Rem.:

freshwater, rarely in coastal brackish pools.
Incomplete data.
After Heron & Damkaer (1976, Table 2) ratio anal somite/uropod (= caudal rami) 6/11; with metasomal wings.
For Wilson & Tash (1966, p.562) this species does not appear to be closely related to any known species but can be assigned on the basis of characters of A1 and female P5 to a broadly defined group that includes E; composita and E. gracilicauda.
