Abstract
Neoascarophis sinensis n. sp. collected from the whitespotted conger Conger myriaster (Brevoort) (Anguilliformes: Congridae) in the Yellow and East China Seas, is described using both light and scanning electron microscopy. The new species is characterised mainly by the body size (8.5–10.5 mm in the males, 9.5–14.0 mm in the females), the location of the vulva (near equatorial region of the body), the non-bifurcate deirids, the lengths of the vestibule (40–50 µm in the males, 30–60 µm in the females) and glandular oesophagus (2.5–3.1 mm in the males, 3.1–3.5 mm in the females) and the morphology and length of the spicules (left spicule 400–410 µm, right spicule 130–150 µm). Neoascarophis sinensis n. sp. is the first species of Neoascarophis Machida, 1976 reported from the anguilliform fish and is also the only species of this genus found in the Chinese waters.
