Hypsolebias shibattai n. sp. is described from a temporary pool located in the rio São Francisco basin, state of Bahia, Brazil. Hypsolebias shibattai belongs to the H. magnificus species-group. This new species differs from all other species of Hypsolebias by having a unique color pattern in the males: a golden-yellow coloration on the head, opercular region and body up to the beginning of the dorsal fin (vs. absence of golden-yellow color on anterior portion of body).
