Notes. The Morelos, Sinaloa and Sonora specimens represent new state records and provide the northernmost records of this species. Dipropus sus (Candèze) was described from “ Mexique.” Champion (1895) reported the species from the states of Chihuahua, Puebla, Veracruz (as “Cordova’), Guanajuato, Guerrero, Jalapa, and Nayarit (as “Tres Marias Is.”). The holotype is in the Natural History Museum, London, and was examined.

Specimens from Morelos and Veracruz have a more closely and coarsely umbilicate punctation on the pronotum, the punctures being adjacent anterolaterally. Specimens from more northern regions have the pronotal punctation slightly sparser and smaller on the disc.
