THE SNAKES of SURINAM, PART XVI: SUBFAMILY XENO- By: A
-THE SNAKES -OF SURINAM, ---PART XVI: SUBFAMILY --XENO- DONTINAE ( GENERA WAGLEROPHIS., XENODON AND XENO PHOLIS). By: A. Abuys, Jukwerderweg 31, 9901 GL Appinge dam, The Netherlands. Contents: The genus WagZerophis - The genus Xeno don - The genus XenophoZis - References. THE GENUS wAGLEROPHIS ROMANO & HOGE, 1972 This genus contains only one species. Prior to 1972 this species was known as Xenodon merremii (Wagler, 1824). This species is found in Surinam. General data for the genus: Head: The head is short and slightly flattened. The strong neck is only marginally narrower than the head. The relatively large eyes have round pupils. Body: Short and stout with smooth scales. The scales have one apical groove. The formation of the dorsal scales is characteristic for this genus. These are arranged so that the upper rows are at an angle to the lower ones (see figure 1) . Tail: Short. Behaviour: Terrestrial and both nocturnal and di urnal. Food: Frogs, toads, lizards and sometimes snakes, insects or small mammals. Habitat: Damp forest floors near swamps or water. Reproduction: Oviparous. Remarks: When threatened or disturbed, the fore part of the body is inflated and the neck is spread in a cobra-like fashion. The head is al· so raised slightly, but not as high and as 181 Fig. 1. Dorsal scale pattern of Waglerophis. From: Peters & Orejas-Miranda, 1970. vertically as a cobra. This is an aggressive snake which will invariably resort to biting if the warning behaviour described above is not heeded. This genus (in common with the genera Xenodon, Heterodon and Lystrophis) has two enlarged teeth attached to the back of the upper jaw. -

KUZNETSOV; e-mail: [email protected] ABSTRACT. The review provides data on species composition of nematodes in 50 species of birds from Armenia (South of Lesser Caucasus). Most of the studied birds belong to Passeriformes and Charadriiformes orders. One of the studied species of birds (Larus armenicus) is an endemic. The taxonomy and host-specificity of nematodes reported in original papers are discussed with a regard to current knowledge about this point. In total, 52 nematode species parasitizing birds in Armenia are reported. Most of the reported species of nematodes are quite common in birds outside of Armenia. One species (Desmidocercella incognita from great cormorant) was first identified in Armenia. -
Notes on the Paradox Frog, Pseudis Paradoxa, in Bolivia
British Herpetological Society Bullton. No. 68. 1999 NOTES ON THE PARADOX FROG, PSEUDIS PARADOXA, IN BOLIVIA IGNACIO DE LA RIVA Department of Biodiversity and Evolutionary Biology Museo Nacional de Ciencias Naturales a Jose Gutierrez Abascal 2, 28006 Madrid, Spain INTRODUCTION The South American Paradox Frog, Pseudis paradoxa (Plate. 1) is primarily a dweller of open, lowland areas, where it inhabits marshes, ponds and other types of lentic water bodies. It has a discontinuous distribution from Colombia to Argentina. Inter- populational differences primarily in colour pattern, as well a in some other features, have led to the recognition of seven subspecies [P. p. bolbodactyla and P. p. fusca were recently proposed to be elevated to specific status (Caramaschi and Cruz, 1998)]. DISTRIBUTION AND SUBSPECIES IN BOLIVIA For taxonomic and biogeographical reasons, the lowlands of Bolivia are an interesting area with respect to this frog. The distribution of the species in this country is poorly known. The first Bolivian record of P. paradoxa was provided by Muller and Hellmich (1936) at San Fermiin, Department of Santa Cruz. Since then, it was reported at some other localities, mostly in the Department of Santa Cruz [see De la Riva (1990) and below]. It was interesting that it was also discovered at two localities in southeastern Peru (Duellman and Salas, 1991; Henle, 1992). These discoveries made plausible that it ranges throughout the intermediate area of extensive, suitable habitat of humid savannas in the Bolivian Department of Beni. However, there is a surprising scarcity of published records for this huge and relatively (by Bolivian standards) well surveyed zone. -

It differs from tadpoles of other species of Sphaenorhynchus in having a short spiracle, submarginal papillae, and alternating short and large marginal papillae in the oral disc. Some larval characteristics, like morphology and position of the nostrils, length of the spiracle, and size of the marginal papillae on the oral disc are discussed for tadpoles of other species of Sphaenorhynchus.

