Remarks This species was regarded as Endeis meridionalis in Sabroux et al. (2019b) despite the shorter distance between the lateral processes, and the absence of kinked femorae in the Martinique material. The specimens also resemble E. spinosa as drawn by Marcus (1940) , but this species was represented in quite different fashions, with a variable shape of the proboscis, distance between the lateral processes, etc. ( Hedgpeth 1948 ; Child 1992b ; Munilla & Soler-Membrives 2014 ). Since the original description provides little information, and because of the inherent difficulties in identifying species of Endeis , the status of this morphospecies remains doubtful; therefore, we refrain from describing it as new species. Most of the specimens were found on the Atlantic coast, although three were collected at Pointe Diamant on the Carribean coast. Distribution Mostly recorded from the Indian Ocean ( Somalia , Réunion , Mauritius (?), Madagascar , India , Malaysia , India , Western Australia) and the Red Sea; also reported in the Pacific ( Japan , Moorea, Fiji islands ), in the Eastern Atlantic ( Cape Verde ) and in the Caribbean ( Curaçao ). Depth range 0– 90 m .
