Figure 7 in Characterization of the orchid bee Euglossa viridissima (Apidae: Euglossini) and a novel cryptic sibling species, by morphological, chemical, and genetic characters
Figure 7. Geographical distribution of tridentate Euglossa dilemma sp. nov. (black) and predominantly bidentate Euglossa viridissima (white) as inferred from recent baiting assays (circles) as well as museum material (diamonds). Note lack of E. viridissima in the south-eastern part (Costa Rica) of the range. Museum material included paratypes of E. dilemma and additional specimens of one or both species in the collections of D. W. Roubik, T. Eltz (CTE), G. Gerlach (CGG), the Zoologische Staatssammlung München (ZSM), the Smithsonian Institution (SI), and the Snow Entomological Collection (SEC). Only unambiguous and non-redundant localities were plotted. Localities of baiting assays are (from west to east): Chamela (Jalisco, Mexico), El Chote (Veracruz, Mexico), Ayozinthepec (Oaxaca, Mexico), Monte Pio and Poza Azul (both Veracruz, Mexico), Tuxtla Gutiérrez, Esquintla, Tapachula, Ocosingo and Palenque (all Chiapas, Mexico), Atasta (Campeche, Mexico), Retalhuleu (Guatemala), Lacanjá (Chiapas, Mexico), Escarcega (Campeche, Mexico), El Remate (Campeche, Mexico), Chablekal, Xmatkuil (Yucatán, Mexico), Tikal (Guatemala), San Crisanto (Yucatán, Mexico), Chetumal and Coba (both Quintana Roo, Mexico), Chinandega, Chacocente, Escameca Grande, Jinotega, Ometepe and Las Pampas (all Nicaragua), and Area de Conservación Guanacaste (Costa Rica).
Figure 6 in Characterization of the orchid bee Euglossa viridissima (Apidae: Euglossini) and a novel cryptic sibling species, by morphological, chemical, and genetic characters
Figure 6. Chronogram showing divergence times and phylogenetic relationships of selected lineages in the genus Euglossa and the sibling species Euglossa dilemma sp. nov. and E. viridissima. The tree topology corresponds to that obtained via Bayesian methods. Bayesian posterior probabilities and parsimony bootstrap values are shown for the sister species only. Divergence times were obtained via penalized likelihood using the fossil-calibrated molecular clock procedures described in Ramírez et al. (2010b). The maximum and minimum age estimates for the MRCA of E. dilemma and E. viridissima correspond to the molecular clock analyses in which the MRCA of the genus Euglossa was assigned a fossil calibration of 20 and 15 Myr, respectively.
Figure 2 in Characterization of the orchid bee Euglossa viridissima (Apidae: Euglossini) and a novel cryptic sibling species, by morphological, chemical, and genetic characters
Figure 2. Allele size distribution of Euglossa viridissima- like males from the Yucatán peninsula, Mexico, at the microsatellite locus ann02. Overall, bidentate males (grey bars) had significantly smaller allele sizes than tridentate individuals (black bars), and there was little overlap in allele size. The seven individuals indicated as red circles were also tridentate, but had been clustered with bidentate males in the analysis of perfume similarity (see Fig. 1), lacking HNDB. These seven individuals had the third (central) mandibular tooth significantly displaced towards the tip of the mandible (nearer to the distal tooth, see Fig. 3B), unlike in other tridentate males. Their ann02 allele size suggests that they in fact belong to the bidentate lineage. See text for further explanation.
Figure 4 in Characterization of the orchid bee Euglossa viridissima (Apidae: Euglossini) and a novel cryptic sibling species, by morphological, chemical, and genetic characters
Figure 4. Results of a PCA of 15 morphological variables measured in male Euglossa viridissima and Euglossa dilemma sp. nov. Components 1 and 3, which showed significant differences between the species, are used for this two-dimensional representation. Note that E. dilemma shows slightly less variability and is essentially nested within E. viridissima morphospace. Centroids of distributions are shown.

Figure 3. A, Euglossa viridissima-like males attracted to a bait dish at Xmatkuil, Yucatán, Mexico. B, mandibular morphology of males of tridentate Euglossa dilemma sp. nov., and tridentate and bidentate males of E. viridissima. The position of the central mandibular tooth in tridentate individuals is expressed as the ratio of the distance between the distal and the central tooth to the distance between the central and the basal tooth. Means and standard deviations are given.

BL, Body length; HW, Head width; ID, Intertegular distance;WTII,Width of colored bands on tergum II; WTIII,Width of colored bands on tergum III. In this phyloheatmap, each column of the measured characters was standardized to have the same variance prior to analysis.The scale below indicates how much each value deviates from the mean.The colors of the clades correspond to geographic regions outlined in Fig. 1.

Fig. 2 in Phylogenomics reveals within species diversification but incongruence with color phenotypes in widespread orchid bees (Hymenoptera: Apidae: Euglossini)
Fig. 2. Phylogenetic relationships of the E. meriana and E. bombiformis species complexes based on (A) mitochondrial data (mtDNA; CO1 and Cytb) and (B) ultraconserved elements (UCE; 2022 loci). The mtDNA phylogeny was estimated using Bayesian inference in BEAST2, posterior probabilities on nodes were all above 0.9 except for nodes with asterisks (*).

Support values on nodes indicate ultrafast bootstrap (UFB) and SH-like (SH) approximate likelihood ratio test scores (SH-aLRT). All support values were above 95/95 except for nodes indicated with asterisks (* or **). One of the E. cingulata individuals (TA12) was pruned to improve the cophylogenetic visualization.The colors of the clades correspond to geographic regions outlined in Fig. 1. Green: Central America, Orange: Choco region, Blue: Amazon Forest, and Pink: Atlantic Forest.
