SKRJABILLANUS CYPRINI N. SP. (NEMATODA, DRACUNCULOIDEA) FROM THE SCALES OF COMMON CARP CYPRINUS-CARPIO (PISCES) FROM HUNGARY

A new species of the histozoic nematode, Skrjabillanus cyprini n. sp., is described from the subsquamal part of the scales of common carp Cy prinus carpio L. from Lake Balaton, Hungary. It differs from the other three congeneric species mainly in possessing an extremely small, ova l-shaped buccal capsule with a large tooth at the bottom, in the shape of the cephalic end (somewhat bulbously inflated, truncated anteriorl y), the extent of the oesophageal glands and body size (body length of male and female 1,800-3,000 mu m and 3,200-4,100 mu m, respectively). A key to the identification of Skrjabillanus spp, is provided.
