Measurements. Male (n=10): TL= 13.02 mm, HW= 2.36 mm, PL= 2.53 mm, PW= 2.82 mm, EL= 7.89 mm, EW= 2.27 mm. Ratios PL/PW= 0.89, HW/PW= 0.83 and EL/EW= 3.47. Female (n=10): TL= 13.16 mm, HW= 2.43 mm, PL= 2.64 mm, PW= 2.80 mm, EL= 7.98 mm, EW= 2.36 mm. Ratios PL/PW= 0.93, HW/PW= 0.86 and EL/EW= 3.37

Diagnosis. Body metallic violet and oblong. Head and pronotum narrower than metanotum/elytra. Clypeus, frons, vertex and neck surface with minute punctures and sparsely covered with wide deep setiferous punctures posteriorly. Labrum, mandibles, maxillary palpi, labial palpi and antennal articles dark brown; legs slender and black. Pronotum wider than long, antero-lateral angles blunt and postero-lateral angles slightly acute/sharp; lateral sides 3/4 th convex and basal 1/4 th constricted obliquely; median furrow finer and sides with transverse striae/wrinkles, apical and basal margin straight; surface densely covered with minute punctures and moderately with wide/deep setiferous punctures; slight isodiametrical microscuplture along basal margin. Elytra oval and slightly flat; humeral angles drooped; striae deep and punctate; intervals convex/raised, densely covered with minute punctures, microsculpture isodiametric, each lateral side with row of seta bearing punctures.

Comments. Ch. (S.) kashmiricus closely resembles Ch. (S.) coeruleus ( Steven, 1809) in general habitus. It can be differentiated on the basis of the following pronotum slightly transverse, sparsely covered with fine punctures and wrinkles across base and lateral side; head only sparsely punctate between eyes; dorsum violet. In Ch. (S.) coeruleus , pronotum more tranverse, densely covered with pucntures and base without wrinkles; head densely punctate posterior to eyes; dorsum bluish. In this study, Ch. (S.) kashmiricus was mostly collected along the bank of streams and rivers in mountainous areas of northern Pakistan (Swat, Mansehra, Chitral, Ghizer, Gilgit and Hunza).

Distribution. China, Kashmir and Pakistan (Anichtchenko 2017).
