This species is clearly a member of the trichomycterid subfamily Copionodontinae.

Conservation Status

[NE] [VU B1ab(iii):3.1:2011]

Glaphyropoma spinosum is endemic in Brazil, found in seven caves in the region of Chapada Diamantina, BA. These caves do not form a single system, so they represent seven subpopulations, in an area of occupation of 25km2. Although most of these caves are located inside Chapada Diamantina National Park, there is still illegal artisanal mining activity, which affects the quality of the habitat, by removing the substrate in its microhabitat and altering the water flow. Thus, Glaphyropoma spinosum was categorized as Vulnerable (VU) by criterion B1ab (iii). Although it is almost totally inside a Conservation Unit, it is necessary to restrain the illegal mining activity practiced there.”
