Types. Holotype: male from Siachoque , Boyacá, Colombia, 3220 m, 5.451666°N, 73.17°W, 12.XI.2014, J. Barrera, S. Mondragón ( ICN –Ar 8259) . Paratypes: two females from Toca , Boyacá, Colombia, 3500 m, 5.548333°N, 73.108611°W, 27.XI.2014, J. Barrera, S. Mondragón ( ICN –Ar 8260–8261). One female from Pesca , Boyacá, Colombia, 3180 m, 5.454722°N, 73.119166°W, 10.XII.2014, J. Barrera, S. Mondragón ( ICN –Ar 8262).

Etymology. The epithet comes from Spanish (“ma” = “mom”), in honor of Esperanza Jiménez Suárez, good friend and author’s mother, for her friendship, guidance, help, and continued support during the author’s studies and research on Neotropical and Colombian salticids, and main financial supporter of the author’s long collecting trips, including some of this research.

Diagnosis. Males of A. mae sp. nov. are similar to those of A. quimbaya sp. nov. and A. sua sp. nov. by the shape of their RTA, but can be distinguished from those by their combined presence of a dorsal scutum in the male abdomen, the absence of an embolic lamella (EL) and the presence of an embolar disc spur (EDS) ( Figs 6a–b , 20j–k ). Females of A. mae sp. nov. are similar to those of A. sie sp. nov., A. somondoco sp. nov. and A. sua sp. nov. by their general disposition of internal structures of the epigyne, but can be distinguished from those by their longer copulatory ducts, with slender spermathecae ( Figs 6c–d , 24d, 24j ).

Description. Male (holotype). Total length: 2.30. Carapace yellow with two posterior blackish marks, 1.23 long, 0.88 wide, 0.68 high ( Fig. 16h ). OC black, 0.57 long. Anterior eye row 0.93 wide and posterior 0.84 wide. Sternum yellow, 0.48 long, 0.38 wide. Labium yellow, 0.10 long, 0.17 wide. Chelicerae brownish yellow with four retromarginal and one promarginal tooth. Palp yellow with distal femur and patellae covered by long white hairs, a wide RTA with a longer ventral lobe, and a rounded proximal tegular lobe (TL) ( Figs 6a–b , 20j–k ). Legs 4312, all yellow. Leg macrosetae: femur, I–II d 1 di; III d 2 di, p 1 di; IV d 2 di; patellae, III–IV r 1 me; tibia, I v 2-2 -2; II v 1-2 -2, p 1 di; III–IV v 1 -0-1, p 1-1, r 1-1; metatarsus, I v 2-2; II v 2-2, p 1 di; III–IV v 1 -0-1, p 1-0-2, r 1-0-2.

Abdomen yellowish with a dorsal scutum ( Fig. 16h ), with a group or rigid and long hairs ventrally and posteriorly in the abdomen.

Female (paratype, ICN–Ar 8260). Total length 3.61. Carapace brown, 1.50 long, 1.07 wide, 0.77 high ( Fig. 16i ). OC black, 0.67 long. Anterior eye row 1.13 wide and posterior 0.99 wide. Sternum brown, 0.66 long, 0.53 wide. Labium brown, 0.20 long, 0.24 wide. Chelicerae brown, with four retromarginal and one promarginal tooth.

Legs 4312, all yellowish brown. Leg macrosetae: femur, I–II, IV d 1 di; III d 2 di; patellae, III–IV r 1 me; tibiae, I v 2-2 -2; II v 2-2 -2, p 1 di; III–IV v 1 pr, p 1-1, r 1-1; 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 1-1-2. Abdomen brown with a reticulated gray pattern of coloration ( Fig. 16i ). Epigyne ( Figs 6c–d , 24d, 24j ) with anterior and medial copulatory openings, convex disposition of the anterior copulatory ducts, copulatory ducts long, a posterior single medial pocket, and medial and slender spermathecae, with a long anterior lobe after the fertilization ducts.

Variation (n= 3 females). Total length 3.61–4.18. Carapace length 1.50–2.06.

Comments. The type material was collected in pitfall traps in intervened Andean Ecosystems, as Páramo and high-Andean wet forests.

Distribution. Colombia (Boyacá) ( Fig. 27 ). Known altitudinal distribution: 3180–3500 m.
