Figure 1

Representative crustacean hosts parasitized by epicaridean isopods.

A) Synalpheus fritzmuelleri Coutière, 1909 (Caridea: Alphaeidae) from Caribbean Panama, with unidentified bopyrid, possibly Bopyrella harmopleon Bowman, 1956 (known from this host in Venezuela); B) Miopontonia yongei Bruce, 1985 (Caridea: Palaemonidae) from Bali, Indonesia (new host locality record, previously known from Australia and southern Japan), with unidentified bopyrid (host previously not recorded with any bopyrid); C) Lebbeus grandimanus (Bražnikov, 1907) (Caridea: Hippolytidae) from North East Pacific, with unidentified bopyrid, likely Bopyroides hippolytes Krøyer, 1838 (known from this host in the North East Pacific); D) Aliaporcellana cf. suluensis (Anomura: Porcellanidae) from Fiji possibly with Allorbimorphus haigae Bourdon, 1976 (known from this host in Indonesia but this Fijian would represent a more than 5600 km range extension for this bopyrid); E) Gnathophyllum americanum Guérin-Méneville, 1855 (Caridea: Gnathophyllidae) from Japan with unidentified bopyrid, possibly Schizobopyrina bombyliaster Williams & Boyko, 2004 (known from this host in Tonga); F) Hemigrapsus nudus (Dana, 1851) (Brachyura: Varunidae) from Coos Bay, Oregon with carapace removed to show the entoniscid Portunion conformis Muscatine, 1956 (arrowhead); G) Lithoscaptus helleri (Fize & Serene, 1957) (Brachyura: Cryptochiridae) from Indonesia with unidentified bopyrid in left branchial chamber (host previously not recorded with any bopyrid); H) Alpheus sp. aff. paracrinitus Miers, 1881 (Caridea: Alpheidae) from Fiji with Faba sp. (Cryptoniscidae) attached to ventral surface (host not previously recorded with any epicaridean).
