Tasnimocerus sindhensis sp. nov.

( Fig. 1 )

Description. Length: ♂, 5.6 mm;

Colour yellowish brown with dark brown markings. Three irregular markings on crown. Clypellus with dark brown margins. Frontoclypeus with numerous irregular markings. Scutellum with basal dark brown triangles, and brown marking either side of midline. Forewing veins alternately with dark and pale brown markings.

Vertex and pronotum with fine transverse rugae. Head wider than pronotum. Clypellus very wide at base. Narrow forewing appendix ending at apical cell 2; 3rd and 4th apical cells wider than rest.

Male genitalia: Anal tube with lateral slightly sinuate process ( Fig. 1 f). Pygofer narrowed caudally with stout spine at apex ( Fig. 1 e–f). Subgenital plate turned upward at apex, with few short hairlike setae, longer than pygofer apex ( Fig. 1 f). Style slender, long, turned upwards, with fine setae at midlength ( Fig. 1 j, m). Connective, short, stout rather Y-shaped with bilobed distal end, and dorsal keel ( Fig. 1 j–k). Aedeagus long, straight, with fine laterally directed setae in basal half, thereafter turned ventrally and strongly upturned apically, with one pair of anteriorly directed processes arising dorso-laterally with apices crossing each other ( Figs 1 l-o).

Female genitalia: Hind margin of seventh sternite produced and narrowed caudally with median U-shaped notch. Serrate edge of second pair of valvulae occupying almost 0.75 total length.

Measurements: (single ♂) Total body length, 4.6 mm; length of forewing, 3.5 mm; width of crown across eyes, 1.7 mm; width of scutellum at base 0.9 mm; length of scutellum 0.65; mm width of pronotum 1.5 mm.

Material examined. Type Material: Holotype ♂, Pakistan: Tandojam, 14.x.2007, I. Khatri ( BMNH); paratypes, 2 ♀ same data as holotype ( BMNH); 1 ♀ same data as holotype (IKC).

Remarks. Tasnimocerus sindhensis sp. nov. differs from T. clypeatus Ghauri by: 1) anal collar process much shorter; 2) processes of aedeagal shaft more distal, more proximal to each other and shorter and crossing over each other at apex; 3) aedeagal shaft more strongly hooked distally.
