Original Description: 

  MATAMOROS, W. A. & J. F. SCHAEFER (2010): A new species of Profundulus (Cyprinodontiformes: Profundulidae) from the Honduran central highlands. Journal of Fish Biology 2010 (76): pp 1498-1507


  Following the authors, this species is named "after D. and H. Portillo, who guided Wilfredo Alfredo Matamoros Ortega to the type locality and provided valuable natural history information for the area." The name of the species can be translated with "The Tlaloc of the Portillo's".

  The genus Tlaloc was erected by José Álvarez del Villar and Jorge Carranza Fraser in 1951 for 14 specimens of Cyprindont fish from Chiapas, collected by the US American zoologist Clarence James Goodnight. The name refers to the Aztek divinity Tláloc, who was in the Aztek mythology the deity for rain, fertility and water. Why they had chosen the Aztec god Tláloc instead of Chaac, the Mayan god for rain, thunder and lightning, who was worshipped by the Mayan people in Chiapas, where the types were collected, is unkown.
