Locality : Wimereux, France Lekanesphaera is a genus of isopods in the family Sphaeromatidae.

It was split off from Sphaeroma by Karl Wilhelm Verhoeff, 1943.:[1] The type species is L. monodi (formerly Sphaeroma monodi Arcangeli, 1934).

[2] 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.

It is best found in the upper intertidal of brackish waters, such as salt marsh pools, under rocks and wood.
