Etymology. The specific name is to be treated as a Latin adjective and refers to the rattlesnake genus Crotalus Linnaeus, whose rattle at the end of tail is raised, becoming similar to the embolus of the male palp of this species (Figs 43‒44).

Diagnosis. Males of S. crotalica (Figs 33, 43) are similar to those of S. cepa (Figs 32, 42) by the elongate, thin embolus, but can be recognized by the embolus forming a clockwise spiral perpendicular to the axis of the left male palp.
