Diagnosis. Adult female Macracantha arcuata is differentiated from those of Actinacantha globulata and Gasteracantha hasselti based on the unique long median spines that are multiple times the width of the abdomen.

Natural history. Female individuals were collected in the understorey of disturbed forests, where they resided in an inverted position at the center of their horizontal webs built directly above or near (<2 m) water bodies. The reddishorange abdominal color was observed to fade with age, turning white. The long abdominal spines of females retain some flexibility post-molt and are angled farther apart in gravid and satiated individuals. Males not observed and female populations appeared to be seasonal.

Distribution. India, China, and Southeast Asia.
