Description.

Size. Male 3.7-4.1 mm.

General color of body brownish yellow. Vertex yellow, with large creamy patches surrounding ocelli caudomesad, coronal suture brown. Eye black. Face with a longitudinal orange stripe in middle which is less distinct at apex of anteclypeus, rest area of face yellow except genae whitish. Antennae with scape yellow, pedicel brownish. Pronotum brownish yellow centrally and whitish posteriorly, surrounded by irregular arc of light hypodermal pattern in addition to three irregular creamy patches along ante rior margin. Centre of scutellum with a quadrate whitish patch anteriorly, a triangular creamy patch caudad of scutoscutellar sulcus and two triangular beige patches at basal angles on each side. Forewing and hindwing subhyaline. Dorsum of abdomen blackish, ventrally sordid yellow. Legs yellow except 1st and 2nd tibia and tarsus brown.

Basal sternal abdominal apodemes parallel sided, not reaching end of segment 3 (Fig. 8). Male pygofer in lateral view with rounded apex, bearing 7-9 rigid setae along posterior margin (Figs 5, 11); dorsum of pygofer deeply emarginated caudo-medially, dorsal bridge nearly quarter of the total length of pygofer, horns broad, widely separate basally and diverging slightly (Fig. 6). Subgenital plate in lateral aspect with apical 2/5 curved dorsad, A-group setae (4) longer and slightly thicker than B-group, B-group setae (19-20) occupying almost 2/3 length of anterior margin, relatively evenly distributed to apex of plate, C-group setae (14-15) starting at 1/4 distance from base and extending to apex of plate, D-group setae (22-25) roughly biseriate, starting basodorsad of subgenital plate (Figs 5, 7, 11, 13, 14). Paramere narrowed in apical half, dentifer bearing 9-10 prominent teeth and about 4 long setae and few sensory pits on lateral surface near apex (Fig. 18). Preatrium of aedeagus fairly long in lateral aspect, arched subbasally and subapically, subapical protrusion of aedeagus tapering and afterwards strongly bent ventrad, terminal part of aedeagus needle-shaped, slightly sinuate, gonopore subterminal, ventral, almost at the same level the aedeagus with a small process on the dorsal side (Figs 5, 7, 11, 15, 16). Connective quadrate, broader than long, anterior margin notched medially, lateral margins slightly concave submedially (Figs 13, 17). Anal tube process in lateral view short, originating near basoventral angle of segment X and extending caudad, gradually narrowing with rounded apex (Figs 5, 7, 11, 12).

Female. Unknown.
