Family : Agamidae
Species : Draco boschmai
Size (snout to vent) : up to 9 cm

Boschma's Gliding Lizard is a sun-loving species, more typically found at forest edge or in disturbed habitats such as agricultural areas or coastal districts.

The species was formerly considered to be a subspecies of Draco volans, but is now elevated to species status (McGuire and Kiew, 2001).

Its patagium (wing membrane) is greyish-brown with lighter and darker mottling. The gular flag of the male is triangular in shape, and bright yellow in colour with darker mottling towards the base. The gular flag of the female is small and bluish. The species exhibits significant variation in colouration and patterning on different islands, however.

Draco boschmai reportedly has a somewhat longer tail than Draco volans.

Its diet probably largely comprises ants, in common with many other species of gliding lizard.

Draco boschmai occurs in the Nusa Tenggara (= Lesser Sunda) islands of Indonesia, ranging from Lombok in the west, through Sumbawa, Komodo (and possibly Rintja), Sumba, and Adunara to Flores in the east. 

To the west of Lombok (i.e. Java and Bali), the species is replaced by the closely-related Draco volans, and to the east of Flores (i.e. Timor and other islands) the species is replaced by the closely-related Draco timoriensis.
