- Title
Stephonyx, a new, widespread genus of lysianassoid Amphipoda.
- Authors
LOWRY, J. K.; STODDART, H. E.
- Abstract
new genus, Stephonyx, is established for six species of scavenging lysianassoid amphipods currently included in the genus Euonyx. Stephonyx is distinguished from other lysianassoid genera by a combination of characters which include the structure of the mandibular molar, the structure of the spine-teeth on maxilla 1, and a chelate gnathopod 1. Species of Euonyx are considered to be commensals of echinoderms with modified mouthparts in which the mandibular molar is lost, the lacinia mobilis is vestigial and the spine-teeth of maxilla 1 are simple and reduced in size.
