Abstract 
We describe a new species of frog Sarcohyla floresi sp. nov. from the Sierra Madre del Sur of Guerrero and the southern part of Estado de México, based on specimens previously referred to as S. pentheter and newly obtained specimens. The new species has stream-dwelling tadpoles with labial tooth row formula 2(2)/3 and adults with a distinctive dark dorsolateral band bordered by a white line. S. floresi can be included in the S. bistincta group.

Etymology. This species is named after Oscar Flores Villela, a researcher and teacher at the Museo de Zoologia, Facultad de Ciencias, Universidad Nacional Autonoma de México, to recognize his life-long commitment to the science and conservation of amphibians and reptiles in México.

Natural history. The holotype was found inside a fissure of a large boulder on a mountain crest far from a body of water. The type locality consists of dry deciduous forest characteristic of the Pacific slopes of the Sierra Madre del Sur of Guerrero (Rzedowski, 1978). All tadpoles were found during the day in pools formed in streams.
