Lamotheoxyuris ackerti n. gen., n. comb. (Nematoda: Heteroxynematidae) parasite of Neotoma spp. (Rodentia: Muridae)

Abstract

On the basis of the revision of the type material of Aspiculuris ackerti Kruidenier & Mehra, 1959, and new specimens collected from Neotoma nelsoni Goldman, 1905 (Rodentia: Cricetidae), in Veracruz, Mexico, we herein describe a new genus (Lamotheoxyuris n. gen.), to which A. ackerti is transferred as Lamotheoxyuris ackerti (Kruidener & Mehra, 1959) n. gen., n. comb. This new genus differs from all other genera included in Heteroxynematinae by the following main traits: 1) mouth surrounded by six lips; 2) extension of lateral alae reduced; and 3) lack of caudal alae.

Helminth parasites of some rodents (Cricetidae, Heteromyidae, and Sciuridae) from Zacatecas, Mexico

“…Cestodes were stained with Delafield's Hematoxylin and Mayer's hydrochloric carmine, and whole-mounted in Canada balsam. Taxonomic identification was conducted by comparing morphological traits using taxonomic keys and descriptions from the specialized literature (e.g., Anderson, 2000;Falcón-Ordaz, Fernández, & García-Prieto, 2010;García-Prieto, Falcón-Ordaz, Lira-Guerrero, & Mendoza-Garfias, 2008;Khalil, Jones, & Bray, 1994;Kruidenier & Peebles, 1958;Lichtenfels, 1970;Quentin, 1970Quentin, , 1973Read & Millemann, 1953;Read, 1956;Schmidt, 1986;Smith, 1954;Tiner, 1948;Yamaguti, 1961). Parasites identified were counted to obtain the infection parameters according with the definitions suggested by Bush, Lafferty, Lotz, and Shostak (1997).…”

“…ackerti, which was recovered as a single adult female and 2 larvae (found with the primordium of the vulva). The majority of helminth life cycles sampled here are unknown, however, they could be inferred based on information from the literature based upon closely related species (Anderson, 2000;Falcón-Ordaz et al, 2010;García-Prieto et al, 2008;Joyeux & Baer, 1945;Khalil et al, 1994;Kruidenier & Peebles, 1958;Lichtenfels, 1970;Quentin, 1970Quentin, , 1973Read & Millemann, 1953;Read, 1956;Schmidt, 1986;Smith, 1954;Tiner, 1948;Yamaguti, 1961) (Table 2). H. longejector from El Gordillo and Ojocaliente, T. dipodomis from Tlalticoaloya, Rauschtineria sp.…”
