## 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 1Aglae, 23Eufriesea, 68Euglossa, 18Eulaema, and 5Exaerete,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.

## 1. Introduction

Orchid bees are a conspicuous and a fascinating group of Neotropical bees, in which males have noteworthy behavior related to gathering aromatic compounds from orchids and other sources [1]. The bees increasingly are objects of study in different fields such as ecology [2, 3], chemical ecology [4–8], conservation [9–11], evolution [12], and taxonomy [13–17]. Such research contributes to an understanding of general bee biology and how neotropical ecosystems function.More than 252 species have been described, and many synonymized, since early descriptions by Linneaus (1758) under the genus nameApis [18]. Several species lists have been published at regional levels [18–21] and the country level, Brazil [19, 21–28], Peru [19, 29, 30], Panama [19, 31, 32], Bolivia [33], Colombia [19, 34], Mexico [35], Nicaragua [36], Honduras [37], and Venezuela [19].Ecuador is well known as a megadiverse country with an outstanding diversity of organisms and ecosystems and considered important for conservation proposes, e.g., the Tumbes-Choco-Magdalena region and the tropical Andes [38, 39]. At the same time, from the species records examined here and from biogeographic analyses of other apidologists, e.g., [13, 40], it is clear that the NW of Ecuador is quite similar to Central America, while Amazonian Eastern Ecuador and the Andes have some different species. Additionally, among the well-studied Ecuadorian palms, although most species are Andean compared to other regions, 60% of them are from adjacent lowlands; i.e., they are not Andean endemics [41].Here we update the taxonomic base of knowledge on Ecuadorian euglossines. Only two publications had reported, in general, species for Ecuador. Ramírez et al. [19] report 62 species and Moure et al. [18] report 63. Recent articles treat the taxonomy of the orchid bees of Ecuador, mainly focusing on the description of new species,Euglossa samperi [42];Euglossa natesi [43];Euglossa williamsi [44],Euglossa celiae, andEuglossa subandina[45]. As part of our continuing study of euglossines in Ecuador and elsewhere, while not listing unnamed species here (as for Meliponini, see [46], or Euglossini, [47]) we attempt to bring euglossine taxonomy up to date, particularly in western South America, and include limited discussion of taxonomic problems.


## 2. Methods

### 2.1. Material Examined

All material examined from museums came from the following institutions:INABIO: Instituto Nacional de Biodiversidad, Quito-Ecuador.
MZUA: Museo de Zoología de la Universidad del Azuay, Cuenca- Ecuador.
NMNH: National Museum of Natural History, Smithsonian Institution, Washington DC - USA.
QCAZ: Museo de Zoología de la Pontificia Universidad Católica del Ecuador, Quito-Ecuador.
STRI: Smithsonian Tropical Research Institute (DW Roubik collection), Balboa, Panama.Additional data came from the following institutions:AMNH: Amercian Museum of Natural History, New York, USA.
DZUP: Departamento de Zoología, Universidad Federal do Paraná, Curitiba, Brasil.
FLMNH: Florida Museum of Natural history, Gainesville, USA.
ZSM: Zoologische Staatssammlung Munchen, Munchen, Germany.


### 2.2. Field Work

Several locations in the country had been visited in most of the provinces of Ecuador during the last decades, mainly by DW Roubik and also by PS Padrón and RB Picón (Figure1). Orchid bees were collected in bait traps or collected using hand nets at baiting stations, using chemical attractants such as cineole, eugenol, skatole, vanillin, PDMB (p-dimethoxybenzene), methyl salicylate, and methyl cinnamate, during the day at different periods between 08,00 and 17,00 h.Figure 1
Species richness pattern observed for the Euglossini tribe in Ecuador based in 2332 collecting records.The species list is presented by subgenus and species following the systematic arrangement proposed by Moure et al. [18], so it does not include the recently named subgenus ofEuglossa, Alloglossura, which will be subject to further evaluation [17], nor a proposed nameHybomelissafor theExaeretegroup containingE. frontalis [48]. The species determinations were based upon comparative study of type and other material at NMNH and in the collections of DW Roubik and RL Dressler, at STRI and at the Florida Museum of Natural History, particularly collections made by DW Roubik from French Guiana, Panama, Costa Rica,l and Ecuador. Diagnostic reference photographs also were consulted for euglossines of French Guiana (Discover Life, https://www.discoverlife.org/mp/20p?see=I_DWR, and the NMNH euglossine types, https://biogeodb.stri.si.edu/bioinformatics/roubik_bees/). We attempt to treat determinations made by others as likely correct, unless we had additional information, and acknowledge that some of the above cited reference material, or identifications, may be erroneous.


