Grammacephalus punjabensis Shah & Duan sp. n.

( Figs 11–12 )

Measurement. Male: 5.5 mm.

Coloration and morphology. Yellowish brown ( Fig. 11 A–C). Crown dark brown with median longitudinal white stripe reaching tip of anterior margin, also with pair of lateral ochraceous stripes, pair of posterior yellowish spots present on each side of median white stripe. Eyes color tinged with red ( Fig. 11A, C ). Face whitish yellow with brownish narrow band along anterior margin ( Fig. 11D ). Pronotum with pale irregular spots, as well as with bright median stripe. Mesonotum and scutellum yellowish brown with pale spots ( Fig. 11A, C ). Femora and tibiae with dark brown marks ( Fig. 11B ). Crown narrower than pronotum, subconical, longer than 2x width between eyes ( Fig. 11A, C ). Anteclypeus with submedian constriction, apex extending beyond normal curve of genae ( Fig. 11D ). Pronotum shorter than crown. Mesonotum and scutellum nearly as long as pronotum ( Fig. 11A, C ).

Male genitalia. Pygofer lobe broad basally while narrowed towards posterior margin, with posterior short setae covering membranous area, tuft of long microsetae present near posterior margin. Pygofer process long, directed postero-dorsally, surpassing pygofer lobe, with subapical posteroventrally directed spine near apex ( Fig. 12A, 12B ). Subgenital plate triangular, broad basally, tapered towards apex with with lateral uniseriate macrosetae. Style elongated, with small apophysis ( Fig. 12D ). Connective Y-shaped with arms well separated, stem short ( Fig. 12E, F ). Aedeagus broad at base with well-developed dorsal apodeme, gonopore apical, aedeagal shaft slightly narrowed at mid-length, widened near apex in dorsal view, sinuate and evenly tapered distally in lateral view ( Fig. 12 E–G).

Material examined. Holotype: male, Pakistan: Punjab: Murree Hills , 33°54′23.508 N, 73°23′ 37.284 E, 2000m, Sweeping hand net, 23 July 2018, coll. Bismillah Shah.

Etymology. This species is named for Punjab province in Pakistan where the type specimen has been collected.

Remarks. This species resembles G. furcatus in external characters but can readily be distinguished by the subgenital plate with lateral margins not incurved at mid-length and the aedeagus without dorsal apical processes.
