Figs 3c, 5c, 12, 26, 34

Type specimens. HOLOTYPE ♂, 15 km W of Windorah, Queensland, 24 Sep 1983, S. R. Monteith , on Eucalyptus terminalis in QM ( T234986 ) . PARATYPES (10♀♀, 3♂♂, all in QM), same data as holotype ( QM T234987–999 ) .

Diagnosis. Female with head and mesosoma predominantly yellow, very like E. flava , but facial profile more strongly curved ( Fig. 5). Male head entirely yellow, mandible inflexed apically with stout setae on ventral edge. Distinguished from E. flava and E. pallida by form of mandible and terminalia.

Description. Female.—Head width 1.05 mm, body length 3.0 mm. Relative measurements: HW 50, HL 40, UID 29, LID 27, FVL 10, CW 24, CL 9, FL 24. Head yellow except occiput black, flagellum brown dorsally. Frons and scutum dull, weakly tessellate with dense punctures. Mesosoma yellow with irregular brown marks on scutum. Dorsal and posterior faces of propodeum and most suture lines black. Metasoma yellow with dorsum black medially.

Male.—Head width 1.09 mm, body length 3.4 mm. Relative measurements: HW 50, HL 38, UID 30, LID 27, FVL 7, CW 24, CL 8, FL 24. Colour as for female except flagellum entirely yellow. Mandible with apical ⅓ inflexed, 3 or 4 stout setae at point of inflection ( Fig. 3c). S5 with prominent fringe of white hair, longer laterally. Sculpture as for female but finer making the surface almost matt.

Etymology. The specific name refers to the relatively broad head of this species.
