Abstract

Yorkeria chonburiensis n. sp. (Tetraphyllidea: Onchobothriidae) is described from the spiral intestine of a specimen of the brownbanded bamboo shark, Chiloscyllium punctatum, collected from the Gulf of Thailand, Chon Buri Province, Thailand. Yorkeria chonburiensis n. sp. is distinguished from all other species of Yorkeria by the pattern of proglottids (craspedote as opposed to acraspedote) and the proglottid number (more than 168). The new species is larger than all other members of Yorkeria, and the medial hooks are slightly larger than the lateral hooks with a ratio of 1:1.87–1:1.96. The position of the genital pore is 29–34% from the anterior margin of proglottid, greater than all other members of Yorkeria.
