(Fig. 4b)
Chlaenius laeviplaga frater Chaudoir, 1876: 261; Chlaenius laotinus Andrewes 1919: 14.; Chlaenius lindemannae Mandl 1983: 434.
Material examined. PAKISTAN • 2 ♂, 1 ♀; Punjab, Chakwal, Dhok Tahlian Dam;, 01 Jun. 2014; Mishkat leg.; PMNH • 2 ♂, 1 ♀; Islamabad, F-9 Park Stream; 16 Nov. 2014; Mishkat leg.; PMNH • 2 ♂; Azad Jammu & Kashmir, Mangla Dam; 03 Apr. 1982; Anonomous; PMNH • 1 ♂; Azad Jammu & Kashmir, Mangla; 21 Apr. 2008; Ishaq / Ahmed leg.; NIM.
Measurements. Male (n=10): TL= 11.24 mm, HW= 2.20 mm, PL= 2.19 mm, PW= 2.87 mm, EL= 7.16 mm, EW= 2.31 mm. Ratios PL/PW= 0.76, HW/PW= 0.76 and EL/EW= 3.04. Female (n=10): TL= 10.54 mm, HW= 2.11 mm, PL= 2.08 mm, PW= 2.71 mm, EL= 6.48 mm, EW= 2.17 mm. Ratios PL/PW= 0.76, HW/PW= 0.77 and EL/EW= 2.97.
Diagnosis. Head metallic bluish green; frons, vertex and neck with minute punctures. Labrum, antennalarticles I–III, maxillary palpi, labial palpi pronotal lateral bead and entire legs yellowish brown; Antennal articles IV–XI light reddish brown; mandibles reddish brown. Pronotum metallic blue green, cordiform, lateral margins convex and sides less sinuous near postero-lateral angle as compared to Chlaenius flavipes, setiferous punctures dense arround basal fovea near base and sparse throughout disc to apical margin. Elytra matt black, lateral margin yellow brown, elytra apex with crescent shaped yellowish-brown mark. Striae evenly spaced punctate, intervals flat densely setiferous punctate, microsculpture isodiametric/granulated. Venter black less punctate anteriorly than the abdomen.
Comments. This species very closely resembles C. (Chlaeniellus) vestitus Paykull, 1790 in general appearence particularly pronotum lateral margin band, punctuation pattern and elytral apical band colouration. It differs on the basis of pronotum lateral margin slightly sinuate before postero-lateral angles; pronotum sides and median line/groove with two intertwined lines either side densely punctuate leaving a smooth elongated space inbetween; pronotum basal margin at mid-point without punctuation but finely striated; elytra dark. Where as in vestatis, pronotum lateral sides more sinuated before postero-lateral angles; pronotum densely covered with setifrous punctures (increasing in density from apex to base); pronotum basal margin punctate; elytra metallic green. This species was collected from Chakwal, Islamabad and Mangla (Azad Jummu & Kashmir).
Distribution. China, India, Laos and Pakistan (Anichtchenko 2017).
