Vasconcelos, Raquel, Köhler, Gunther, Geniez, Philippe & Crochet, Pierre-André, 2020, A new endemic species of Hemidactylus (Squamata: Gekkonidae) from São Nicolau Island, Cabo Verde, Zootaxa 4878 (3), pp. 501-522 : 520

Hemidactylus boavistensis chevalieri comb. nov. Angel, 1935

Name-bearing types. Thirteen syntypes of which 12 are still present in the MNHN collections: MNHN-RA- 1935.178, 179, 179A, 179B, 180, 180A, 181, 181A, 182, 183, 184 & 184 A. Based on the information in the MNHN catalogue, the two beforelast come from ‘ Santa Maria’ and the rest from an unkown locality on ‘ Sal’ .

Type locality. Santa Maria , Sal Island & unkown locality, Sal Island, Cabo Verde Archipelago .

Diagnosis. Very similar to H. b. boavistensis but usually with six lamellas under the first finger according to Angel (1935). Angel (1935) also claims that head and nape colouration is generally also different as regards to the transverse bands, which are usually lacking or less clear than in the nominotypical subspecies (see Fig. 7 ), but we found this to be highly variable and of little use for identification. Even though dorsal colouration is highly variable, Sal individuals are usually darker than Boavista ones.

Distribution. Sal Island, Cabo Verde Archipelago.

Conservation status. Not Evaluated. Identical threats as referred above.
