Mesoscutellum convex, hardly longer than wide (1.1 ×), irregularly deeply foveate, the foveae large, widely separated medially and closer laterally, posterior margin broadly rounded, strigose. Propodeum deeply areolate; median areola 1.37 × as long as wide, with lateral ridges converging posteriorly and meeting slightly before adpetiolar areola; lateral areola transversely carinate; prestigmatic areola densely setose, setae oriented inwards. Adscrobal area of mesopleuron densely clothed with long, suberect and whitish setae, femoral scrobe finely transversely strigose, ventral shelf of mesepisternum sparsely punctate, with adpressed long setae, interspaces between punctures smooth; epicnemial carina lamellate.

Petiole quite long, 7.12 × as long as broad, 1.58 × as long as length of Gt1 in dorsal view, and 1.2 × as long as length of gaster in dorsal view, dorsally with two, lateral and sublateral, longitudinal ridges that is vague along the apical two-thirds, the area between sublateral ridges transversely wrinkled. Gaster ovoid in dorsal view, 1.25 × as long as its height in lateral view. Gt1 long (0.75 × as long as gaster in dorsal view), deeply concave posteriorly, sparsely finely setiferous punctate (setae fine and short, punctures dense postero-laterally); remaining tergites short, sparsely finely punctate and finely setose.
Color (Figs 6A-C View Figure 6 , 8C View Figure 8 ). Body black, except the following parts, bright reddish brown: frontal lobe, malar area, a relatively broad strip around eye, gena, pronotum, a lateral longitudinal strip on middle lobe of mesoscutum, lateral and posterior borders and postero-inner corner of scapula, inner part of axilla, area around epicnemial carina on mesopleuron, upper part of metepimeron, and posterior part of adpetiolar area on metepisternum. Gaster reddish brown with black tint dorsally. Antennal scape and pedicel reddish brown, flagellum brown. Legs reddish brown, with black tint on mesofemur, ventral face of metacoxa and outer face of metafemur. Tegula glassy golden yellow. Wings hyaline with brown veins that are paler on hind wing. Genitalia pale yellow.
Female. Unknown.
Variation.
The paratype specimens differ from the holotype specimen in the predominance of red brown color on: head (except post-orbital and occipital carinae in one of the paratype specimens or a band along occipital carina, post-orbital carina and a narrow longitudinal median strip on the frons in the other paratype specimen); middle lobe of mesoscutum (except a triangular area on disc); lateral lobe of mesoscutum (except an oval area on disc); the whole axilla, mesoscutellum (except longitudinal median strip); the whole metapleuron; metacoxa and metafemur (except black tint on the former).
Remarks.
The new species is morphologically similar to E. nitidus (Schmitz) (Democratic Republic of Congo) especially the identical frontal projection; the absence of interantennal projection; similar flagellum; the presence of outstanding setae on mesosoma; similar STV, and similar petiole. But differs from it by the partly reddish head and mesosoma (entirely black in E. nitidus ); the presence of distinctive setation on different parts of mesosoma as reported above (mesosoma with regular setation in E. nitidus ); propodeum with petiolate median areola (complete in E. nitidus ); shorter and relatively stouter metacoxa (quite slender in E. nitidus ).
Etymology.
The word similis is an adjective in Latin and means similar or resembling, referring to the similarity of this species to E. nitidus .
