Genus Calliphora Robineau-Desvoidy, 1830

Diagnosis of genus Calliphora

The genus Calliphora shares a combination of (a) abdomen ground colour metallic blue, purple or green, mottled gold or silver or entirely orange, and (b) stem vein bare dorsally with other genera of subfamily Calliphorinae, but differs by the combination of (c) lower calypter setose dorsally, and (d) subcostal sclerite not setose (pubescent).

– Anterior spiracle regular in size, equal to or larger in width at widest part than proepisternum (Supp. file 1: Fig. S1H) ..................................................................................................................... 8

7. Postpedicel at least partially orange (Figs 2B, 3B); upper calypter with dark orange or brown fringe (Figs 1E, 4E); male terminalia with cercus hooked with a weak concave region in basal half and weak to no sclerotisation in distal half of mesohypophallus (Fig. 4F, H) ...................... clarki - group
