The snailfishes (Scorpaenoidei: Liparidae) is a large group requiring taxonomic reviews because of a potential taxonomic confusion due to its great similarity in external morphology between species and a variation of its body color with size. Molecular phylogeny and taxonomic review were conducted for 10 species in 3 genera reported around the Korean waters, which facilitate understanding interrelationship within its family, and further management of fisheries resources. Molecular phylogeny using mitochondrial COI (mtCOI) and nuclear RAG2 (nRAG2) sequences indicates that the reciprocal monophyly of the three genera (Careproctus, Crystallichthys, and Liparis) were supported except Crystallichthys matsushimae, being closely related to Careproctus notosaikaiensis in only mtDNA COI topology. Liparis ingens Gilbert and Burke (1912) was reported as a distinct species differing from L. ochotensis. However, in the present study, comparing L. ingens from Korea with L. ochotensis from Japan and Russia, the two species were well corresponded in their morphology and molecule, therefore, we suggest L. ingens to be treated as a junior synonym of L. ochotensis.

Maturity and spawning of the snailfish, Liparis ochotensis was investigated based on samples collected by gill net in the East Sea of Korea from December 2008 to December 2009. The average total length of L. ochotensis was 63.4 cm and 64.1 cm for females and males, respectively. Gonadosomatic index (GSI) began to increase in July, reaching a maximum in November, then began to decrease in December. Monthly changes in the GSI values of L. ochotensis were similar for females and males. Annual reproductive cycle of this species can be divided into five successive stages in females: early growing stage (May), late growing stage (June to July), mature stage (August to September), ripe and spent stage (September to December), and recovery and resting stage (January to April). Males show four successive stages; growing stage (May to July), mature stage (August to September), ripe and spent stage (September to December), and recovery and resting stage (January to April). Relationship between total length (TL) and fecundity (F) was F=$0.00003TL^{4.002}$ ($R^2$ = 0.703), and F increased with TL. Total length at 50% group maturity was estimated to be 55.8 cm. Our findings suggest that the spawning period takes place from September to December, with the main spawning period occurring from October to December.

쏭뱅이목, Sorpaeniformes의 꼼치과, Liparidae 어류는 남극, 북극, 대서양 및 태평양에 걸쳐 광범위하게 분포하며(Nelson, 1994), 전세계적으로 24속, 317종(Froese and Pauly, 2003), 우리나라에는 2속 7종만이 보고되어 있다(Kim and Kim, 1997). 국내에서는 꼼치과 어류증 꼼치, Liparis tanakae가 식용으로 즐겨 이용되며, 겨울철 남해안에서 주로 어획된다. (중략)

A single specimen of Liparis punctulatus (30.9 mm standard length) belonging to the family Liparidae, was collected in the waters off Busan on 4 August, 2016. This species is characterized by a single pair of nostrils, unlike other Liparis species. It is distinguished from L. ochotensis by the numbers of dorsal, anal, pectoral fin rays and the location of the gill opening (above the pectoral fin in L. punctulatus vs. extending ventrally in front of the pectoral fin). In the molecular analysis, 514 bp of 16S rRNA gene of the specimen in this study were identical to that of L. punctulatus from NCBI GenBank (K2P distance < 0.002). This is the first record of the species in Korea based on a voucher specimen, and we follow the Korean name "Kko-ma-kkom-chi" for this species proposed by Myoung et al. and Kim et al.
