Identification.

Sokolov et al. (2004) reviewed the North American species and provided a key for the identification of all but four species ( Anillinus daggyi , Anillinus dohrni , Anillinus longiceps , and Anillinus valentinei ). Subsequently 16 new species were described by Dajoz (2005), Sokolov et al. (2007), Sokolov and Watrous (2008), Sokolov and Carlton (2008, 2010), Sokolov (2011), and Giachino (2011) and three species are transferred to the genus in this work.
