Abstract: Reexamination of the syntypes of the enigmatic Trichomycterus venulosus, described from Páramo de Cruz Verde, Eastern Cordillera of Colombia, allowed us to assess its actual taxonomic status. This nominal species is demonstrated to constitute a junior synonym of Eremophilus mutisii, and then not represents a case of extinction of a fish endemic to Colombia, as currently accepted.

“…Eremophilus is a monotypic trichomycterin genus endemic to the Colombian central highlands (Maldonado‐Ocampo et al., 2005), originally diagnosed primarily by the absence of pelvic fins (externally) and the corresponding lack of the pelvic support skeleton basypterigia (internally) (Arratia, 1990; DoNascimiento et al., 2014). Such a pelvic‐less condition, however, has subsequently been documented in at least 12 other trichomycterins, including species of Ituglanis , Silvinichthys and Trichomycterus (Arratia, 1998; Barbosa & Costa, 2003; Datovo, 2014; Fernández & de Pinna, 2005; Fernández & Vari, 2000; Ferrer & Malabarba, 2011), and there is substantial consensus that this condition has independently evolved multiple times during the diversification of the subfamily (Datovo, 2014).…”

Such condition has a homoplastic distribution within Another derived character shown by Trichomycterus rosablanca consists of the lachrimal/antorbital bone not enclosing the infraorbital canal (Figure 3).…”

“…Among trichomycterines, the canals are also fused and continuous to each other in Hatcheria and Bullockia (Arratia and Huaquin, ), but are separate from each other in Rhizosomichthys . In Eremophilus and Scleronema the nasal canal is variably present (Arratia and Huaquin, ; DoNascimiento et al, ). In Silvinichthys , the frontal canal is absent, and the nasal canal is present in S. mendozensis, S. leoncitensis , and S. gualcamayo , but is absent in S. bortayro and S. huaichi (Arratia, ; Fernández and de Pinna, ; Fernandez et al, ).…”

“…“Posse”). Additionally, we included data from three species of Trichomycterus : T. brachykechenos (Ferrer and Malabarba, ); T. cachiraensis (Ardila‐Rodríguez, ); and T. steindachneri (DoNascimiento et al, ). These three species were recently proposed to be closely related to the genus Ituglanis (DoNascimiento et al, ), based on a supposed morphocline in relation to the reduction of the cranial fontanel, and they are included here as an outgroup for comparison.…”
