G. Costanzo et al., COPEPODIDS OF DORIDICOLA-LONGICAUDA (CLAUS, 1860) (COPEPODA, POECILOSTOMATOIDA, LICHOMOLGIDAE) ASSOCIATED WITH SEPIA-OFFICINALIS L, Journal of crustacean biology, 14(3), 1994, pp. 601-608
The five copepodid stages of Doridicola longicauda (Claus, 1860), a po
ecilostomatoid copepod (family Lichomolgidae) living on the gills of S
epia officinalis in Lake Fare, Messina, Italy, are described. Sexual d
ifferentiation first occurs in copepodid V, in which the male and fema
le maxillipeds are differently formed. The adult stages of the two sib
ling species D. longicauda (Claus, 1860) and D. sepiae (Izawa, 1976) a
re compared.
