Styringomyia bancrofti EDWARDS ( Figs 7-12 )

Styringomyia bancrofti EDWARDS, 1914: 222 . Holotype: Australia, Queensland, Burpengary, Dr. T.L. Bancroft; in NHM; not seen.

M a t e r i a l e x a m i n e d. 1 paratype ♂: data as in holotype (AC). Two females recorded as S. bancrofti from Queensland, Meringa near Cairns by ALEXANDER (1920) are not considered here as males are not available from this locality.

The most diagnostic characters specified in the original Description are: "Legs with all the dark rings distinct, complete, the tips of all tarsal joints dark. Wings with normal venation and markings. In the hypopygium the upper claspers very much reduced."

D i s c u s s i o n.Themalesof Styringomyia bancrofti , S. baroalba nov.sp., S. collessi nov.sp., and S. remex nov.sp. share a bifid apex of sternite 9, a mesal expansion and subconical gonocoxites with a rather thick apical spine and complex gonostyli. The prominent element of the gonostyli bears long distinct setae along posterior margin only in S. bancrofti and it is produced only mesally as in S. collessi and S. remex versus produced mesally and laterally (double-winged) in S. baroalba .
