Euglossa adiastola Hinojosa-Díaz, Nemésio & Engel 2012

♂: Structure (all measurements in millimeters and based on the holotype). Total body length 12.81; labiomaxillary complex in repose reaching tip of metasoma or even exceeding it by 1–2 mm in some specimens (Figs 21–22). Head length 2.78, width 4.50; upper interorbital distance 2.22; lower interorbital distance 2.15; upper clypeal width 1.19; lower clypeal width 1.96; clypeal protuberance 0.81; clypeal ridges as described for Euglossa embera; labrum wider than long, length 0.96, width 1.15; medial labral ridge sharp; paramedial labral ridges blunt, oblique, running slightly beyond length of labral windows; labral windows ovoid, occupying proximal half of labrum; interocellar distance 0.44; ocellocular distance 0.59; first flagellomere slightly shorter (0.41) than second and third flagellomeres combined (0.44); length of malar area 0.19. Mandible tridentate, middle tooth well developed and differentiated from outer tooth. Pronotal dorso-lateral angle obliquely truncate, noticeably thicker than remainder of posterior pronotal marginal ridge (Fig. 28); intertegular distance 3.56; mesoscutal length 2.89; mesoscutellar length 1.26; mesoscutellum as described for Euglossa embera (Fig. 21); mesotibial length 2.15, mesotibial spur present; mesobasitarsal length 2.00, width 0.74 (as measured at proximal posterior keel), posterior keel projected in a obtuse angle; metatibial shape triangular (scalene triangular), anterior margin rather straight on outer view (Fig. 26), metatibial anterior margin length 2.96, ventral margin length 2.74, postero-dorsal margin length 4.37, maximum metatibial thickness 1.30; metatibial organ slit narrow (narrower than in Euglossa embera), basal section teardrop shaped, anteriorly acute, length 0.59, distal section spur shaped, separated from ventral margin by more than its maximum width, maximum width occupying about one-fifth of metatibial outer surface width (Fig. 26), metatibial inner surface as in Euglossa embera, metabasitarsal length 2.30, mid-width 0.81; metabasitarsal ventral margin oblique (Fig. 26). Forewing length 9.48; jugal comb with 13–14 blades; hind wing with 17–18 hamuli. Maximum metasomal width 4.67; second metasomal sternum with two depressions as described for Euglossa embera (Fig. 27). Coloration. Head as described for Euglossa embera, except as follows: golden-bronzy coloration not as strong, paraocular ivory marks reaching epistomal sulcus, ivory spot on antennal scape extended on frontal surface (covering most of it) (Fig. 23). Mesosoma uniformly bottle green with golden-bronzy hue (Figs 21–22); legs as described for Euglossa embera (Figs 22, 24–26); wings glossy hyaline with dark brown veins (Figs 21–22). Metasomal terga bottle green with golden-bronzy iridescence (accentuated on lateral areas) (Figs 21–22); sterna as in Euglossa embera. Sculpturing. In general as described for Euglossa embera, except as follows: punctation along median mesoscutal line not as sparse, although sparser than elsewhere; metatibial outer surface with denser punctation, area along ventral margin with punctures separated by one to two puncture diameters (Fig. 26). Vestiture. In general as described for Euglossa embera, except as follows: setae on meso- and metasoma, evenly fulvous, mesoscutum and mesoscutellum with a noticeable number of intermixed brown sturdy setae; anterior section of velvety area on mesotibia, sparser than in Euglossa embera, distal third of posterior margin of velvety area rather concave (Fig. 24). Terminalia. As described for Euglossa embera. ♀: Unknown.
