Lekanesphaera is a genus of isopods in the family Sphaeromatidae. It was split off from Sphaeroma by Karl Wilhelm Verhoeff, 1943. The type species is L. monodi (formerly Sphaeroma monodi Arcangeli, 1934). Other well-studied species are L. glabella (Madera), L. rugicauda (Baltic), and L. hookeri (from Scotland and southeast Sweden to Italian lagoons). Because they inhabit intertidal zones such as estuaries, their adaptation to diurnal variations in factors such as salinity are often studied.

Caecosphaeroma is a troglodytic isopod genus in the family Sphaeromatidae found in caves of NE and SW France. The genus was split off from Monolistra by Adrien Dollfus in 1896; in both genera, the female carries about 10 fertilized eggs in its external marsupium (brood pouch); they are white in Monolistra but bluish-green in Caecosphaeroma. C. burgundum is the most studied species.

Alpioniscus is a southern European genus of woodlice in the family Trichoniscidae. Alpioniscus consists of two subgenera: Alpioniscus s.s. and Illyrionethes.
