Comment

Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 315 (following Dubois, 1987 "1986", Alytes, 5: 61), placed this in the Hoplobatrachus occipitalis group. Loveridge, 1957, Bull. Mus. Comp. Zool., 117: 344, reported the species as occurring in Morocco and Eritrea, but did not cite vouchers; these occurrences require confirmation.
