Euglossa obrima Hinojosa-Diaz, Melo & Engel, 2011
Bees with a rather stocky habitus, both sexes with body coloration bright metallic green, with faint bronzy hue and blue iridescence, posterior section of first four metasomal terga with noticeable cyan-blue iridescence forming a band along tergal margins; punctation moderately dense; body with dense, fulvous, long setae especially on lateral and ventral sides of head and mesosoma; female with conspicuous ellipsoidal setal patch on mesoscutellum made of dense, dark setae; male with mesotibial anterior tuft ellipsoidal with a diagonally truncate base and a distal rounded margin, posterior tuft round, oblong partially lying on posterior half of truncate margin of anterior tuft, velvety area noticeably sparser along anterior mesotibial margin; mesotarsomeres beyond mesobasitarsus longer than wide, especially second mesotarsomere; distal section of metatibial organ slit lanceolate (spur-like), slender (maximum width occupying about one-fifth of metatibial outer surface width); second metasomal sternum with two narrow cowled slits.
Known from as far south as Nicaragua, and as north as the central Mexican state of San Luis Potosí. Euglossa obrima is found in humid environments with specimens collected in lowland areas with tropical rain forest (Chimalapas, Oaxaca, Mexico), or at mid altitudes (as high as 1600 m) in cloud mountain forest (Tlanchinol, Hidalgo, Mexico). Although collecting records are scarce, beyond the Isthmus of Tehuantepec going north, the species is absent from the Mexican lowlands along the Pacific Ocean, with records only from the lowlands along the Gulf of Mexico. The distribution of Euglossa obrima is apparently disjunct to the known distribution of Euglossa villosa which is known only from a couple of localities in Panamá, although some specimens missing locality data, deposited in the Florida Museum of Natural History, University of Florida, USA, may be from Costa Rica (Mark Whitten, pers. comm. 2006).
