( Figs. 2 View Figure 2 E-H)

Type material. Holotype. Male with the following data “ Caruaru, PE, Brejo dos Cavalos, Brasil, [36W 00’ 00”/8S 18’ 37”], 17.2.2000, D. Schiffler leg, 1275 UFPE, p 4, Scatol L 114” ( INPA) . Paratype, male, idem, except the number 1267 ( INPA) .

Diagnosis. Male. Anterior midtibial tuft small and similar to a simple quotation mark (‘), the posterior smaller and subcircular, scape black, ivory paraocular stripes absent, scutellum depressed posteriorly.

Description. Measurements: Total length 11 mm, length of labiomaxillary complex near 2.5 times eye length. Morphology: Length of labiomaxillary complex reaching the end of metassoma ( Fig. 2g View Figure 2 ), mandible bidentate, labrum subquadrate, wider than long, with median keel, clypeal disc tricarinate, scutellum relatively rounded behind, depressed posteriorly, less than half as long as wide, with a faint median depression, midtibiae with anterior tuft small and similar a simple quotation mark (‘), the posterior smaller and subcircular, hind tibia subtriangular, SII with small, widely separated tufts. Color: Scape black, ivory paraocular stripes absent ( Fig. 2e View Figure 2 ), face, mesoscutum, and tegulae metallic green with blue and golden reflections, gena, pronotal lobes, meso- and metepisternum, and hindtibiae metallic green with golden reflections, TI-IV metallic green, V-VI metallic green with golden reflections ( Figs. 2 View Figure 2 f-g).

Female. Unknown.

Geographic records. BRAZIL: Pernambuco.

Etymology. A reference to Caruaru, the municipality where the specimen was collected.

Comments. This species also belongs to the Eg. purpurea species-group for sharing with it the features defined above by Dressler (1978). The anterior midtibial tuft resembles Eg. laevicincta Dressler, 1982 and the face without ivory strips to Eg. viridifrons Dressler, 1982 but both belong to the subgenera Glossurella. Apparently, this species is endemic to the place called Brejo dos Cavalos. “Brejo” is a local name for high-altitude vegetational formations separate from the Atlantic Forest, which occur in Ceará, ParaÍba, and Pernambuco and states in Northeast of Brazil, as islands of humidity in the Caatinga (a semi-arid vegetational formation).
