Abstract
Echinorhynchus trachyrinci n. sp. (Palaeacanthocephala: Echinorhynchid ae) is described from Trachyrincus scabrus (Rafinesque) (Macrouridae: Trachyrincinae) (type-host) and T. murrayi Gunther from the northeast Atlantic. The most important diagnostic features of this species are: the number of longitudinal rows of hooks 17-22; the number of hooks pe r row 17-22+; the maximum length of hook blade 38-52 mu m; the probosc is width 139-224 mu m; and the proboscis length to width ratio 3.9-6.4 :1. E. trachyrinci n. sp. is differentiated from E. gadi, E. malacocep hali, E. longiproboscis, E. petrotschenkoi, E. melanoglaeae, E. therag rae and E. sebastolobi. Metechinorhynchus malacocephali Parukhin, 1985 is transferred to Echinorhynchus as E. malacocephali n. comb.
