Abstract: Seventeen species of Monogenea are reported from Illinois fishes. These include Actinocleidus articularis (Mizelle, 1936) Mueller, 1937. A. crinicirrus sp. nov., Cleidodiscus bedardi Mizelle, 1936, Urocleidus acuminatus (Mizelle, 1936) Mizelle &Hughes, 1938 and U. distinctus (Mizelle, 1936) Mizelle &Hughes, 1938 from Lepomis megalotis (Raf.); A. fergusoni Mizelle, 1938, and U. ferox Mueller, 1934 from L. macroehirus Raf.; U. ammacryptus Harrises and Vickery, 1970 from Etheostoma nigrum Raf.; C. brachus… Show more

On the ontogeny of the haptor and the evolution of the Monogenea

Data on the ontogeny of the posterior haptor of monogeneans were obtained from more than 150 publications and summarised. These data were plotted into diagrams showing evolutionary capacity levels based on the theory of a progressive evolution of marginal hooks, anchors and other attachment components of the posterior haptor in the Monogenea (Malmberg, 1986). 5 + 5 unhinged marginal hooks are assumed to be the most primitive monogenean haptoral condition. Thus the diagrams were founded on a 5 + 5 unhinged marginal hook evolutionary capacity level, and the evolutionary capacity levels of anchors and other haptoral attachement components were arranged according to haptoral ontogenetical sequences. In the final "plotting diagram" data on hosts, type of spermatozoa, oncomiracidial ciliation, sensilla pattern and protonephridial systems were also included. In this way a number of correlations were revealed. Thus, for example, the number of 5 + 5 marginal hooks correlates with the most primitive monogenean type of spermatozoon and with few sensillae, many ciliated cells and a simple protonephridial system in the oncomiracidium. On the basis of the reviewed data it is concluded that the ancient monogeneans with 5 + 5 unhinged marginal hooks were divided into two main lines, one retaining unhinged marginal hooks and the other evolving hinged marginal hooks. Both main lines have recent representatives at different marginal hook evolutionary capacity levels, i.e. monogeneans retaining a haptor with only marginal hooks. For the main line with hinged marginal hooks the name Articulonchoinea n. subclass is proposed. Members with 8 + 8 hinged marginal hooks only are here called Proanchorea n. superord. Monogeneans with unhinged marginal hooks only are here called Ananchorea n. superord, and three new families are erected for its recent members: Anonchohapteridae n. tam., Acolpentronidae n. tam. and Anacanthoridae n. tam. (with 7 + 7, 8 + 8 and 9 + 9 unhinged marginal hooks, respectively). Except for the families of Articulonchoinea (e.g. Acanthocotylidae, Gyrodactylidae, Tetraonchoididae) Bychowsky's (1957) division of the Monogenea into the Oligonchoinea and Polyonchoinea fits the proposed scheme, i.e. monogeneans with unhinged marginal hooks form one old group, the Oligonchoinea, which have 5 + 5 unhinged marginal hooks, and the other group form the Polyonchoinea, which (with the exception of the Hexabothriidae) has a greater number (7 + 7, 8 + 8 or 9 + 9) of unhinged marginal hooks. It is proposed that both these names, Oligonchoinea (sensu mihi) and Polyonchoinea (sensu mihi), will be retained on one side and Articulonchoinea placed on the other side, which reflects the early monogenean evolution. Except for the members of Ananchorea [Polyonchoinea], all members

Salsuginus Beverley-Burton, 1984 has been proposed for ancyrocephalid monogeneans found on North American Cyprinodontoidei (Atheriniformes). The genus is distinguished by the following characteristics: penis sclerotized, tubular, spiralling to form single coil; accessory piece with median groove to accommodate shaft of penis, distal point heavily sclerotized; dorsal and ventral hamuli similar in shape with distinct superficial and deep roots and curved blade; dorsal and ventral transverse bars bandlike, bowed posteriorly with posterior notch at extremities of each: larval hooks of similar shape and size with well-developed sickle bearing thumblike projection. Salsuginus angularis (Mueller, 1934) Beverley-Burton, 1984, the type species, is redescribed from the present material found on Fundulus diaphanus (Lesueur) in Ontario. Salsuginus umbraensis (Mizelle, 1938) n. comb., S. funudulus (Mizelle, 1940) Beverley-Burton. 1984. S. seculus (Mizelle and Arcadi, 1945) n. comb. and S. bahamianus (Hanek and Fernando, 1972) n. comb. are transferred from Urocleidus Mueller, 1934; S. spirae (Williams, 1980) n. comb. is transferred from Ancyrocephalus Creplin, 1839. Material found on F. heteroclitus taken in New Brunswick is described as S. heterocliti n. sp. Evolutionary aspects of Salsuginus spp. are briefly discussed and notes on the identification of species parasitizing Fundulus spp. are presented. Previous records of Salsuginus spp. are listed.

The genus Onchocleidus Mueller, 1936 (Monogenea: Ancyrocephalidae) is revised. Diagnostic characters for the genus include a dextral vaginal opening, a spiral filament encircling the penis, and dorsal hamuli with reduced deep roots. Haplocleidus Mueller, 1937 and Pterocleidus Mueller, 1937 are declared junior synonyms of Onchocleidus. Onchocleidus, as presently recognized, contains 24 valid species: O. ferox (Mueller, 1934) Mueller, 1936 (type species); O. acer Mueller, 1936; Onchocleidus affinis (Mueller, 1937) n.comb.; O. attenuatus (Mizelle, 1941) Beverley-Burton, 1984; Onchocleidus chaenobryttus (Mizelle and Seamster, 1939) n.comb.; O. chautauquaensis (Mueller, 1938) Murith and Beverley-Burton, 1984; O. chrysops (Mizelle and Klucka, 1953) Beverley-Burton, 1984; O. cyanellus Mizelle, 1938; O. dispar Mueller, 1936; O. distinctus Mizelle, 1936; Onchocleidus doloresae (Hargis, 1952) n.comb.; Onchocleidus flieri (Putz and Hoffman, 1966) n.comb.; Onchocleidus furcatus (Mueller, 1937) n.comb.; Onchocleidus grandis (Mizelle and Seamster, 1939) n.comb.; O. interruptus Mizelle, 1936; Onchocleidus macropterus (Harrises, 1962) n.comb.; O. mimus Mueller, 1936; Onchocleidus miniatus (Mizelle and Jaskoski, 1942) n.comb.; Onchocleidus nactus (Mayes and Johnson, 1975) n.comb.; Onchocleidus parvicirrus (Mizelle and Jaskoski, 1942) n.comb.; O. principalis Mizelle, 1936; O. similis Mueller, 1936; Onchocleidus tuberculatus (Allison and Rogers, 1970) Cloutman, 1988; and Onchocleidus variabilis (Mizelle and Cronin, 1943) n.comb. Six species (O. acuminatus Mizelle, 1936; Pterocleidus biramosus Mueller, 1937; O. helicis Mueller, 1936; O. perdix Mueller, 1937; O. spiralis Mueller, 1937; and Urocleidus wadei Seamster, 1948) are considered species inquirendae. A key to the species of Onchocleidus is included.
