Coleosoma blandum is a species of cobweb spider in the family Theridiidae. It has a widespread distribution across Asia, from India and Sri Lanka through Southeast Asia to East Asia, including China and Japan. The species has also been introduced to the Seychelles and Hawaii.[1]
The species was first described by O. Pickard-Cambridge in 1882 from a male specimen collected in Sri Lanka (then Ceylon).[2] The species was initially placed in the genus Theridion by some authors, but was transferred to Coleosoma by Levi in 1959.[3]
Two species described by Thorell in 1895 from Myanmar, Theridion acrobeles and T. conutum, are now considered junior synonyms of C. blandum.[2]
Distribution
C. blandum is widely distributed across Asia, with records from India, Sri Lanka, Bangladesh, Myanmar, Thailand, Philippines, China, and Japan.[1] In Japan, it occurs on Honshu, Kyushu, and the Ryukyu Islands (including Amami Ōshima, Okinawa Island, Iriomote Island, Ishigaki Island, and Yonaguni).[2] The species has been introduced to the Seychelles and Hawaii.[1] There are also multiple finds from Réunion.[4]
