ABSTRACT: Recent observations and museum records of the Mediterranean gecko (Hemidactylus turcicus) from Tennessee were examined to determine its known distribution in the state. At present, only twelve vouchered records (six specimens and six photographs) exist. The first reported sighting of this non-native, nocturnal species occurred in Memphis in 2007 and, since that time, five additional sightings have been reported from various locations within the city and surrounding suburbs. Observations of multiple geckos from the cities of Martin, LaVergne, Memphis, Maryville, Nashville, Murfreesboro, and at the Big South Fork National River and Recreation Area in Scott County indicate a wider distribution of this species across the state. The presence of adult and juvenile individuals in surveys of these localities indicate that the species is reproducing, and it therefore seems likely that these are established populations. Since little is known about the potential impact of this species on native lizard populations, continued monitoring is warranted.
