PERICLIMENES THERMOHYDROPHILUS HAYASHI

& OHTOMI, 2001

Type locality: Pacific Ocean, southern Japan, Kagoshima Bay , hydrothermal vent fields, associated with Lamellibrachia satsuma , 90–100 m.

Known range: known only from hydrothermal springs at the eastern end of Kagoshima Bay , Japan, from 90– 115 m ( Hayashi & Ohtomi, 2001) .

Material: type locality, Shinkai 2000 dive 980, 30 September 1997, NFU 530-2-2367 (holotype, ovigerous female), NFU 530-2-2368 (paratypes; 11 ovigerous females, 1 male).

– Kagoshima Bay, Dolphin 3K dive 340, 1 September 1997, 31 39.5′N, 130 48.2′E, 97 m; NFU 530–2-2369 (paratypes, 2 ovigerous females) .

– Kagoshima Bay , northern part, 105 m, 20 April 2001, NFU 530-2-2370 (paratypes, 4 males, 1 female) .

Remarks: Hayashi & Ohtomi (2001: 160) reported ‘considerable numbers of unusual shrimps... found in the tube worm [ Lamellibrachia satsuma ] colonies at depths of about 100 m’, all of which belonged to their new species, Periclimenes thermohydrophilus , the first palaeomonid shrimp reported from a hydrothermal vent field. The species was always found in or around colonies of L. satsuma and other unidentified polychaetes (K. Hayashi, pers. comm.). The relatively large number of specimens allowed them to make notes on fecundity and natural history; colour photographs of the species were also provided.
