Natural history
Hill (1964) describes Glyphonycteris daviesi (Barticonycteris daviesi) based on an adult female specimen captured by JN Davies during a Bangor University (United States) expedition to a primary forest reserve parallel to the Potaro-Bartica road, Essequibo. , Guyanese.
Hence the specific name daviesi, which is the Latinization of the proper name Davies in honor of this American mastozoologist and collector of the type specimen (catalog No. BMNH 64.767).
The use of the common name “Davies’s gray-haired bat” and not “Davies’s elder bat” although the latter is the literal translation in Spanish of the common name in English “Davies’s graeybeard bat”, since gray beard “graeybeard” and by extension hair grey-haired, is consistent with the characteristic coloration of this group of bats, very evident in G. sylvestris, the type species of the genus.
On the contrary, it is unknown if they reach particularly advanced stages of old age, nor are characteristics that give them the appearance of “elderly” detected, beyond, of course, the gray-looking coat.
In Ecuador Glyphonycteris daviesi has been referred to as a rare species, probably due to the low abundance with which it has been detected, only 16 specimens have been reported captured in Ecuador, a situation that is common in the rest of its distribution.
Most of these records come from the eastern slope of the Andes (provinces of Orellana, Pastaza, Sucumbíos and Zamora Chinchipe) and only two from the western slope (provinces of Imbabura and Los Ríos).
Etymology
Glyphonycteris is a compound generic name, formed by the fusion of the Greek words “Glypho” (to carve or sculpt) in allusion to the dermal canal that this species presents in the chin and “Nycteris”, which means bat.
Habitat
Amazonian tropical humid forest, Chocó tropical humid forest