There is, however, presently no study conducted on the endoparasites infestation in these fishes. Therefore, the objectives of the present study were to identify endoparasitic worms and examine the intensity level in skipjack tuna K. pelamis from Sibolga waters. Sampling was conducted in Debora Private Fishing Port, Sibolga from 4th to 18th June 2019 and a total of 20 fish samples with weight ranged between 740 g and 1.200 g and length from 37.2 cm to 41.4 cm were analyzed in the study. The identification of the worm was conducted in the laboratory using a stereo microscope. The results showed seven species or genera of worms were found in the intestine and stomach of the fish with varying level of intensity and incidence. For example, Echinorhynchus sp. was found with 100% intestinal and 10% stomach incidences at a total intensity of 8.5; Acanthocephalus sp. with 25% intestinal incidence and 1.6 intensity, Rhadinorhynchus sp. with 25% intestinal and 5% stomach incidences, and 1.5 intensity; Leptorhynchoides sp. -

Although some studies have addressed the phylogenetic relationships of the genus with other hylids using a few exemplar species, its internal relationships remain poorly understood. In order to test its monophyly and the relationships among its species, we performed a total evidence phylogenetic analysis of sequences of three mitochondrial and three nuclear genes, and 193 phenotypic characters from all species of Sphaenorhynchus. -
(Nematoda: Habronematidae) from the Burchelps Zebras and Hartmann's Mountain Zebras in Southern Africa
Proc. Helminthol. Soc. Wash. 56(2), 1989, pp. 183-191 Habronema malani sp. n. and Habronema tomasi sp. n. (Nematoda: Habronematidae) from the BurchelPs Zebras and Hartmann's Mountain Zebras in Southern Africa ROSINA C. KRECEK Department of Parasitology, Faculty of Veterinary Science, University of Pretoria, Private Bag X04, Onderstepoort 0110, South Africa ABSTRACT: Habronema malani sp. n. is described from the stomachs of 44 Burchell's zebras, Equus burchelli antiquorum, in the Etosha and Kruger national parks and 6 Hartmann's mountain zebras, Equus zebra hart- mannae, from the Etosha National Park in southern Africa. Habronema tomasi sp. n. is described from the small intestines of 35 Burchell's zebras in the Kruger National Park. Habronema malani is distinguished from other members of the genus by its deep buccal capsule with walls that are narrower anteriorly than posteriorly and have projections in the anterior end; spicule length ratio (right:left) ranging 1:2.3 to 1:3.7; a short, stout, and striated right spicule; and a long and slender left spicule with a pointed projection. Habronema tomasi is differentiated from the other species by buccal capsule walls that are wider anteriorly than posteriorly; a distance between the anterior wall of the buccal capsule and the inner surface of the lateral lips that is almost equal to the buccal capsule depth; an ovejector with spiral-shaped muscles; and a spicule length ratio (right: left) ranging 1:1.5 to 1:2.95. The right spicule of//, tomasi is short and cross striated except at the distal fourth where the tip is flanged. -

In the present study, five roadkilled oncillas Leopardus( tigrinus Schreber, 1775) were collected in the State of Rio Grande do Sul, Brazil. Chronic lesions caused by O. pardalis were observed in the small intestine of one of the specimens. Histological examination identified a well-defined leukocyte infiltration and an area of collagenous fibrosis. Only males parasites (n = 5) were found, with a prevalence of 20%. The life cycle of Oligacanthorhynchus species is poorly known, although arthropods may be their intermediate hosts. The low prevalence encountered may be related to the small number of hosts examined, and the reduced ingestion of arthropods infected by larvae of O. pardalis. This is the first report ofO. pardalis parasitizing L. tigrinus in the Brazilian state of Rio Grande do Sul. Keywords: Oncilla, Oligacanthorhynchus, lesions, Neotropical Region.
