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 –bView FIGURES 6, 20j –kView FIGURES 20). 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 –dView FIGURES 6, 24d, 24jView FIGURES 24).

Description. Male (holotype). Total length: 2.30. Carapace yellow with two posterior blackish marks, 1.23 long, 0.88 wide, 0.68 high ( Fig. 16hView FIGURES 16). 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.

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. 16hView FIGURES 16), 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. 16iView FIGURES 16). OC black, 0.67 long.

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. 16iView FIGURES 16). Epigyne ( Figs 6c –dView FIGURES 6, 24d, 24jView FIGURES 24) 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.
