Measurements. Male (n=10): TL= 13.03 mm, HW= 2.55 mm, PL= 2.67 mm, PW= 3.69 mm, EL= 8.66 mm, EW= 2.84 mm. Ratios PL/PW= 0.72, HW/PW= 0.69 and EL/EW= 3.04.

No females were studied / available for study.

Pronotum black with metallic coppery to greenish luster; surface smooth with setiferous punctures dense near base and moderate near apical margin. Apical margin convex basal margin slightly concave, lateral margin rounded except latero-basal angle slightly obtuse. Elytra black, humeral edges dilated to a rounded mark, median transverse band narrowed near the border expands on the disc as slightly round mark, the anterior apical mark round and spread over intervals III–V, elytra lateral border yellowish brown, striae strongly punctate; interval flat, densely covered with setiferous punctures, microsculpturing transversely meshed.

(C.) scapularis, elytra humeral edges dilated to a rounded mark, median transverse band narrowed near the lateral border expanding on the disc as slightly round mark, the pre-apical mark round and occupies intervals III–V, elytra lateral border entirely yellowish brown.

This species is well distributed within the area between Pakistan and Sri Lanka.
