Bottom Line: We describe and illustrate Bumbalennoni, a new theraphosid species from Caxiuanã, Pará, Brazil.Females additionally differ in the spermathecal morphology.As a consequence of the name replacement, three new combinations are established.

ABSTRACT
We propose the name Bumba as a new name for Maraca, preoccupied by Maraca Hebard, 1926 (Orthoptera). We describe and illustrate Bumbalennoni, a new theraphosid species from Caxiuanã, Pará, Brazil. This species differs from the other species of the genus in the extremely reduced keel on male palpal organ and in the higher number of labial and maxillary cuspules. Females additionally differ in the spermathecal morphology. As a consequence of the name replacement, three new combinations are established.

Bumbalennoni sp. n.: 1–4 and 6–8 male holotype (MPEG 983) 5, 9 female paratype (MPEG 19039). 1–2 Tibiae and metatarsi of left leg I: 1 Prolateral 2 Ventral 3–4 Copulatory bulb: 3 Prolateral 4 Retrolateral 5 Spermathecae, dorsal 6 carapace, dorsal 7 abdomen, dorsal 8 retrolateral process in male palpal tibiae 9 sternum, ventral Scales: 1–2: 3 mm; and 3–5: 1 mm.

Fovea transverse, straight, width 2.06. Labium length 1.90, width 2.80, with 58 cuspules, maxillae with 218 cuspules in a triangular group with base on the proximal edge. Sternum length 7.75, width 6.63, posterior sigillae submarginal. Chelicerae with 12/11 promarginal teeth (5 to 8/9 from distal tip, smaller); a group 29/30 very small proximal teeth, behind promarginal ones. Tarsi I–IV densely scopulate, scopula I–III entire, IV divided by a narrow line of longer conical setae. Metatarsi I scopulate on distal half, II scopulate on distal third, III scopulate on distal fourth and IV apically scopulate. Tibia I with two prolatero-ventral, distal, unequal apophysis (Figs 1–2). Flexion of metatarsus I between both branches of the tibial apophysis. Palpal organ piriform (Figs 10–11), in Fig. 11 TA detailed; with distal ring-shaped keel (Fig. 12), perpendicular to major axis (Figs 3–4). Palpal tibia with a setose retrolateral process (Fig. 8); setae thick. Length of leg and palpal segments, in Table 1. Spination: Femora I, 3P; II, 3P, 1R; III, 4P, 3R; IV, 2P, 2R; palp, 1P.

Color: Cephalothorax (Fig. 6) and legs reddish brown, abdomen light brown with central patch of urticating setae darker (Fig. 7). Type III (Fig. 13) and type IV urticating hairs present. PMS well developed, PLS normal, apical segment digitiform.
