Lamotheoxyuris ackerti n. gen., n. comb. (Nematoda:Heteroxynematidae)
parasite of Neotoma spp. (Rodentia: Muridae)
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.
Key words:
Aspiculuris
ackerti, Mexico, Nematoda, Rodentia, USA
