| Sumario: | An update commented list of the snake genus Apostolepis from South America, with keys for identification of the species. They are fossorial snakes that present different coloration according their distribution: (a) 7 to 3 dark stripes coloration, without light nuchal collar (if present, vestigial), with snout not projected beyond jaws - in Amazonian and enclaves within Caatinga domain; (b) 5 dark striped dorsal pattern, snout projected, usually without white nuchal collars — from region of contact between Cerrado and Chaco domains; (c) dorsal pattern coloration uniformly red, with nucho-cervical collars, snout usually projected — in Cerrado with dispersion to Chaco and Caatinga; (d) 2 or none dark stripes dorsally, venter immaculate or with black blotches, snout projecting: (e) an aberrant pattern with oblique black dorsal stripes, without collars, head black and snout projecting — one species in an enclave within Caatinga, with 17 rows of scales instead of 15. |
