Figs 5, 6View FIGURES 5, 6; Map 1

Type material. ♂ holotype from IPAM, Fazenda Arataú , Novo Repartimento [04°14'52.22'', 49°57'01.35''W], Pará, Brazil, 11-12.VIII.2003 ( MPEG 34848View Materials)  . ♂ paratype, same data, 17-18.VI.2002 ( MPEG 34849View Materials)  .

Etymology. The specific name refers to a folk music style, typical from state of Pará, the "Carimbó".

Diagnosis. Males of A. carimbo  n. sp. are similar to those of A. blakei Bonaldo & Brescovit  and A. carranca Bonaldo & Brescovit  by the large dorsal lobe of the RTA, and by the median extension of the median apophysis comprising two pieces, the proximal one sculptured ( Bonaldo & Brescovit 2005: figs 11, 12, 14, 15). They differ from those of A. carranca  by the finger-shaped, not excavated cymbial retro-dorsal process, and from those of A. blakei  by the shorter apical extension of RTA’s dorsal lobe, which is devoid of a ventral prong ( Figs 5, 6View FIGURES 5, 6).

Description. Male (holotype, MPEG 34848). Carapace pale yellow, cephalic region slightly darker, anterior median eye area with black spot divided by longitudinal gap; chelicerae pale yellow with fangs brown; endites and labium pale yellow, with white apex; sternum pale yellow with pale brown margins; legs yellow; abdomen pale yellow. Total length 3.80. Carapace 1.80 long, 1.45 wide, 0.41 high. Clypeus 0.14 high. Eye diameters and interdistances: AME 0.11, ALE 0.08, PME 0.10, PLE 0.08; AME –AME 0.08, AME –ALE contiguous, PME –PME 0.15, PME –PLE 0.05, ALE –PLE contiguous. MOQ length: 0.24, front width: 0.28, back width: 0.27. Chelicerae 0.65 long, with 3 promarginal and 2 retromarginal teeth. Sternum 0.96 long, 0.98 wide. Abdomen 1.83 long, 1.40 wide. Leg measurements: I: femur 1.66/ patella 0.64/ tibia 1.51/ metatarsus 1.44/ tarsus 1.10/ total 6.35. II: 1.60/ 0.61/ 1.38/ 1.46/ 1.08/ 6.13. III: 1.46/ 0.59/ 1.32/ 1.50/ 1.14/ 6.01. IV: 1.66/ 0.60/ 1.61/ 1.81/ 1.26/ 6.94. Leg spination: I: femur d1-1-0, p0-0-1, r0, v0; tibia d0, p0, r0, v3-2 -2; metatarsus d0, p0, r0, v2-2 -0. II: femur d1-1-0, p0, r0, v0; tibia d0, p0, r0, v2-2 -2; metatarsus d0, p0, r0, v2 -r1-0. III: femur d1-1-0, p0, r0, v0; tibia d0, p0, r0, v0; metatarsus d0, p0, r0, v0. IV: femur d1-1-0, p0, r0, v0; tibia d0, p0, r0, v0; metatarsus d0, p0, r0, v0. Palp: RTA with two lobes, ventral lobe small; apical spur large, with base arising proximally from ventral lobe, dorsal lobe large, sub-rectangular, oriented dorso-apically, with small apical process; cymbial prolateral process large, separated from cymbial transversal process; cymbial transversal process long, slender, without basal prong; cymbial retrolateral tubercle a wide transversal protrusion; cymbial retrodorsal process finger-shaped, conical; both prolateral tegular keel and ventral tegular keel present, small, sub-contiguous; tegular retrolateral groove present, wide; distal extension of median apophysis blunt, slightly protruded apically; median extension of median apophysis composed of two pieces, proximal one sculptured; proximal extension of median apophysis long ( Figs 5, 6View FIGURES 5, 6).
