Lekanesphaera is a genus of isopods in the family Sphaeromatidae. It was split off from Sphaeroma by Karl Wilhelm Verhoeff, 1943.Verhoeff, K.W. Sphaeromiden-studien und buchnerillo N. G. 83. Isopoden-aufsatz. Z. Morph. u. Okol. Tiere 39, 153–175 (1943). https://doi.org/10.1007/BF00684465 The type species is L. monodi (formerly Sphaeroma monodi Arcangeli, 1934).BJM Jacobs - 1987. [BOOK] A taxonomic revision of the European, Mediterranean and NW. African species generally placed in Sphaeroma Bosc, 1802 (Isopoda, Flabellifera … 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.For example

Lekanesphaera rugicauda Lekanesphaera rugicauda, also called a "sea slater," is found in estuaries ranging from the Baltic, down to the Netherlands and British Isles, and south to the Bay of Biscay. It is best found in the upper intertidal of brackish waters, such as salt marsh pools, under rocks and wood.
