Cryptocotyle lata (Trematoda: Heterophyidae) Adult from a Korean Raccoon Dog, Nyctereutes procyonoides koreensis

초록

Total 513 heterophyid flukes were collected from a carcass of wild Korean raccoon dog, Nyctereutes procyonoides koreensis, in Korea. With morphological and molecular characteristics, the flukes were identified to Cryptocotyle lata. The adult C. lata were minute, transparent, pentagonal, 522 mu m long by 425 mu m wide. Ceca extended into post-testicular region. Ventrogenital sac elliptical, 79 mu m by 87 mu m with genital pore and ventral sucker. Two testes semielliptical and slightly lobed, located in the posterior region, right testis 173 mu m by 155 mu m, left testis 130 mu m by 134 mu m. In a phylogenetic tree, the fluke specimen of this study was grouped with C. lata divergent from Cryptocotyle lingua. We report here N. procyonoides koreensis first as a natural definitive host of C. lata.
