Abstract

A new species of hermit crab, Strigopagurus fragarchela, is described from the continental shelf off south‑east Queensland. It can be separated from congeneric species by characters such as chelae shape, armature, and stridulatory plates; pereiopod shape and armature; and characteristic live colouration. Four endemic species are now known from Australia. A key is provided to all six species in the genus, and all are illustrated for easy comparison. New records of S. bilineatus Forest, 1995 are recorded, increasing its known southerly distribution.
