Contribution to the study of the tribe Typhlotricholigioidini Roja, 1953 (Isopoda, Oniscidea, Trichoniscidae)

Following a historical review of the tribe Typhlotricholigioidini, we define the tribe and the genera which, according to our view, are included in it. The genus Brackenphiloscia Ortiz, Garcia Debraz and Lalana, 1999 we interpret as part of this tribe. The examination of the holotype of the species Caucasonethes borutzkyi Verhoeff, 1932, the type species of the genus Caucasonethes, as well as individuals from the type series of several species attributed to the genus Amerigoniscus Vandel, 1950, allowed us to endorse the viability of the synonymy established by Vandel (1953a): Caucasonethes Verhoeff, 1932 syn. Amerigoniscus Vandel, 1950.
