Ituglanis ramiroi

Bichuette and Trajano 2004







Holotype: MZUSP 79865 27.1mm SL.

Paratypes: MZUSP 79866 30.2mm - 30.9mm SL, MZUSP 79867 25.4mm - 31.3mm SL, MZUSP 79868 29.3mm SL.


Known only from the type locality: São Bernardo Cave, Terra Ronca State Park, São Domingos, Goiás, Brazil (13o49'S 46o21'W).


A small pool above main river level fed only by percolation water.


A multigene analysis of many Trichomycterus and Ituglanis species by Katz et al. (2018) suggested that I. ramiroi is sister to I. goya and both are sister to a group of three species I. amazonicus, I. eichomiarum and I. parkoi. See also Ochoa et al. (2017).

Conservation Status

TLO [NE] [VU D2:3.1:2011]

Ituglanis ramiroi is known from a single cave, São Bernardo Lapa, part of the São Bernardo-Palmeiras System, Paranã River basin, Alto Tocantins, municipality of São Domingos, Goiás. It occurs in puddles formed by infiltration water in the rock and Extent of occurrence was estimated at 3.5km2. The cave is located in the State Park of Terra Ronca, but the source of the river that crosses the cave is outside protected area and livestock occupation, which may represent a threat by the silting of the river. Therefore, Ituglanis ramiroi was categorized as Vulnerable (VU) by criterion D2. Recovery of riparian forests and degraded areas around the cave is necessary. [Google Translate].
