Although this species is widespread in Middle America, it has been
known previously from Nicaragua only by a specimen from "Chontales"
(Miller, 1902:402). All of our specimens were captured in mist nets.
Two adult females (one taken on 28 February and the other on 8 March)
each carried a single embryo (13 and 18 mm in crown-rump length,
respectively); a female taken in April was lactating and had a flaccid
uterus suggesting relatively recent parturition. Adult females captured
in the months of June, July, and August evidenced no sign of
reproductive activity. Two of these were in dark, fresh pelage, but one
captured on 24 June and another on 28 July were molting. In both
individuals, active molt evidently had slowed or subsided and remnants
of the old pelage (rich ochraceous orange) were confined to a narrow
strip at the lateral edges of the body.
We tentatively apply the subspecies name _fuscus_ to our Nicaraguan
bats on geographic grounds; one of us (Smith) currently is
investigating geographic variation in the genus _Pteronotus_.
