“…Millions of tokay geckos are harvested annually, both for the Asian traditional medicine trade—where they are used in the treatment of ailments including AIDS and asthma (Bauer 2009, Nijman et al 2012a, Nijman et al 2012b, Caillabet 2013, Nijman and Shepherd 2015)—and for the international pet trade (Nijman et al 2012b, Casey et al 2015). Despite these native-range declines, non-native tokay gecko populations are now established in Curaçao (Behm et al 2019), Florida, USA (King and Krakauer 1966, Krysko et al 2019), Martinique (Henderson et al 1993, Breuil 2009), Mexico (Villalobos-Juárez et al 2022), Puerto Rico (Romero Cordero 2021), and likely Belize (J Meerman, pers. comm.)…”

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).

First records of the Tokay Gecko, Gekko gecko (Linnaeus, 1758) (Squamata, Gekkonidae), in Mexico

Abstract: We report the first records of the invasive Tokay Gecko, Gekko gecko (Linnaeus, 1758), in Mexico, based on the discovery of five specimens from Reynosa, Tamaulipas.
