Trichomycterus spelaeus

DoNascimiento, Villarreal and Provenzano 2001







Holotype: MBUCV-V-29602, 54.1mm SL. Paratypes: MBUCV-V-29603, 2 specimens, 34.6 and 29.4mm SL. 


Type locality: Cueva Punto Fijo, 7.5 km N of Cerro Yolanda, Edo, Zulia, Venezuela (10o57’10”N, 72o28’06”W). Possibly present in Cueva Punto Fijo 2 in the same area. These caves are hydrologically connected. Further details in Sociedad Venezolana de Espeleologia (1990).


Water temperature 21oC, current velocity 10l/sec. The stygobitic loricariid Ancistrus galani inhabits a nearby system. Various other stygobitic and stygophilic species are also present. See Rodriguez and Bosque (1990) for further details.


There is little information on the relationships of this species. DoNascimiento, Villarreal and Provenzano (2001) compare its anatomy with various other Trichomycterus species but without conclusive results.
