Remarks. Lepidodactylus lugubris is a parthenogenetic species comprising several genetically distinct diploid and triploid clonal lineages that originated through hybridisation between two species likely at Arno Atoll in the Marshall Islands (Radtkey et al. 1995). Native to several of the Pacific Islands, L. lugubris now boasts a global distribution as it has been transported all over the world via human means, where it can easily establish itself by way of parthenogenesis (Lapwong & Juthong 2018). The first record of L. lugubris from Singapore was a specimen Sworder (1924a) found under loose bark on a tree at Pulau Hantu. The next record of L. lugubris from Singapore, and the first record for the mainland, came 56 years later (Table 2) when Chou et al. (1980) mentioned it was found in mangroves. Lepidodactylus lugubris again went unreported for another 13 years until one was found in the boot of a car in Newton of May 1993 (Lim 1993a). Museum records all post-date this specimen. This lead Lapwong & Juthong (2018) to believe that L. lugubris was introduced into Singapore around the early 1990s.
Using photographs from iNaturalist, Lapwong & Juthong (2018) identified the variant occurring in Singapore as “clone A” from Ineich (1988). They also mentioned that clone C also occurs in Singapore referencing Fig. 4.11 in Ang et al. (2012), but suggested that it is not as common as “clone A” since it appears less tolerant of rural areas. A preliminary inspection of assorted photographs shows that both clones occur in Singapore, and that there appears to be no partitioning between the clones in habitat use. Clearly, a detailed studied is required to identify all the clones occurring in Singapore and to assess their relative population sizes. Lepidodactylus lugubris has only been reported eight more times in the literature, leading Baker & Lim (2012) to classify it as rare. As L. lugubris occupies the same niches as Singapore’s other “house” geckos, its perceived uncommonness may be due to it being outcompeted given its smaller size. Nonetheless, we do not find L. lugubris to be rare in Singapore.
