Resumen:
The genus Noctilio includes the piscivorous N. leporinus and the
insectivoros N. albiventris, which have a distribution restricted to low
and humid coastal areas and the main river basins in America.
Considering the geographic morphometric variation and the molecular
divergence previously documented in genus Noctilio, we analyze
two-dimensional geometric configurations of cranial characters to assess
if the amount of morphological variation or the existence of
morphological discontinuities within Noctilio species is compatible with
the possible existence of several species, as well as their
relationships in a combined phylogenetic reconstruction. The shape and
size variation of cranial characters supports differences among two of
three molecular lineages previously reported in N. albiventris-one
distributed in Central America and North of South America, and the other
distributed in South America. We also recover differences between the
two mitochondrial clades for N. leporinus, one distributed from Mexico
to the west side of the Andes and the Greater Antilles, and the other to
the eastern side of the Andes and the Lesser Antilles. Based on the
combined phylogeny, we recover the paraphyly of N. albiventris, composed
of two morphologically differentiated taxa, and the monophyly of N.
leporinus, composed of two morphologically divergent lineages. The
latitudinal position and environmental variables correlate with cranial
variation and support the geographic pattern of differentiation in the
evolutionary history of Noctilio.
