Morphology and Anatomy:

General characteristics of the genus:

• Small nematodes
• Cephalic vesicle present; cervical alae present, extending from the cephalic region to the mid-body in males and before the vulva in females;
• Cervical alae with two crests (sensu Hugot 1980) in cross section.
• Lateral alae are reduced in  both sexes.
• Mouth is surrounded by six lips, one pair of lateral "epaulettes" with two amphids and four labial papillae.

Males:

• Males are shorter than females.
• A ventral ala is present in males, from mid-body region to before the cloaca.
• No caudal alae.
• Gubernaculum and spicules are absent.
• Ten caudal papillae are arranged as follows: one pair precloacal, one pair adcloacal, a single median postcloacal papilla closely associated with the cloaca, one posterior pair followed by one single median papilla, and one additional posterior pair.

Distribution:

Describerd as a parasite of Neotoma nelsoni (Rodentia) in Veracruz, Mexico. Neotoma nelsoni is distributed from southeastern California and southeastern Utah to central Texas and from northeastern Michoacán to Hidalgo, Mexico . Other woodrat species, which are also hosts, occur throughout western North America (Falcon-Ordaz et al., 2010).

The type host is N. albigla from which Aspiculuris ackerti was described b Kruidenier and Mahra (1959)
