Taxonomy. Chilonycteris parnellii pusillus [sic] G. M. Allen, 1917, View in CoL
“Arroyo Salado, Santo Domingo,” Dominican Republic.
Pteronotus pusillus was formerly classified as a subspecies of P. parnellir, but here it is considered a distinct species. Fossil subspecies gonavensis, described by K. F. Koopman in 1995 from an owl pellet deposit found in a cave near En Café, Gonave Island, off western Hispaniola,is considered a temporal variation of the population currently inhabiting Hispaniola (i.e. P. pusillus). Monotypic.
Distribution. Haiti and Dominican Republic. View Figure
Descriptive notes. Head—body ¢. 53 mm, tail 20 mm, ear 18 mm, hindfoot 12 mm, forearm 49-7-52-9 mm. The Hispaniolan Common Mustached Bat is the smallest species of common mustached bat. It is easily distinguished from Parnell’s Common Mustached Bat (P. parnelliz) and the Puerto Rican Common Mustached Bat ( P. portoricensis ) based on smaller external and cranial sizes. Pelage is darker dorsally than ventrally; hairs on back have paler central zone similar to Parnell’s Common Mustached Bat. Skull of the Hispaniolan Common Mustached Bat has delicate rostrum and comparatively robust, globular braincase. Condylo-basal lengths are 17-17-8 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.
Habitat. Dense vegetation in dry thorn scrub and forests or along streams.
Food and Feeding. The Hispaniolan Common Mustached Bat feeds on insects, but there is no specific information available on prey items in its diet.
Breeding. No reproductive activity was observed in Hispaniolan Common Mustached Bats collected in May and August in three distinct localities in Haiti.
Activity patterns. Echolocation calls of the Hispaniolan Common Mustached Bat consist of long CF-FM pulses with most energy at ¢.67-5 kHz.
Movements, Home range and Social organization. Hispaniolan Common Mustached Bats roost in caves with other mormoopids and phyllostomids. There are seasonal changes in colony sizes, probably related to reproductive activity.
Status and Conservation. Not assessed on The IUCN Red List. Hispaniolan Common Mustached Bat is included under Parnell’s Common Mustached Bat, which is classified as Least Concern. It is not particularly abundant compared with other species of mormoopids on Hispaniola.
