Macracantha is a genus of Asian Orb-Weavers Spiders recognized as containing a single species Macracantha Arcuata and is a known for the extremely long curved spines on the abdomens of female members of the genus and is found in India and China thru South East Asia to Borneo
Female long-horned orb-weavers have tough, shell-like abdomens armed with three pairs of spines. The spectacular middle (median) spines project upward and outward, curving in toward each other along their length. They are up to three times as long (20-26 mm) as the abdomen is wide (8-9 mm). The front (anterior) and rear (posterior) spines are short, relatively inconspicuous, and roughly equal in length
The upper surface of the female abdomen ranges from yellow to red or even white or black and is marked with black sigilla while the ventral surface of the abdomen bears yellow or orange marks, and the median spines can show a bluish iridescence
The male of the species measures only 1.5 mm, with stout, conical spines
