Descriptive notes: Male, see description in Hoffman (1988a: 324, figs. 1-7). Size: Body length 102-110 mm, vertical midbody diameter 4.8-5.2 mm., 65-72 podous body rings. The examined specimens from Mato Grosso resemble those from Nova EsperanÇa by general somatic characteristics, in particular the prominent lateral end of collum ( Fig. 2A, C) and the large distal edges of the paraprocts ( Fig. 2B, D). Males agree in having densely setose prefemoral process (pfp) in first leg-pair ( Fig. 6 A-B); proplica (pp) with lateral lobe expanded, telopodite (tp) with lamellar expansion, and elongated antetorsal process with a complete 360° torsion ( Figs. 4 A-B; 5A-F). Ventral pads on postfemur and tibia on midbody legpairs ( Fig. 4D). Females with nonsexual characters as in males ( Fig. 2 C-D).

Distribution: The species was known only from its type locality Nova EsperanÇa, Rondônia; now also known in the state of Mato Grosso (Madeira, Xingu-Tapajós, and Cerrado provinces) (up to ca. 2,000 km. from Nova EsperanÇa).
