文摘
The subfamily Nasutitermitinae Hare (1937) is a tropical and subtropical group, generally considered as the most specialised subfamily of Termitidae. To highlight some taxonomic inconsistencies, the phylogenetic relationships among seven Australian species, morphologically ascribed to the genera Nasutitermes and Tumulitermes, were studied through the analyses of the mitochondrial markers cytochrome oxidase II and 16S ribosomal RNA genes. In our trees, N. longipennis samples clearly pertain to two different specific entities with an apparently parapatric distribution. Further, the phylogenetic analysis performed on separated and combined data sets shows the placement of Tumulitermes species within a clade grouping Nasutitermes ones, and vice versa. Tests for alternative topologies do not support the monophyly of the genera Nasutitermes and Tumulitermes. Our results confirm the hypothesis that the morphological features used to establish relationships among these species are not phylogenetically decisive.
