Terrestrial in moss on windward side of ridge. Size. 8.5 mm . Diagnosis ( male ). With the characters of the genus. Remarks. According to Miyamoto & Morino (2004) Laniporchestia lanipo belongs to Platorchestia group 3. Unfortunately a female was illustrated and described. Only gnathopods 1 and 2 were illustrated for the male. Although the author’s claims that all other male characters are like the female, this may not account for subtle differences in pereopod 7 for instance. We have been able to diagnose the genus on non-incrassate characters except for the male gnathopod 1. Distribution. Hawaii , Oahu ( Richardson 1991 ).
