This small Neotropical _Myotis_ has been reported from Nicaragua only
from the Caribbean lowlands of Zelaya (Davis _et al._, 1964:379). Our
records indicate that it is widely distributed in the republic but
evidently nowhere common. Females taken on 5 March and 6 August each
carried a single embryo (7 and 13 mm in crown-rump length,
respectively), whereas one obtained on 21 July evidenced no
reproductive activity. Richard K. LaVal currently is studying the
_Myotis nigricans_ complex; pending his revision our specimens are
tentatively assigned to _M. n. nigricans_.
