On Mediterranean and some north-eastern Atlantic Liparidae (Pisces: Scorpaeniformes) with the restoration of Eutelichthys

The hyoid arch and branchiostegal rays of Paraliparis leptochirus (Pisces: Liparidae) and of Paraliparis murieli are described for the first time. The restoration of the validity of Eutelichthys Tortonese on the basis of the presence of only five branchiostegal rays in P. leptochirus, its type species, is proposed. Paraliparis murieli has, as the other Paraliparis spp., a hyoid arch with six branchiostegal rays. The endochondral pectoral girdle of P. leptochirus, P. murieli and P. hystrix is described for the first time, and some data about the girdle of P. edwardsi are given. Differences between P. hystrix and P. murieli, described simultaneously, and between P. murieli and P. australis are established.
