Tamaris, R. Turrizo (MEUV). Paratypes: COLOMBIA: 3&amp;male;, same data, except 5 June 2004 (MEUV). 4&amp;male;, same data, except 8 July 2004 (BPS, BYU, MEUA, MHN-ICN). 1&amp;male;, same data, except 12 January 2004 (MEUV). 1&amp;male;, same data, except 7 June 2004 (MEUV). 1&amp;male; same data, except 2 July 2004 (MEUV). 1&amp;male;, same data, except January 2005, C. Tamaris, D. Serna (BPS). <b>Adult habitus.</b> Teneral color mostly pale yellow brown patterned with brown. Head yellow with pale dusky areas on central frons, and darker lappets (Fig. 27). Pronotum pale with narrow midlateral dark bands. Wing transparent, veins pale brown or amber. Legs pale except femora with narrow dark, apical band, and tibiae dark on outer proximal and distal edge. <b>Male.</b> Forewing length 16.5–18.0 mm. Hammer thimble shaped, height subequal to basal diameter (Fig. 28). Projecting aedeagal apex about as long as wide, membranous lobes absent; shoulders bulging in ventral and dorsal aspect (Figs. 29, 31) and projecting slightly as ear-like lobes in lateral aspect (Fig. 30). <b>Female.</b> Unknown. <b>Larva.</b> Unknown. <b>Etymology.</b> The species name, used as a noun in apposition, honors the native people who live in the Sierra Nevada de Santa Marta. <b>Diagnosis.</b> The aedeagus of this species is generally similar to that of <i>A. marta</i> Zúñiga &amp; Stark, a species also known from lower elevations of Sierra Nevada de Santa Marta. In <i>A. tayrona</i> the apical lobe is slightly notched and projects beyond the shoulders somewhat more than in <i>A. marta.</i> <b>Ecological notes.</b> The type locality is in the Región Natural Caribe of Colombia on the northwest side of Nacional Natural Park Sierra Nevada de Santa Marta. The Holdridge life zone system classification is very humid subtropical forest (Espinal &amp; Montenegro 1963), with 2446 mm mean annual rainfall and a monomodal pluviometric regime; the wet period is from April to November and the dry period from December to March. The Gaira River is a third-order stream, about 6 m wide and 0.25-0.50 m depth, with a substrate composed of boulders, stones, patches of gravel and sands, riffle and pool zones. The variation of water volume is from 118 l/s to 482 l/s and current speed is from 0.49-0.77 m /s, in relation to dry or wet season. The water is fresh, oligotrophic, in good ecological condition, without evident pollution (18°C, 6.9 mg /l O 2,12.5 µS/cm, pH 6.7). The natural riparian vegetation is abundant and consists mainly of <i>Calatola costarisensens</i>, <i>Tovomita weddeliana</i>, <i>Rondeleti</i> sp. <i>Croton bogotanus</i>, <i>Pouteria argaucoencium</i> and <i>Clusia multiflora</i> (Tamariz-Turizo et al. 2007).
