Aegomorphus albosignus was described from males and females from Mexico (Jalisco).According to Chemsak & Noguera (1995) “this species is readily recognizable by the pale pubescent face and the white oblique and longitudinal fasciae of the elytra” However, as in many other species of Aegomorphus , Acanthoderes , and Scythropopsis the elytral pubescent pattern, as well as the color of the pubescence of the frons are extremely variable. This is clearly shown in the type series (see photographs at Bezark, 2019) where the longitudinal white pubescent band on the elytra varies from being well defined, slightly distinct or even absent or nearly so ( Fig. 92-98 ). Thus, it can be difficult to recognize the species, which is only possible by examining other details provided in the original description.
