Abstract

The skeletal anatomy of Hypostomus plecostomus (Linnaeus) is described. Details of the osteology of H. plecostomus are compared to homologous features in other Loricariidae and outgroup siluroids as the foundation for a phylogenetic analysis of the six loricariid subfamilies (Ancistrinae, Hypoptopomatinae, Hypostominae, Lithogeninae, Loricariinae, Neoplecostominae). Hypostomus plecostomus is shown to possess a mosaic of both primitive and derived features, although no uniquely derived characters were found which diagnose either Hypostomus or the subfamily Hypostominae. The Loricariidae is diagnosed as monophyletic on the basis of 16 synapomorphies. Numerical cladistic analysis using PAUP (Phylogenetic Analysis Using Parsimony) revealed the following pattern of relationship: ((Hypoptopomatinae)((Loricariinae)(Ancistrinae+Hypostominae))) Representatives of the Neoplecostominae and Lithogeninae were not included in the numerical analysis; their phylogenetic relationshipswere inferred a posteriori. Four characters diagnose the clade composed of the Loricariinae, Hypostominae, and Ancistrinae. Eight characters diagnose the genera assigned to the Hypostominae + Ancistrinae as monophyletic. Evidence for monophyly of the Ancistrinae is presented and the consequent paraphyly of the Hypostominae is discussed. The results of this analysis are compared withprevious loricariid classifications.
