SynonymPhyllodactylus andysabini ARTEAGA, BUSTAMANTE, VIEIRA, TAPIA & GUAYASAMIN 2019 
DistributionEcuador: Galapagos Islands (Isabela Island)

Type locality: western slopes of Wolf Volcano (-0.00225, -91.39602; 576 m), Isabela Island, Galápagos, Ecuador

TypesHolotype. MVECCD 1924, an adult of undetermined sex collected by Alizon Llerena on July 20, 2006. 
DiagnosisDiagnosis: males 7.8 cm, females 8 cm. This species is placed in the genus Phyllodactylus based on phylogenetic evidence (Fig. 1). The species is compared to other geckos traditionally assigned to P. galapagensis. From P. galapagensis, it differs in lacking pointed tubercles on the top of the head. From P. maresi and P. duncanensis, it differs in having blunt and symmetrical fingertips, as opposed to asymmetrical pinecone-shaped fingertips (Fig. 6). From P. simpsoni, it differs in having supranasals not in contact in 9 out of 9 individuals examined (versus in contact in 8 out of 14 individuals of P. simpsoni; Fig. 7) and having the throat densely stippled with dark brown pigment (versus immaculate throat in 9 out of 14 individuals of P. simpsoni; Fig. 8). Genetic divergence in a 181 bp long fragment of the mitochondrial 12S gene between the sister species P. andysabini and P. simpsoni is 3–5%, whereas intraspecific distances are 0% in five individuals of P. andysabini from two localities. 
CommentActivity: active at night

Habitat: soil, rocks, and tree trunks up to 40 cm above the ground in deciduous forests and evergreen foothill forests. 
EtymologyNamed after American philanthropist and conservationist Andrew “Andy” Sabin, known also as “Mr. Salamander,” in recognition of his life-long support of environmental programs around the world and for his passion for the preservation of amphibians and reptiles.
