PAKISTAN • 6 ♂, 2 ♀; Punjab, Jehlum, Domaili Railway Station ; 01 Jun. 2014; Mishkat leg.; PMNH • 2 ♂; Islamabad, Faisal Mosque , Trail No. 6; 18 Apr. 2015; Mishkat leg.; PMNH • 1 ♀; Punjab, Fort Abbas, Doudla Plantation ; 13 Apr. 2009; Mishkat leg.; PMNH • 1 ♂; Punjab, Chakwal, Katas ; 30 May 2014; Mishkat leg.; PMNH • 5 ♂; Punjab, Chakwal, Dhok Tahlian Dam ; 01 Jun. 2014; Mishkat leg.; PMNH • 1 ♀; Azad Jammu & Kashmir, Mangla ; 21 Apr. 2008; Ishaq / Ahmed Zia leg. ; NIM • 1 ♀; “ Lyalpur” [ Faisalabad ]; 11 Sep. 1929; light collection; ex coll. Imp. Inst. Entomology; NHMUK (H.E. Andrewes 1945-97).

Measurements. Male (n=10): TL= 10.83 mm, HW= 2.18 mm, PL= 2.30 mm, PW= 3.04 mm, EL= 6.88 mm, EW= 2.10 mm. Ratios PL/PW= 0.75, HW/PW= 0.71 and EL/EW= 3.27. Female (n=10): TL= 10.63 mm, HW= 2.10 mm, PL= 2.10 mm, PW= 2.81 mm, EL= 6.38 mm, EW= 1.98 mm. Ratios PL/PW= 0.74, HW/PW= 0.74 and EL/EW= 3.22

Diagnosis. Head and pronotum black with metallic green blue tinge. Mandibles and labrum dark brown; palpi, antennal articles and tarsus reddish brown. Clypeus smooth, frons smooth sides with deep long setiferous puncture, vertex and neck area rugose densely covered with setiferous punctures. Pronotum almost shell shaped, apical border convex, lateral sides abruptly oblique outwardly upto midpoint and then contracted; postero-lateral angles obtuse; surface sparsely covered with deep setiferous punctures to densely covered towards basal margin; laterobasal fovae deep. Elytra matt green bluish, interval IX yellowish brown along border and expanding slightly at apex; striae punctate; intervals slightly convex densely punctate and pubescent with golden setae, microsculpture isodiametrical. Venter black with iridescent tinge but abdominal segments with wide yellowish lateral band.

Comments. Ch. (P.) puncticollis appears similar to Ch. (Chlaeniellus) nigrosuturatus Mandl, 1978 in general shape. It can be easily differentiated on the basis of dense pubescence on each tarsi dorsal side; pronotum lateral margin constant without band whereas Ch. (Chlaeniellus) nigrosuturatus tarsi without pubescence; pronotum lateral margin with narrow yellowish band. In this current study it was collected from Jehlum, Forte Abbas, Islamabad and Chakwal areas.

Distribution. Afghanistan, Iran, India (Himachal Pradesh; Uttarakhand), Laos, Nepal and Pakistan (Anichtchenko 2017; Lorenz 2018; Azadbukhsh & Rafi 2017).