### 2.3. Species Richness

A total of 2322 distribution records were georeferenced, localities were plotted using DIVA-GIS 7.5 [49], and the species richness was calculated.

## 4. Discussion

With 115 species reported for Ecuador, our results almost double the number known from previous work [19] (62) and [18] (63 species). In a medium elevation area of north central Peru [81] there may be similar species richness, but as we suggest below, the highest species diversity occurs, as in many groups, in NE Ecuador.In Ecuador, the genusEuglossa is the most diverse, with 68 species, followed byEufriesea 23,Eulaema18,Exaerete 5, andAglae 1 species. Fifty-two new species records are added for the country, compared to the most recent species list, in [18]. The new species records are distributed in four genera. Thirty-nine new species records are added for the genusEuglossa, 4 new species records forEulaema, 9 new species records forEufriesea,and 2 new species records forExaerete (Table 1). There are at least 10 more undescribed species.Table 1

lepeletieriOliveira & Nemésio, 2003Finally, for the monotypic genusAglae, here we added new distribution records for its conspicuous speciesA. coerulea Lepeletier & Seville, 1825, in Napo, Pastaza, and Esmeraldas Provinces, extending its known distribution to the Eastern Andes in Ecuador. Previously it was reported for Ecuador by [50] from the Chocó Region in western Ecuador.Our results show a clear richness pattern (Figure1), with a concentration of species in the Amazon region. As noted by previous authors [13, 19, 40, 66] the northwest is similar to Mesoamerica and Panama. The Andean and inter-Andean region, between the Cordillera Occidental and Oriental, may hold endemic euglossines, but the overall similarity to Peru and Colombia does not permit such a view at present. The lower to medium elevation Andes region may, like the palms [41], hold the most species. For now, most Ecuadorian euglossines have been found east of the Andes, in the lowlands. This is perhaps the result of more intensive sampling there, especially at the Estación Biológica Yasuní. It is also clear that some areas are poorly sampled, especially the southern part of Ecuador. In those areas, such as the Cordillera del Condor, Cerro Plateado, Zapotillo, and Zumba Regions, more new species records for the country will likely be found, as is now the case in Yasuní forest, in the northeast.Any single reported collection should, for the time being, be viewed with some skepticism and needing replication and confirmation. The single recorded specimens that differ from the gender of the designated holotype, for example, the male ofEufriesea combinata orEufriesea theresiae [51], require further field work to validate. We see a need to emphasize that some species are quite difficult to identify and distinguish, likely due to mimicry, and phylogenetically close relatives that first separated by climate changes during glaciations, either on both sides of the Andes or in higher elevation areas, compared to lowlands. There are reasonably cryptic sibling or close relatives. For example,Euglossa chalybeata andE. piliventris, previously thought to be native to Ecuador, have yet to be found there, but in their placeEuglossa orellana, E. occidentalis, andE. lugubriswere described [65]. Similarly, Kimsey [13] pointed out the synonymy ofEufriesea andina with its senior synonym,Ef. magrettii, and the color polymorphism of the males in both this species andEf. venezolana, which had confused previous taxonomic work. We find also very slight differentiation between twoEulaema and subgenusApeulaema, although some of the reported males in Ecuador may in fact match those of French Guiana—the type area forEulaema cingulata—and we have examined two from Eastern Ecuador that are different, one indistinguishable externally fromEulaema of Panama, which is now tentatively given the nameEulaema marcii, but which was described from Eastern Brazil. Further study of genitalic details would repay the effort.
