Type specimens. HOLOTYPE ♂, 19 km S Charleville , Queensland, 26.565°S 146.200°E, M. Batley, 6 Sep 2013, ex Calytrix longiflora   in AM ( K447281) GoogleMaps   . PARATYPES (23♀♀, 17♂♂, all in AM), same data as holotype GoogleMaps   . (K447247–280, K470067–072).

Diagnosis. Female mostly black, clypeus with yellowbrown suffusions, head elongate. Distinguished from E. carnarvonensis   by length of facial fovea and large part of femora brown. Male with elongate head, yellow to top of fovea; S5 with two pairs of distinctive setae unlike any other species.

Description. Female.—Head width 0.9 mm, body length 3.25 mm. Relative measurements: HW 50, HL 48, UID 31, LID 23, FVL 13, CW 22, CL 9, FL 27. Head black with clypeus, supraclypeal area and lower gena brown, mandible and labrum yellow-brown.Antenna yellow ventrally, dark brown dorsally. Labrum without an apical spine. Frons tessellate with sparse, fine punctures. Mesosoma   black with pronotal tubercle, tegula, alar sclerites and legs yellow (with the following brown: coxae, trochanters medially, femora other than distal end, small brown patch on hind tibia and all distitarsi). Hind basitibial area defined by carinae only basally. Scutum tessellate with dense punctures. Metasoma dark brown, T1–5 with translucent apical margins, T6 pale yellow apically, pygidial plate amber; sterna lighter with irregular yellow-brown markings. Occasionally metasoma entirely black.

Male.—Head width 0.85 mm, body length 2.7 mm. Relative measurements: HW 50, HL 46, UID 31, LID 24, FVL 8, CW 21, CL 10, FL 36. Head yellow with vertex, occiput and frons down to top of fovea black. Frons strongly tessellate obscuring any punctures. Mesosoma   black with the following yellow: pronotum, lateral margins of scutum to rear of tegula, ventral half of mesepisternum except for a medial black patch. Scutum strongly tessellate with dense punctures. Metasoma dark brown dorsally (except apical tergal margins translucent), apical half of T6 and venter yellow. S6 weakly concave, fringe on S5 reduced to sparse row of very long, plumose setae, including a pair of broad pinnate setae on each side. Metasomal S2–S5 have slightly elevated areas either side of midline ( Fig. 6).

Etymology. The specific name is a Latin adjective referring to the feather-like setae on the fifth sternum of the male.
