Distribution of cave-dwelling nicoletiid genera in northern Mexico and the southern United States. Shaded areas are municipalities and counties in Mexico and the United States, respectively, with documented occurrences for each genus. Dark gray shaded areas are karst exposures in the United States. Inset is the distribution of Spinanycta alabamensis sp. nov. in northern Alabama with Alabama Cave Survey cave codes labeled. Bobcat Cave (AMD1283) is the type locality.
