Hemidactylus angulatus Hallowell, 1852

Vouchers: NMK-380L/1–3 (field nos. SK16 1110, SK 1116, SK16 1055)

Localities: KF (B), TBI, petrified forest

Remarks: This is a fairly large gecko that is widespread in Kenya, occurring south to Tanzania, north to Sudan and west to Senegal, and occupying a variety of dry and mesic habitats ( Spawls et al. 2018). It can be distinguished from H. ruspolii and other Hemidactylus by small granules covering the upper surface of the snout rather than large and keeled granules, heterogeneous dorsal scales with small granular scales interspersed with rows of large, keeled, and mainly oval tubercles, and males with a series of 20–46 preano-femoral pores interrupted mid-ventrally ( Fig. 4E ). Three individuals were found over the course of our study, and all of them were associated with rocks or anthropogenic structures/ houses. This taxon might actually represent a species complex (the type locality is in Gabon), and extensive molecular analyses are necessary to resolve its status. One gravid female carrying eggs was collected on 7 April 2017.
