740E87807E7EFFB65F1DF9ADFBD8A6DD.taxon	discussion	Remarks. Presently, the genus Moolapheonoides contains 8 species worldwide (WoRMS, 2016). Among them, M. acutifalcatus is closely similar to M. kadee Barnard, 1974, but distinguished from the latter in having short accessory flagellum, strongly curved dactylus on gnathopod 2, and truncate dorsal keel of urosomite 1. Our male specimen is accorded with Kobayashi and Ishimaru (2005) ’ s original description, except palmar corner of gnathopod 2 blunt. In this paper the genus Moolapheonoides is reported from Korea for the first time.	en	Kim, Young-Hyo, Heo, Jun-Haeng (2016): Four new records of the gammarids (Crustacea, Amphipoda) from Korean waters.

740E87807E7CFFB75CF4FB01FAE4A30C.taxon	discussion	Remarks. The monotypic genus Gordonodius Ariyama, 2011 is characterized by the presence of dorsal distinct projections and accessory flagellum in male and presently only one species, G. zelleri, has been reported from Japan. Our female specimen is accorded with Ariyama (2011) ’ s description, however, Korean specimen also display some important differences, such as the longer and slenderer peduncular articles 1 ­ 3 of antenna 1, coxa 1 more acute distally, and variation in color pattern. However, as we have not had the opportunity to examine the Japanese material of Ariyama (2011), we cannot confi­ dently determine whether our species is novel. Therefore at this time we conservatively maintain our Korean specimens as G. zelleri until a detailed, comparative study can be made on the Japanese material.	en	Kim, Young-Hyo, Heo, Jun-Haeng (2016): Four new records of the gammarids (Crustacea, Amphipoda) from Korean waters.
