“…Deirids are very small and difficult to find in Dracunculus spp. and they have rarely been reported in these nematodes (e.g., Brackett 1938, Desportes 1938, Chabaud 1960, Vaucher and Bain 1973.…”

Abstract. Dracunculus globocephalus Mackin, 1927 (Nematoda: Dracunculoidea) is redescribed from specimens collected from the mesentery of the snapping turtle, Chelydra serpentina (L.), in Louisiana, USA. The use of scanning electron microscopy, applied for the first time in this species, made it possible to study details in the structure of the cephalic end and the arrangement of male caudal papillae that are difficult to observe under the light microscope. This species markedly differs from all other species of Dracunculus in having the spicules greatly unequal in size and shape, in the absence of a gubernaculum, and in the disposition of male caudal papillae. The validity of D. globocephalus is confirmed, but the above mentioned morphological differences are not sufficient for listing it in a separate genus. This is the first record of D. globocephalus in Louisiana.

“…A characteristic feature of some, perhaps all, of these species is the way inwhich the worm is situated in the wall of the stomach. In the description of O. trichuriformis by Vaz (1935), O. solenopoion by Chabaud (1960) and O. "labiatopapillosa" by Ash and Beaver (1963), it was stated that the worms are associated with the wall of the stomach in such a way that the anterior and posterior ends are free and the middle part embedded.…”

“…"labiatopapillosa" by Ash and Beaver (1963), it was stated that the worms are associated with the wall of the stomach in such a way that the anterior and posterior ends are free and the middle part embedded. Chabaud (1960) suggested that the narrowing of the middle part of the body of O. mombasica mentioned by Baylis (1921) was caused by its being embedded in the same way. This feature is also characteristic of O. pyrrhus in Australian elapids (Fig.…”

The genus Ophidascaris is revised and divided into five groups of species. A key for the species groups is provided. Group 1 (' filaria' group) occurs in pythons and a key is provided for differentiating eight species based on fresh and preserved specimens and on developmental patterns. 0. papillifera (Linstow, 1898) is redescribed from the type-specimens and is considered to be close or identical to 0. niuginiensis, for which Candoia carinatus is recorded as a new host. A key for the differentiation of species in Groups 2 to 5 is based on preserved specimens only. Group 2 (' obconica' group) contains (i) 0. obconica and 0. trichuriformis [ = caballeroi] in South American colubrids (further investigation will probably show that 0. trichuriformis is a synonym of 0. obconica); new host records are Xenodon severus, X. neuwiedii, X. colubrinus, Leptodeira annulata, Thamnodynastes pallidus, Leimadophis poecilogyrus and Boa constrictor; (ii)O. ashi n. sp. (new species name for ' 0. labiatopapillosa' ) in North American colubrids, new host records are Nerodia valida, Heterodon nasicus and Storeria occipitomaculata; (iii) 0. mombasica in African colubrids; new host records are Psammophis phillipsii and P. sibilans; (iv) 0. solenopoion in Madagascan colubrids; (v) 0. pyrrhus in Australian elapids; new host records are Cacophis squamulosus, Cryptophis nigrescens, Demansia atra, D. olivacea, Hemiaspis signata, Hoplocephalus bitorquatus, H. stephensi, H. bungaroides and Tropedechis carinatus, it is also recorded in Australia in the colubrid Styporhyncus mairii (new host record) and in Demansia papuensis papuensis and D. olivacea papuensis in Papua New Guinea; (vi) 0. piscatori in Asian colubrids; (vii) 0. excavata [? = schikhobalovi] in Agkistrodon spp. and possibly other aquatic snakes in Asia; new host record is Agkistrodon halys blomhoffi. Group 3 (' radiosa' group) in African viperids contains 0. radiosa [= intorta] in Bitis spp. Specimens from Atheris nitschei, Causus rhombeatus and the colubrid Boaedon lineatus were similar, but showed differences indicating possibility of other species in this group. Group 4 (' najae' group) in African elapids and Asian elapids and colubrids contains 0. najae [ = daubaylisi]; new host records are Ophiophagus hannah, Boiga cyanea, Elaphe carinata. Group 5 (' arndti' group) in South American crotalids and colubrids contains 0. arndti [ = travassosi and sprenti] in Crotalus spp. and Bothrops spp.; new host record is B. atrox in Panama. No morphological differentiation except size could be detected between 0. arndti in crotalines and 0. sicki in colubrids, but in view of difference in the feeding habits of their host, both species names were tentatively sustained; new host records for 0. sicki are Xenodon neuwiedii, Leimadophis poecilogyrus, Pseudoboa cloelia, Philodryas patagoniensis and Micrurus frontalis; 0. ochoteranai was regarded as a species inquirenda.

“…To our knowledge, there are no reports of helminths from L. darlingtoni. Species of Maxvachonia Chabaud et Brygoo, 1960 occur in the digestive tracts of amphibians and reptiles. Of the 6 nominal species, 5 are known from the Australo-Papuan Region (Moravec and Sey 1990).…”

“…A comparison of the species of Maxvachonia is given in Table I. The type species, M. dimorpha Chabaud et Brygoo, 1960 was originally described from a lizard, Furcifer (= Chamaeleo) pardalis collected in Madagascar (Chabaud and Brygoo 1960); a host list was published by Goldberg and Bursey (2004). The five other species, M. adamsoni Moravec et Sey, 1990, M. brygooi Mawson, 1972, M. chabaudi Mawson, 1972, M. ewersi Mawson, 1972and M. flindersi (Johnston et Mawson, 1941 Mawson, 1972 are parasites of anurans and reptiles in the Australo-Papuan Region.…”

Maxvachonia ingens sp. nov. (Nematoda, Cosmocercidae) in Litoria darlingtoni (Anura, Hylidae) from Papua New Guinea

Maxvachonia ingens sp. nov. from the intestines of Litoria darlingtoni (Hylidae) from Papua New Guinea is described and illustrated. Maxvachonia ingens sp. nov. represents the 7th species assigned to the genus and the 5th from the Australo-Papuan Region. The new species differs from other species assigned to Maxvachonia by the position of the vulva in the female (the only species with a post-oesophageal position) and the spicule/gubernaculum ratio of the male (the only species with ratio greater than 1). Females of the new species are most similar to M. dimorpha and M. ewersi in that the posterior ends of these three species are rounded. These species are easily separated: M. ewersi possesses lateral alae, the other 2 do not; the posterior end of M. dimorpha terminates in a mucro, M. ingens sp. nov. lacks terminal ornamentation.
