Glaphyropoma spinosum

Bichuette, de Pinna and Trajano 2008







Holotype: MZUSP 99742 58.2mm SL. Paratypes: MZUSP 99743 4 specimens 34.9mm – 45.6mm SL.


Type locality: Chapada Diamantina, Municipio de Andarai, Provoado de Igatu, Gruna dos Torras, rio Paraguacu drainage, Bahia, Brazil. 12o52’40.4”S, 41o18’43.3”W. This species coexists with the troglobitic Copionodon undescrined species.


The cave is developed in quartzite.


This species is clearly a member of the trichomycterid subfamily Copionodontinae. There are only two species in the genus, this one and Glaphyropoma rodriguesi de Pinna 1992 (Eschmeyer et al. 2021). Trajano (2021) says that the genus Glaphyropoma is monotypic but this is not correct.

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.”
