Attestations from sources in English: 

Tlacahuepan = a ritual title for a young man who was immolated at the end of the festivals celebrated in the month of Toxcatl; a divine name, a brother god and companion of Huitzilopochtli; possibly also a cadet of Tezcatlipoca; finally, this title was taken as a personal name (which may be the case, for e.g., in the Matrícula de Huexotzinco, folio 650 recto).

Our English translation (above) comes from the French of A. Wimmer (2004), who drew from Sahagún and Clavijero: "1. titre rituel, jeune homme que l'on immolait à la fin des fêtes célébrées au mois de Toxcatl. / titre rituel, jeune homme que l'on immolait à la fin des fêtes célébrées au mois de Toxcatl. / nom divin, un dieu frère et compagnon de Huitzilopochtli. / n.pers.... J.de Durand-Forest le présente comme cadet de Tezcatlipoca.
