Abstract

Two ampithoid species, Ampithoe lacertosa Bate and A. tarasovi Bulycheva, are redescribed. A. tarasovi has been misidentified as A. lacertosa in Korea. A. tarasovi can be distinguished from A. lacertosa in having the following characteristics: the apical and medial lobes of outer lobe are separated in the lower lip, the carpus of male gnathopod 1 is about 1.4 times as long as the propodus, the palm of male gnathopod 2 has a sloped quadrate hump and a posterodistal tooth, the peduncle of uropod 3 is approximately 2 times as long as the rami, and the length of the carpus is longer than that of the propodus of female gnathopod 1. This study provides detailed descriptions and figures for both species. A. tarasovi is reported for the first time as a member of the Korean fauna.
