Genus Austrocyphon Zwick, 2013c

Austrocyphon includes many species. Males can be recognized by their distinctive terminalia but females have neither prehensors nor bursal sclerites. Austrocyphon papilio Zwick from Western Australia is an exception. I described elongate structures with transversely folded (concertinated) front ends in the vulvar area of individual females of several species (e.g., A. doctus (Lea) , A. tribulator Zwick: Zwick 2013c ). These objects are probably spermatophores. Meanwhile I have seen them also in females of several other genera.

However, a few species can be recognized by their dorsal colour pattern or habitus (e.g., A. pictus (Blackburn) ( Zwick 2013c: fig. 17), A. leptophallus Zwick ( Fig. 89 ; also Zwick 2013c: fig. 184), and A. curvispina ).
