内容記述
"The blackfly subgenus Wallacellum of genus Simulium (Diptera: Simuliidae) is a small subgenus, represented by 17 species, and distributed insularly in Southeast Asia. Phylognetic relationships among Wallacellum were surveyed using mitochondrial sequences of cytochrome c oxidase subunit I (COI) and 16S ribosomal RNA (16S rRNA) regions. Combined with morphological data, Wallacellum was divided into three groups (A, B, C). The group A has ancestral characters and is distributed widely, whereas the group B has derivative characters and is distributed only in the central Philippines, suggesting that the group A is basal and might have been distributed widely in the early period, and then species radiation of the group B occurred in the center of the distribution of this subgenus. The interspecific and intraspecific divergence values were not overlapped both for the COI and 16S rRNA regions, indicating that both regions were effective to identify the species of Wallacellum."
