Asellota

Belongs within: Isopoda.
Contains: Asellidae, Stenasellidae, Protojaniridae, Stenetrium, Microparasellidae, Janiridae, Nannoniscidae.

The Asellota are a group of aquatic isopods. The members of the Aselloidea are freshwater, while the members of the other superfamilies are marine. The Janiroidea are marked by a tendency to progressive fusion of the free pleonites into a single pleotelson (Henry et al. 1986).

Characters (from Menzies & Kruczynski 1983): First and second pairs of pleopods modified, unlike succeeding biramours pairs. Uropods usually biramous, tubular, leaf-like or absent. Pleon composed of one to three somites including pleotelson. Antenna II with or without antennal scale.
