 Issued from : M.A. Jimenez Alvarez inBolm. Zool. Univ,. S. Paulo, 1984, 8. [p.95, Figs.1-5] Male (28°36'S, 47°55'W): 1-2, habitus (dorsal and lateral, respectively); 3, forehead with rostrum (lateral); 4, A1; 5, A2. Nota: Cephalon and 1stpedigerous segment partially fused (dorsal visible suture almost complete, 4th and 5th thoracic segments almost completely fusd, ending in potero-lateral projections, acutely pointed and slightly asymmetrical ; the left, a little longer, overreaches the posterior margin of genital segment. Urosome 5-segmented. Proportional length of segments and caudal rami 21.7 : 20.0 : 16.7 : 15.0 : 26.7 = 100. Genital segment slightly asymmetrical. Anal sefment wery reduced and only ventrally visible. Caudal rami with 1 short lateral seta and 3 terminal setae. Left A1 24-segmented, reaching the caudal rami ; segments bearing thick sensory setae up to 13th segment included, and, the thinner ones up to the end and other very thin setules. Right A1 lost. A2 2nd basipod with 2 setae ; exopod and endopod almost equal in length ; 2nd endopodal segment with 5 subterminal and 4 terminal setae on the lateral margin ; externally there is a group of very small spines.

 Issued from : M.A. Jimenez Alvarez inBolm. Zool. Univ,. S. Paulo, 1984, 8. [p.103, Figs.6-12] Male; 6, Md (palp); 7, Mx1; 8, Mxp; 9, P1; 10, P2; 11, P3; 12, P5. Mandibular palp with well developed basipod and 1 internal marginal seta. The two-segmented endopod is short. The exopod has 1 long thick seta on each of its four first segments, the last has 2 setae. The gnathobase was not found in this specimen. Mx1 reduced with 3 setae on the 1st external lobe, 9 setae on the exopod ; no setae on the 1st internal lobe, 2setae on the other internal lobe and 6 fine setae plus a very long one on the fused 2nd basipod and endopod. 1st basipod of Mxp without setae ; 2nd basipodal segment with 2 long plumose setae and 1 very shot.. The 1st to 5th endopodal segments bear respectively 5 : 3 : 4 : 3 : 4 setae. P5 asymmetrical and very big. Left leg, shorter than the right with the basipods and the 3 segments of the exopod long, the last segment the shortest and bearing some setae ; endopod reduced, 1-segmented in both legs.. The 1st segment of the exopod of the right leg is much longer than the second, and this is curved with a bulge on the lateral internal margin.
