Diploderma polygonatum, also known as Ryukyu japalure and Okinawa tree lizard, is a species of lizard found in the Ryukyu Islands and Taiwan.[1][2] It is diurnal and arboreal.[3] An adult male Diploderma polygonatum measures "61 mm. from snout to vent, and 152 mm. from vent to tip of tail; total length 213 mm."[4] The splenial of this lizard is short, as is that of Trapelus agilis.[5] The lizard is also closely related to Diploderma swinhonis.
