New observations on the morphology of the vomeronasal organ (VNO) of Pteronotus macleayii and P. quadridens indicate that of the six known species of the genus Pteronotus, four (parnellii, gymnonotus, macleayii, and quadridens) are endowed with a functional VNO, whereas P. personatus is not, and information is lacking on the sixth species, P. davyi. Such incongruity of a conservative structure like the VNO within the genus Pteronotus is unexpected. Among the remaining mormoopids, Mormoops megalophylla has a rudimentary VNO, but observations on the VNO of M. blainvillii are required before discussion of the VNO of the genus Mormoops can be undertaken.


De nouvelles observations morphologiques de l'organe voméronasal de Pteronotus macleayii et de P. quadridens indiquent que des six espèces du genre Pteronotus, quatre (parnellii, gymnonotus, macleayii et quadridens) sont dotés d'un organe voméronasal fonctionnel, tandis que P. personatus ne l'est pas. Il n'existe pas d'information sur la dernière espèce du genre, P. davyi. Une telle incongruité d'une structure de base comme l'organe voméronasal au sein du genre Pteronotus était inattendue. Chez les autres mormoopids, Mormoops megalophylla a un organe voméronasal; toutefois des observations de cet organe chez M. blainvillii sont nécessaires avant toute discussion au sein du genre Mormoops.
