“…Likewise, traits based on ratios (e.g., head length / head height; Rösler et al 2011) were not utilised, as tokay geckos continue to grow beyond sexual maturity (Kurniati and Phadmacanty 2022), and it is unknown whether these ratios remain constant once sexual maturity is reached. Body mass and total length were not included in the analysis as both can be impacted by caudal autotomy, which is common in tokay geckos (Nurhidayat et al 2020; pers. obs.).…”

The red-spotted tokay geckoGekko gecko(Linnaeus, 1758) is a widely distributed Asian gecko that has established outside of its native range in Florida, USA. This study used genotypic and phenotypic data to determine whether multiple, distinct forms of red-spotted tokay gecko are present in Florida, specifically the morphologically distinct "G. g. gecko" and "Form B". Two discrete mitochondrial clades (ND2) were identified in Florida tokay geckos, the native range distributions of which were found to correspond closely with the native ranges ofG. g. gecko(the Malay Archipelago) and Form B (mainland Asia), respectively. Furthermore, each mitochondrial clade was non-randomly associated with a separate nuclear (RAG-1) clade, supporting the existence of two discrete genotypic lineages, representative ofG. g. geckoand Form B. Both lineages were detected in Florida, and population-level morphological structure was non-randomly associated with genotype, confirming a genotype-phenotype link. Multiple lines of evidence thus indicate the introduction of both forms of tokay gecko to Florida, where hybridisation likely also occurs. The link between morphological Form B and a unique genotypic lineage also indicates the existence of a tokay gecko taxon distinct from the recognised subspeciesG. g. azhariMertens, 1955 andG. g. gecko(Linnaeus, 1758).
