Une nouvelle espèce Méditerranéenne de Chrysopetalidae (annélides polychètes)

The Chrysopetalidae family is represented in the Mediterranean Sea by two species of the genus Chrysopetalum, C. debile (Grube, 1855) and C. caecum (Langer-Hans, 1880). A third form has been observed on the Lebanese coast, on organogenous sandy beds, at depths of 10 metres, by Laubier (1966, p. 11) under the name "Chrysopetalidae gen. sp.?". New collections conducted on the Spanish Catalan coast (bay of Rosas) lead Ramos (1973) to refer this species to the genus Heteropale Johnson, 1897. [...]
