a larger cheliped, dorsal view; b same, ventral view; c smaller cheliped, dorsal view; d same, ventral view; e right second pereopod, lateral view; f same, propodus and dactylus
, lateral view.
The gap between the dactylus
and propodus of the cheliped is wide in A.
2, I-M) Not chelate; 1st pereiopod of 4 spines in basal endite; 3 strong and two weak spines in dactylus
of 1st pereiopod; general shape unchanged from 2nd pereiopod through 5th pereiopod.
Outer maxillipeds placed nearly longitudinally; merus and ischium fused, a demarcation line sometimes visible between them; palpus three segmented, carpus slightly longer than subtrapezoidal propodus, dactylus
articulated disto-medially on ventral margin of subtrapezoidal propodus, overreaching it considerably.
Pereopod 1 dactylus
and unguis much shorter than in female.
The cheliped (and in fact all the legs) comprise seven segments, coxa, basis, ischium, merus, carpus, propodus and dactylus
in that order, not four as stated.
Large chela with dactylus
shorter than fixed finger.
2A, C), the similar morphology of pereiopods 3-5 but the distinctly different dactylus
of pereiopod 2, the well developed suture on both uropods, and other characters of the genus (see Goy and Provenzano 1979; Alvarez et al.
Our focus is on the mandibular palp, the medial rim of the basis of maxilla 1 and maxilliped 1, the propodus and dactylus
of the endopod of maxilliped 2, and the dactylus
of the endopod of maxilliped 3.
