Adult habitus. General color dark brown, patterned with yellow. Head with dark brown ocellar spot expanded anterolaterally along M-line; lappets dark brown ( Fig. 21 View Figs ). Pronotum dark brown laterally and pale along median suture. Wings with a slight brown tint, veins dark brown with Sc, R and M very dark, C and costal crossveins paler. Legs banded, femora pale basally and dark brown apically, tibiae with yellow mesal and dark brown basal and apical bands.

Male. Forewing length 11.5 mm. Hammer thimble shaped, height greater than basal diameter. Aedeagal apex short, scoop shaped in lateral aspect ( Fig. 25 View Figs ) and bearing obscure membranous ventral lobes; slender apical area widest at mid length and offset from shoulders by slight basal constriction accented with dark sclerotization ( Fig. 24 View Figs ). Aedeagal hooks chelate, dorsal keel composed of two close-set, fragmented ridges ( Fig. 26 View Figs ).

Female. Forewing length 15 mm. Subgenital plate with four subequal lobes, median notch larger than lateral notches. Setal patch of sternum 9 sparse mesally in stem region and denser posterolaterally ( Fig. 22 View Figs ).

Egg. Spindle shaped with small button collar and smooth chorion ( Fig. 23 View Figs ).

Larva. Unknown.

Etymology. The species name, used as a noun in apposition, refers to the mountain range at the area of the type locality.

Diagnosis. This species is a member of the Anacroneuria aymara   species group ( Stark & Sivec 1998; Zúñiga & Stark 2002). The aedeagus is most similar to that of A. farallonensis Rojas & Baena   but the apex is not expanded as in that species and the fragmented bead-like aspect of the keel lines is distinctive.

Ecological notes. The type locality is in the Cordillera Occidental and is part of Región Natural Andina of Colombia on the low part of “ Macizo de Tatamá ”. This second-order stream is about 5-8 m wide and   0.30-0.60 m deep, with a mixed substrate composed of boulders, stones, patches of gravel and sands, in riffle zones with high slope. Water temperature was 15°C and the air 18°C at the time of collection. Natural riparian vegetation is present and the water quality is in optimum environmental condition. The specimen was collected at the start of dry season.
