FIGURE 2. Precloacal regions of six Sundanese and Sulawesi species of Cyrtodactylus showing differences in the expression of a precloacal depression in adult males. (A) C. pubisulcus (AMNH R111889) possessing a slit-like precloacal groove, with the pore-bearing scales sunk deeply into the depression and not visible. (B) C. klakahensis (SMF 22476; holotype) possessing a slit-like precloacal groove, with the pore-bearing scales sunk deeply into the depression and barely visible. (C) C. fumosus (BMNH 1896.12.9.3) possessing a precloacal groove, with the enlarged pore-bearing scales arranged in the shape of an inverse 'Y' with the groove broadening posteriorly. (D) C. baluensis (MCZ.Herp R-39036) possessing a precloacal pit, with the porebearing scales from the left and right side of the posterior-most precloacal scale series arranged in the shape of an inverse 'V' and widely separated from each other, creating a depression in the form of an acute triangle. (E) C. consobrinus (MCZ.Herp R- 102031) possessing a precloacal pit in the form of an obtuse triangle. (F) C. wetariensis (AMNH R32165; holotype) lacking a precloacal depression.
