Figs 10a–d, 17h–i, 22a–b, 25a, 25g, 26d, 27
Types. Holotype: male from Pozo Azul, Vereda La Vanguardia, Villavicencio, Meta, Colombia, 375 m [4.164320°N, 73.625789W], 16.IV.2005, unknown coll. (ICN –Ar 6558). Paratype: one female from Villa Lole, Vereda Apiay, Villavicencio, Meta, Colombia, 453 m [4.084531°N, 73.566513°W], E. Flórez & Estudiantes de Aracnología Universidad Nacional de Colombia (ICN –Ar 7185).
Etymology. The epithet is a noun in apposition that honors the Sikuani, or Guahibo, indigenous people of the Guajiboan language family, which inhabits the region of the type locality.
Diagnosis. Males of A. sikuani sp. nov. are similar to those of A. guaitipan sp. nov. and A. tanimuca sp. nov. by the shape of the RTA. However, they can be recognized from those by the presence of a single bifurcated RTA, with the ventral and the dorsal lobes with the same proportion and shape (Figs 10a–b, 22a–b). Females of A. sikuani sp. nov. are similar to those of A. bochica sp. nov. and A. chie sp. nov. by their general disposition of internal structures of the epigyne, but can be distinguished from those by their longer copulatory ducts (cd), the presence of a single and medial pocket (po) on the posteriorly extended epigynal plate, and a posterior slender spermathecae (Figs 10c–d, 25a, 25g).
Description. Male (holotype). Total length: 2.43. Carapace yellow, 1.45 long, 1.01 wide, 0.78 high (Fig. 17h). OC black, 0.61 long. Anterior eye row 1.14 wide and posterior 0.91 wide. Sternum yellow, 0.54 long, 0.44 wide. Labium yellow, 0.10 long, 0.20 wide. Chelicerae yellow with black proximal side, with three retromarginal and two promarginal teeth. Palp brown with distal femur and patella with long white hairs, long embolic lamella (EL), and a bifurcated RTA, with its ventral and dorsal lobes with the same shape (Figs 10a–b, 22a–b). Legs 1342, I dark brown, II–IV yellow. Leg macrosetae: femur, I–II, IV d 1 di; III d 2 di; patella, III–IV r 1 me; tibia, I v 2-2 -2; II v 1- 2 -2, p 1 di; III–IV v 1 pr, p 1-0-1, r 1-0-1; metatarsus, I v 2-2; II v 2-2, p 1 di; III v 2 -0-1, p 1-0-2, r 1-0-2; IV v 1 -0- 1, p 1-0-2, r 1-0-2. Abdomen white with an uneven dark brown pattern of marks (Fig. 17h).
Female (paratype). Total length 2.50. Carapace yellow with some posterior black marks, 1.26 long, 0.91 wide, 0.60 high (Fig. 17i). OC black, 0.47 long. Anterior eye row 0.86 wide and posterior 0.78 wide. Sternum yellow, 0.48 long, 0.40 wide. Labium yellow, 0.15 long, 0.18 wide. Chelicerae yellow, with five tiny retromarginal teeth, and one promarginal tooth. Legs 4312, all yellow. Leg macrosetae: femur, II–III d 1 di; patellae, III–IV r 1 me; tibiae, I v 2-2 -2; II v 1-2 -2, p 1 di; III–IV v 1 me, p 1-1, r 1-1; metatarsus, I v 2-2; II v 2-2, p 1 di; III v 2-1, p 1- 0-2, r 1-0-2; IV v 1 pr, p 1-0-2, r 1-0-2. Abdomen gray, with a dark brown reticulated pattern of marks (Fig. 17i). Epigyne (Figs 10c–d, 25a, 25g), with anterior copulatory openings, short copulatory ducts and posterior slender spermathecae, with a rounded pocket in a posteriorly extended epigynal plate.
Comments. The holotype male was collected in a yellow tray trap, and the female paratype was collected manually in a rotten trunk in the soil, in a secondary lowland semi wet forest (Fig. 26d).
Distribution. Colombia (Meta) (Fig. 27). Known altitudinal distribution: 375– 453 m.
