- Euglossa (Dasystilbe) Dressler, 1978: 193. Type species: Euglossa villosa Moure, 1968, by original designation.
Diagnosis
Large bees (body length nearly 15 mm), body coloration bright metallic green with either bronzy or blue iridescence and noticeable differently-colored apical bands on first four metasomal terga (Figs 1–3); body covered with noticeable long dense fulvous setae especially on lateral and ventral sides; upper and lower interorbital distances equal; clypeus not noticeably protuberant (no more than 0.90 mm); labrum rectangular, wider than long; male mandible bidentate, female mandible tridentate; labiomaxillary complex in repose reaching at most posterior margin of second metasomal sternum; pronotal dorsolateral angle projected laterally as an acute prong (Fig. 10); posterior border of mesoscutellum semi-ellipsoidal, female with a large dark mesoscutellar patch (Fig. 3); male mesotibia with two setose patches, anterior one large, ellipsoidal, occupying nearly one-third of mesotibial length, posterior one ovoid-oblong about one-third as long as anterior patch (Figs 15–16); microtrichia of velvety area on male mesotibia becoming sparser anteriorly (Figs 15–16); inner surface of male mesobasitarsus with a prominent distal elevation obliquely ridged (Fig. 11); second mesotarsomere of male with basal emarginations on both anterior and posterior margins (this may sometimes be obscured by expansion of the inner surface); male metatibia triangular with no evident furrow on posterodorsal margin; metatibial organ slit not reaching ventral margin of male metatibia, but separated from it by less than its own length (Figs 19–20); male metabasitarsus lanceolate, anterior margin conspicuously convex especially on proximal section (Fig. 12); metafemur of male with ventral margin strongly concave especially as seen on inner surface (Fig. 14); male second metasomal sternum with two cowled slits [sensu Roubik (2004)[1]] posteriorly narrowed and separated by about one and a half times width of an individual slit (Fig. 13); eighth metasomal sternum with noticeable lobes on lateral margins (Fig. 22), with posterior section of eighth metasomal sternum laterally about as wide as lateral width of anterior section (Fig. 23); dorsal process of gonocoxite noticeably longer than wide; lateral section of gonostylus with concave inner setose area covered by long simple setae (Figs 24–26).
