Une équipe de spécialistes
hollandais de chauve-souris a découvert une nouvelle espèce de chauve-souris au
Gabon (Peereboom and van Lieshout, 2015). La chauve-souris insectivore Scotophilus nux
a une répartition qui s’étend sur une bande en Afrique de l’ouest et du centre,
depuis la Guinée jusqu’au Ghana, Cameroun, et à travers la République du Congo
et le nord de la RDC à l’Ouganda et le Rwanda. Cependant, sa répartition est
beaucoup plus large. La nouvelle étude confirmerait l’extension de son aire de
répartition jusqu’au parc national de Loango dans le sud du Gabon. Les
chercheurs ont pris en même temps des mesures à partir de chauves-souris
capturées vivantes et des enregistrements des cris d’écholocation. Cependant,
les mesures du crâne et des dents seraient également requises pour
définitivement confirmer Scotophilus jusqu’à l’espèce. Ainsi, les
résultats de l’équipe ont permis d’identifier leur spécimen comme étant Scotophilus
cf. nux.
La même équipe avait auparavant identifié pour la première fois une autre
espèce de chauve-souris vespertilionidés
au Gabon (Peereboom et al. 2012).

A team of Dutch bat specialists have discovered a new vesper bat species record for Gabon (Peereboom and van Lieshout, 2015). The insectivorous nut-colored yellow bat Scotophilus nux is known to occur in a band across west and central Africa, from Guinea to Ghana, Cameroon, and through Congo and northern DRC to Uganda and Rwanda, but is believed to be more widespread. The new study would confirm its range extension to Loango NP in the south of Gabon. The researchers took measurements from live-caught bats as well as recording echolocation calls. However skull and dental measurements would also be required to decisively confirm Scotophilus to species level. As a result, the team identified their individual as Scotophilus cf. nux.

The same authors have previously identified the first record for another species of vesper bat in Gabon (Peereboom et al. 2012).
