( Figs. 3 View Figure 3 A-D)

Type material. Holotype. Male , with the following data: “ Brasil, Roraima, P. [arque] N. [acional] Monte Roraima, Aldeia KaramambataÍ, c. 1000 m.a., 28 nov-08 dez 2019, 05°07.41’N / 60°35.90W, M.L. Oliveira, F. Xavier F. & S. Lima, isca de cheiro, mata” ( INPA) GoogleMaps . Paratypes, 3 males with the same data ( INPA) GoogleMaps .

Diagnosis. Male. Clypeal disc and frons blue, ivory paraocular stripes incomplete below, straight, and fine, forward side of antennal scape with a small ivory spot, terga I-III and central part of external face of hindtibiae coppery.

Description. Measurements: Total length 10 mm, length of labiomaxillary complex near two times eye length. Morphology: Labrum subquadrate, almost as wide as long, with median keel, clypeal disc tricarinate ( Fig. 3a View Figure 3 ), mandible bidentate, length of labiomaxillary complex reaching the end of metassoma ( Fig. 3c View Figure 3 ), scutellum short and straight behind, corresponding less the half its width, without median depression, slightly flat above ( Fig. 3b View Figure 3 ), anterior midtibial tuft bilobed, the upper lobe large, the lower smaller, posterior tuft elliptic ( Fig. 3d View Figure 3 ), hindtibiae subtriangular and inflated ( Fig. 5c View Figure 5 ). Color: Clypeal disc and frons blue, ivory paraocular stripes incomplete, fine and straight, forward side of the antennal scape with a small ivory spot ( Fig. 3a View Figure 3 ), central part of external face of hindtibiae coppery, terga I-III copper, rest of body metallic green ( Figs. 3 View Figure 3 b-c). Pilosity: Vertex, mesoscutum, scutellum, pronotal lobes, and metepisternum black mixed with white; face, gena, mesepisternum, legs, and terga white. Punctation: Clypeal disc dense, irregular, and small to large, lower paraocular areas sparse, large, beveled, and superficial, supraclypeal area very dense, irregular, large, and beveled, near ocelli very dense, small, and coalescent ( Fig. 3a View Figure 3 ), tegulae and mesoscutum very dense and small, scutellum less dense and small to large, mesepisternum very dense, large, and coalescent, external face of hindtibiae dense to less dense, large, and beveled, TI-IV very dense and with micropunctures, V-VI very dense, beveled, large, and irregular, VII less dense, small, and medium.

Female. Unknown.

Geographic records. BRAZIL: Roraima state.

Etymology. A reference to the copper coloration of hindtibiae and metassoma.

Bait. Unknown.

Comments. Also belonging to the Eg. purpurea species-group for sharing with it the features defined above by Dressler (1978). In general, similar to Eg. avicula and Eg. pleosticta Dressler, 1982 due to the midtibial tufts but differing from the first by the metassoma copper and from the second by the length of labiomaxillary complex longer, the ivory paraocular stripes incomplete, fine and straight, and the forward side of the antennal scape with a small ivory spot. Similar also to Eg. aeneolusa sp. nov. but it has all terga copper and not just the II-VII.
