The Kuroiwa's ground gecko (Goniurosaurus kuroiwae) (from Japanese: クロイワトカゲモドキ/黒岩蜥蜴擬), also known as the Ryukyu eyelid gecko, Kuroiwa's leopard gecko, Kuroiwa's eyelid gecko, Okinawan ground gecko, or Tokashiki gecko, is a species of lizards in the family Eublepharidae. The species is endemic to the Okinawa Islands in the Ryukyu Archipelago, Japan.
The Kuroiwa's ground gecko is a common host for the parasite Cryptosporidium serpentis. This parasite is detrimental to the health of the gecko and causes severe gastrointestinal problems. Symptoms of a Cryptosporidium serpentis infection include: diarrhea, vomiting, and emaciation.[1]
The specific name, kuroiwae, is in honor of T. Kuroiwa, collector of the holotype.[2]
Kuroiwa's ground gecko occurs in subtropical forests in karst limestone areas at elevations below . It forages on small invertebrates in leaf litter at night.
