Guheswaria brevicula   sp. nov.

( Figs 20–31 View FIGURES 20 – 31 )

Description. Body translucent whitish overall. Vertex with two round opaque white patches between coronal suture and eyes. Pronotum with two symmetrical L-shaped opaque white patches. Scutellum opaque whitish medially; triangles pale yellow, terminal part of scutellum yellow. Forewing with basal half mostly opaque ivory, with large transverse reddish-brown medial band, apical cells transparent and infumated lightly; 1st apical cell smallest, 2nd apical cell largest ( Figs 20–22 View FIGURES 20 – 31 ).

Abdominal apodemes nearly extending to apex of 7th segment. Pygofer side with several rigid setae at hind margin, and with large triangular lobe at ventro-caudal angle ( Figs 23, 24 View FIGURES 20 – 31 ). Subgenital plate with triangular lateral protrusion subapically, with 2 small rigid setae and 1 peg-like seta apically ( Figs 25, 26 View FIGURES 20 – 31 ). Paramere with lateral margin broadly rounded distad of connective, medial margin with several irregularly arranged sensory pits, apex curved slightly and abruptly tapered ( Fig. 28 View FIGURES 20 – 31 ). Aedeagal shaft bending gently and inflated near midlength in lateral view, with two pairs of processes; apical ventral processes long, slender and asymmetrical, one serrate apically and extended laterad, other curved to shaft; dorsal processes near midlength short and thin ( Figs 29–31 View FIGURES 20 – 31 ).

Measurement. Male 2.76 mm and female 2.95 mm (including wing).

Type material. Holotype, ♂, Hunan Prov., Chenzhou, Mangshan , 31.VII.1985, coll. Zhang Yalin & Chai Yonghui   . Paratypes, 2♂♂ 22♀♀, same data as holotype   ; 1♂ 5♀♀, 30.VII.1985, same locality and collectors as holotype   .

Notes. The reddish-brown pattern and genital characteristics of the new species are unique in the genus Guheswaria   excepting that the crown with two large white patches and shape of connective are similar to G. linguplata Thapa.  

Etymology. The species name is derived from a combination of the Latin prefix “brevi-” (short) and the Latin suffix “-cula” (small) which refers to caudal part of paramere short.
