Justification: Canthon indigaceus has been assessed as Least Concern. This species has a wide distribution across Central America, from Arizona, USA, and Mexico to Costa Rica; it is considered abundant and is mostly found in pastureland, so that it is unlikely to be affected by any major threat processes. However, there are some indications that populations have been declining in the Veracruz part of this species' range.

Geographic Range Range Description: This species has a wide distribution: it has been collected in Arizona and Texas, USA, and in the tropical region of Mexico and extending throughout Central America, from Mexico to Costa Rica. It is a species that inhabits predominantly pastures and open areas. It is one of the most common roller species in Mexico and Central America. It has been recorded in Costa Rica (Guanacaste), Mexico (Guerrero: Acapulco, Atoyac de Alvarez, Pilcaya, Taxco de Alarcon; Hidalgo: Molango de Escamilla, San Felipe Orizatlan, Tepehuacan de Guerero; Jalisco: La Huerta; Morelos: Cuernavaca, Jojutla, Jonacatepec, Xochitepec, Yecapixtla; Quintana Roo: Othon P Blanco; San Luis Potosi: San Luis Potosi; Veracruz: Actopan, Apazapan, Carrillo Puerto, Catemaco, Coatepec, Cotaxtla, Emiliano Zapata, Jalcomulco, Papantla, Puente Nacional; Yucatan: Tizimin) and Nicaragua (Chinandenga, Leon, Managua, Masaya, Rio San Juan, Rivas), with additional localities in Honduras and Guatemala.
