Calliphora xanthocera Malloch 1927

Calliphora xanthocera Malloch, 1927 Fig. 5A–H Diagnosis This species can be distinguished from other members of the clarki -group by the unique combination of the basicosta dark brown or black; arista plumose, 1.5× length of postpedicel; acrostichal setae 2+3; abdominal tergites with very weak or no microtomentum; pleural suture between anepisternum and anepimeron pronounced, dark red-brown, distinct from the ground colour of the pleura.

Male HEAD. Scape and pedicel dark brown. Postpedicel twice length of pedicel, orange with slight darkening in anterio-lateral 0.25, with white microtomentum (most visible when viewed dorsally). THORAX. Anterior spiracle orange, reduced, smaller than proepisternum. Posterior spiracle complete, dark brown, contrasting in colour to anterior spiracle. Pleural suture between anepisternum and anepimeron pronounced, dark red-brown, distinct from ground colour of pleura. CHAETOTAXY. 4 strong basal postpronotal setae; 1 pair of discal scutellar setae. WING. Basicosta black or dark brown. Upper calypter white, with contrasting brown margin. ABDOMEN. T1+2–T5 metallic green, with no microtomentum. MALE TERMINALIA. Cercus. Equal in length to phallus; in lateral view, hooked with weak concave region in basal half; in posterior view, fused in proximal 0.30. Surstylus. Equal in length to cercus, setose; in lateral view, curved slightly downwards; in posterior view, curved slightly towards phallus. Phallus. In lateral view, epiphallus equal in length to post-gonite, hooked in distal 0.10. Pre-gonite half of length of post-gonite, triangular. Post-gonite curved, with broad rounded tip. Hypophallic lobe serrated on anterior margin, sclerotised for entire length. Paraphallus weakly curved, not reaching posterior margin of hypophallic lobe, tip of paraphallus hooked. Acrophallus straight; mesohypophallus weakly sclerotised in distal half, with small break, then sclerotised in proximal half. Female External morphology of the female is identical to the male, except in the following respects: HEAD (Fig. 5D). Fronto-orbital and parafacial plate with gold microtomentum, one pair of outer vertical setae. ABDOMEN. S5 uncleft. Ecology Unknown. Distribution AUSTRALIA: NSW and VIC.
