A Preliminary Checklist of the Orchid Bees (Hymenoptera: Apidae: Euglossini) of Ecuador

Abstract

A checklist of Euglossini in Ecuador is given, including all currently described, valid species collected until 2018. The list has been assembled from museum records, fieldwork cited herein, and literature. The former species lists are nearly doubled here, with 1 Aglae, 23 Eufriesea, 68 Euglossa, 18 Eulaema, and 5 Exaerete, 115 in total with >50 new records for the country. Distribution and collection data are included, and some doubtful species are discussed. The Amazon region is the most species rich area but not necessarily a natural pattern, perhaps due to uneven sampling effort across the country. Southern Ecuador is relatively little sampled.

Population Traits and a Female Perspective forAglaeandExaerete, Tropical Bee Parasites (Hymenoptera, Apinae: Euglossini)

“…comm. ), then it can certainly be added to the parasitic bee fauna of the Amazonian Yasuní Biosphere Reserve, which, like many organisms, contains the highest diversity known anywhere [19,20]. It is by any standard a rare bee.…”

First Case of Gynandromorphism in the Orchid-Bee Eulaema meriana (Olivier) (Hymenoptera: Apidae)

“…This is due to the notable lack of knowledge of the Ecuadorian bee fauna. Although, in recent years, euglossines have been the relatively most studied group of this fauna, to the point that they are the only group that currently has a species checklist and several recent revisions (Botsch et al, 2017;Padrón et al, 2018;López, 2018;Yanouch et al, 2018;Suárez-Torres, 2019;Roubik, 2019).…”

New and old records of Euglossa imperialis Cockerell, 1922 (Apidae, Apinae, Euglossini) for the Amazon rainforest, Cerrado, and Pantanal of Mato Grosso, Brazil

“…With vast geographical distribution throughout the Neotropics, E. imperialis has been recorded from southern Mexico, and possibly Jamaica (Roubik 2004), to the Amazon forest and Cerrado domains in mid-west Brazil, the fragmented areas of the Cerrado, and the Atlantic forest in southern Brazil (Rebêlo and Moure 1995;Oliveira and Campos 1996;Rebêlo and Garófalo 1997;Silva and Rebêlo 1999;Roubik 2004;Anjos-Silva 2006a, 2006b, 2011Moure et al 2012;Figueiredo et al 2015;McCravy et al 2016;Antonini et al 2017;Tosta et al 2017;Cândido et al 2018;Coswosk et al 2018;Henrique et al 2018;Machado et al 2018;Padrón et al 2018).…”

“…Euglossa imperialis presents a large range of geographic distribution and has been reported from southern México (Chiapas, Quintana Roo, Veracruz) to Honduras (McCravy et al 2016), Costa Rica, Nicaragua, Panama, Colombia, Ecuador, and Peru (Janzen et al 1982;Ackerman 1983;Zimmerman and Madriñan 1988;Roubik 1993;Eltz et al 1999;Otero and Sandino 2003;Roubik 2004;Roubik and Hanson 2004;Moure et al 2012;Hinojosa-Díaz and Engel 2012b;Padrón et al 2018). It has also been catalogued from Brazil (Moure 1989;Becker et al 1991;Rebêlo and Garófalo 1991;Rebêlo 1993;Rebêlo and Moure 1995;Rebêlo and Silva 1999;Nemésio and Faria Junior 2004;Darrault et al 2005;Anjos-Silva 2006a, 2006b, 2011Faria Junior and Melo 2007;Oliveira et al 2010;Schorn de Souza 2014;Figueiredo et al 2015;Mateus et al 2015;Oliveira-Junior et al 2015;Antonini et al 2017;Tosta et al 2017;Cândido et al 2018;Henrique et al 2018;Coswosk et al 2018;Machado et al 2018).…”
