Type species: Gurawa vexillum Distant, 1908 . Description. Surface of vertex, pronotum and scutellum shagreen (Plate I: A). Head wider than pronotum. Vertex subtriangular, flat, anterior margin foliaceous, lateral margins oblique and almost in line with outer margins of eye, ocellus near anterior margin of head, far from eye, eye projecting posterad beyond anterior angles of pronotum (Plate I: A–C); genae deeply notched below eye, extended beyond anteclypeus (Plate I: D). Pronotum distinctly carinate laterally, more than twice as broad as long (Plate I: A–C). Forewing passing abdominal apex, appendix absent, apices not overlapping, texture coriaceous, veins distinctly elevated (Plate I: A). Hindwing reduced. Profemur setal row AV with 13–15 similar peg-like setae; AM1 present ( Figs 2A–B ). Foretibia rounded in cross section, dorsal macrosetal formula 1+1 ( Figs 2C & 2D, 2E & 2F ). Hind femur setal formula 2+0 ( Fig. 2G ). Hind tibia setal row AD with approximately 6–7 long stout setae and 2–5 shorter setae between each long seta ( Fig. 2H ); AV with apical seta larger than basal ( Fig. 2H ); pecten with several normal macrosetae and 2 platellae ( Fig. 2I ); PD with appproximately 9–11 macrosetae, 0–2 shorter setae between each long seta, hardly as long as those of AD ( Fig. 2J ). Hind tarsomere I nearly parallel-sided, with dorsoapical pair of setae, and ventral scattered setae, and 4 patellae in pecten. FIGURE 1. Gurawa minorcephala Pruthi. A –B: male pygofer side, lateral view; C: valve and subgenital plate, ventral view; D: style, dorsal view; E: connective, dorsal view; F & G: aedeagus, caudal and lateral view, respectively. PLATE I. Gurawa minorcephala Pruthi. A –B: habitus, dorsal view; C: habitus, lateral view; D: face; E: the end of female abdomen, ventral view; F: first valvula; G: detail of first valvula; H: second valvula; I: detail of second valvula. Male pygofer without macrosetae, basolateral cleft absent or not membranous ( Figs 1A–B ). Valve triangular ( Fig. 1C ). Subgenital plate triangular, short, without macrosetae ( Fig. 1C ). Connective with anterior arms closely appressed with distinct stem ( Fig. 1E ). First valvula dorsal sculpturing granulose to maculose, slightly submarginal for most of length (Plate I: F–G). Second valvula abruptly broadened ~1/2 its length from base, with small obliquely triangular dorsal teeth over nearly apical half (Plate I: H–I). Distribution. China ; India ; Oriental Region.
