Phylogenetic relationships of the suckermouth armoured catfishes (Loricariidae) with emphasis on the Hypostominae and the Ancistrinae

摘要: A phylogenetic analysis of nearly all genera the Hypostominae and Ancistrinae is provided based on osteology, external anatomy, digestive tract anatomy. The results suggest that a paraphyletic assemblage. Delturus Upsilodus form monophyletic group sister to other loricariids. Hemipsilichthys, Isbrueckerichthys, Kronichthys, Pareiorhina with Neoplecostomus Hypoptopomatinae are transferred Neoplecostominae. remainder made by continuing recognition Ancistrinae. returned recognized as tribe, Ancistrini. In addition, four new tribes (Corymbophanini, Hypostomini, Pterygoplichthini, Rhinelepini) described. Hypostomus also paraphyletic, bulk it forming clade Aphanotorulus, Cochliodon, Isorineloricaria. All potential groups within grade into one another; therefore, Isorineloricaria placed in synonymy Hypostomus. Pterygoplichthys Glyptoperichthys polyphyletic, Liposarcus synonyms Pterygoplichthys. Sister Hemiancistrus annectens (including panamensis) which represents an undescribed genus. phylogeny presented compared previous hypotheses. © 2004 Linnean Society London, Zoological Journal Society, 2004, 141, 1−80.
