discussion
Remarks. Species-identification of these two small specimens (one in poor condition and partly covered with detritus) was not possible, although they have non-forcipate chelae (Fig. 22 A), setose pereopod- 1 basis (Fig. 22 B), and pereopods 2 – 3 propodal setation of a “ non-affinis ” group, i. e. with the inferodistal (and anaxial) spine Fig. 22 C) clearly shorter than the claw (dactylus and unguis), rather than being as long as or nearly as long (Bird & Holdich 1989). The cephalothorax is about as long as pereonites 1 – 3 combined and the length ratio of pereonites 1 – 3 is 6: 10: 15. The pereopods are slender, as are the uropods (Fig. 22 D). Additional material of this species is needed to clarify its taxonomy.
