E63187FBFF87FF95FCDC571AFAAAB177.taxon	discussion	Remarks. Aoroides longimerus Ren & Zheng, 1996 is similar to A. ellipticus Ariyama, 2004, A. myojinensis Ariyama, 2004, and A. secunda Gurjanova, 1951 in having densely setose anterior margins of basis and carpus of gnathopod 1. However, A. longimerus is distinguished from its congeners based on the following features (different characters of A. ellipticus, A. myojinensis, and A. secunda in brackets): 1) gnathopod 1, coxa with four plumose setae and a robust seta anterodistally (vs. 1 long robust seta in A. ellipticus, unarmed in A. myojinensis, and 2 robust setae in A. secunda); 2) gnathopod 1, carpus elongate-ovate (vs. ovate in A. myojinensis and A. secunda); 3) pereopod 3, basis anterior margins sparse with simple setae (vs. setose with plumose setae in A. secunda); 4) pereopod 7, basis slender, elongate ovate (vs. moderate, ovate in A. ellipticus); 5) uropod 3, both rami with robust setae (vs. inner ramus with a robust seta in A. ellipticus, both rami unarmed in A. secunda). The newly recorded species in Korea, A. longimerus, is well accorded with Ren & Zheng’s original description.	en	Shin, So-Yeon, Choi, Jae-Hong, Kim, June, Kim, Kyung-Won, Kim, Sung-Ho Han and Young-Hyo (2025): The marine amphipods (Arthropoda: Crustacea: Malacostraca) fauna from Ulleungdo Island in Korea.
