Periclimenaeus species (Crustacea: Decapoda: Pontoniinae) from Hawaii.

Two specimens of an undescribed species of pontoniine shrimp of the genus Periclimenaeus Borradaile 1915 from Maui Island, Hawaiian Islands, are described and illustrated, raising to three the number of species known from the Hawaiian Islands. The new species is remarkable for the greatly reduced molar process and sharp lateral cutting edge on the major second pereiopod dactyl and most closely resembles P. tchesunovi Ďuriš, 1990. Host animals not identified. Periclimenaeus devaneyi Bruce, 2010 also has its colouration described for the first time.
