Onthophagus fuscus canescens Zunino & Halffter 1988: 83 View in CoL –85; Navarrete-Heredia & Galindo 1997: 3; Anduaga 2000: 130; Krajcik 2006: 106; Pulido-Herrera & Zunino 2007: 103; Moctezuma et al. 2016: 33, 35–36.

Type material examined (1 male, 2 females). Paratypes. 1 male, 1 female: “ México, Parque Nacional J. M. Morelos, Morelia , Michoacán, 25/VII/64, P. Reyes C. col., en hongos” ( GHC) ; 1 female: “ México, Valle de Bravo , Edo. de México, 25/VI/67, col. G. y V. Halffter, cebo excremento humano” ( VMC) .

Non-type material examined. 1 female: “ México, Michoacán, Tejamaniles , 17/VIII/90. A. Morales, col.” ( CEMT) .

Remarks. Length: 9.1 ± 0.1 mm. The following set of characters help us to support the new status of O. canescens ( Table 1): pronotal pubescence medially absent (densely covering the entire surface in O fuscus ); short elytral pubescence (long elytral pubescence in O. fuscus ); major male frontal carina completely impressed (not impressed laterally in O. fuscus ); major male pronotal prominence obtusely trapezoidal (obtusely triangular in O. fuscus ); female frontal carina complete, rounded (not impressed laterally, trapezoidal in O. fuscus ); apical-superior area of the parameres trapezoidal (obtuse in O. fuscus ); apex of the inferior right lobe concave (claw shaped in O. fuscus ). Onthophagus canescens occurs between 1700–2100 m in La Sierra de Mil Cumbres, central-western Trans-Mexican Volcanic Belt ( Fig. 17 View FIGURE 17 ).
