Additional data: Venomous! Another subspecies, S. r. sinaloensis has been proposed but the description is woefully incomplete and the locality data are likely suspect (CAMPBELL & LAMAR 1989: 376). Sistrurus ravus lutescens (HARRIS & SIMMONS 1978) is not listed in WELCH 1994 and not recognized as subspecies by GOLAY et al. (1993).
