Tail depressed, flat inferiorly, with sharp denticulated lateral edge, covered above with uniform small granules, below with a median series of transversely dilated plates. Limbs moderate, depressed; digits strongly dilated, about half-webbed, inner well developed; 3 to 6 lamellae under the inner, 7 to 9 under the median digits.

They are also introduced in Florida (Pinellas, Alachua, Lee, Broward, and Miami-Dade counties) in the USA.[5]

These geckos are frequently found in the pet trade, including corporate chain stores, usually identified only as "house gecko". While there are other species of gecko available under the same common name, the Cosymbotus platyurus is easily identified by the flaps of skin along its sides, making them resemble a miniature flying gecko (genus Ptychozoon). They are easily maintained in a terrarium with frequent misting and insect prey, but they are not easy to handle. Also, herpetoculturists often use this species in addition to anoles as a feeder lizard for some species of snakes, especially Asian green vine snakes (Ahaetulla prasina).
