( Fig. 8c )

Chlaenius chlorodius Dejean, 1826: 365 .

Material examined. PAKISTAN — Khyber Pakhtunkhwa • 1 ♀; Mansehra, Shinkiari; 30 Aug. 2007; Ahmed Zia leg.; Chlaenius (Amblyenius) chlorodius Mishkat Ullah 2017 det.; NIM • 1 ♂, 2 ♀; “N.W. India” [Khyber Pakhtunkhwa]; B.M. 1884-19.

Measurements. Male (n=1): TL= 12.6 mm, HW= 2.62 mm, PL= 2.62 mm, PW= 3.83mm, EL= 7.66 mm, EW= 2.56 mm. Ratios PL/PW= 0.68, HW/PW= 0.68 and EL/EW= 2.98. Female (n=2): TL= 12.81 mm, HW= 2.55 mm, PL= 2.79 mm, PW= 3.8 mm, EL= 7.65mm, EW= 2.57 mm. Ratios PL/PW= 0.73, HW/PW= 0.67 and EL/EW= 2.97.

Diagnosis. Head metallic green with reddish yellow green luster; labrum deeply emarginate at apex or bilobed; mentum median tooth small and apex slightly emarginate; palpi terminal article apex coniform, sub-cylindrical and truncate. Antenna, labrum, mandibles and legs yellowish brown. Pronotum green with reddish yellow green luster, quadrate shaped, moderately punctate pubescent, densely punctate at basal region. Elytra black with green luster at base, laterally and at apex, without spot, intervals smooth with a longitudinal row of punctures on both sides of each stria.

Comments. Ch. (P.) chlorodius closely resembles Ch. (A.) luculentus Andrewes, 1920 in general habitus and colouration. It differs on the basis of antennal colouration article I–XI reddish brown where as antennal article IV– XI blackish in latter; pronotum sparsely punctate without tansverse wrinkles where as pronotum densely punctate with tranverse wrinkles in luculentus . Pronotum lateral margin not sinuate before base and postero-lateral angles rounded where as pronotum lateral margin slightly sinuate near base and postero-lateral angles sharp, protruding outward in luculentus . Elytra basal margin and stria VIII densely punctate where as elytra basal margin and stria VIII impunctate in luculentus . This species is widely distributed throughout India but only reported from Mansehra in Pakistan. This is the first time this species is recorded from Pakistan.

Distribution. India (Uttarakhand), Nepal (Anichtchenko 2017; Kirschenhofer 2017; Lorenz 2018) and Pakistan (first country record).
