Platorchestia Bousfield, 1982

Remarks. Miyamoto & Morino (2004) established three groups within Platorchestia based on the presence or absence of sexually dimorphic characters. Platorchestia (group 2) is based on having a sexually dimorphic second antenna (incrassate) and no sexual dimorphism in pereopods 6 or 7. According to Miyamoto & Morino (2004) Platorchestia (group 2) contains two species: P. ashmoleorum Stock, 1996 and P. monodi ( Mateus, Mateus & Afonso, 1986) . There are additional species of this distinctive group in the Australian Museum collections from the western South-Pacific islands of Fiji, Hawaii, Tonga and the new species P. smithi sp. nov., described below from eastern Australia.
