Echinoparyphium speotyto sp. n. (Trematoda: Echinostomatidae) from the Burrowing Owl in Oklahoma, with a Discussion of the Genus Echinoparyphium

Helminths of rodents and marsupials from Papua New Guinea, with the description of two new species, Echinostoma echymiperae n. sp. (Digenea: Echinostomatidae) and Vampirolepis peroryctis n. sp. (Cestoda: Hymenolepididae)

“…As the genera are currently defined, the present specimens are excluded from Euparyphiurn and Echinoparyphium by possession of a long uterus containing numerous eggs. In addition, Buscher (1978) defined Echinoparyphium as having dorsal collar spines in the aboral row considerably larger than those in the oral row, which is not the case in the present specimens. As currently defined and composed, Echinostoma accommodates the characteristics of the present specimens.…”

“…Allocation of the specimens to a genus within the Echinostomatinae is not straightforward, reflecting the current confusion in the taxonomy of the group. They are nearest to Euparyphium Dietz, 1909, Echinoparyphium Dietz, 1909and Echinostoma Rudolphi, 1809 and, on the basis of the generic diagnoses provided by Skrjabin (1956), Yamaguti (1971) and Buscher (1978), have been provisionally allocated to Echinostoma, although it is recognised that this might change as a result of future revisions. As the genera are currently defined, the present specimens are excluded from Euparyphiurn and Echinoparyphium by possession of a long uterus containing numerous eggs.…”

“…E. emollitum Nicoll, 1914 from Centropus phasianus has 35 collar spines which are smaller than those of the new species: it has a small delicate body and also differs in body spination, the relative positions of the gonads and the distribution of the vitelline follicles. Both E. australasianum and E. emollitum have been transferred to Echinoparyphium Dietz, 1909 by Mendheim (1943) and Baschkirova (1947), respectively, but were restored by Buscher (1978). E. bancrofti Johnston, 1928 from Gallinula terebrosa, redescribed by Macko (1971) from Fulica atra in Czechoslovakia, has 45-51 (usually 47) collar spines in a single row.…”

Echinoparyphium elegans (Looss, 1899) (Digenea: Echinostomatidae): the life cycle and redescription of the adult with a revision of the 43-spined members of the genusEchinoparyphium

“…The systematic position of these species has been revised and discussed by several authors, such as Mendheim (1943), Bashkirova (1947), Dollfus (1953), Skrjabin & Bashkirova (1956), Buscher (1978) and Bychovskaja-Pavlovskaja (1978). These revisions have resulted in a reduction of the representative number of species within the genus.…”

“…2) Buscher (1978) propose une formule pour traduire la disposition des épines du collet des Echinoparyphium ; si on l'applique à nos exemplaires l'arrangement de leurs épines peut se formuler de la façon suivante : 5-5-3-3-27 (14-13). Le tégument présente une spinulation antérieure qui s'étend dorsalement jus qu'au niveau de la bifurcation caecale et ventralement jusqu'au niveau du deuxième tiers de l 'acétabulum.…”
