Description.

Body length: Male 3.7-3.9mm.

General colour variable: lighter coloured specimens yellow to ochre-yellow. Vertex with borders at eyes creamy-yellowish, semilunar patch mesocaudad of ocelli creamy. Face and basal antennal segments light yellow. Eyes blackish-brown. Disc of pronotum golden-yellow, irregular arch of hypodermal pattern light-yellow in addition to three large creamy patches along anterior margin. Centre of scutellum sordid cream, scutoscutellar sulcus beige. Darker specimens brown to sordid brown, semilunar patch mesocaudad of ocelli, borders at eyes, genae, patches on pronotum and centrally on scutellum, sordid cream.

Male genitalia: Basal sternal abdominal apodemes exceeding half of segment 4 (Fig. 8). Male pygofer with about 16 rigid setae on outer and inner surface of lobe, ventral pygofer appendage slim and bent caudodorsad near base, surpassing caudal margin of lobe, tapering and sculptured with depressions subapically (Figs 5, 11-13). Subgenital plate with nearly same width in basal third, apical 2/3 gradually narrowing towards apex, A-group setae (3-4) rigid, B-group seate (15-17) small, roughly uniseriate along dorsal margin in apical half, C-group setae (13-14) arising near base of plate, sharply terminated, D-group setae roughly bi- or tri-seriate, starting caudad of C-group setae (Figs 5, 11, 18, 19). Paramere sinuate in caudal part, apically bearing 3 big teeth preceded by ca. 6 fine setae and few sensory pits (Figs 5, 11, 19, 20). Connective narrowing to deeply emarginate apex (Fig. 17). Aedeagal shaft tubular, longer than preatrium, in profile its middle part right-angled and curved caudoventrad followed by vertical apical region, gonopore large on ventral side, in ventral view aedeagus with rounded apex (Figs 5, 11, 15, 16).
