Achaeus curvirostris (A. Milne-Edwards, 1873) View in CoL

Material examined. Inside of Gesodokkuru Reef , off Arumonogui, Babelthuap I., Palau Is., dredged, ca. 20 m in depth; 1 ovig.♀ (cb 6.5×cl 9.1 mm), NSMT-Cr 30955; July 13, 1980; K. Baba leg.

Remarks. Stenorhynchus fissifrons Haswell, 1879 , Achaeus tenuicollis Miers, 1886 , and A. elongatus Sakai, 1938 , were synonymized with A. curvirostris by Griffin and Tranter (1986). This long-neck species is characteristic in having the carapace with the tuberculate mesogastric and cardiac regions, the preorbital and supraorbital spines, and the sickle-shaped dactyli of the last two ambulatory legs.

Distribution. Widely distributed in the Indo-West Pacific from Japan to Australia and New Zealand, and further to the western Indian Ocean, with bathymetric records from 3 to 165 m. New to the Palau Islands.
