Introduction

This family comprises a single genus and species, Lomis hirta (Lamarck, 1818), known as the Hairy Stone Crab and found under rocks in southern Australia. The use of the name Lomisidae is favoured here because Lomis appears not to be derived from a classical stem, and therefore the entire generic name should be used as the stem of the family name, as it was in the first family-level usage of Bouvier. As, currently, both Lomidae and Lomisidae are used (c.f. Cormie (1993) and McLauglin (1983)), ICZN Article 29.5 cannot be invoked to preserve either spelling over the other.

The phylogenetic position and family status of this group have been the topic of some discussion, especially by Pilgrim (1965), and McLaughlin (1983). The zoea was first described by Cormie (1993).

Diagnosis

Crab-like anomuran with symmetrical, flattened, subtriangular body. Ocular peduncles broad and flat, cornea inserted laterally; ocular acicles absent. Epistome armed with spine. First pereiopods forming short, broad, flat chelae; second to fourth pereiopods ambulatory; fifth pereiopods reduced, carried in branchial chamber. Third maxillipeds separated at base. Antennal peduncle with five segments plus supernumerary segment for antennal peduncle. Abdomen folded under body, first abdominal somite visible dorsally; female with non-spatulate uropods, male uropods vestigial; telson undivided. Male gonopods present; female first pleopods present. Fourteen pairs of gills pesent.
