Amazonian Common Mustached Bat

Pteronotus alitonus

French: Ptéronote alitone / German: Amazonas-Schnurrbartfledermaus / Spanish: Pteronotus biogotudo amazoénico

Other common names: Amazonian Mustached Bat

Taxonomy. Pteronotus alitonus Pavan, Bobrowiec & Percequillo, 2018 ,

“Biological Dynamics of Forest Fragments Project (BDFFP) area, 80 km north of Manaus, Brazil (2°20’S, 60°6’W, elevation of 30- 125m).”

Pteronotus alitonus was split from P. rubiginosus based on molecular, morphological, and acoustic evidence; it was referred to in some previous molecular studies as Pleronotus sp. 3 or Pteronotus sp. 1 . Monotypic.

Distribution. The Guianas and N Brazil.

Descriptive notes. Head—body ¢.65-70 mm, tail 24-31 mm, ear 17-19 mm, hindfoot 13-15 mm, forearm 59-64 mm; weight 18-26 g. Pelage is dense and short; color varies from pale brown to reddish. Skull rostrum is robust, and braincase is large and rounded. Condylo-basal lengths are 20-22 mm. Nasal bones form markedly concave area in rostrum at suture of maxillary and frontal bones; they are narrower and slightly upturned in their anterior part. Pterygoid canal has pair of foramina varying from almost indistinct perforations to small pits. Maxillary tooth row length is less than 9-7 mm. Greatest width across molars is more than 8: 1 mm. Additional external and cranial features shared with other species in the subgenus Phyllodia are listed in descriptive notes for Parnell’s Common Mustached Bat ( P. parnellii ).

Habitat. Continuous forests in the Amazon.

Food and Feeding. The Amazonian Common Mustached Bat is insectivorous, but there is no specific information available on prey itemsin its diet.

Breeding. In French Guiana, pregnant and lactating females were found in July, and post-lactating females between August and October.

Activity patterns. The Amazonian Common Mustached Bat shows highest activity levels in forests in contrast to foraging sites over water bodies. Its activity patterns seem to be similar between dry and wet season in the central Amazon. Echolocation calls consist of long CF-FM pulses of ¢.25 milliseconds. Second harmonic has maximum energy at 59-60 kHz.

Movements, Home range and Social organization. The Amazonian Common Mustached Bat exhibits high genetic structuring, which might be consequence of low dispersal capability related to limitations to cross open landscapes in the Amazon region.

Status and Conservation. Not assessed on The [UCN Red List.
