Males: fragmented, body length ca 47 mm; maximum midbody diameter 2.6 mm.  COLOR. Body color faded, but apparently prozonites brownish, metazonites with a posterior brown band; head, collum, and legs lighter brown.  HEAD. Antennae long ( Fig. 164F), just reaching back to end of ring 6 when extended dorsally; antennomeres elongated; relative antennomere lengths 1<2<3>4=5=6>7. Mandibular cardo with ventral margin narrow. Ommatidial cluster well-developed, elliptical; ca 45 ommatidia in 6 rows.  BODY RINGS. Collum with lateral lobes broadly rounded, with ca 12 striae ( Fig. 106A). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae below ozopore. Anterior sterna in midbody rings subrectangular, without transverse striae.  FIRST LEG-PAIR OF MALES. Coxae ( cx) elongated (as long as the sum of remaining podomere lengths), subrectangular, with the base arched, densely setose ( Fig. 107A); prefemoral process ( prf) thinner than half the prefemur, subcylindrical, densely setose up to its median region ( Fig. 107B); remaining podomeres with setae along the mesal region.  SECOND LEG-PAIR OF MALES. Coxa ( cx) large and rounded; penis ( pn) located at proximal region, rounded, extended basally ( Fig. 107C); prefemur compressed dorsoventrally; remaining podomeres setose.  GONOPODS. Gonocoxa ( gcx) subtriangular, short ( Fig. 108D); with rows of papillae mesally. Seminal groove ( sg) not visible on mesal cavity. Shoulder ( sh) rounded. Telopodite ( tp) large, but not as wide as gcx; solenomere ( sl) with apicomesal process ( amp) rounded; ectal process absent; salocated at mesal portion, slightly visible apically. Internal branch ( ib) short, subtriangular, with horizontal plate; setae apparently starting at midlength of ibexceeding seminal region of sl( Fig. 108D).    Distribution Known only from the typelocality Carmen de Patagones, Buenos Aires, Argentina( Fig. 186). 4101309964 R R. von Ihering Argentina -40.783234 Carmen de Patagones 1 -62.982822 68 69 MZSP 242 1 1 Buenos Aires holotype
