V. 2023; D. Díaz | M. S. Basantes | E. Marcayata leg.; bottle trap Vainillin. Identification. Within the macroglossa group, the species Euf. macroglossa can be distinguished by the steel blue male face and purple female face, male midtibial brush continuous with an anterior felty patch, and gonostylar dorsal lobe as long as the ventral one. Among the most similar species, the colour of the terga distinguishes them: Euf. venusta generally has brilliantly orange to coppery terga, Euf. lucida has more greenish terga, Euf. macroglossa has reddish / yellowish terga, and Euf. nigrescens has dark purplish terga (Kimsey, 1982).	en	Hernández Hernández, Alexandra D., de Oliveira, Marcio L., Diaz-Guevara, David R., Alarcón-Ortiz, Cristina, Pazmiño-Palomino, Alex (2025): First records of four orchid bee species (Hymenoptera, Apidae: Euglossini) in Ecuador.
