A tiny egg-eating nudibrach, Favorinus tsuruganus Baba & Abe, 1964 (Nudibranchia: Gastropoda) new to Korean water

초록

Favorinus tsuruganus Baba & Abe, 1964 was reported based on a specimen collected from Deunggado, Tongyeong, Gyeongsangnam-do, South Korea in October 2022. This species was initially recorded from Tsuruga Bay, Japan, and widely distributed across the western Pacific region. This species can be distinguished from other congenerics by the following characteristics: translucent white body, translucent black rhinophores with three lamellae, orange-colored digestive glands, black apical marking on each ceras, cleioproctic anus and uniseriated radula without denticles. This study includes morphological descriptions, SEM photograph of radula, and DNA barcoding analysis based on mitochondrial COI genes. The uncorrected pairwise genetic distance of F. tsuruganus was calculated to range from 0.0% to 1.07%.
