Figs 2d, 7, 19, 33

Type specimens. HOLOTYPE ♂ Cooper Creek , 19 km E by S of Mt Borradaile, Northern Territory (12°6'S 133°4'E), 5–6 Jun 1973, J.C. Cardale in ANIC (32-067029) GoogleMaps   . PARATYPES (5♀♀, 7♂♂, all in ANIC) same data as holotype GoogleMaps   (32- 067023–028, 32-067030–035).

Diagnosis. Female frons and scutum dark with a metallic sheen; clypeus, supraclypeal area and lower paraocular area yellow; apical margins of metasomal terga translucent. Distinguished from E. chalcosoma   by yellow in paraocular areas and from E. purpurea   by yellow supraclypeal area and shorter facial fovea. Male facial fovea surrounded by yellow; mesosoma except propodeum yellow ventrally and laterally. Distinguished from E. kubinensis   and E. carnarvonensis   by relatively long facial foveae and absence of stiff mandibular setae.

Description. Female.—Head width 0.85 mm, body length 3.0 mm. Relative measurements: HW 50, HL 41, UID 33, LID 27, FVL 11, CW 24, CL 9, FL 25. Head and mesosoma dark metallic green-bronze except propodeum black and the following yellow: clypeus, supraclypeal area, lower paraocular area, lower gena, mandibles, labrum, scape and flagellum ventrally, pronotal tubercle, alar sclerites and legs (with brown marks on hind coxa and tibia). The yellow in the paraocular area extends as a finger along inner orbit to top of antennal socket. Scape and flagellum dorsally brown. Clypeus and supraclypeal area weakly tessellate with open medium punctures; frons strongly tessellate with close to dense, fine punctures. Fore basitarsal setae straight, setae on ta2–4, apically hooked ( Fig. 2d). Scutum strongly tessellate with dense fine punctures. Metasoma dark brown, apical margins T2–5 with translucent band, wider laterally, sterna with a similar translucent margin preceded by a pale yellow band. The widths of the yellow bands vary between specimens.

Male.—Head width 0.88 mm, body length 2.5 mm. Relative measurements: HW 50, HL 41, UID 33, LID 27, FVL 9, CW 23, CL 9, FL 29. Head yellow except vertex and occiput black with a dark green metallic sheen; fovea surrounded by yellow. Mesosoma   and metasoma dark dorsally, yellow ventrally (except S1 brown medially); scutum and scutellum with slight metallic green sheen, anterolateral corners of scutum, pronotal tubercle, tegula and alar sclerites yellow; apicolateral margins of metasomal terga translucent, preceded by narrow yellow line. S5 with prominent fringe of white hair, short medially. Legs yellow. Sculpture as for female except scutal punctures weak.

Remarks. In some females the scutellum and metanotum are brownish.

Etymology. The specific epithet is a Latin adjective meaning bronze headed.
