( Figs. 4 F-I)

Type material. Holotype. Male , with the following data: “ Brasil, Rondônia, Pimenteiras, 5760, 19/02/97, S 12°40.194’/ W61°21.825’, Brown, Boina Vieira. ” ( INPA).

Diagnosis. Male. Paraocular stripes very short and situated at the middle, anterior midtibial tuft large and elliptic with a basal emargination, the posterior smaller and elliptic.

Description. Measurements: Total length 11 mm, length of labiomaxillary complex almost 2,5 times eye length. Morphology: Labrum subquadrate, almost as wide as long, with median keel, mandible bidentate, clypeal disc tricarinate ( Fig. 4f ), scutellum short and slightly rounded behind, corresponding less the half its width, with faint median depression, slightly convex above ( Fig. 4g ), length of labiomaxillary complex surpassing the end of metassoma ( Fig. 4h ), midtibiae with anterior tuft large and elliptic, the posterior smaller and elliptic ( Fig. 4i ), hindtibiae subtriangular and depressed posteriorly ( Fig. 4h ), SII with small, widely separated tufts. Color: Clypeal disc, part of front and upper paraocular areas blue, supraclypeal green, labrum with two black spots, black also in the distal margin, ivory paraocular stripes short and thiny, forward side of the antennal scape black ( Fig. 4f ), head, torax, legs, and metassoma metallic green ( Fig. 4g,h ). Pilosity: Face black mixed with white, gena, legs, and sterna white, vertex, pronotal lobes, scutum, and scutellum black. Punctation: Clypeal disc dense, medium to large, lower paraocular areas less dense and superficial, near ocelli strongly dense, irregular, and medium to large punctures ( Fig. 4f ), tegulae and mesoscutum less dense and with small punctures, scutellum sparse and with micropunctures to large, mesepisternum very dense with medium-sized and deep punctures, external face of hindtibiae less dense to sparse, with small to medium punctures posteriorly, TI-IV very dense and with micropunctures, V-VII very dense, beveled, large, and irregular.

Female. Unknown.

Geographic records. BRAZIL: Rondônia.

Etymology. A reference to the short paraocular stripes.

Bait. Unknown.

Comments. It belongs to the Euglossa (Euglossa) purpurea species-group for sharing with it the features as mentioned above by Dressler (1978), except the hindtibiae subtriangular. On the other hand, it is similar to three species of the Euglossa (Euglossa) cordata species-group: Eg. gaianii Dressler, 1982 and Eg. variabilis Friese, 1899 due to the short paraocular strips, and to Eg. ioprosopa Dressler, 1982 due to the labrum with two dark brown spots. But differing them by the anterior midtibial tuft smaller.
