This species inhabits the Ryukyu Archipelago of Japan and is divided into several subspecies, which have the following distribution: G. kuroiwae yamashinae on the island of Kumejima, G. k. splendens on the island of Tokunoshima, G. k. orientalis on the islands of Tonakijima, Akajima, Tokashikijima and Iejima, G. k. toyamai on Iheyajima Island, and G. k. kuroiwae on the islands of Okinawajima, Sesokojima and Kourijima (Grismer et al. 1994).
The distributional area of this species has been calculated as 1,601 km². It ranges from sea level to 450 m above sea level.
This species inhabits the leaf litter of subtropical forests in karst limestone areas (Dial and Grismer 1992). It chiefly preys at night on small invertebrates on the ground surface by switching motive and passive (ambushing) foraging tactics (Werner et al. 2004, 2006). Each adult female lays one to three clutches per breeding season (from late May to early August), and each clutch consists of no more than two eggs (H. Ota pers. comm. 2010). Hatchlings, appearing from late August to early October, usually become mature in the late breeding season of the next year or in the early breeding season in two years later (Tanaka and Nishihira 1987, 1989; H. Ota pers. comm. 2010).
A Kuroiwa’s Ground Gecko (Goniurosaurus kuroiwae), or the Okinawan Ground Gecko, is a species of lizard in the Eublepharinae subfamily. It is found only in Japan, and there are four recognized subspecies.
This species inhabits the leaf litter of subtropical forests in karst limestone areas. It is primarily nocturnal and hunts small invertebrates on the ground by both foraging and ambushing its prey.
Each adult female lays one to three clutches per breeding season (from late May to early August), and each clutch consists of no more than two eggs. Hatchlings, appearing from late August to early October, usually become mature in the late breeding season of the next year or in the early breeding season in two years later.
This species is threatened by human activities including deforestation, predation from introduced carnivores and illegal collection for the pet trade.
Large areas of the native subtropical forest on the Ryukyu Islands was cleared and converted for agriculture, and habitat degradation took place during World War II. Introduced carnivores, such as the mongoose (on Okinawajima), weasel (on Akajima), and domestic and feral cats (everywhere) find this species easy prey.
Due to these factors, G. k. toyamai is Critically Endangered, G. k. yamashinae, G. k. splendens and G. k. orientalis are considered Endangered and G. k. kuroiwae is considered Vulnerable.
Commonly called the Chinese Cave Gecko, (Goniurosaurus hainanensis), found within the captive reptile trade, though all Goniurosaurus species are not the most handleable of the Eublepharis or “Eyelid” geckos. They will tolerate being handled for short periods of time, like when removing to clean the enclosure, but they are not geckos that like being handled. Captive bred individuals may accept handling a little more, but generally, the less handling the better for this species. As these guys originate from eastern Asia, they also require a high humidity in their enclosures, and are nocturnal and secretive - so if you are looking for a gecko you can handle, interact with, is easy to look after and a joy to watch - get a Leopard Gecko.
