Moaciria was first described, in 1956, from the Brazilian Noronha skink, but other species from more parts of the world have since been described. Moaciria moraveci is a small but stout nematode. The male is smaller than the female. In males, total length is 2.59 to 2.85 mm, and in females, it is 2.94 to 4.16 mm.
