Wash. 49(2), 1982, pp. 169-175 A New Monogenean and Cestode from the Deep-Sea Fish, Macrourus berglax Lacepede, 1802, from the Flemish Cap off Newfoundland RONALD A. CAMPBELL,1 STEVEN J. CORREIA/ AND RICHARD L. HAEDRiCH2 1 Department of Biology, Southeastern Massachusetts University, North Dartmouth, Massachusetts 02747 and 2 Department of Biology, Memorial University of Newfoundland, St. John's, Newfoundland, Canada, A1B3X9 ABSTRACT: A new trematode, Macruricotyle newfoundlandiae sp. n. (Monogenea: Diclidophoridae), and a new cestode, Parabothriocephalus macruri sp. n. (Cestoda: Parabothriocephalidae), are de- scribed from 46 specimens of the macrourid fish, Macrourus berglax Lacepede, 1802, taken in the Newfoundland region of the North Atlantic Ocean (45°31'-46043'N, 44°08'^8°23'W). Macruricotyle newfoundlandiae is the second species named in the genus, and is distinguished from M. clavipes Mamaev and Lyadov, 1975 by its much larger pharynx, smaller first pair of clamps, "callous" on the second and third pairs of clamps, and the shape of the distal median sclerite in the posterior clamp jaw. Parabothriocephalus macruri sp. n. is differentiated from the three other species in the genus by its narrow scolex and segment shape, 77-112 testes per segment, and lack of a vaginal armature and sphincter. During May-June 1981, 218 fishes (21 spp.) were examined off the eastern slope of the Grand Bank and in the Flemish Cap area off Newfoundland. In this paper we describe a new species of Macruricotyle (Monogenea) and a new species of Parabothriocephalus (Cestoda) from that collection. Noble et al. (1972) and Zub- chenko (1979, 1981) have reported pseudophyllidean cestodes from Macrourus berglax and other macrourids in the northwest Atlantic, but did not identify them. Specimens of Macruricotyle and Parabothriocephalus are unknown from M. ber- glax or other fishes in this region. Discussion of the entire metazoan parasite fauna of M. berglax and other dominant deep-benthic fishes of this region will be presented in another paper. Materials and Methods Forty-six specimens of M. berglax, taken in 12.5-m Gulf of Mexico shrimp trawls and standard survey-type bottom trawls fished at 367-811 m, were ex- amined at sea. A few fish were moribund when obtained, but most had recently died. Examinations for parasites began immediately. Fish from large samples that could not be examined immediately were refrigerated and examined the following day. Organs and tissues were observed with the aid of a dissecting microscope. The monogenetic trematodes were fixed in cold alcohol-formalin-acetic acid (AFA) without cover-glass pressure. Cestodes were relaxed in tap water for 10-20 min prior to fixation by immersion in AFA. All parasites were later transferred to 70% ethanol prior to staining. Trematodes were stained with Mayer's paracarmine and cestodes were stained in Harris' hematoxylin. Whole mounts were dehy- drated in ethanol, cleared in methyl salicylate, and mounted in Canada balsam. Serial transverse sections, cut at 6 /xm, of mature segments of Parabothrio- cephalus were stained in Harris' hematoxylin and counterstained with eosin. 169 Copyright © 2011, The Helminthological Society of Washington 170 • PROCEEDINGS OF THE HELMINTHOLOGICAL SOCIETY Descriptive measurements are expressed as length by width, and are in microm- eters unless otherwise indicated.
