Types. ɗ holotype (MCTP 17193) from Macapá, Amapá, Brazil, 24.–28.I.2004, R. A. Silva leg., 2 ɗ paratypes (MCTP 17033), also without abdomen, same location of the holotype.

Etymology. The specific name is an adjective and refers to the country of origin.

Diagnosis. This species can be distinguished from Trechalea and Paradossenus by the presence of a projection in the tegulum ( Figs 3 View FIGURES 1 – 5 , 14 View FIGURES 14 – 17 ) and a lateral protrusion of ventral division of median apophysis (LPV) ( Figs 3 View FIGURES 1 – 5 , 14 View FIGURES 14 – 17 ).

Description. ɗ (holotype). Carapace, 1.36 long, 1.24 wide, grayish, with two yellowish lateral bands, with brownish border, dorsum with brown dark spots and with three white lines near the fovea ( Fig. 1 View FIGURES 1 – 5 ). Chelicerae yellowish, faces brownish with vertical bands, almost glabrous medially with light setae on distal one­third of its length. Endites orange, 0.16 long, 0.09 wide; labium light brown, 0.18 long, 0.22 wide; sternum yellow, unmarked, 0.68 long, 0.65 wide. Legs yellowish, brownish dorsally. Abdomen missing. Clypeus 0.55 long, 0.03 high; dark at anterior margin. Anterior eye row moderately procurved, 0.40 wide; posterior recurved, 0.62 wide. Eye diameters, interdistances and ocular quadrangle: AME 0.09, ALE 0.06, PME 0.12, PLE 0.06; AME –AME 0.06, AME–ALE 0.03, PME–PME 0.09, PME–PLE 0.09, MOQ, 0.15 long, dorsal view, 0.19 frontal view, anterior width 0.09, posterior 0.23. Leg measurements: I femur 2.26/ patella­tibia 2.94/ metatarsus 2.23/ tarsus 1.11/ total 8.54; II 2.01/ 2.54/ 1.86/ 0.96/ 7.37; III 0.86/ 0.99/ 1.05/ 0.43/ 3.33; IV 1.02/ 1.05/ 1.11/ 0.40/ 3.58. Tarsal claws with elongated teeth ( Fig. 16 View FIGURES 14 – 17 ). Bothrium of trichobothria with distinct hood ( Fig. 17 View FIGURES 14 – 17 ). Palpus ( Figs 2–5 View FIGURES 1 – 5 , 14 View FIGURES 14 – 17 ) presenting a ventral protrusion pointing retrolaterally ( Fig. 3 View FIGURES 1 – 5 ) and three large spines, two positioned laterally in dorsal view and one dorsal. The retrolateral tibial apophysis presents only one branch (ectal division) with the distal portion curved ( Figs 3–5 View FIGURES 1 – 5 , 15 View FIGURES 14 – 17 ). Ventrodistal protuberance of palpal tibia prominent, retrolaterally projected ( Fig. 3 View FIGURES 1 – 5 ).
