Eiconaxius sibogae (De Man, 1925)

(Fig. 1 e–g)

Axius (Eiconaxius) sibogae De Man 1925a: 218 .—De Man 1925b: 4, 15, 34, pl. 2 fig. 4. Eiconaxius sibogae .—Sakai & de Saint Laurent 1989: 23.— Sakai 1992: 163, fig. 6. Eiconaxiopsis sibogae .— Sakai 2011: 295 –296, fig. 58.

Material examined. 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 .
