Figs. 1E–H ; 4A–E ; 5B

Gurawa minorcephala Pruthi, 1930: 29 , Plate II-Figs. 10, 10a, 10b, Text-Figs. 41–42; Zahniser, 2008: 22, Figs. 77–85; Dai, Xing & Li, 2011: 38, Fig. 1 ; Duan & Zhang, 2012: 42 –44, Plate I-Fig. 1; Viraktamath & Gnaneswaran, 2013: 199 –200, Figs. 22–29, 41, 55–58.

Length. Male: 4.3mm; female: 4.9mm.

Ochraceous brown. Vertex with a reddish brown median stripe ( Fig. 1E ). Pronotum pale with irregular brown spots. Scutellum at anterior margin with dark brown lateral band. Face yellowish brown, clypeus and anteclypeus with dark brown spots, antenna with dark brown elongated spot at base ( Fig. 1F ).

Vertex slightly more than 1.5x wider than its median length, medially 1.2x longer than median length of pronotum. Pronotum nearly 2.5x wider than longer; hind femoral spinulation 2+0. Forewings slightly short, nearly 2.2x longer than wider; hind wings reduced.

Male genitalia. Pygofer side with posterior half concave on dorsal margin, posterior margin convex, ventral margin slightly inclined ( Fig. 4A ). Valve triangular, nearly 2x as broad as median length ( Fig. 4B ). Subgenital plates with inner margin shorter in length than width at base ( Fig. 4B ). Style with preapical lobe short, apophysis digitate, gradually narrowed towards apex with basal tooth followed by 3–4 small teeth on ventral margin ( Figs. 4B , 5B ). Connective Y-shaped with stem shorter than arms ( Fig. 4B ). Aedeagal shaft with few small teeth on laterodorsal margin ( Fig. 4E ), lateroapical spines short, slightly close together, with three hair-like small setae on apical lobe ( Fig. 4C–D ), gonopore subapical on dorsal surface.

Female. Seventh sternum as shown in Fig. 1H .

Material examined: 1♂, 1♀, Pakistan, Punjab: Murree Hills , 2291m, 25 August 2017, coll. Hassan Naveed.

Remarks. This species is a variant of G. minorcephala Pruthi. Wing polymorphism is very common among other ground dwelling leafhoppers but has not previously been reported in this species.
