Gurawa longispina sp. nov.

Figs. 1A–D , 3A–F , 5A

Length. Male: 3.1–3.3mm; female: 3.6mm.

Pale ochraceous in general coloration. Vertex with indistinct median brown stripe with converging brown arms near anterior margin, lateral margin with fuscous spots. Pronotum with 3–4 dark brown lateral spots on each side ( Fig. 1A ). Scutellum pale with median ridge pale ochraceous, lateral ends with or without dark brown longitudinal stripe. Face with or without dark brown mottling, antenna with brown elongated spot at base ( Fig. 1C ).

Vertex 1.5x wider than median length, medially 1.5x longer than median length of pronotum. Crown constricted laterally and divided into anterior and posterior small lobes near ocelli, pronotum 2.6x wider than long; hind femoral macrosetae 2+0. Forewing nearly 3x longer than wide.

Male genitalia. Pygofer with posterior margin broadly rounded, lobe-like, ventral margin concave ( Fig. 3A ). Valve triangular, nearly 2.4x as broad as median length ( Fig. 3B ). Subgenital plates with inner margin as long as broad at base ( Fig. 3B ). Style with preapical lobe long, apophysis nearly 2x longer than preapical lobe with obvious tooth on ventral margin near basal half ( Figs. 3B , 5A ). Connective with stem as long as arms ( Fig. 3F ). Aedeagal shaft slightly narrowed towards apex with parallel margins, serrations absent, lateroapical spines long, slender, curved anteromesad ( Figs. 3C–F ), gonopore subapical on dorsal surface.

Female. Seventh sternum nearly 1.3x as wide at base as long, posterior half slightly narrowed towards distal margin, posterior margin with pair of large, irregularly rounded lateral lobes separated by narrow concavity with short median angulate projection ( Fig. 1D ).

Type material: Holotype: ♂, Pakistan, Abbottabad City , 1256m, 4 August 2016, Coll. Hassan Naveed . Paratypes: 1♀, same data as holotype; Azad Jammu & Kashmir: Rawalakot, 2♂, 1638m, 11 August 2017, Coll. Hassan Naveed ; Azad Jammu & Kashmir: Toli Pir, 1♂, 1♀, 2682m, 12 August 2017, Coll. Hassan Naveed .

Remarks. This new species is similar to G. constricta in external appearance but has a much shallower constriction of the lateral margins of the crown. This species belongs to the group with the crown constricted, that includes G. ceylonica and G. constricta . These species have very similar structure of the aedeagus, with a pair of long apical spines and a short lobe between them. The new species has unusually long apical processes of the aedeagus compared to the remaining species.

Etymology. The epithet longispina refers to the apical spine-like processes of the aedeagus.
