Migas plomleyi, also known as Plomley's trapdoor spider, is a species of tree trapdoor spider in the Migidae family. It is endemic to Australia. It was described in 1989 by Australian arachnologists Robert Raven and Tracey Churchill.[1]
The species occurs in Tasmania.[1] It is only known from the Cataract Gorge–Trevallyn area, in the suburbs of Launceston in the north of the state. It prefers sheltered, humid sites where the ground is covered with a lush growth of lichens or mosses. Only female specimens are known; it has rarely been collected, and is listed as Endangered under Tasmania's Threatened Species Protection Act 1995.[2]
The spiders construct individual parchment-like silk chambers about 2 cm across, on the ground or on moss-covered rocks, the entrances to which are closed by thin trapdoors or lids.[2]
