Ochraceous with reddish brown tinge. Eyes chocolate brown. Male abdominal terga 1–4 and sterna 2 and 3 with well developed apodemes. Male genitalia: Pygophore with ventral process arcuate, with elongate oblique furrow in middle section, expansion less prominent dorsal margin with dilation showing a cavity ( Fig. 100) surface with ridges. Apopysis style of type1. Aedeagus with short preatrium, having almost straight ventral margin; aedeagal shaft in lateral aspect with rather straight dorsal margin, distal 0.25 upturned, narrower with transverse rugae, in caudal aspect basal half of shaft broader than apical region with a constriction in middle. Measurements: Male 10.5 mmlong, 2.4–2.5 mmwide across eyes, 2.9–3.2 mmwide across hind margin of pronotum.
Material examined: Holotypeď, India: West Bengal: Sukna, 500ft( 152 m), E. Himalayas, 1.vii.[19]08,N. A[nnandale] ( BMNH). Paratype1 ď, India: West Bengal: Margherita, W. Doherty, 9050/8 ( BMNH).
Remarks: K. venican be readily recognized by its dorsal margin of aedeagal shaft being almost straight in basal 0.75; the ventral margin of the preatrium is also straight. The shape of the ventral pygophore process of the paratypemale is slightly different, being much wider basally and more pointed distally; however, the aedeagus is similar except that the apical 0.25 region is slightly narrower than in the holotype. The species K. bakeri, K. deltaand K. veniform a very close-knit group of species of Krisnaconsidering the shape of the aedeagus and ventral pygophore process. However, they differ in the detailed structure of the aedeagus.
