Abstract
Hypostomus latirostris was originally described by Regan (1904) from "River Jungada [= rio Jangada], Matto Grosso and Goyaz"; however, the species is rarely mentioned in taxonomic works on Hypostomus from Paraguay. Herein, the two syntypes of Plecostomus latirostris were examined showing critical differences between them. After the analysis of a large sample of recently collected specimens from the upper rio Paraguay basin we concluded that the two syntypes from the rio Jangada indeed belong to different species. Hypostomus latirostris is redescribed and a lectotype is designated herein. The other syntype (now a paralectotype of H. latirostris) is designated as paratype of Hypostomus renestoi, new species. Hypostomus renestoi can be differentiated from H. latirostris by having robust teeth (vs. slender); by having 28-77 teeth on the premaxilla (vs. 79-111) and 25-64 on the dentary (vs. 79-109); by having small and more conspicuous dark spots (vs. larger and less conspicuous dark spots); by having dorsal and mid-dorsal series of plates with moderate hypertrophied odontodes (vs. lacking hypertrophied odontodes on lateral series of plates); and usually by attaining a smaller size.

    A checklist of Recent and fossil catfishes (Order Siluriformes) is presented, summarizing taxonomic literature published through 2005. From 4624 nominal species group names and 810 genus group names, 3093 species are recognized as valid, and are distributed among 478 genera and 36 families. Distributional summaries are provided for each species, and nomenclatural synonymies, including relevant information on all name-bearing types, are included for all taxa. One new name is proposed herein: Clariallabes teugelsi, as a replacement for Clarias (Allabenchelys) dumerili longibarbis David & Poll, 1937, which is preoccupied by Clarias longibarbis Worthington, 1933, but has been treated as a valid species of Clariallabes by Teugels. Acrochordonichthys melanogaster Bleeker, 1854, is designated as type species of Acrochordonichthys Bleeker, 1857, inasmuch as no earlier valid designation has been found. A new genus Pseudobagarius, is proposed for the "pseudobagarius group" of species formerly placed in Akysis. The status of 228 species group names remains unresolved and 31 names based on otoliths ascribed to catfishes are listed but not placed into the checklist. The current emphasis given to catfish taxonomy at present is likely to result in a dramatic increase in the total number of valid taxa as well as major changes in the membership of some of the higher level taxa recognized here.

    The Hypostomus cochliodon group consists of eight species that were formerly recognized as Cochliodon Kner: H. cochliodon Kner, H. hondae (Regan), H. levis (Pearson), H. oculeus (Fowler), H. plecostomoides (Eigenmann), H. pospisili (Schultz; a synonym of H. hondae), H. pyrineusi (Miranda-Ribeiro), and H. taphorni (Lilyestrom) and four additional species described herein: H. ericius, H. hemicochliodon, H. pagei, and H. sculpodon. The species occur in four phenetic groups: the intermediate group of H. hemicochliodon and H. sculpodon that appear to be transitional species between other Hypostomus and the H. cochliodon group in terms of diet and tooth shape, a monotypic group containing H. cochliodon, a group characterized by an odontodeless opercle that contains H. ericius, H. levis, H. oculeus, H. pyrineusi, and H. taphorni, and an undifferentiated northern group that contains H. hondae, H. pagei, and H. plecostomoides.

    Tropical South America possesses the largest ichthyofauna of any continental region. To test whether palaeohydrological changes may have been the causes of such diversification, the 'hydrogeological' hypothesis, the phylogenetic relationships of 51 representatives of the catfish genus Hypostomus (Siluriformes: Loricariidae) were inferred using mitochondrial D-loop haplotype sequences. Specimens were collected in all main tropical South American rivers systems east to the Andes. The major interrelationships found with the D-loop data were confirmed with a subset of 21 species using complete internal transcribed spacer (ITS) region sequences. The phylogenetic analysis indicate that the genus Hypostomus can be divided into four monophyletic clades. The historical biogeographical analysis of each of these clades allows the identification of seven major cladogenetic events. Using calibrated D-loop and ITS molecular clocks, date estimations were attributed to each of these cladogenetic events allowing a linkage between four of them with documented hydrogeological changes. Comparisons with published distribution patterns of unrelated fish groups indicate that several of the reconstructed and dated hydrogeological-cladogenetic events may have acted at a large scale on the diversification of Neotropical freshwater fish fauna during late Tertiary.
