Abstract

Two lichomolgoid copepods, Lichomolgus inflatus Tanaka and Philoconcha paphiae Yamaguti, both known very rarely since the original descriptions, are redescribed based on the specimens discovered as associates with the bivalve Dosinorbis japonicus from the Korea Strait. Lichomolgus inflatus is very closely related to L. chamarum Humes, but can be differentiated by the features of the rostrum and genital double-somite. Philoconcha paphiae is found to have an extremely variable leg armature. This is the first discovery of the two species of copepods outside the Japanese waters.

살갗살이과(Lichomolgidae)에 속하며 원기재 이후 그 기록이 매우 드물었던 요각류 2종 Lichomolgus inflatus Tanaka와 Philoconcha paphiae Yamaguti가 남해도에서 떡조개 (Dosinorbis japonicus)로부터 발견되어 재기재하였다. Lichomolgus inflatus는 L. chamarum Humes와 매우 유사하나 이마돌기와 생식이중절의 특징으로 서로를 구별할 수 있다. Philoconcha paphiae는 매우 변이가 심한 다리 강모식을 가지는 것이 발견되었다. 이 두 종에 대한 본 기록은 일본 외의 지역에서는 처음이다.
