Tharpyna diademata L. Koch, 1874 (diamonded Tharpyna)

A small, bark-dwelling crab spider, the female to about 4mm, the male smaller, to 3mm. The body is very dark, essentially black, flattish, with a somewhat roughened surface, and four distinctive white marks on the abdomen. The legs are pale brown to clear with white rings just above the patellas. They live underneath the loose bark where they prey on small insects including ants and weevils. The range is at least from eastern Australia Victoria to Cape York. This spider was named by Koch in 1874 in his description of a male and female from Lord Howe Island. Diademata means crowned.
