| Abstract | |
Land planarians (Geoplanidae) are predatory platyhelminths that inhabit mainly forest soils. The subfamily Geoplaninae is exclusive to the Neotropics. Although some phylogenetic studies have included a range of Geoplaninae genera, some, such as Amaga and Bogga, have not yet been considered in detail. This work aims to improve the understanding of the systematics of these two genera, focusing on the morphological and molecular (28S rDNA and COX1 genes) aspects of three species. We examined 13 geoplanin specimens recently collected in Colombia. Two of the described species are new to science (Amaga vesiculosa sp. nov. and Amaga aglandulosa sp. nov.), and Bogga bogotensis is redescribed from newly collected material. Complementary description of Amaga becki is also given from photomicrographs of the type material. The molecular phylogenetic relationships showed that the two new species are monophyletic, while the genus Amaga is merophyletic because it includes Bogga. The morphological reinterpretation of Bogga bogotensis and molecular phylogenies support the view that this species is a member of Amaga. Accordingly, Amaga is rediagnosed and Bogga is considered its junior synonym. (AU) | |
