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). Key to genera of Australian Calliphorinae and species-groups of Calliphora 1. Subcostal sclerite setulose (Supp. file 1: Fig. S1F) .......................................................................... 2 – Subcostal sclerite pubescent or bare (Supp. file 1: Fig. S1E) ........................................................... 3 2. Eye densely and uniformly setulose (Supp. file 1: Fig. S1B) ......................... Ptilonesia Bezzi, 1927 – Eye bare or with only sparse setulae (Figs 1B, D, 2B, D) ................. Xenocalliphora Malloch, 1924 3. Male abdominal sternite 5 with postero-median margin extended into down-turned subapical spine; lower calypter bare dorsally (see Norris 1999: fig. 1h–i) ............................. Aphyssura Hardy, 1940 – Male abdominal sternite 5 with postero-median margin unmodified; lower calypter with setae dorsally ........................................................................................................................4 (Calliphora) 4. Eye densely setulose over entire surface (Supp. file 1: Fig. S1B) ............................. ochracea -group – Eye without setulae ........................................................................................................................... 5 5. Femora and tibiae at least partially orange or yellow (Supp. file 1: Fig. 1A); abdominal tergites 1+2–5 with microtomentum mottled golden at least in the lateral 0.3 (Supp. file 1: Fig. S1D), some species with contrasting median metallic patches dorsally on T 1+2– T 5 (Supp. file 1: Fig. S1C) ..... ......................................................................................................................................... stygia -group – Femora and tibiae dark brown or black (Figs 1C, 2C); abdominal tergites 1+2–5 with microtomentum mottled golden, silver or absent (Supp. file 1: Fig. S1D) ................................................................. 6 6. Anterior spiracle reduced in size, smaller in width at widest part than proepisternum (Supp. file 1: Fig. S1G; Figs 3D, 5E) ............................................................................................... 7 – 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 – Postpedicel orange, brown or black (Supp. file 1: Fig. S1I, M); upper calypter with yellow or hyaline fringe (Supp. file 1: Fig. S1G); male terminalia with weakly curved cercus (lateral view) and mesohypophallus with distinct break or very weak region of sclerotisation medially (Supp. file 1: Fig. S1J) .............................................................................................. flexipenis - group 8. Male terminalia with mesohypophallus strongly curved (c-shaped) in distal half, without break in sclerotisation (Supp. file 1: Fig. S1K) ........................................................................ sternalis -group – Male terminalia with mesohypophallus sclerotised and straight or gently curved in distal half ...... 9 9. Epandrium elongated, twice length of cercus from base to insertion point of cerci; acrophallus ~2 × as long as paraphallus; cercus broad in basal half, at least twice width at tip; surstylus distally with swollen lobe (Supp. file 1: Fig. S1N) ............................................................................ tibialis -group – Epandrium not elongated, similar in length to cercus; acrophallus equal to length of paraphallus at most extending slightly beyond tips; cercus slender for entire length, similar in width to surstylus; surstylus distally without a lobe (Supp. file 1: Fig. S1L) ............................................... typica - group
