A newly recorded chaetodontid species, Chaetodon speculum Cuvier, 1831 was collected in July, 2021 from Pohang, Korea. Its body color is yellow with black stripe across the eyes and a large spot occupying one fourth of the upper part of the body. C. speculum is very similar to congeneric species, C. zanzibarensis, but it can be distinguished by the size of the spot, shape of the lateral line, number of longitudinal line scales and geographic distribution. C. speculum is readily identified between post-larval stage and adult stage because of its similar external shape. Molecular analysis based on mitochondrial DNA COI sequences showed our specimen perfectly matched C. speculum. Therefore, we propose the new Korean name, “Heug-jeom-na-bi-go-gi” for C. speculum.

하늘소아과 검정삼나무하늘소속의 미기록아속인 호리검정삼나무하늘소아속(신칭)에 속하는 Ropalopus (Pronocerodes) aurantiicollis Plavilstshikov, 1940의 한반도 분포를 처음으로 보고한다. 형태적 기재와 사진, 국내 검정삼나무하늘소속의 검색표를 함께 제공한다.

창날개뿔나방과의 모래창날개뿔나방(Alloclita mongolica Sinev)을 국내에서 처음으로 보고한다. 본 보고는 모래창날개뿔나방속(Alloclita) 의 국내 첫 기록이며, 모래창날개뿔나방의 세계 분포 상 최남단 기록이기도 하다. 국내 채집기록으로 보아 모래창날개뿔나방은 주로 해안사구에 서 식하는 것으로 보인다. 이 희귀종의 외부 형태 및 수컷 생식기의 특징을 기술하고 사진을 도시하였다.

Two specimens of Hemitrygon izuensis (395.8-471.5 mm in disc width), belonging to the family Dasyatidae (Myliobatiformes), were collected from the waters off north-eastern Jeju-do Island in June 2016 and Pohang in August 2019. This species was characterized by having no spots on dorsal side of disc, white ventral tail fold and short preorbital snout length (15.6-18.3% of disc width). This species is similar to H. akajei and H. sinensis reported in Korea, but differs in small denticles on mid-line of dorsal surface of disc (absent in H. izuensis vs. present in H. akajei and H. sinensis), the length of ventral tail fold (28.1-31.0% in H. izuensis vs. 48.0-48.6% in H. akajei vs. 45.0% in H. sinensis), color of ventral tail fold (white in H. izuensis vs. black in H. akajei and H. sinensis) and small tubercles on the posterior part of tail (absent in H. izuensis vs. present in H. akajei and H. sinensis). We suggest a Korean name for H. izuensis as “I-ju-gal-saeg-ga-o-li” following Kim et al. (2019).
