Both sexes of this species are most similar to E. coerulescens , from which it can be separated easily by the longer glossa and more densely punctate disc of T2. The female of E. oliveri can be recognized from that of E. barthelli by the mesoscutellum coarsely and non-contiguously punctate submedially, with a weak medial groove lacking a distinct row of setae (finely, contiguously punctate with stronger medial groove having a distinct row of setae in E. barthelli ), and by the T2, which is more densely punctate on disc, with punctures separate by at most a puncture width (punctures separated by 1.0-2.0 times a puncture width in E. barthelli ).


Holotype, ♂: As described for E. coerulescens except as follows: Head width 5.7 mm; intertegular distance 4.6 mm; body length 15.4 mm; forewing length 13.5 mm. Glossa in repose reaching S2; metabasitarsus with posterodistal margin more rounded, not as acute as in E. coerulescens . Hidden sterna and genitalia as in Figs 58-62 View Figures 58–62 .

Vertex and gena green with weak blue and purple hues. Mesosoma (excluding legs) predominantly green except mesoscutellum green with weak blue and golden hues; metatibia basally mostly green with golden hues; wing membrane infuscate, lighter than in E. coerulescens . Metasoma green with distal margins of terga and sterna (excluding S2) weakly blue to purple.

Head with whitish setae, with scattered gray to black setae on vertex. Mesotibia with area between medial margin of posterior patch and anterior margin of tibia setose on basal half, distal half asetose; posterior patch 5.7 times longer than broad, subapically narrower than distance between its medial margin and anterior margin of tibia.

T2 with punctures on disc separated by at most half a puncture width, impunctate distal margin very narrow, at most as wide as a puncture width.

♀: Head width 6.3 mm; intertegular distance 4.9 mm; body length 18.4 mm; forewing length 13.5 mm. Metatibia with emargination on distal margin about half width of posterodistal angle; metabasitarsus twice as long as broad.

Blue with purple hues on mandible basally, labrum, frons, vertex, gena, dorsum of mesosoma, mesepisternum, propodeum, legs, discs of sterna, and marginal zones of terga.

Pubescence black, except off-white on sides of T2, T3-T6, sides of S2 and S3, entire S4 and S5, and S2 basally. Mesoscutellum without row of dense setae on weak medial longitudinal groove.

Clypeus with median longitudinal ridge continuing onto supraclypeal area; labrum with distinct median and sublateral carinae. Mesoscutellum with coarse, non-contiguous punctures submedially. T2 with punctures sparser than in the male, separated by a puncture width or less.

Floral records.

Females have been collected on flowers of Cassia sp. ( Fabaceae ). Males have been collected on Clowesia glaucoglossa (Rchb.f.) Dodson, C. thylaciochila (Lem.) Dodson, and Stanhopea hernandezii (Kunth) Schltr. ( Orchidaceae ).


The two female paratypes as well as some female specimens from Morelos and Oaxaca have a distinctly large impunctate area just anterior to the median ocellus, but in specimens from Jalisco and Puebla this area is very reduced to nearly absent. Also, in some female specimens from these two states and Oaxaca, the punctures on the disc of T2 are sparser (1.0-2.0 times a puncture width) than in the female paratypes, and the sublateral carinae of the labrum are weak.
