Abstract
We review the complex history of those species included in the Hypostomus emarginatus species complex and recognize them in Isorineloricaria and Aphanotorulus. Isorineloricaria consists of four valid species: I. acuarius n. sp., I. spinosissima, I. tenuicauda, and I. villarsi. Aphanotorulus consists of six valid species: A. ammophilus, A, emarginatus, A. gomesi, A. horridus, A. phrixosoma, and A. unicolor. Plecostomus annae and Hypostoma squalinum are placed in the synonymy of A. emarginatus; Plecostomus biseriatus, P. scopularius, and P. virescens are placed in the synonymy of A. horridus; Plecostomus winzi is placed in the synonymy of I. tenuicauda, and one new species, I. acuarius is described from the Apure River basin of Venezuela. Aphanotoroulus can be distinguished from Isorineloricaria by having caudal peduncles that do not become greatly lengthed with size and that are oval in cross section (vs. caudal peduncle proportions that get proportionately longer with size and that become round in cross-section), and by having small dark spots (less than half plate diameter) on a light tan background (vs. spots almost as large as lateral plates on a nearly white background.

Key words: Amazonas, Andean, Brazilian Shield, Guiana Shield, Hypostomus, Squaliforma, taxonomy


In diesem paper wird Squaliforma mit Aphanotorulus synonimisiert, wobei einige bisher als Squaliforma bekannte Arten auch zu Isorineloricaria überstellt werden. Nebenbei wird mit Isorineloricaria acuarius auch eine neue Art beschrieben.

Wer möchte darüber diskutieren?

Hi

Ich liebe L-Nummern. Die haben Bestand und werden nicht alle
paar Jahre neu ausgewürfelt.
