Measurements. Male (n=10): TL= 11.09 mm, HW= 2.15 mm, PL= 2.28 mm, PW= 3.01 mm, EL= 6.80 mm, EW= 2.24 mm. Ratios PL/PW= 0.75, HW/PW= 0.71 and EL/EW= 3.02. Female (n=10): TL= 11.36 mm, HW= 2.14 mm, PL= 2.26 mm, PW= 2.94 mm, EL= 6.96 mm, EW= 2.34 mm. Ratios PL/PW= 0.76, HW/PW= 0.72 and EL/EW= 2.98.

Diagnosis. Head metallic green, smooth with weak wrinkles and moderately spaced minute punctures. Mandibles, labrum, antennal articles I–II, pronotum lateral bead and entire legs reddish brown. Antennalarticles IV–XI dark brown. Pronotum metallic green, less cordiform, lateral margins less convex and sides more sinuous near posterior angle as compared to velocipes , basal fovea with dense setiferous punctuation near base and sparse throughout disc to apical margin. Elytra black with metallic green luster near base, epipleuron dark brown, striae with evenly spaced punctures, intervals densely setiferous punctate, microsculpture isodiametric/ granulated. Venter black more sparsely punctate anteriorly than the abdomen.

Comments. C. (Chlaeniellus) tenuilimbatus appears superficially similar to C. (Chlaeniellus) velocipes . However, it differs on the basis of prontum lateral margin black, elytral lateral margin dark brown to black; pronotum maximum width before mid-point; pronotum sides more sinuous near posterior angle; pronotal disc to apical margin sparse setiferous punctate. Where as, C. (Chlaeniellus) velocipes differs on the basis of pronotum lateral margin yellowish brown, elytral lateral margin yellowish brown; pronotum maximum width at mid-point; pronotum sides less sinuous near postero-lateral angles; pronotum uniformly setiferous punctate. This species is recorded for the first time from Pakistan. It is wide spread and collected from Chitral, Booni, Mastuj, Swat, Mansehra, Ghizer and Ghakuch in Pakistan.

Distribution. Afghanistan, Iran, Kashmir, Kyrgyzstan, Kazakhstan, Tajikistan, Turkmenistan, Uzbekistan (Anichtchenko 2017) and Pakistan (first country record).
