Anelosimus spp. which actually include Theridion (Tobesoa) theridioides, some Anelosimus and an unknown genus

A number of medium-sized Theridiids, usually between 2-4mm, sometimes larger, may belong to the genus Anelosimus, known elsewhere but not yet recorded for Australia. Dr Greg Anderson has been working with Dr Helen Smith (Australian Museum) on some subfamilies of Theridiids and suspects that many undescribed species may well be put into Anelosimus. When they are described we will know their species names.
