Zoogeography And Host-Specificity Of The Superfamily Capsaloidea Price, 1936 (Monogenea, Monopisthocotylea) : An Evaluation Of The Host-Parasite Locality Records Of The Superfamily Capsaloidea Price, 1936, And Their Utility In Determinations Of Host-Specificity And Zoogeography, Adrian R. Lawler
Reports
Original literature on the super family Capsaloidea Price, 1936 published prior to May 1968 was examined for parasite-host locality records in order to study the host-specificity and zoogeography of the super family. Complete locality records, synonyms, and references for 221 species of capsaloids belonging to 70 genera and five families and parasitizing over 260 natural hosts are given. New locality records are given for Dioncus agassizi, D. remora, and Caballerocotyla manteri. Host-specificity tables are given f or all species. The host names have been updated, and the host ranges documented. Comments are made on conf used and elroneous records. The …
Morphology Of Udonella Caligorum Johnston, 1835, And The Position Of Udonellidae In The Systematics Of Platyhelminths, A. V. Ivanov
Morphology Of Udonella Caligorum Johnston, 1835, And The Position Of Udonellidae In The Systematics Of Platyhelminths, A. V. Ivanov
Reports
The platyhelminth, Udonella, lives on parasitic copepod crustaceans and, according to the present system of classification belongs to monogenetic trematodes (Monogena) among which it is usually placed in the group Monopisthocotylea (Fuhrmann, 1928; Bychowsky, 1937; Dawes, 1946; Sproston, 1946). However, the morphology of Udonella has not yet been studied thoroughly by anyone, and a number of unusual features of the structure, ontogenesis and biology of this form cause doubts with regard to its belonging to the Monogena.
Ontogenesis And Phylogenetic Interrelationships Of Parasitic Flatworms, Boris E. Bychowsky
Ontogenesis And Phylogenetic Interrelationships Of Parasitic Flatworms, Boris E. Bychowsky
Reports
The purpose of this report is to establish relationship among individual groups of parasitic flatworms, namely, among monogenetic trematodes (Monogenea), digenetic trematodes (Digenea), tapeworms proper (Cestoda), and the so-called Cestodaria group (AMPHILINIDAE and GYROCGTYLIDAE). The attempt to establish the above-mentioned relationships is made to a variable degree for different groups. The main point of this report is the establishment of phylogenetic relationship in the Monogenea, not only for the entire group as a whole, but also for the individual families which are members of this group. We feel that another important point is our attempt at clarifying the phylogenetic position …
