( Figs 1 i–l)

Iconaxiopsis consobrina .— Balss 1925: 211, fig. 15.

Eiconaxiopsis heinrichi Sakai, 2011: 291 –295, figs 55–57 (not fig. 56D).

Type material. Holotype: Indonesia, west coast of Sumatra, 677 m (Deutsche Tiefsee Expedition trawl stn 198), 2 Nov 1899, ZMB 19345 (male, 8.0 mm).

Remarks. Sakai based his new genus Eiconaxiopsis and his new family Eiconaxiopsididae partly on the unusual form of the dactylus of pereopod 3 that he illustrated and described as ‘tapering and pointed distally’ ( Sakai 2011: 294, fig. 56D). Examination of the holotype revealed that pereopods 3 and 4 possess spatulate dactyli with a single marginal row of spiniform setae plus few on the lateral face as is typical of many species of Eiconaxius ( Figs 1 i, j). Sakai’s illustration is of a pereopod from another animal, not in this genus. The species is one of only five, listed above, known to possess a male pleopod 1 ( Fig. 1 k).
