Les fondements de la taxonomie des Strigeata La Rue (Trematoda: Strigeida)

Abstract

Dans cette Synopsis, les Cyathocotylinae et les Braunininae s'opposent aux autres sous-familles par la possession d'une poche du cirre. Les Strigeinae sont caractérisés par leur segment antérieur cupuliforme, contenant un « holdfast organ variously developed but always prominent ». La grande sous-famille des Polyeotxlinae réunit des parasites d'Oiseaux et de Reptiles, tandis que celle des Alariinae groupe ceux de Mammifères. La première s'oppose à la seconde par la forme de l'organe adhésif: « usually circular, bulbous or short elliptical, with a cavity » d'une part, « greatly elongated or cordate » d'autre paît. Proalaria diffère de Neodiplostomum par la possession de « lateral suctorial cups or earlike appendages », et tous deux se distinguent d' 'Alaria par la distribution des follicules Dubois, Georges. 1970.

Molecular phylogenetic analysis of Neodiplostomum and Fibricola (Digenea, Diplostomidae) does not support host-based systematics

“…Despite similarities in larval and adult morphology, Dubois (1970) rejected the placement of Fibricola as a subgenus of Neodiplostomum and insisted that the distribution of vitellarium and specificity to mammals were sufficient for separation between the two genera. In spite of his own statement, Dubois (1983) placed N. vaucheri collected from a chiropteran host into Neodiplostomum .…”

Unravelling the diversity of the Crassiphialinae (Digenea: Diplostomidae) with molecular phylogeny and descriptions of five new species

“…Its members parasitize, as adults, a variety of avian and mammalian definitive hosts worldwide. Despite the large number of studies on the Crassiphialinae, the systematics of the subfamily is complex and has always been unstable ( Dubois, 1970 ; Shoop, 1989 ; Niewiadomska, 2002 ). Therefore, the use of DNA sequence data for phylogenetic inference and taxon differentiation within the Crassiphialinae is highly beneficial.…”

Validity of the Diplostomoidea and Diplostomida (Digenea, Platyhelminthes) upheld in phylogenomic analysis

“…As life cycles became better known, Cort (1917), Stunkard (1946) and others increasingly emphasized other characters, particularly cercarial morphology. Using a variety of methods, different authors produced conflicting hypotheses and higher classifications, but many concluded a close relationship exists among members of the Diplostomoidea Poirier, 1886, the Clinostomatoidea Lühe, 1901, and the Schistosomatoidea Stiles and Hassall, 1898 (Brooks et al, 1985;Dubois, 1970a;Gibson, 1996;La Rue, 1957;Pearson, 1972). Most authors assigned these and other superfamilies to the Strigeida (=Strigeatoidea) La Rue 1957, which are characterized by furcocercous cercariae that penetrate hosts (Gibson and Bray, 1994).…”
