Reef lobsters of the genus Enoplometopus A. Milne-Edwards, 1862 (Crustacea: Decapoda: Nephropidea) from the KUMEJIMA 2009 Expedition in Okinawa, with the second record of the rare species E. chacei Kensley & Child, 1986

Two reef lobsters of the genus Enoplometopus A. Milne-Edwards, 1862, were collected during the KUMEJIMA 2009 Expedition. The first is the very rare species Enoplometopus chacei Kensley & Child, 1986, which was previously known only from the male holotype collected in the Philippines. It is found that E. chacei has two colour forms: one form with the body covered with red dots while the other form completely lacking red dots on the body. The second species collected is E. voigtmanni Turkay, 1989, and represents the first recorded male of this species. Colour photographs are provided for the two species. The characters distinguishing E. chacei and E. voigtmanni from their closest congeners are discussed.
