"Glaphyropoma" is a genus of catfishes (order Siluriformes) of the family Trichomycteridae. It includes two species, "G. rodriguesi" and "G. spinosum".cite journal|journal=Neotropical Ichthyology|volume=6|issue=3|pages=301-306|year=2008|title=A new species of "Glaphyropoma": the first subterranean copionodontine catfish and the first occurrence of opercular odontodes in the subfamily (Siluriformes: Trichomycteridae)|first=Maria Elina|last=Bichuette|coauthors=de Pinna, Mario César Cardoso; Trajano, Eleonora]

The single synapomorphy proposed for "Glaphyropoma" is the marked narrowing of the first hypobranchial, giving the hypobranchial a slender shape.

"G. rodriguesi" grows to about 5.1 centimetres (2.0 in) SL and originates from the Mucujê River, a tributary of Paraguaçu River in Brazil.FishBase species|genus=Glaphyropoma|species=rodriguesi|year=2007|month=July]

"G. spinosum" is known to grow as large as 5.8 cm (2.3 in) SL. It is known from subterranean waters in the Diamantina Plateau of the Bahia State in central northeastern Brazil. This is the first-known troglomorphic species in the subfamily Copionodontinae. These fish live in quartzitic caves formed by erosion by rain. The water depth in the creek where the catfish live varies mostly between 10 and 50 cm (4 and 20 in), with moderate current and some spotty accummulation of plant debris where fish are found foraging.
