Idiosoma formosum

Idiosoma formosum is a species of mygalomorph spider in the Idiopidae family. It is endemic to Australia. It was described in 2018 by Australian arachnologists Michael Rix and Mark Harvey. The specific epithet formosum comes from Latin formosus (‘beautiful’), in reference to the ornate colouration of the abdomen.[1][2]
