Remarks. Together with D. grisea, Figueroa et al. (2020) reviewed all records of D. olivacea from Singapore and added a new record from Springleaf Forest of an individual basking at the top of a coconut tree on 13 June 2018 ( Fig. 14E View FIGURE 14 ). Unlike D. grisea , D. olivacea has been known from Singapore for a long time ever since Flower (1896) examined a specimen Ridley collected from a coconut tree in Geylang. Dasia olivacea is notably rarer than D. grisea , having only been reported nine times. Between publication of the third (Sworder 1925) and fourth records (Lim 1990), 65 years elapsed ( Table 2 View TABLE 2 ). In addition, there are two specimens deposited at CAS that were collected by Herre in 1937, and two previously unpublished records by Cross (2020n) from Changi in 1945 that were recently published ( Lim 2020). Adding these four records brings the total number of records of D. olivacea in Singapore to 13. Figueroa et al. (2020) perceived that D. olivacea may be less common than D. grisea because it is being outcompeted by D. grisea , or perhaps because D. grisea has become more successful by adapting to using large exotic trees that tend to contain many cavities or exfoliating bark useful for evading predators.
