Encentrum striatum Althaus, 1957

A single specimen of E. striatum was found in psammon from the Côte d’Azur at Îlot de la Fourmigue, 3.5 km off shore, depth 15 m, June, water temperature 16 °C. The species was originally described from psammon of the sea water aquarium at Varna, Black Sea, Bulgaria (Althaus 1957), and reported from psammon of sandy beaches from the North Sea, island Sylt, Germany (Tzschaschel 1979), and from hygropsammon of a saline backwater- pool in the Santa Rosa Sound, Gulf of Mexico, Florida, U.S.A. (Turner 1990).

The trophi need redescription as SEM (Fig. 27 D) shows a more complicated morphology with differences in number of apical rami teeth and preuncinal teeth, and shape of intramallei and supramanubria, that could not be observed by light microscopy (Althaus 1957; Tzschaschel 1979). Such a redescription awaits discovery of additional specimens.
