우리나라의 강원도 동해 주변해역에서 둑중개과 Icelus속에 속하는 한국미기록종 어류 4개체(표준체장 114.2~134.2 mm)를 채집하였다. 본 종은 후두부에 한 쌍의 강한 가시와 몸의 등쪽과 배쪽에 구별되는 비늘 열을 가지고 있고, 체측에 흰색의 벌레먹은 무늬가 나타나며, 두부 뒤쪽에 작은 비늘이 산재하는 특징을 보였다. 이러한 특징을 바탕으로 이 종을 Icelus stenosomus Andriashev로 동정하였으며 국명을 '무늬줄가시횟대'라고 명명하였다.

The larvae and juveniles of Porocottus leptosomus belonging to the family Cottidae were collected (n = 95, 3.9-16.5 mm in body length, BL) from Busan, Korea, in March 2015. The larvae and juvenile were identified using DNA barcoding as P. leptosomus, and their morphological description was presented in detail. The yolk-sac larvae (3.9-5.6 mm BL) body was slightly compressed, the head was large, the eye was round and large, and the anus was before the middle of the body. The preflexion larvae (5.2-10.0 mm BL) body length drastically increased; caudal fin rays began to occur. The flexion larvae (9.4-11.8 mm BL) notochord flexion started; dorsal, pectoral, and anal fin rays began to occur; pelvic fin buds are seen; they possessed a pair of parietal spine; and a pair of supraocular cirri was first to develop. At 12 mm BL, the notochord was completely flexed. The larva stage (3.9-12.6 mm SL) had the stellate melanophores in the head, isthmus, gut, and tail (along to the ventral midline). During the juvenile stage (11.4-16.5 mm BL), melanophores covered the head and began to form five black bands on the side of the body. The larvae of P. leptosomus spent pelagic life, but moved to the bottom during the juvenile stage. The larvae and juveniles of P. leptosomus differ from other cottid larval fishes by body shape, melanophore head pattern, and spine development. P. leptosomus can be distinguished from Porocottus allisi by morphological development and the occurrence of larval fish: preopercular spine development, melanophore pattern, and caudal fin development.
