Monogenetic trematodes from the Bay of Quinte area, Ontario. III. Genera Actinocleidus, Cleidodiscus, Urocleidus, and Tetraoncus

Abstract

In the present, the third in a series of papers on Monogenea from the Bay of Quinte area, 20 species of the subfamily Ancyrocephalinae Bychowsky, 1937 and one species of the family Tetraoncidae Bychowsky, 1957 are presented. The 21 species of the monogenetic trematodes collected are as follows: Actinocleidus fusiformis (Mueller, 1934) Mueller, 1937, A. gibbosus Mizelle and Donahue, 1944, A. mizellei sp. n., A. recurvatus Mizelle and Donahue, 1944. Cleidodiscus alatus Mueller, 1938, C. capax Mizelle, 1936, C. glenorensis sp. n., C. pricei Mueller, 1936, C. robustus Mueller, 1934, C. stentor Mueller, 1937, C. vancleavi Mizelle, 1936, Urocleidus acer (Mueller, 1936) Mizelle and Hughes, 1938, U. adspectus Mueller, 1936, U. dispar (Mueller, 1936) Mizelle and Hughes, 1938, U. ferox Mueller, 1934, U. fundulus Mizelle, 1940, U. furcatus (Mueller, 1937) Mizelle and Hughes, 1938, U. hargisi sp. n., U. principalis (Mizelle, 1936) Mizelle and Hughes, 1938, U. rogersi sp. n., and Tetraoncus monenteron Diesing, 1858. Descriptions and drawings of the new species and comprehensive measurements of the remaining species are presented.

Monogenean parasites of Lepomis gibbosus Linnaeus introduced into the River Durance, France

“…A slightly higher prevalence and abundance of A. oculatus over A. recurvatus was also observed on the River Po in Italy (Galli et al, 2005). In North America, however, A. recurvatus tends to be a frequent species while A. oculatus occurs relatively rarely (Hanek & Fernando, 1972;Beverley-Burton, 1981). Three of the monogenean species found in this study, O. acer, C. robustus (Ancyrocephalidae) and G. macrochiri (Gyrodactylidae), were recorded in Europe for the fi rst time.…”

“…Individual parasite species were identifi ed according to the shape and size of the sclerotised structures of the haptor (anchors, connective bars and marginal hooks) and reproductive organs (copulatory organ and vaginal armament) (Beverley-Burton, 1984;Gusev, 1985) using an Olympus BX 51 light microscope equipped with phase contrast and differential interference contrast. Draw- Hanek & Fernando (1972) in Table 3 …”

Monogenean parasites of introduced pumpkinseed Lepomis gibbosus (Centrarchidae) in the Danube River Basin

“…However, the frequency of its occurrence among native L. gibbosus populations is lower than that of other species, such as the less specific O. dispar or O. ferox (e.g. Allison & McGraw, 1967;Hanek & Fernando, 1972;Wheeler & BeverleyBurton, 1989). Contrary to O. similis, the low infection rate of introduced O. dispar remains comparable among both present and historical findings in the Danubean (Vojtek, 1958;references in Moravec, 2001) and southern European L. gibbosus populations (Kakacheva-Avramova et al, 1978;Galli et al, 2005), suggesting a limited capacity for population growth in new European areas.…”

“…Ancyrocephalus angularis (Mueller, 1934) Mueller, 1936; Cleidodiscus angularis (Mueller, 1934) Wiles, 1975; Salsuginus fundulus of Dechtiar and Christie (1988) and of ; Urocleidus angularis Mueller, 1934; Urocleidus fundulus of Hanek and Fernando (1972), and of Cone (1980)). …”
