( Fig. 3d )

Chlaenius lafertei Guérin-Méneville, 1843: 36 ; Chlaenius diffinis LaFerté-Sénectère, 1851: 241 ; Chlaenius centromaculatus Chaudoir, 1856: 218 ; Chlaenius maculipennis Motschulsky, 1865: 341 .

Material examined. PAKISTAN — Punjab • 1 ♂; Rawalpindi, Wah Cantt; 27 Jul. 2016; M. Suleiman leg.; PMNH • 2 ♂, 1 ♀; “Lyallpur” [Faisalabad]; 20 Aug. 1923; D. Nath leg.; labeled with lafertei det.; preserved by Imperial Bureau of Entomology ; NHMUK (British Museum 1927-85) .— Khyber Pakhtunkhwa • 1 ♂, 2 ♀; “ N.W. India ” [Khyber Pakhtunkhwa]; NHMUK (B.M. 1884-19)

Measurements. Male (n=10): TL= 13.74 mm, HW= 3.14 mm, PL= 3.02 mm, PW= 4.20 mm, EL= 8.00 mm, EW= 2.52 mm. Ratios PL/PW= 0.71, HW/PW= 0.74 and EL/EW= 3.19.

No females were studied / available for study.

Diagnosis. Head black with metallic coppery greenish luster, stongly wrinkled and densely punctate; Mandibles, maxillary palps, labial palps, antennal articles II–XI, pronotum lateral bead/margin, all knees, all tarsus, reddish brown; labrum, antennal article I, femora, three elytral marks flavous/yellowish brown. Pronotum black with metallic coppery greenish luster, rugose punctate and setiferous fovate; anterior margin slightly emarginate than posterior border margin. Elytra black, base and lateral border with green-bronze luster; striae with equally spaced punctures, intervals densely punctate with setiferous puntures, microsculpture finely granulated with isodiametrical mesh, median mark from interval IV–VIII with uneven/serrated margin; second mark minute on interval III, third mark oblique on apical margin. Elytral lateral border black.

Comments. Ch. (Ch.) lafertei slightly resembles Ch. (Ch.) scapularis Chaudoir, 1876 in body shape and colouration but differs on the basis of elytral maculation. In Ch. (Ch.) lafertei , elytra with three marks, median mark from interval IV–VIII with uneven/serrated margin; second mark minute on interval III, third mark oblique shaped on apical margin. While in Ch. (Ch.) scapularis , elytra humeral edges dilated to a rounded mark, median transverse band narrowed near the lateral border expands on the disc as slightly round mark, the pre-apical mark round and spread over intervals III–V, elytra lateral border entirely yellowish brown. Ch. (Ch.) lafertei is widely distributed in India, Sri Lanka and Pakistan. In this current study, it was reported from Rawalpindi, Faisalabad and Khyber Pakhtunkhwa in Pakistan.

Distribution. India, Sri Lanka (Anichtchenko 2016; Lorenz 2018) and Pakistan ( Azadbakhsh & Rafi 2017).
