Another New Species of Free-Living Marine Nematode (Nematoda: Enoplida) from Northwest Florida, U.S.A.
Transactions of the American Microscopical Society
Enoplolaimus asymmetricus n. sp. is described from subtidal non-vegetated sediments from St. Andrew Bay, Bay County, Florida. E. asymmetricus n. sp. has a distinct sexual dimorphism in the shape of the mandibles and position of the mouth and labial setae. The new species is most similar to Enoplolaimus punctatus, which is the only other species in the genus with a striated and punctate cuticle. Males of E. asymmetricus n. sp. differ from males of E. punctatus in the shape and asymmetry of the mandibles, in the position of the mouth and labial setae, in the absence of a gubernaculum, in the shape of the spicules, and in the presence of a pair of subventral post-anal sensillae. Females of E.asymmetricus n. sp. are difficult to differentiate from females of E. punctatus, except for differences in the relative lengths of the cephalic setae.
