Examination of type material of two species ofLitomosoides(Filarioidea : Onchocercidae), parasites from bats ; taxonomic consequences

Litomosoides (Nemata: Filarioidea) of Bats from Bolivia with Records for Three Known Species and the Description of a New Species

“…Litomosoides salazari differs from L. brasiliensis in having a simple shape of the heel of the right spicule, the vulva being very near the esophago-intestinal junction, and by the inconspicuous ventral cephalic papillae (Guerrero et al, 2002). It also differs from L. yutajensis in the absence of a bell-like-shaped buccal capsule, and a longer and slender microfilaria instead of a stout microfilaria (length 58 vs. 75 mm, width 4.3 vs. 3.3 mm; see Guerrero et al, 2003). The new species also differs from L. guiterasi (Perez Vigueras, 1934), a parasite of Artibeus jamaicensis parvipes Rehn 1902 from Cuba, in the shape of the buccal capsule and the head papillae.…”

“…The females of the new species can be recognized as distinct from those of L. artibei Esslinger, 1973 in having a shorter buccal capsule and a vulva very near the esophago-intestinal junction (Esslinger, 1973). The new species is different from L. chitwoodi Bain, Guerrero, and Rodriguez, 2003 in having a longer buccal capsule and a more anterior vulva (Chitwood, 1938;Bain et al, 2003). The microfilariae of L. salazari are shorter than those described from L. colombiensis Esslinger, 1973 [a parasite of Platyrrhinus dorsalis (Thomas, 1900)-mentioned as Vampyrops dorsalis-and A. jamaicensis Leach, 1821 from Colombia] and lacks any nuclei in the tail in contrast to those of L. colombiensis, which has a single row of nuclei in the tail (see Esslinger, 1973).…”

“…The new species is smaller than L. hamletti, L. brasiliensis, and L. yutajensis Guerrero, Martin and Bain, 2003. In addition, the walls of the buccal capsule of L. hamletti are narrower (Jiménez-Quiró s and Arroyo, 1960; Guerrero et al, 2002;Bain et al, 2003), and the tail of the male is shorter (mean of 64 vs. 80.2 mm). Litomosoides salazari differs from L. brasiliensis in having a simple shape of the heel of the right spicule, the vulva being very near the esophago-intestinal junction, and by the inconspicuous ventral cephalic papillae (Guerrero et al, 2002).…”

“…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.…”

Litomosoides silvai (Nematoda: Onchocercidae) parasitizing Akodon montensis (Rodentia: Cricetidae) in the southern region of Brazil

“…Currently, this genus is represented by 43 known species (NOTARNICOLA et al, 2012;NOTARNICOLA & de la SANCHA, 2015;OVIEDO et al, 2016). In Brazil, species of Litomosoides have been found parasitizing marsupials (BAIN et al, 1980;MULLER, 1980), bats (LINS DE ALMEIDA, 1936apud NOTARNICOLA et al, 2010REGO, 1961;GUERRERO et al, 2002;BAIN et al, 2003) and rodents (TRAVASSOS, 1919apud PADILHA & FARIA, 1977PADILHA & FARIA, 1977;BAIN et al, 1989;SIMÕES et al, 2012). Two species, Litomosoides silvai (PADILHA & FARIA, 1977) and Litomosoides chagasfilhoi have been recorded in the rodent Akodon cursor Winge, 1887, in Itaguaí and Rio Bonito, in the Atlantic Forest region of the state of Rio de Janeiro (PADILHA & FARIA, 1977;MORAES-NETO et al, 1996SIMÕES et al, 2011SIMÕES et al, , 2012.…”
