Zootaxa 3790(3). Would love a copy if anyone gets it.

Abstract

A new species of the trichomycterid catfish genus Ituglanis is described from the Rio Curuá, Rio Xingu basin, Rio Amazonas
drainage, Brazil. Ituglanis apteryx, new species, is promptly distinguished from congeners, except some specimens
of I. parahybae (Eigenmann), by the absence of pelvic fins, girdle, and muscles. The new species differs from I. parahybae
in the pattern of the cephalic laterosensory system; the absence of a posterior cranial fontanel; the presence of an epural;
and the number of branchiostegal rays, ribs, and vertebrae. Ituglanis apteryx is one among the several trichomycterids
lacking pelvic fins. Analysis reveals that pelvic fin loss independently evolved several times during the trichomycterid
radiation.
