Bismarck Sea, E of Karkar I. , 04°34'S , 146°17'E , 411–430 m ( PAPUA NIUGINI stn DW3973) , MNHN IU-2014-10397 (male, 6.4 mm ). Point SE of Manus I., 02°10'S, 14°717'E, 300 m (BIOPAPUA stn CP3693), MNHN IU-2014-10399 (female, 10.0 mm)—selected from c. 50 specimens in MNHN. Remarks . Sakai (2011) designated and reillustrated a lectotype , one of two syntypes . He placed the species in Eiconaxiopsis , presumably on the basis of the possession of a male pleopod 1 which he said to be ‘trisegmented’. It is a single article with a thin blade-like apex in the specimen illustrated here ( Fig. 1 g). He illustrated the dactyli of pereopods 3 and 4 as typical of Eiconaxius , not as illustrated for E. heinrichi , the other species he included in Eiconaxiopsis .
