摘要
Phylogenetic relationships of the genera composing the Neotropical bat family Phyllostomidae are presented based on restriction-site variation from 18 restriction endonucleases within the transcribed portion of the ribosomal-DNA gene complex. Restriction-site variation ranged from conservative or plesiomorphic in Macrotus and Desmodus to rapidly evolving in the Choeronycteris group. However, no strong correlation was observed among the magnitude and extent of variation when restriction-site data were compared with other data sets. It is concluded that in phyllostomid bats, punctuated bouts of morphologic, karyotypic, and ribosomal-DNA restriction-site evolution have different underlying causes. Major systematic conclusions include: establishment of the subfamily Vampyrinae is supported by restriction-site data; recognition of the subfamilies Macrotinae and Micronycterinae is proposed; major reorganization of the subfamily Phyllostominae is supported by restriction-site data.
