Adult habitus. General color brown, patterned with yellow. Head with dark brown lappets and ocellar patch extending beyond M-line; central frons with a

pale quadrate spot; occiput dusky. Pronotum with wide median pale band; dark lateral bands irregular and bearing scattered pale rugosities ( Fig. 16 ). Wing membrane transparent, veins dark brown. Femora dark along dorsal margin and in narrow apical band; tibiae dark brown but paler on posterior margin.

Male. Forewing length 18 mm. Hammer thimble shaped, height greater than basal diameter ( Fig. 17 ). Adeagal apex short, triangular in outline with a small membranous nipple; ventrolateral margins very dark, membranous ventral lobes absent ( Fig. 18 ); hooks wide.

Etymology. The species name, used as a noun in apposition, honors the indigenous culture in this region of Colombia.

Diagnosis. This species will key to Anacroneuria quilla

Stark & Zúñiga in Stark et al. (1999) but the aedeagal apex is less hatchet-like in lateral aspect and the tip bears a small nipple-like projection rather than a notch. The aedeagus is also similar to that of A. canelo Stark but in that species the dorsal keel reaches the apex ( Stark 2001).

Ecological notes. The type locality is the same as that of A. pastora . This third-order stream is about 15-18 m wide and 0.40-0.70 m deep, with a mixed substrate composed of boulders, stones and patches of gravel and sands, primarily riffle zones and high slope. Natural riparian vegetation is present and the water quality is in optimum environmental condition; water temperature was 13-14°C and the air 16°C at the time of collection; these specimens were collected during the wet season.
