This genus was for a while considered invalid and assigned to Diplodactylus but has now been revalidated: see Reptile Database entry for details. In addition, over recent years the number of species recognised within the genus has jumped from one to 14.
Kinghorn characterised the genus as follows: digits cylindrical, covered above with imbricate scales and on the sides and under surfaces with small spine-like tubercles. The claw is retractile beneath a nail-like scale, and surrounded below and at the sides by a rosette of small spine like tubercles. Body covered with imbricate scales; tail with squarish imbricate scales.
