Extract

Cordonema gen.nov. is proposed for C. venusta sp.nov. (type species), C. longifuniculata (Sobolev, 1952) comb.nov. and C. solonitzini (Sobolev, 1943) comb.nov. The genus differs from Skrjabinoclava Sobolev, 1943, in lacking laterally directed loops of the cordons. Cordonema venusta sp.nov. from Cinclus pallasi from Taiwan, differs from Cordonema longifuniculata in its spicule ratio of 4:1 compared to 2:1. It differs from C. solonitzini in having longer cordons in proportion to body size and in spicule ratio, which is 2:1 in C. solonitzini.

Skrjabinoclava cincli (Yamaguti, 1935) Sobolev, 1943, is redescribed from males and females from the type host, Cinclus pallasi, from Taiwan. Skrjabinoclava decorata (Solonitzin, 1928) Sobolev, 1943, is redescribed from Lonchura fuscans from Borneo.

Skrjabinoclava rallae sp.nov. from Rallus striatus from Palawan differs from S. horrida in its spicule ratio of 4.7:1 compared with 3.6–4:1, and in the structure of the right spicule. It differs from S. cincli in having shorter cordons and spicules. Skrjabinoclava amaurornae sp.nov. from Amaurornis phoenicurus from Palawan differs from S. alii Ali, 1968, in having longer cordons, shorter pharynx, and in the absence of a sclerotized bar connecting the first spines of the lateral rows. It differs from S. cincli in having larger body spines and a right spicule of different shape.

Keys to the genera in Echinuriinae and the species in Cordonema and Skrjabinovlava are included.

We wish to acknowledge the field support by Dr D. S. Rabor, Department of Biology, Silliman University, Dumaguete City, Negros Oriental, Republic of the Philippines, and the technicians of the Parasitology Department of Naval Medical Research Unit No. 2 for general assistance in procurement and examination of hosts. Dr John M. Kinsella kindly read the manuscript and improved it with his advice.
