( Fig. 7d )

Harpalus leucops Wiedemann, 1823: 52 ; Chlaenius aeruginosus Chaudoir, 1856: 271 ; Chlaenius hauseri Jedlicka, 1931d: 135 ; Chlaenius mussardi Saha & Sengupta, 1979: 423 ; Chlaenius barmatius Saha, 1984: 99 .

Material examined. PAKISTAN • 1 ♂; Punjab, Attock, Humak ; 29 May 2014; Mishkat leg.; PMNH • 1 ♀; Islamabad, Trail No. 6, Faisal Mosque ; 28 Jun 2014; Mishkat leg.; PMNH • 1 specimen; “India, North West Province” ( Pakistan , Khyber Pakhtunkhwa); NHMUK (H.E. Andrewes Collection 1945-97)

Measurements. Male (n=5): TL= 12.7 mm, HW= 2.59 mm, PL= 2.60 mm, PW= 3.77 mm, EL= 7.67 mm, EW= 2.25 mm. Ratios PL/PW= 0.68, HW/PW= 0.68 and EL/EW= 3.40. Female (n=5): TL= 12.82 mm, HW= 2.62 mm, PL= 2.74 mm, PW= 3.82 mm, EL= 7.57 mm, EW= 2.47 mm. Ratios PL/PW= 0.71, HW/PW= 0.68 and EL/EW= 3.06

Diagnosis. Head metallic blue-green with slight tinge of bronze colour, clypeus smooth, frons and vertex slightly wrinkled moderately punctate. Maxillary and labial palpi terminal article tip and antennal article Ireddish brown; rest of antennal articles, maxillary palpi, labial palpi and legs black to brown. Pronotum metallic blue-green with slight tinge of bronze colour, apical border very convex, moderately covered with deep setiferous punctures to densely covered with setiferous punctures; both angles blunt, setae golden. Elytra black with slight metallic green tinge, striae deep and punctate, intervals flat, densely setiferous punctate thoughout, microsculpture isodiametrical. Venter blackish brown.

Comments. Ch. (P.) leucops is very close to Ch. australis Dejean, 1831 in general habitus and colouration. It differs on the basis of pronotum more convex, densely covered with slightly smaller sized setiferous puctures; elytra slightly elongated; head and pronotum metallic blue green with slight tinge of bronze colour; elytra slightly greenish black and densely covered with golden pubescence. In Pakistan, leucops is recorded from the Islamabad and Attock areas. This is the first time this species is reported from Pakistan. It is widely distributed from Pakistan to all other south-east Asian countries.

Distribution. China, Indonesia (Java; Lesser Sunda Islands.; Sumatra), India, Japan, Kashmir, Laos, Malaysia, Myanmar ( Burma), Nepal, Pakistan (first country record), Philippines, Sri Lanka, Thailand, Taiwan and Vietnam (Anichtchenko 2017; Lorenz 2018).
