  • Genetic and morphological variations of Rhinogobius giurinus were surveyed. Populations of R.giurinus were clearly divided into two forms (Form-A and Form-B). Starch gel variation of this species. Three loci (Aco, Mpi, aGpd) out of 27 showed fixed allelic differences between Form-A and Form-B and they are well differentiated from each other genetically (Rogers' S=0.871). These two forms, moreover, are found to be allopatric in distribution and morphologi cally different in body length and caudal fin color pattern. Therefore, they are considered as two distinct taxa of subspecific rank. In addition, the genetic relationships among 5 taxa within 4 species of the genus Rhinogobius were investigated. Three species of the Rhinogobius brunneus complex (R.sp. OR, R. sp. CB and R. sp. CO) are well differentiated from each other genetically and two taxa of R. giurinus are genetically divergent from three species of the Rhinosotius brunneus complex (average Nei's D=0.603, average Rogers'=0.534).

  • A single specimen of Pseudocaranx dentex (115.8 mm in standard length), belonging to the family Carangidae, was firstly collected by a set net in the coastal waters of Jeju Island on July 14, 2014. This species was characterized by a yellow stripe presented along both sides, a single series of canine teeth arranged on jaws, a black spot on upper margin of opercle, and snout length longer than eye diameter. We newly add this species to the Korean fish fauna and propose its Korean name "Heuk-jeom-jul-jeon-gaeng-i-sok" and "Heuk-jeom-jul-jeon-gaeng-i" for the genus and species, respectively.

  • A single specimen (351.1 mm SL) of the sleek unicornfish, Naso hexacanthus, belonging to Acanthuridae was firstly collected from the coastal waters of Jeju Island, Korea. The species is characterized by having brownish vertical bands on the dorsal fin and two pale purple bony plates on caudal peduncle. We add this species to the Korean fish fauna and propose its new Korean name, "Nam-bang-pyo-mun-jwi-chi."

  • Three juvenile specimens (38.8~51.5 mm SL) of the opistognathid fish, Opistognathus hongkongiensis Chan were collected off the Jeju Island, southern Korea. O. hongkongiensis is characterized by having a large mouth, dark brown vertical bands on sides, and yellow dorsal fin without a black blotch. We described it as the first record to Korean fish fauna, and proposed the new Korean name, "Jul-hu-ak-chi" for this species.

  • The one specimen of Astrabe fasciata, belonging to the family Gobiidae was collected from the Dokdo of East Sea in Korea, and described as the first record from Korea. The specimen is characterized by having two dorsal fins, pectoral fin with free rays (five upper, two lower), protrusion on upper posterior part of supraorbital dermal fold, white spots dispersed on head and five white transverse bends on the body. We proposed its Korean name "Dok-do-eol-ruk-mang-duk-sok" and "Dok-do-eol-ruk-mang-duk" for the genus and species, respectively.

  • Fifteen gobids specimens first collected from the southern coastal waters of Tongyeong, Gyeongsangnam-do, were identified as the Suruga fundicola from Korea. The species, representing a new Korean record, is characterized by having VII-I, 16~17 dorsal fin rays, I, 15~16 anal fin rays, 37~42 lateral line scales, notably large eye and narrow interorbital space, scaleless cheek and opercle, no babel, teeth rather strong, and 6~7 dusky spots on sides. A new Korean name, "Keun-nun-mangduk-sok" and "Keun-nun-mang-duk" is proposed for the genus and species, respectively.

  • A taxonomic study of the family Zoarcidae was conducted using fish collections deposited in the Department of Biology, Chonbuk National University, Jeonju, Korea and the East Sea Fisheries Research Institute, Korea. Among these collections, the following four species of the genus Lycodes are recognized as the first records for Korea; L. sadoensis, L. japonicus, L. pectoralis, and L. sigmatoides. These species are here redescribed and figured, with their distributions and a provisional key to five genera and eleven species of the family Zoarcidae from Korea.

  • Fine structure of spermatozoa of the bastard halibut (Paralichthys olivaceus) is described. Its structure is characterized by acrosomeless, having a spherical head region and a small mid piece containing five mitochondria disposed one row. The flagellum inserts centrally on the nucleus and has lateral ribbons. The present study supports the suggestion that spermatozoal ultrastructure is of taxonomic importance and may be a phylogenetic criterion in teleostei.

  • Four specimens (114.2~134.2 mm SL) of Icelus stenosomus Andriashev, family Cottidae, were collected from Goseong-gun, Gangwon-do, East Sea of Korea. They were identified based on the following characters : a pair of strong spines on occipital region, distinct row of scales on both dorsal and ventral sides of body, vermiculate white lines on dorsal side of body, and small prickled scales scattered sparsely on the head. We propose a new Korean name for the species as a new Korean name : 'Mu-nui-jul-ga-si-hoet-dae'.

  • A single serranid specimen of Epinephelus radiatus was collected by a hook for the commercial longline fisheries occurred near Marado, Jeju Island, Korea. The present specimen was characterized by five irregular dark brown bands passing downward and forward from upper edge of body, scales in longitudinal row 107, and pored lateral line scales 55. This species is easily distinguishable from the morphologically similar Korean serranid species of E. poecilonotus based on band patterns on body. That is, the former has five irregular oblique dark-edged brown bands, and the latter has several long horizontal bands on lateral body. We propose a new Korean name, "Ma-ra-bari," for Epinephelus radiatus.
