REDESCRIPTION AND SYSTEMATIC STATUS OF NEOCAPILLARIA PHOXINI YU ET WANG, 1994 (NEMATODA: CAPILLARIIDAE)

Re-examination of the syntypes of the capillariid nematode Neocapillaria phoxini Yu et Wang, 1994, the type species of Neocapillaria Yu et Wang, 1994, described from the intestine of the freshwater fish Phoxinus lagowskii variegatus Gunther (Cyprinidae) from China, confirmed its morphological similarity with species of Freitascapillaria Moravec, 1987, to which it is transferred as Freitascapillaria phoxini (Yu et Wang, 1994) comb. n. Consequently, Neocapillaria Yu et Wang, 1994 (a homonym to Neocapillaria Moravec, 1987) and Sinocapillaria Moravec et Spratt, 1998 become junior synonyms of Freitascapillaria. Skrjabinocapillaria gigantea is transferred to Freitascapillaria as F. gigantea (Wang, 1984) comb. n.

Rediscovery of the sea cucumber "Toxodora" pacifica Ohshima, 1915 (Echinodermata : Holothuroidea : Apodida)

The apodous holothurian species originally described by Ohshima ( 1915) as Toxodora pacifica has been rediscovered, and its known geographic range extended from Suruga Bay, Japan to the western side of the Yellow Sea, China. As the genus name Toxodora is no longer available, a new genus name, Neotoxodora Liao, Pawson, and Wei, is proposed. The type material of Neotoxodora pacifica is lost, and a Neotype is named for this species.
