“…Teleocichla preta, similar to many other species of endemic Rio Xingu fishes, highlights the complex evolutionary processes that may be at play in this singular Amazonian tributary. A large diversity of forms and ecologically specialized fishes inhabit the Xingu basin (Kullander, 1988;Lowe-McConnel, 1991;Jegu, 1992;Zuanon, 1999;Py-Daniel & Zuanon, 2005), but many of them correspond to putative new species that remain virtually unknown to science. Because this region is severely threatened by increased anthropogenic developments, it is imperative to stimulate the study and formal description of these forms, in order to understand their origin and ensure the preservation of one of the most unique concentrations of freshwater fish diversity in the Neotropics.…”

Teleocichla preta nov. sp. inhabits the rapids along the Rio Xingu and lower portion of the Rio Iriri. It is the largest species in the genus, reaching 121·3 mm standard length (LS ) while others do not reach more than 87·8 mm LS . Teleocichla preta is distinguished from all other species of Teleocichla by the unique blackish (in live specimens) or dark brown (preserved specimens) overall colouration of the body, which masks the faint vertical bars or zig-zag pattern of blotches on the flanks. Teleocichla preta also has a deeper body and a deep laterally compressed caudal peduncle, unlike any other congener, as well as a stout lower pharyngeal tooth plate bearing molariform teeth on its median area.

“…These activities have become economically profitable within some communities of these regions and, in many cases, constitute the entire source of income for several families. According to Rapp Py-Daniel & Zuanon (2005) and Camargo et al (2011) this practice has become most frequent in Altamira since end of the1980's, when gold prospectors that lost their jobs began to collect loricariids fish. The capture of attractive species for the ornamental fish trade was possible with the adaptation of old techniques employed in gold prospect at great depths (up to 15 meters), such as the use of air compressors, diving masks and lanterns.…”

“…According to Zuanon (1999) and Rapp Py-Daniel & Zuanon (2005), Spectracanthicus zuanoni is a moderate reophilic species that is found in rock-bottom areas subjected to backwater and strong currents. Specimens were found individually or in groups of three, under shelter boulders (adults) and spaces beneath rocks (juveniles), up to 2m deep.…”

A taxonomic review of Spectracanthicus Nijssen & Isbrücker, including Oligancistrus Rapp Py-Daniel, following a phylogenetic study, is presented. Additionally to S. punctatissimus (Steindachner) and S. murinus Nijssen & Isbrücker, three new species are recognized based on the examination of 159 specimens: S. immaculatus n. sp. from rio Tapajós basin, differs from its congeners by its color pattern consisting of a dark gray body, with no dots or spots, and by having very slender teeth; Spectracanthicus tocantinensis n. sp., from the rio Tocantins drainage is distinguished by the color pattern consisting of dark brown or black body with small, yellowish dots (except in S. punctatissimus), presence of thick teeth, infraorbital 4 forming most of the posterior edge of the orbit and the large basipterigium fenestrae; and Spectracanthicus zuanoni n. sp., from the rio Xingu basin is diagnosed by its color pattern consisting of large, white spots and by the larger orbital diameter. Other characters based on osteological features are also usefull to distinguish the species. A key to the species of the genus and a brief discussion of their threats and conservation are also provided.A revisão taxonômica de Spectracanthicus Nijssen & Isbrücker, incluindo Oligancistrus Rapp Py-Daniel, baseada em estudos filogenéticos recentes, é apresentada. Adicionalmente a S. punctatissimus (Steindachner) e S. murinus Nijssen & Isbrücker, três espécies novas são reconhecidas baseadas no exame de 159 espécimes: S. immaculatus, sp. n. proveniente da bacia do rio Tapajós, difere de suas congêneres pelo padrão de colorido do corpo cinza escuro sem pontos ou manchas e por possuir dentes bastante delgados; Spectracanthicus tocantinensis sp. n., da bacia do rio Tocantins pode ser distinguida pelo padrão de colorido do corpo marron escuro ou preto com pontos amarelados (exceto de S. punctatissimus), presença de dentes espessos, infraorbital 4 formando quase toda a margem posterior da órbita e pela presença de uma grande fenestra no basipterígio; e Spectracanthicus zuanoni sp. n., da bacia do rio Xingu é diagnosticada pelo padrão de colorido cinza escuro com grandes pontos brancos e por possuir maior diâmetro infraorbital. Outros caracteres osteológicos também podem ser utilizados para distinguir as espécies. Uma chave para as espécies do gênero e uma breve discussão sobre suas ameaças e conservação são também fornecidas.

“…O estado do Pará é grande fornecedor de peixes ornamentais da família Loricariidae (acaris) (RAPP PY-DANIEL e ZUANON, 2005;PRANG, 2007). No rio Xingu ocorrem pelo menos 55 espécies de Loricariidae, sendo 31 delas bem valorizadas no mercado da aquariofilia (CAMARGO e GHILARDI, 2009).…”

This paper describes the marketing ways and the margins of trade of five species of ornamental fish species, which are caught on the Xingu River, State of Pará, Brazil. Data collection was carried out intentionally and sequentially of 51 actors of the supply chain, including fishermen, wholesalers and national and international retailers. The results indicate that ornamental fish can undergo up to six marketing agents before arriving to the finish consumer. The sunshine pleco (Scobinancistrus aureatus) is the species of the greatest value in the market, being sold to the final consumer at the price of up to R$ 543.00, an increase of 1,361% in the North American market and 1,527% in the European market. The marketing margins are high: 92.68% in the European market and 89.24% in the North American market. Looking at the distributions of benefits, it is concluded that the international market appropriates the greater part of the value generated by the activity.Key words: fishery economy; trade; aquarium fish; Amazonia. RESUMOEste trabalho descreve os canais e as margens de comercialização de cinco espécies de peixes ornamentais capturadas no rio Xingu, estado do Pará, Brasil. A coleta de dados foi realizada de forma intencional e sequencial junto a 51 agentes da cadeia de comercialização, incluindo pescadores, atacadistas e varejistas nacionais e internacionais. Os resultados indicam que as espécies ornamentais podem passar por até seis agentes de comercialização antes do consumidor final. O acari picota ouro (Scobinancistrus aureatus) é a espécie mais valorizada no mercado, chegando a ser vendida ao consumidor final pelo preço unitário de R$ 543,00, um aumento de 1.361% no mercado norte americano e 1.527% no mercado europeu em relação ao preço da exportação brasileira. As margens de comercialização são elevadas: 92,68% no mercado europeu e 89,24% no mercado norte americano. Observando as distribuições de benefícios, conclui-se que o mercado internacional se apropria da maior parcela do valor gerado pela atividade.
