Examined by photographs. Distribution. Eutrecha longirostris is known only from two localities in the states of Lara and Vargas, Venezuela (Fig. 1 ). Remarks. Eutrecha longirostris was described from a single male specimen from Punta de Tarma, in the state of Vargas, Venezuela ( Maury 1982 ). That was the only record of this species for many years, until Hernandez and Colmenares (2008) recorded a second male from Barquisimeto, in the nearby state of Lara (Fig. 1 ). No other records of E. longirostris exist to date and the female of this species remains unknown. The holotype of E. longirostris is supposed to be currently deposited at the MIZA, where the MAGS collection is being taken care of. Unfortunately, we were unable to examine this specimen or the other known male. Based on the original description and photos of the holotype made available to us by a collaborator (P.A. Colmenares), it is certain that E. longirostris is closely related to E. florezi , species from which a solid morphological distinction is not possible at this moment. Villareal-Blanco et al. (2017) presented a diagnosis to separate E. florezi from E. longirostris . Nevertheless, the diagnostic characters listed by these authors are rather discretionary and it is possible that some could be intra-specifically variable. For what is of interest to the scope of this manuscript, E. longirostris and E. florezi very much resemble one another, and future research will be necessary to elucidate whether both are indeed separate species. Thanks to the photos shared with us, we can confirm that Maury's (1982) description and illustrations are a very accurate reflection of the actual morphology of the type specimen. Therefore, Maury's (1982) description of E. longirostris continues to be the clearest and most complete reference so far available for this species.
