Doridicola similis (Copepoda: Poecilostomatoida: Rhynchomolgidae) Associated with Sepioteuthis sp. (Cephalopoda: Myopsida: Loliginidae), New to Japan

Abstract

Female and male specimens of Doridicola similis Ho and Kim, 2001 (Copepoda: Poecilostomatoida: Rhynchomolgidae) from the gills of the loliginid squid Sepioteuthis sp. (called shiro-ika) (Cephalopoda: Myopsida: Loliginidae) in coastal Pacific waters of central Japan are described as a new country record. This collection represents the second record of D. similis and expands its distribution range from the Gulf of Thailand (type locality) northeast to the western North Pacific Ocean off central Japan.
