Diagnosis. Female mostly black, clypeus with yellowbrown suffusions, legs mostly yellow, face not elongate. Distinguished from E. incisa by convergent inner orbits and yellow femora. Male face yellow to ocelli and scutum yellow with large U-shaped black mark ( Fig. 9).

Description. Female.—Head width 0.97 mm, body length 3.1 mm. Relative measurements: HW 50, HL 40, UID 31, LID 24, FVL 8, CW 23, CL 10, FL 26. Head black except clypeus ventrally and mandibles yellow-brown, clypeus basally and supraclypeal area dark brown; antenna ventrally dull yellow, dorsally brown. Fore basitarsal setae stiff, capitate; setae on ta2–4 bent 90°. Frons weakly tessellate with open punctures. Mesosoma black with following yellow: tegula, alar sclerites and legs (with brown infuscation of hind coxa). Scutum moderately strongly tessellate with close punctures. Metasoma black dorsally with lateral margins T2–4, apical margin T5 and all T6 yellow, ventrally yellow (except S1 brown).

Male.—Head width 0.88 mm, body length 2.7 mm. Relative measurements: HW 50, HL 40, UID 33, LID 25, FVL 4, CW 21, CL 9, FL 31. Head yellow except vertex and adjacent area of occiput black. Mandible with ca 3 stiff setae on ventral margin ( Fig. 3d). Frons strongly tessellate with open to close punctures. Mesosoma yellow with following black: U-shaped mark on scutum, dorsal surface of propodeum, some or all of metanotum, subalar pits and some suture lines. Scutum strongly tessellate with dense punctures. Metasoma yellow ventrally, dorsally black, except apicolateral corners of T1–5 and all T6 yellow. S5 with prominent fringe of white hair, short medially.

Remarks. Some females have the dorsal surface of the metasoma entirely dark brown or black, while sterna may have brown infusions. The amount of yellow on the metasoma of males is also somewhat variable.

Etymology. The specific name refers to the flower from which the species has most frequently been collected.
