Remarks. Poore and Griffin (1979) provided only a short description and simple figures. Here, the antennae, chelipeds, terminal articles of pereopods 3 and 4, male pleopods, telson and uropod are figured. The species is notable for the setose thoracic sternite 7 and ventroposterior surface of the coxa– ischium of pereopod 5, a feature diagnostic for the genus (fig. 26b). The antenna bears a free scaphocerite, longer than broad, with a rounded apex (fig. 26a). The exopod of maxilliped 3 typically reaches the middle of the merus but is shorter on smaller individuals. While the fixed finger of the minor cheliped is shorter than the dactylus in most individuals it is almost as long in one male. The propodus of pereopod 3 is suboval, little longer along its upper margin than its greatest width, and densely setose on its lateral face. The propodus of pereopod 4 is elongate-oval, 1.5 times as long along its upper margin than its greatest width, with a distal long spiniform setae on the lower margin, and densely setose on its lateral face. The male pleopod 1, overlooked by Poore and Griffin (1979), has a shorter second article with an apical notch (fig. 26g). The peduncle of the male pleopod 2 is longer than broad; the appendix interna is short and lacks hooks; no appendix masculina is present (fig. 26h). The appendix interna on the endopod of pleopod 3 is triangular, longer than broad, emerging by about half its length (fig. 26j). The uropodal endopod is oval, 1.8 times as long as wide, with marginal setae; the exopod is 1.6 times as long as wide, with short spiniform setae along its apical margin, with a well-defined dorsal plate with c. 6 short spiniform setae and many longer setae (fig. 26f). A dorsal oval, cardiac prominence and cardiac sulcus are all absent; all known material is in NMV (cf. contradictory statements and figures in Sakai, 1999, and Sakai, 2011).
