Female and male Entevocola sydnii Chatton & Harant (Copepoda: Cyclopoida: Ascldicolidae) living in compound ascidians

摘要

-The specimens of Enterocola sydnii Chatton & Harant, 1924, as studied for this paper, were found in the following compound ascidians (Aplousobranchia: Polyclinidae) collected by the author at Roscoff in 1992: females and males in Aplidium argus (Milne Edwards 1841); females and males in A. nordmanni (Milne Edwards 1841); and females in A. turbinatum (Savigny 1816). The female E. sydnii is fully redescribed, based mainly on specimens in A. argus. The male E. sydnii is described for the first time, primarily from specimens in A. nordmanni. In living females, the color of the ovarian eggs in the metasome is a pale rose.
