Richalpheus palmeri Anker & Jeng 2006 (Figs. 5, 6) Richalpheus palmeri Anker & Jeng, 2006: 381, figs. 1–6 Not Richalpheus palmeri. — Anker 2010: 34, figs. 7, 8 [= R. alpheoides sp. nov.] Material examined. 1 female (cl 5.2 mm), OUMNH.ZC. 2011-06-023, French Polynesia, Moorea, inside lagoon, ray feeding site in front of Hotel Inter-Continental, shallow sand flat, about 1.5 m, A. Anker, C. Glasby, V. Liao, 0 2.12.2010 [fcn BMOO 16077]. Description. See Anker & Jeng (2006). Colour in life. Semitransparent, whitish, with pinkish tinge, and with reddish chromarophores on antennular peduncles, posterior abdominal somites and tail fan; chelipeds hyaline-white (Figs 5, 6). Type locality. The Philippines, Bohol, Panglao Island. Distribution. Indo-West Pacific: presently known only from the Philippines (Bohol, Palawan) and French Polynesia (Moorea) (Anker & Jeng 2006; present study; A. Anker, pers. obs.). Ecology. Shallow sand flat, about 1.5 m, in burrow of unknown host. Remarks. The present specimen agrees perfectly with the holotype of R. palmeri as described and illustrated by Anker & Jeng (2006) and is the first known specimen of R. palmeri in Moorea and French Polynesia. The previous record of R. palmeri from Moorea (Anker 2010) was re-assigned to R. alpheoides sp. nov. (see above). Thus, two species of Richalpheus occur sympatrically in French Polynesia, viz. R. palmeri and R. alpheoides sp. nov.
