Asian Spinybacked Orbweaver
Thelacantha brevispina
Thelacantha (Asian spinybacked orbweaver) is a genus of orb-weaver spiders containing the single species, Thelacantha brevispina. It was first described by A. W. M. van Hasselt in 1882, and has been found in Australia, Madagascar, the Indian subcontinent, and Southeast Asia, as well as parts of Japan. It has also been introduced into Hawaii. T. brevispina is closely related to those in the genus Gasteracantha and was briefly synonymized with it in 1859, but revalidated in 1974. Saito described three other Thelacantha species in 1933, which were later synonymized with T. brevispina.

Most have two large white spots on the upper surface of their abdomens, which are otherwise mottled with black, brown, and white patterns.
