Introduction

The Petalophthalmidae are a small, mainly deep water family of six genera and about 32 species (Price et al. 2001). Only one genus and species is known from Australian waters. Müller (1993) and Price et al. (2001) catalogued the family.

Diagnosis

Rostrum obtuse or broadly rounded. Eyes reduced (flattened to one or two leaf-like forms). Mandible lacinia mobilis reduced or absent, spine row reduced to a single spine. 1st maxilliped exopod absent. 2nd thoracopod developed as a maxilliped, exopod absent (as in Petalophthalmus) or well developed (as in Hansenomysis). Marsupium composed of seven pairs of oostegites. Uropod endopod statocyst absent; exopod with distal articulation, outer margin entire (as in Petalophthalmus) or outer margin with slender and robust setae (as in Hansenomysis).
