Description
This dataset contains the digitized treatments in Plazi based on the original journal article Bichuette, Maria Elina, Pinna, Mario César Cardoso de, Trajano, Eleonora (2008): A new species of Glaphyropoma: the first subterranean copionodontine catfish and the first occurrence of opercular odontodes in the subfamily (Siluriformes: Trichomycteridae). Neotropical Ichthyology 6 (3): 301-306, DOI: 10.1590/S1679-62252008000300002, URL: scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252008000300002&lng=en&tlng=en A new species of the rare copionodontine genus Glaphyropoma is described from subterranean waters in the Diamantina Plateau, Bahia State, central northeastern Brazil.
This is the first troglomorphic species in the subfamily Copionodontinae. It is distinguished from all other copionodontines by the presence of opercular odontodes, and further distinguished from its only congener, G. rodriguesi, by the reduction of dark integumentary pigmentation. The new species shares the single synapomorphy previously proposed for Glaphyropoma, the marked narrowing of the first hypobranchial and indirect character evidence also supports its inclusion in the genus.

The presence of opercular odontodes in the new species, in combination with a reviewed hypothesis of sister group relationship between Copionodontinae and Trichogeninae, indicate that the absence of opercular odontodes in previously-known copionodontines is secondary, rather than primitive. Uma nova espécie do raro gênero de Copionodontinae Glaphyropoma é descrita de águas subterrâneas da Chapada Diamantina, estado da Bahia, região central do Nordeste Brasileiro.
Esta é a primeira espécie troglomórfica na subfamília Copionodontinae. Distingue-se de todos os outros Copionodontinae pela presença de odontódeos operculares, e de seu único congênere, G. rodriguesi, também pela redução de pigmentação tegumentar. A nova espécie apresenta a única sinapomorfia previamente proposta para Glaphyropoma, um estreitamento acentuado do primeiro hipobranquial e evidência indireta de outros caracteres também suportam sua inclusão no gênero.
A presença de odontódeos operculares na nova espécie, em combinação com uma hipótese revisada de grupo-irmão entre Copionodontinae e Trichogeninae, indica que a ausência de odontódeos operculares nos Copionodontinae previamente conhecidos é secundária e não primitiva.
