Distribution. This species was collected manually and by using pitfall traps in moss covered rocks in the mountain forests of the municipalities of Tota (2956–3200 m) and Villa de Leyva (2800 m), Boyacá Department, Colombia (Fig. 5).

Etymology. This species is named after the “altoandina” high mountain forest, where the types were collected.

Comments. Altavelia altoandina is the smallest known species of the genus. Although similar to A. columbiensis (Hungerford, 1930) in body coloration, the new species can be distinguished from the latter by the smaller size (4.62–5.62 mm), the lack of abundant golden setae on the head, pronotum and abdominal laterotergites (Figs. 1 A–B), the more elevated and sinuous male abdominal laterotergites (Fig. 1A), the dorsum of the male proctiger with a large central T-shaped projection and a pair of small anterolateral projections (Fig. 4A), and the strongly reflexed female abdominal laterotergites (Fig. 1B). Altavelia columbiensis is larger (about 7.70 mm) and has abundant golden setae on the head, pronotum and abdominal laterotergites (Figs. 6 C–D), less elevated and not sinuous male abdominal laterotergites (Fig. 6C), two central projections and no anterolateral projections on the dorsum of the male proctiger (Fig. 4C), and elevated, but not reflexed, female abdominal laterotergites.
