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). 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).
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–b, 21h–i). 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–d, 24e, 24k).

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–b, 21h–i).
