figure 2 ); Anal tube in dorsal view, ovate and convex apically; anus placed at middle, anal column small, not reaching the posterior margin (Fig. 2B View Figure 2 ).

Female genitalia. Gonapophysis VIII partly flattened; dorsal margins almost straight, with sharp apex and well visible teeth at posterodorsal margin (Fig. 3E View Figure 3 ). Gonapophysis IX in lateral view, slightly curved to dorsally, apical pointed (Fig. 3F View Figure 3 ); in dorsal view, with two pointed bumps at apical, posterior connective lamina sclerotized (Fig. 3G View Figure 3 ). Sternum VII with lateral lobes developed, median portion narrow; anterior margins almost straight; posterior margins with two triangular bumps, median portion deeply concaved (Fig. 3H View Figure 3 ). Anal tube elongated, with numerous setae developed; anus placed basal, anal column short and not surpassing the median portion (Fig. 3B View Figure 3 ). Gonoplac oval, widest at middle (Fig. 3D View Figure 3 ).

Male (N = 2)/Female (N = 2). Body length (including forewing): 4.91-4.94/5.53-5.55; body width (including forewing): 2.51-2.53/2.72-2.75.
