CommentSynonymy after Filipe Sousa (pers. comm.). See also comment on T. rudis.

Diagnosis: Giant gecko with SVL above 100mm [maximum SVL 155 mm (Bocage, 1896), 103.6 mm on average; (Schleich, 1987)]; eye/ear opening ratio 1.5– 2.0 (Schleich, 1987); ear–eye/eye–snout distance ratio slightly ?1 (Schleich, 1984, 1987). Eight to 12 supralabials and seven to nine infralabials (Schleich, 1984); eight to 12 enlarged lamellae under the 4th finger; 160–195 midbody scales (Joger, 1984b); flatter apical dorsal tubercles (Fig. 5D1) with 16 transverse rows (Schleich, 1984); several enlarged tubercles between the eye and the ear opening. Grey dorsal or olive greyish pattern with a broad, light well-defined middorsal line with generally five large saddle-like marks (Figs 6D1, 7D1); cream ventral parts, yellow on the lower parts; big dark spots on the labials, creating an alternating light and dark pattern; eye iris dark grey with a typical vertical light area around the pupil, joining the upper and lower parts of the eye which are also light.
It differs from other Tarentola from the same clade D, T. ‘rudis’ from Santiago, Fogo, Brava, Rombos, and Maio, besides from its size, by the absence of a keel on dorsal tubercles. Unlike all other Cape Verdean Tarentola, strong vocalisations play a clear role in social behaviour (Schleich, 1982b, 1987). This species avoids vertical surfaces presumably due to its weight, and presents a robust body with typical extreme fat storage (Schleich, 1987).

Diagnosis (brancoensis): Giant gecko with SVL above 100mm [maximum SVL 113 mm, 98.0 mm on average (Schleich, 1987)]. It differs from T. g. gigas by its smaller body mass, by the ratio between the width and length of the fourth toe being generally higher than 1:5, by pre- senting a lower scale count around midbody (160–195 versus 180–213) and a shorter snout (Schleich, 1984; Joger, 1984b).

Diagnosis (gigas): Giant gecko, SVL larger than 100 mm [maximum SVL 155 mm (Bocage, 1896), 109.5 mm on average (Schleich, 1987]. It differs from T. g. bran- coensis by the ratio between the width and length of the fourth toe being generally lower than 1:5, by presenting a higher scale count around midbody (180–213 versus 160–195) and a longer snout (Schle- ich, 1984; Joger, 1984b).
