First record of Mastophorus muris (Gmelin, 1790) (Nematoda: Spiruroidea) from a wild host in South America.

Mastophorus muris (Gmelin, 1790) (Nematoda: Spiruroidea) is reported parasitizing the grey leaf-eared mouse Graomys griseoflavus (Waterhouse, 1837) (Rodentia: Sigmodontinae) from the province of La Pampa, Argentina. The distinct position of Mastophorus (Spirocercidae: Mastophorinae) and Protospirura (Spiruridae), sometimes still confused, is again confirmed. The pattern of pseudolabial teeth (a large central tooth with smaller teeth on each side), which seems to be rather stable in all known descriptions, is here confirmed with the aid of scanning electron microscopy. The finding represents the first record of the species in Argentina, but also from a wild host in South America. This indicates an expansion of the distribution range of the species, which, in the subcontinent, was hitherto restricted to domestic rodents.

Larval nematodes (Spiruroidea: Cystidicolidae) in Octopus vulgaris (Mollusca: Cephalopoda: Octopodidae) from the northeastern Atlantic Ocean.

Larval nematode parasites (Spiruroidea: Cystidicolidae) are recorded for the first time in Octopus vulgaris Cuvier, 1797 in the northeastern Atlantic Ocean. Prevalence was 16% and mean intensity was 1.46 worms/host. Body length of larval nematodes ranges from 8.3 to 9.3 mm, with a distance from the anterior end to nerve ring from 187.5 to 200 microm, and to excretory pore 194.6-350 microm. Anatomical characteristics, such as deirid, nerve ring, cephalic alae, excretory pore, pseudolabia amphids, sclerotized protuberance, and anus, examined using light microscopy (LM) or scanning electron microscopy (SEM), are illustrated. The nematode was designed as a cystidicolid "Type A" larva. The hemocytic infiltration present in the host tissue around the nematode capsule and the mechanical compression in the infected organs denote the pathogenicity of this nematode. In the study area, O. vulgaris may play the role of an intermediate or paratenic host in the nematode life cycle.

Unusual finding of encapsulated nematode larvae (Spiruroidea) in Bartramia longicauda and Numenius americanus (Charadriiformes) in western Canada.

Third-stage spiruroid larvae were found encapsulated on the serosa of the small and large intestines and in the mesentery of one of 15 adult upland sandpipers (Bartramia longicauda) from Manitoba, Canada, and three of 18 adult long-billed curlews (Numenius americanus) from Alberta, Canada. The larvae resemble third-stage larvae of Physocephalus sexalatus and birds may serve as a paratenic host of this unidentified spiruroid species.

Development of third-stage Physaloptera larvae from Crotalus viridis rafinesque, 1818 in cats with notes on pathology of the larvae in the reptile. (Nematoda, Spiruroidea).

The prairie rattlesnake, Crotalus viridis, was found to be commonly infected with third-stage Physaloptera larvae. A total of 112 larvae were fed to 3 laboratory raised cats. Adult worms recovered 42 and 59 days postinfection were identified as P. rara. Observations were made on the pathology of the larvae in the snake.

Rhabdochona minima sp. n. (Nematoda: Spiruroidea) from the loach, Noemacheilus inglisi (Hora), of Nepal.

A new nematode species, Rhabdochona minima sp.n., is described from the intestine of Noemacheilus inglisi (HORA) OF Nepal (River Ganges drainage system). Characteristics features of this species (only males were found) are the small size of body, size and type of spicules, shape of tail and arrangement of caudal papillae. On the basis of its morphology, R. minima sp.n. belongs to the subgenus Globochona sensu Moravec, 1975. The species Rhabdochona cavasius Rehana et Bilqees, 1973 is considered to be a synonym of R. mazedi Prassad et Sahay, 1965.
