Diagnosis
Eyes not hairy; metasomal bands gold; metasoma usually with large areas of orange-brown on T1,2; malar space very short. Male metasoma noticeably slender; S7 with sinuate posterior margin (Fig. 72). Female clypeus usually flattened sagittaly.
Variation
The species is rather variable in colour. A long series of specimens collected near Norseman contained examples with and without orange-brown on the metasoma while all eight specimens collected at Kalamunda National Park were without orange-brown and had silver metasomal bands. The body lengths of the latter specimens were on average 1 mm greater than for the former. Females from Bullfinch and Lake Gilles had red-brown rather than orange-brown markings and the clypeus was not flattened. When associated males are available, the last two may warrant classification as a separate species or subspecies. Variation in the shape of the posterior margin of S7 of males was also observed between specimens having of the typical colour form.
