New Record of Syngnathoides biaculeatus (Bloch) (Gasterosteiformes: Syngnathidae) from Korea

Two specimens of the syngnathid Syngnathoides biaculeatus were collected from the coastal waters of Geoje Ialand and Tongyeong, Korea, represent first record of the species and the genus from Korea. This species is characterized by the following combination of characters: caudal fin absent; opercle without keel; superior and inferior trunk ridges continuous with their respective tail ridges; lateral trunk ridge deflected dorsal behind anal ring. Tail shorter than head and body hexagonal in its subdorsal part, posterior quadrangular, rapidly tapering, without caudal fin, prehensile. Head essentially in line with longitudinal axis of body or bent very little. New Korean names are proposed, "Jal-pi-sil-go-gi-sok" for the genus Syngnathoides, and "Jal-pi-sil-go-gi" for S. biaculeatus. 경남 통영과 거제에서 실고기과 어류 2개체가 채집되었다. 한국에서는 미기록종인 Syngnathoides biaculeatus로 동정되었고, 본종이 포함되는 속(Syngnathoides) 역시 한국 미기록으로 확인되었다. 본 종의 형태는 긴 형태를 띠며, 체륜상 골판으로 덮여 있다. 몸통부는 두부와 꼬리부보다 굵으며, 두부와 몸통은 일자형이다. 주둥이는 긴 관모양이며, 눈 후연에서 아가미 후연까지의 길이보다 길다. 등지느러미는 몸의 뒤쪽에 위치하고, 매우 작은 뒷지느러미가 있으며, 연조이다. Genus Syngnathoides는 "잘피실고기속", S. biaculeatus는 "잘피실고기"로 각각 국명을 신칭한다.22Nkc

A deep-sea eelpout Pachycara matallanasi (Perciformes: Zoarcidae: Lycodinae) from the Eastern North Pacific Ocean

The zoarcid genus Pachycara Zugmayer, 1911 comprising 27 deep-sea eelpouts, all inhabiting the upper bathyal to abyssal zone, 13 species in the Pacific Ocean and 14 species in the Atlantic, Indian and/or Antarctic Oceans. And then type specimens of 27 species were collected between 300 m and 4,450 m depth. Considerable systematic confusion exists in the genus Pachycara and various reviews have tried to establish diagnostic characters. The Pachycara is defined by a combination of the following characters: body robust flesh firm pelvic fins, scales, lateral line(s) and pseudobranch filaments present or absent suborbital pores 5-7 vomerine and palatine teeth present mental crest absent suborbital bones 6-8 parasphenoid wing below mid-height of trigeminofacialis foramen platopterygoid series well developed pyloric caeca present total vertebrae 92-125. A deep-sea eelpout Pachycara matallanasi Corbella and Møller, 2014 was described from the Solomon Sea, Western South Pacific at 7°49′4″S, 156°02′8″E, December 2006, around 4,400 m depth. And, three specimens of P. matallanasi were additionally collected from the Eastern North Pacific at 10°32′4″N, 131°55′4″W during the Korea Deep Ocean Study (KODOS) of KIOST, R/V ONNURI, February 2014, by a Bait-trap Lander, around 5,100 m depth. Until now, only known from a single type locality in the Solomon Sea, and from the locality to the sampling site of this stimens of 27 species were collected between 300 m and 4,450 m depth.
