Notes. The identifications in Brindle (1970b: 225) are erroneous, all records and figures correspond to Skalistes lugubris ; this allometric variation was seen in Estrada-Álvarez & Nuñez-Bazan (2021). The locality Sierra de Tlalpujahua is in the state of Michoacan, 74 km north of Toluca (not in Mexico state), this locality is amended in Estrada-Álvarez & Nuñez-Bazan (2021).
