Types. Holotype: male from Reserva Natural Cerro Quininí  , Tibacuy, Cundinamarca, Colombia, 1740 m, 4.336805°N, 74.496111°W, 17–24.X.2015, Grupo Artropofauna Universidad Nacional de Colombia ( ICN –Ar 8266)GoogleMaps  . Paratypes: one female with same data as holotype ( ICN –Ar 8267). Two males from the same locality, 1887 m, 4.324833°N, 74.493305°W, 17–24.X.2015, Grupo Artropofauna Universidad Nacional de Colombia ( ICN –Ar 8270).GoogleMaps 

Etymology. The epithet is a noun in apposition that honors the Natural Reserve where the species was found, the Natural Reserve Cerro Quininí  , ancient territory of the Panches or Tolimas indigenous people of the Cariban language family, known by the Spanish invaders as fearsome warriors and cannibals, whose lives revolved around war.

Diagnosis. Males of A. quinini  sp. nov. can be easily distinguished from those of the remaining species of the genus by the presence of a bilobed RTA, with the ventral lobe long and finger-like, and the dorsal lobe serrated and wide ( Figs 8a –bView FIGURES 8, 21h –iView FIGURES 21). Females of A. quinini  sp. nov. are similar to those of A. guaitipan  sp. nov. by their general disposition of internal structures of the epigyne, but can be distinguished from those by their longer copulatory ducts, with the posterior epigynal border concave, and a semi-quadrangular epigynal pocket ( Figs 8c –dView FIGURES 8, 24e, 24kView FIGURES 24).

Description. Male (holotype). Total length: 2.39. Carapace lustrous black, 1.24 long, 0.91 wide, 0.72 high ( Fig. 17dView FIGURES 17). OC black lustrous, 0.63 long. Anterior eye row 0.96 wide and posterior 0.85 wide. Sternum black lustrous, 0.49 long, 0.38 wide. Labium black lustrous, 0.08 long, 0.13 wide. Chelicerae black with four retromarginal and two promarginal teeth. Palp brown with distal femur and patellae with long white hairs, with a bilobed RTA, with the ventral lobe long and finger-like, and the dorsal lobe serrated and wide, rounded tegular lobe (TL) and long embolic filament (EF) ( Figs 8a –bView FIGURES 8, 21h –iView FIGURES 21). Legs 4312, all black with I –II with metatarsi –tarsi yellowish, and III –IV yellow. Leg macrosetae: femur, I –II d 1 di; III d 2 di; IV v 1 di; patella, III –IV r 1 me; tibia, I v 2-2 -2; II v 2-1 -2, p 1 di; III –IV v 0-1-0, p 0-1-1, r 0-1-1; metatarsus, I v 2-2; II v 2-2, p 1 di; III v 1 -0-1, p 1-0-2, r 2 di; IV v 1 -0-1, p 1-0-1, r 1-0-2. Abdomen brown with cream-colored posterior marks and stripes ( Fig. 17dView FIGURES 17).

Variation (n= 3 males). Total length 2.01–2.39. Carapace length 1.11–1.27.

Female (paratype, ICN –Ar 8267). Total length 2.86. Carapace dark brown with a dorsal lighter mark, 1.31 long, 0.95 wide, 0.63 high ( Fig. 17eView FIGURES 17). OC black, 0.63 long. Anterior eye row 0.96 wide and posterior 0.87 wide. Sternum dark brown, 0.54 long, 0.46 wide. Labium dark brown, 0.11 long, 0.24 wide. Chelicerae dark brown, with five retromarginal and two promarginal teeth. Legs 4312, all yellow with lateral dark brown sides. Leg macrosetae: femur, I –II, IV d 1 di; III d 2 di; patella, III –IV r 1 me; tibiae, I v 2-2 -2; II v 1-2 -1, p 1 di; III v 1 me, p 1-1-0, r 1-1- 0; 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 1 -0-1, p 1-0-2, r 1-0-2; IV v 1 pr, p 1-0-2, r 1- 0-2. Abdomen dark brown with dorsal and lateral light brown marks and spots ( Fig. 17eView FIGURES 17). Epigyne ( Figs 8c –dView FIGURES 8, 24e, 24kView FIGURES 24) with anterior and medial copulatory openings, long copulatory ducts with the anterior portion concave in disposition, semi-concave posterior border and semi-quadrangular epigynal pocket, and oval anterior spermathecae.

Comments. The type material was collected in pitfall and Winkler traps in an Andean Oak ( Quercus humboldtii  ) forest ( Fig. 26cView FIGURES 26).
