Dorsum of male proctiger with two elongated, narrow projections (Fig. 4E). Paramere elongated, flat, slightly curved mesally, with curved apex slightly flattened, with a row of setae on base of ventral surface (Fig. 4K).

Apterous female (Fig. 2B). Measurements (paratypes; n = 2): BL 7.68–7.90, HL 0.73–0.76, HW 0.73–0.76, ANT I 1.08–1.30, ANT II 0.89–1.30, ANT III 0.83–0.99, ANT IV 0.95–1.02, EYE 0.33–0.36, PL 1.68–1.73, PW 1.69–1.73; FORELEG: FEM 1.88–1.91, TIB 1.88–1.90, TAR I 0.06–0.09, TAR II 0.32–0.35, TAR III 0.44–0.48; MIDLEG: FEM 2.20–2.50, TIB 2.40–2.60, TAR I 0.13–0.16.

Color as in apterous male. Body structure similar to male, except abdominal laterotergites more elevated, sinuous, reflected over posterior abdominal segments; last laterotergite produced into long, thick spines (as long as mediotergite VII) (Fig. 2B).

Type material examined. All specimens apterous. HOLOTYPE ♂ (IAVH E-175688): ‘ Colombia, Norte de Santander \ PNN Tama, Sector Orocué \ Bosque alto andino secundario, 7.25 N 72.26 W \ 2750 m, Interceptación de vuelo \ 28.vi.1999 \ E. González & D. Dávila’ . 1♀ PARATYPE (IAVH E-175661), 1♂, 1♀ PARATYPES (UPTC MHN-ART-0077, MHN-ART-0078): same data as holotype .

Distribution. This species is known from Parque Nacional Natural Tama (2750 m), a high mountain forest area of Norte de Santander Department, Colombia (Fig. 5).

Etymology. The species’ name “ montana ” comes from the Spanish word “montaña” (= mountain).

Comments. Altavelia montana is similar to A. daza in body color, but can be distinguished from it by the smaller size (6.60–7.90 mm), the dorsum of the male proctiger with two elongated, narrow projections (Fig. 4E), the shape of parameres (compare Figs. 4K and Fig. 4I), and the long, thick posterior spines on the female last abdominal laterotergite (Fig. 2B). Altavelia daza is 9.20–9.80 mm long, has larger posterolateral projections on the dorsum of the male proctiger, and much shorter and narrower spines on the last female abdominal laterotergite.
