“…Some males and females presented longer buccal capsules (35 and 40, respectively), and most of the males examined had an adcloacal pair of papillae and 1 pair of asymmetric post-cloacal papillae. This subspecies has been reported from G. soricina from Brazil, Mexico, Colombia, and Venezuela (Sandground, 1934;Chitwood, 1938;Rego, 1961;Esslinger, 1973;Guerrero et al, 2002). It represents the first record for the species in Bolivia.…”

“…After re-examination of the type material, Bain et al (2003) suggested 2 subspecies for L. hamletti, i.e., Litomosoides hamletti hamletti to include the specimens of Sandground (1934), Rego (1961), Esslinger (1973), and Guerrero et al (2002)-mentioned as L. guiterasi-and L. hamletti penai to include the specimens of Jiménez-Quiró s and Arroyo (1960)-mentioned as L. penai. The justification is that because females of the latter subspecies are longer, the vulva is located posterior to the esophagointestinal junction, and the tail is more attenuated.…”

“…: L. guiterasi (Vigueras, 1934), L. molossi Esslinger, 1973, and L. chandleri Esslinger, 1973 are smaller species, with shorter spicules and microfilariae displaying the last nucleus at the tip of tail (Vigueras, 1934;Esslinger, 1973). Moreover, from the re-descriptions by Sandground (1934), Rego (1961), and Esslinger (1973), L. guiterasi has a shorter tail in both sexes, a truncated extremity in female worms, and vulva at the level of the esophagus. Litomosoides molossi has a shorter buccal capsule, no cloacal papillae in the male, and a thinner microfilaria (mean of 3 vs. 4.7).…”

A new species of Litomosoides was collected from the abdominal cavity of Oligoryzomys nigripes (Rodentia: Muridae) in a semideciduous secondary rainforest of Misiones, Argentina. Litomosoides odilae n. sp. belongs to the carinii group and is characterized by the amphids displaced dorsally; buccal capsule with an anterior segment transparent and an annular asymmetrical thickening; esophagus divided, with the posterior glandular portion slightly wider than the muscular; male cloacal aperture strongly protruded; and microfilaria sheathed with an attenuated tail. The morphology of the new species, which is similar to that of L petteri, a parasite of marsupials in Brazil, suggests that host-switching events may have occurred in the diversification of this genus.

“…in Brasil, was subsequently assigned to specimens from diverse microchiropterans from South American geographic areas. However the redescriptions (Rego, 1961; Diaz-Ungria, 1963; Esslinger, 1973; Guerrero et al , 2002) were not all similar, particularly in the morphology of the buccal capsule and, when studied in ventral view, the arrangement of caudal papillae (Diaz-Ungria, 1963; Guerrero et al , 2002). Consequently, Guerrero et al (2002) suggested that the taxon L. brasiliensis was very likely a complex of species and they prefered not to place L. brasiliensis in synonymy with the oldest taxon, L. serpicula .…”

Parasitic nematodes from the Berlin (ZMB) and Vienna (NMW) Museum collections referred to the genus Filaria Mueller, 1787 by von Linstow or Molin were studied. Three samples were in good condition and the specimens redescribed. Litomosa hepatica (von Linstow, 1897) n. comb., sample ZMB Vermes Entozoa 3368, from the megachiropteran Pteropus neohibernicus, Bismarck Archipelago, resembles L. maki Tibayrenc, Bain & Ramanchandran, 1979, from Pteropus vampyrus, in Malaysia, but the buccal capsule differs. Both species display particular morphological characters which differ from species of Litomosa parasitic in microchiropterans. The remaining material originates from Brazil. The spicule morphology of Litomosoides circularis (von Linstow, 1899) Chandler, 1931, sample ZMB Vermes Entozoa 1059 from Hesperomys spec. (= Holochilus brasiliensis), Porto Alegre, confirms that it belongs to the sigmodontis group; the microfilaria presents characters of the genus Litomosoides, e.g. body attenuated at both extremities and salient cephalic hook. Taxonomic discussions by others confirm that species of Litomosoides belonging to the sigmodontis group and described subsequently are distinct from L. circularis. Litomosoides serpicula (Molin, 1858) Guerrero, Martin, Gardner & Bain, 2002, is redescribed, sample NMW 6323 from the bat Phyllostoma spiculatum (= Sturnira lilium), Ypanema. It is very close to L. brasiliensis Almeida, 1936, type host Moytis sp., but distinguished by a single ring in the buccal capsule, rather than two, supporting previous conclusions that the taxon L. brasiliensis, as generally regarded, may represent a complex of species. Samples NMW 6322 and NMW 6324, from other bats and also identified by Molin (1858) as Filaria serpicula, contain unidentifiable fragments of Litomosoides incertae sedis. Filaria hyalina von Linstow, 1890, sample ZMB Vermes Entozoa Q 3905 from Sorex vulgaris (= Sorex araneus), is incertae sedis because it contains two unidentifiable posterior parts of male, which might be an acuarid, Stammerinema sp. Filaria vesperuginis von Linstow, 1885, sample ZMB Vermes Entozoa Q 3929, from the bat Vesperugo serotinus (= Eptesicus serotinus), contains encysted nematode larvae and is a nomen dubium.
