MetadataShow full item record
Pettiboneia sanmatiensis Orensanz originally described from Argentina, has been discovered in California and British Columbia. The new specimens are compared with the type collection and the species is redescribed. The jaw apparatus consists of seven pairs of denticle rows and is unique to the family Dorvilleidae. A new key to the genera of the Dorvilleidae is provided which includes Pettiboneia, but excludes Apophryotrocha Jumars which has been found to be a juvenile onuphid and not a dorvilleid.
