The Brazilian Transcontinental Catfish Expedition OVERVIEW: A field expedition funded by the ACSI (NSF DEB-0315963) was conducted from July 7th to August 1st in Western Brazil, in the states of Mato Grosso, Rondônia, Acre, and Amazonas. The expedition sampled mainly headwater streams of the Paraguay, Tapajós, Madeira, and Purus rivers. A total of 159 field stations were sampled and 217 catfish species, belonging to all South American families except the Andean Astroblepidae, Diplomystidae, and Nematogeneidae, were collected. Of these, 36 species were detected as undescribed and are already assigned to one or more ACSI participant scientists who will describe them (see list below). It is likely that several other undescribed species are among this collection, because many species are so far identify only to genus (see list below). Further on the collecting team, John Lundberg, Flávio Bockmann, Osvaldo Oyakawa, Marcelo R. Britto, and Jonathan Armbruster participated in the initial sorting/identification process. Mark Sabaj, Alberto Akama, Carl Ferraris, Richard Vari, and Luiza Soares-Porto helped identifying digital photographs of several species sent via email. The catfish collection is now being cataloged in MCP Fish Collection and portions of it will be later split and deposited in other relevant collection. A large amount of other “bycatch” fish collected during the expedition is beginning to be worked-up. ACTIVITIES: Two collecting teams, in addition to a truck, traveled separately each day making regular, diurnal collections (cast-net, dip-net, beach-seine, hook&line). The teams camped most nights by large rivers and fished at night with gill-nets, beach-seine, cast-nets, and hook&line (see the Power Point presentation attached). Tissue samples were collected from all catfish morphospecies identified in the field and for many bycatch fish species. These tissue samples are deposited in MCP Tissue Collection. Participants were: Roberto E. Reis (MCP, Expedition Coordinator), José F. Pezzi da Silva (MCP), Edson H. L. Pereira (MCP), Vinicius A. Bertaco (MCP), Pablo C. Lehmann (MCP), Alexandre R. Cardoso (MCP), Francisco Langeani (UNESP), Paulo A. Buckup (MNRJ), Flávio C. T. Lima (MZUSP), and Cláudio Gallina (truck driver). Every day ichthyologists were divided up in two 4-person teams that traveled separately. One ichthyologist traveled in the truck each day and was responsible for the infrastructure (buy food and supplies, find safe camping areas, fix nets, etc). The truck usually stopped before dark to set up camping facilities and spread the gill-nets at dusk. The two teams worked until dusk before gathering together for the night. Teams coordinated by 2-way radios, maps, and GPS. THE ROUTE: Tributaries of the Paraguay, Juruena (Tapajós), Madeira, and Purus Rivers were sampled. The original idea of spending a few days collecting in the upper Juruena River, on the Chapada dos Parecis, was dropped because the pilot trip indicated that the area is severely modified by agriculture. A small portion, better preserved, of the Chapada dos Parecis was indeed sampled. Likewise, the portion of the Acre State west of the Purus River was not collected because of the very bad roads that did not allowed us to pass (Fig. 1).

LIST OF CATFISHES COLLECTED: The list below includes all catfish species identified to date among the specimens collected. All non-catfish taxa are still waiting to be sorted and it is likely that a few additional, not previously noticed, catfishes will be found among them. In most cases, a few characters are listed to diagnose those species to which a specific name was not ascribed. All undescribed species detected to date are marked with “sp. n.” Ichthyologists whose names appear near to the new species, already agreed to describe these taxa, and will start working on them soon. These and other ichthyologists will be studying several other specimens in connection with ongoing revisionary work. A complete list of catfish lots with identification, locality, and number of specimens will be generated from the MCP collection database, as soon as all lots are cataloged, and will be sent to the ACSI website.
