Stirellus kumratensis sp. nov.

( Figs. 5, 6 , 9–15)

Measurements. Body length (including forewing): male 3.57–3.6 mm.

Coloration. Dark brown to ochraceous ( Fig. 5 ). Crown with orange bands along anterior margin of eyes ( Fig. 5 ). Pronotum dark brown except anterior mid margin with borders orange ( Fig. 5 ). Face with dark brown band just beneath eyes which leads to antennal ledges ( Fig. 6 ). Clypeus as well as anteclypeus light brown to brownish yellow, each with pair of dark brown spots ( Fig. 6 ). Forewings with brown to dark brown spots ( Fig. 5 ).

Morphology. Head nearly subequal in width to pronotum, subconical, anterior margin rounded to face, acutely angled ( Fig. 5 ). Crown slightly longer than width between eyes ( Fig. 5 ). Pronotum median length, nearly as long as median length of crown ( Fig. 5 ). Mesonotum and scutellum shorter than pronotum ( Fig. 5 ). Forewings macropterous, may or may not extend beyond apex of abdomen ( Fig. 5 ).

Genitalia. Pygofer side longer than high, with two macrosetae near dorsal margin, anteriorly broad, strongly declivous caudally, ventral margin slightly notched near midlength, preapical tooth well developed and visible in dorsal aspect (Figs. 9–10). Subgenital plates convexly rounded laterally, slightly elongate, macrosetae uniseriate laterally (Fig. 11). Style apophysis small, with pointed apex, digitate, curved laterally (Fig. 13). Connective ‘H’- shaped, with stem shorter than anterior arms (Fig. 12). Aedeagal shaft long, tapered towards apex dorsally, with ‘pear’-shaped or spine-like apex, strongly bent near base laterally (Figs. 14–15).

Type material. Holotype: ♂, Pakistan, Khyber Pakhtunkhwa, Kumrat Valley, 2359m, July 2016, Coll. Hassan Naveed. Pakistan, Khyber Pakhtunkhwa, Naran City, 2409m, July 2016, Coll. Hassan Naveed. 3♂, Pakistan, Khy- ber Pakhtunkhwa, Kumrat Valley , 2359m, August 2018, Coll. Hassan Naveed (all NWAFU).

Remarks. This species closely resembles S. laetus ( Melichar, 1903: 202) but differs in having the vertex with a pair of longitudinal orange stripes along the mesal margins of the eyes, the pygofer with macrosetae, the style apophysis small and the aedeagus with a spine-like apex.

Etymology. The species epithet is based on the type locality, Kumrat Valley.
