Genus Cephalochrysa Kertész, 1912 

Fig. 3View Figure 3

Cephalochrysa Kertész, 1912: 99  . Type species Sargus hovas Bigot, 1859  , by original designation. See Woodley (2001: 186) for full synonymy.

Diagnosis. Moderately sized (length 7 mm), metallic purplish blue flies, with the occiput well-developed dorsally in females, and ocelli in the form of an equilateral triangle. Regarding the Australian fauna, it is most similar to Microchrysa  , but can be distinguished by the: larger size; head dorsoventrally compressed in anterior view, about 0.6 times as high as wide; lower frons with a distinct triangular callus diverging ventrally towards base of antennae; basal complex of antennal flagellum somewhat large; and more strongly developed veins M 2, M 3, and M 4.

Distribution. Bathurst Island, NT, new distribution ( Fig. 2View Figure 2).

Remarks. Sargus gselli Hill, 1919  is congeneric with Cephalochrysa  , sharing the following: head being much wider than high, ocelli forming an equilateral triangle and occiput without a posteriorly projecting fringe of hair-like setae. The general appearance of S. gselli  is extremely similar to other species of Cephalochrysa  known from Pacific islands, as well as the type species. Therefore, we transfer this species from its previous position in Sargus  to become Cephalochrysa gselli ( Hill, 1919)  comb. nov., the first record of Cephalochrysa  from Australia.
