BRIEF DESCRIPTIVE NOTES (after Attems [1898, 1938]). Length 56 mm, width of pro- and metazona 4.0 mm and 6.0 mm, respectively. Coloration yellowish brown; head, sides and anterior margins of metazona castaneous brown; antennae, lateral rims of paraterga and legs yellow; prozona yellowish with a brown axial line. Paraterga unusually narrow, but strongly rimmed, both anterior and caudal corners mostly rounded, caudal corners on rings 4–7 rectangular, thereafter dentiform; lateral rim on rings 1–4 finelY serrate. Epiproct simple and finger-shaped, directed slightlY dorsad. HYpoproct with a small apical tooth between both thick setigerous knobs. ♂ legs ventrally with all prefemora but two last pairs carrying apical swellings, and tibiae with very large apical chelae, tarsi being unusuallY small and slender ( Fig. 8A ). ♂ coxae 1–3 nearlY in touch medially, each coxa 3 apically with a slender, straight and densely setose ventral process.

Gonopods ( Fig. 8B–E ) with prefemoral process (PfP) considerably longer than acropodite (A), both quite complex and strongly armed; PfP broad, with four acute projections at its internal margin, two middle projections being more elongate, PfP ending in another elongated and acute apex directed laterobasally; A with internal margin bearing a process near middle, slightly broadened and acute, apex directed laterally, also wide and acute; solenomere (sl) simple and only slightly curved.

DISTRIBUTION. Brazil,Amazônas, São Paulo de Olivença, 3°27′23.2″S 68°48′01.3″W [ Attems, 1898, 1938; Schubart, 1946]. Attems [1938] erroneously placed that locality in Pará state.

Hoffman [in litt.] recorded this species from Padre Cocha and Rio Yanayacu , both near Iquitos, Peru. To prove the identity, he also depicted the left gonopod of a ♂ ( Fig. 8D, E ).
