Remarks. Gekko cf. kuhli was thought to have been first discovered in Singapore on 18 October 2002 when it was found on PT ( Lim 2006), but new evidence presented by Lim et al. (2019) pushed the date of discovery back to 1868 when Spooner collected specimen MNHN-RA-0.1692. Presumably, specimen MNHN-RA-1868.246 was also collected by Spooner as it is dated 9 December 1868 (Roomaaker 2021). The specific locality for both specimens are unknown; thus, it remains uncertain if G. cf. kuhli ever existed on mainland Singapore. Flower (1899b) alluded to G. cf. kuhli on mainland Singapore, possibly BTNR, when he compared the presence of several higher elevation species from Peninsular Malaysia also occurring in Singapore, but it is unknown whether he was referring to his own observations, Spooner’s specimen, or some other source. Lim et al. (2016) stated that the encounter rate for G. cf. kuhli on Pulau Tekong is 2.71 individuals per km-1. Molecular analyses revealed high genetic structuring suggesting G. cf. kuhli is a species complex comprising five to nine species with populations from Peninsular Malaysia split into three divergent clades ( Brown et al. 2012). It is likely that Singapore’s population on PT will be associated with the southeastern Peninsular Malaysia and Seribuat Archipelago clade.

Occurrence. Restricted to PT, also known from one specimen from Singapore Island predating 1868. Uncommon.

Singapore conservation status. Critically Endangered.

Conservation priority. Highest.

IUCN conservation status. Least Concern [2021].
