Takagi (1965) originally divided the genus into seven species groups. According to Masunaga et al. (2005) and Masunaga & Saigusa (2010), the genus can be divided into two clades: one containing the rectus species group (including the type species), and the other containing all other species groups, for which the authors intended to propose a new genus. The latter clade they also consider to be the sister group of Thambemyia.[5][3]
