Spirurides Parasites d’Oiseaux malgaches

Paraspiralatus sakeri n. g., n. sp. (Nematoda: Spiruroidea, Spirocercidae) from saker falcons, Falco cherrug in Saudi Arabia and the first report of larvae from the subcutaneous tissues of houbara bustards, Chlamydotis undulata macqueeni in Pakistan

“…Pharyngeo-intestinal valve projects into the intestine. Chabaud et al (1963) established the genus Spiralatus for a single species S. baeri from Leptosomus discolor in Madagascar on the basis of a mouth without median lobes, an oval buccal capsule with six teeth on the under rim of the lips, a long pharynx clearly divided into muscular and glandular regions, large cervical papillae positioned near the anterior end, the presence of large lateral alae, the vulva opening in the middle of the body, the female tail with a spinous tip, the females being viviparous, the male tail with large caudal alae, caudal papillae arranged in a typical primitive spirurid format, the presence of unequal spicules and a gubernaculum. These features, coupled with the specimens having been recovered from an avian host and not a mammalian host, separated the genus from other members of the subfamily Spirurinae, the subfamily to which the genus was considered to correspond.…”

“…(Nematoda: Spiruroidea, Spirocercidae) from saker falcons, Falco cherrug in Saudi Arabia and the first report of larvae from the subcutaneous tissues of houbara bustards, Chlamydotis undulata macqueeni in Pakistan A new nematode genus and species, Paraspiralatus sakeri , is described from the stomach of a wild-caught, female saker falcon in Saudi Arabia. This spirurid differs from the nearest genus and species Spiralatus baeri Chabaud, Brygoo & Durette, 1963 in the shape of the pseudolabia, shape of the buccal capsule and absence of a large cephalic vesicle. In addition, third stage spirurid larvae were recovered for the first time from subcutaneous tissues of two houbara bustards.…”

“…An additional male and female were recovered from another adult female saker falcon during a routine gastric lavage at the Center to retrieve a lead pellet from the gizzard. The specimens were compared to other spirurid nematodes from birds and were found to share some similarities to the species Spiralatus baeri Chabaud, Brygoo & Durette, 1963 from Leptosomus discolor in Madagascar. Differences in the cephalic region and buccal capsule from Spiralatus…”

Data on the morphology of Viguiera dicrurusi Gupta, 1960 (Nematoda: Habronematidae) with notes on related forms

“…Scanning electron micrographs provided detailed information about the nature of pseudolabial plates, number and shape of teeth, dentate nature of striae, and the relative position of vulva, anus and phasmid opening in female. A detailed morphometrical comparison of this species with Viguiera viduae Chabaud, 1960 The genus Viguiera Seurat, 1913 now includes 20 species; of these 9 have been described from the Indian Subcontinent. The cephalic structures are important taxonomic features of this genus, and have been inadequately described in some of the Indian species, which include Viguiera dicrurusi Gupta, 1960, Viguiera bhujangai Jehan, 1972 and Viguiera adsimilisai Sood et Kalia, 1978.…”

First report ofLitomosaspp. (Nematoda: Filarioidea) from malagasy bats; review of the genus and relationships between species

“…Investigations focu-sed on lemurians, insectivores (= lipotyphlans), birds, reptiles, and frogs (as examples, Chabaud et al, 1961;Chabaud et al, 1963;Bain & Prod'hon, 1974). At that time no filaria had been reported in bats.…”
