Diagnosis. Head metallic green, clypeus smooth, frons and vertex wrinkledsparsely punctate and neck wrinkled densely punctate. Mandibles, labrum, maxillary palpi first two articles 2/3 rd, labial palp article Ione third, antennal article IV–IX, all tarsus and coxae, reddish brown; maxillary palpi basal article entire, maxillary palpi terminal article one third, antennal article I, rest of legs yellowish brown. Pronotum black with metallic green tinge, quadrate, slightly rugose, anterior margin, sides moderately setiferous punctate to densely setiferous punctate at margins, basal fovea short and deep; postero-lateral angles blunt; basal border wider than apical; lateral bead reddish brown. Elytra black with metallic greenish tinge throughout, horseshoe shaped fascia/mark on each elytron extending to apex from interval III (just touching) to interval VIII then approaching to meet at apex; striae deep with uniformly spaced punctures; intervals flat, densely setiferous punctate throughout, microsculpture isodiametrical, elytra lateral border/bead reddish brown. Venter black brown.
Comments. Ch. (P.) hamifer closely resembles Ch. (P.) pictus Chaudoir, 1856 in general habitus and elytral apical maculae. It differs on the basis of head and pronotum colouration which is metallic green with very slight coppery tinge; elytra metallic green with horse-shoe shaped mark beginning from mid of interval III transversely approaching interval VIII and then running along interval IX up to apex. Ch. (P.) pictus head and pronotum black with dark metallic coppery colouration; elytra black with horseshoe shaped mark beginning from 3/4 th of interval II transversly approaching interval VIII and then running towards apex. This species is frequently encountered from Chitral to the entire Salt Range of Pakistan. Khatri et al. (2016) reported its occurance from Panjgoor-Balochistan. Its global distribution ranges from the Arab Emirates to Australia.
Distribution. Arab Emirates, Australia, Myanmar (Burma), Bhutan, China (Guangxi; Sichuan), Indonesia (Borneo), Japan, Melanesia, Nepal, Pakistan, Singapore, Sri Lanka, Thailand and Taiwan (Formosa) (Anichtchenko 2017).
