|Researched by||Andrew Hosie||Refereed by||Admin|
|Other common names||-||Synonyms||Sphaeroma rugicauda Leach 1815|
Recorded distribution in Britain and IrelandCommon in brackish waters around the UK but few records in Ireland.
Global distributionFound from the Baltic south to the Bay of Biscay and a single record from Morocco.
HabitatLekanesphaera rugicauda is found in the upper intertidal of brackish waters. Often in salt marsh pools where it can be found burrowing or under rocks and wood.
- Body broadly oval, grey typically with medial longitudinal stripe of yellow, orange or pinkish red.
- Dorsal surface of pleotelson granulated, extending beyond tips of uropods in adult males.
- Outer rami of uropod exopod almost smooth.
Additional informationThere are two other species which may also be found in brackish waters in the UK and Ireland, Lekanesphaera levii and Lekanesphaera hookeri. These may be distinguished by having a smooth pleotelson and having two rows of distinct tubercles respectively, in contrast to the granulated pleotelson of Lekanesphaera rugicauda. The related species Sphaeroma serratum is not found in brackish habitats and can be distinguished by the distinctly serrate uropod exopod and a smooth pleotelson.
