With 40 figures Phylogenetic relationships of the suckermouth armoured catfishes (Loricariidae) with emphasis on the Hypostominae and the Ancistrinae Downloaded from https://academic.oup.com/zoolinnean/article-abstract/141/1/1/2624207 by guest on 08 September 2019 JONATHAN W. ARMBRUSTER* Department of Biological Sciences, 331 Funchess, Auburn University, AL 36849, USA Received December 2000; accepted for publication October 2003 A phylogenetic analysis of nearly all genera of the Hypostominae and the Ancistrinae is provided based on osteol- ogy, external anatomy, and digestive tract anatomy. The results suggest that the Hypostominae is a paraphyletic assemblage. Delturus and Upsilodus form a monophyletic group sister to all other loricariids. Hemipsilichthys, Isbrueckerichthys, Kronichthys, and Pareiorhina form a monophyletic group with Neoplecostomus and the Hypop- topomatinae and are transferred to the Neoplecostominae. The remainder of the Hypostominae is made paraphyl- etic by the continuing recognition of the Ancistrinae. Ancistrinae is returned to the Hypostominae and recognized as a tribe, Ancistrini. In addition, four new tribes (Corymbophanini, Hypostomini, Pterygoplichthini, and Rhinele- pini) are described. Hypostomus is also paraphyletic, the bulk of it forming a monophyletic clade with Aphanotoru- lus, Cochliodon, and Isorineloricaria. All of the potential monophyletic groups within Hypostomus grade into one another; therefore, Aphanotorulus, Cochliodon, and Isorineloricaria are placed in the synonymy of Hypostomus. Pterygoplichthys and Glyptoperichthys are also polyphyletic, and Liposarcus and Glyptoperichthys are recognized as synonyms of Pterygoplichthys.
