This dataset contains the digitized treatments in Plazi based on the original journal article Bichuette, Maria Elina, Trajano, Eleonora (2008): Ituglanis mambai, a new subterranean catfish from a karst area of Central Brazil, rio Tocantins basin (Siluriformes: Trichomycteridae). Neotropical Ichthyology 6 (1): 9, DOI: 10.1590/S1679-62252008000100002, URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252008000100002&lng=en&tlng=en
Ituglanis mambai, new species, is described from a cave in the Mambaí karst area, State of Goiás, Central Brazil. The new species distinguishes from epigean and cave congeners by the combination of the following characteristics: posterior supraoccipital fontanel absent; pectoral-fin rays usually i, 7; six pleural ribs; total vertebrae 37-38 behind Weberian apparatus; shorter predorsal length (65.1-70.8% SL); shorter caudal peduncle length (8.4-11.9% SL); shorter dorsal-fin base length (7.7- 11.3% SL); wider interobital width (29.2-36.5% HL); larger mouth width (43.4-64.0% HL); intermediate between epigean and other cave Ituglanis species as regards to both eyes (diameter varying from 0.5 to1.0 mm in adults, 7.8-10.1 % HL) and pigmentation, composed by irregular light brown spots along the body. The latter indicate the troglobitic status for I. mambai. In addition, this species has the maxillae with a discrete medial-posterior projection; fronto-lacrimal one half-length of the maxillae and pointed backwards; posterior process of palatine half its length, with a tenuous medial concavity; 14 dorsal and 12 ventral procurrent rays. In the natural habitat, I. mambai displayed cryptobiotic habits, trying to hide in the graveled bottom or under boulders when disturbed, apparently showing a negative response to light. It was observed a preference to slowmoving waters. Recent flood marks were observed in the stream conduit in March/ April 2007 (end of the rainy season) when less individuals were observed on 300 m of the subterranean stream compared to September 2004 (end of the dry season).
Ituglanis mambai, nova espécie, é descrita de uma caverna localizada na área cárstica de Mambaí, estado de Goiás, Brasil central. A nova espécie difere dos congêneres epígeos e cavernícolas pela combinação das seguintes características: fontanela posterior do supraoccipital ausente; raios da nadadeira peitoral usualmente i, 7; seis costelas; número total de vértebras 37-38; comprimento pré-dorsal menor, 65.1-70.8% do comprimento-padrão; comprimento do pedúnculo caudal menor, 8.4-11.9% do comprimento-padrão; base da nadadeira dorsal menor, 7.7-11.3% do comprimento-padrão; altura maior da cabeça, 46.7-71.6% do comprimento da cabeça; largura da cabeça menor, 89.2-115.7% do comprimento da cabeça; largura interobital maior (29.2- 36.5% do comprimento da cabeça); largura da boca maior (43.4-64.0% do comprimento da cabeça); olhos e pigmentação intermediários entre as espécies epígeas e cavernícolas de Ituglanis - diâmetro dos olhos variando entre 0.5 e 1.0 mm nos adultos, 7.8-10.1 % do comprimento da cabeça e pigmentação composta por manchas irregulares marrom-claras ao longo do corpo. Este último caráter indica o status de troglóbio de I. mambai. Adicionalmente, esta espécie apresenta maxila com uma discreta projeção medial-posterior; fronto-lacrimal 1,5 vezes o tamanho da maxilla e projetado posteriormente; comprimento do processo posterior do palatino metade do seu comprimento total, com uma tênue concavidade medial; 14 raios procurrentes dorsais e 12 ventrais. No ambiente natural, I. mambai mostrou hábitos criptobióticos. Quando perturbados, tentavam entocarse sob os seixos e matacões. Aparentemente mostraram reação negativa à luz. Foi observada uma preferência por remansos. Marcas de enchentes recentes foram observadas no conduto do riacho subterrâneo em março/ abril 2007 (fim da estação chuvosa) quando um número menor de indivíduos foi observado, comparando-se a setembro de 2004 (final da estação chuvosa).
