Systematics

The exact systematic placement of the genus remains uncertain; it is the only member of the Colilodionini tribe, sharing certain characteristics with Clavigeritae, where it was originally placed by Claude Besuchet in 1991,^[1] and others that resemble the Pselaphitae.^[3][4] Eight species have been described:^[4]
