description: <i>Neonemura copa</i> sp. n. (Figs. 1-4) <b>Material examined.</b> Holotype &amp;male; from <b>CHILE:</b> Provincia Aisén, Municipalidad Cisnes, Area Protegida Lago Copa: S side E Lago Copa, springbrook at Cliffs Preserve, 44.89227 <b>°</b> S, 72.62291 <b>°</b> W, elevation 25-35 m, 8-9 December 2009, ultraviolet trap, H 2 O 6 <b>°</b> C, J. Morse, G. Vazquez, N. Gonzalez (NMNH). <b>Adult habitus.</b> General color brown with scattered pale areas. Head dark brown over most of surface, but with a pair of parenthesis-shaped pale spots anterolateral to posterior ocelli, and with three additional pale spots on anterior region of frons (Fig. 1); pronotum brown with pale median band and lateral margins. Femora banded, hind femora each with dark basal and apical bands, fore- and midfemora each without basal band; all tibiae dark at knee, hind tibiae also with apical dark band. Wing membrane pale brown, veins brown. <b>Male.</b> Macropterous. Forewing length 6.5 mm. Tergum 10 divided into a pair of lateral sclerites and a median posterior one; median sclerite covered over much of surface with small spines (Fig. 2). Epiproct a slender, curved, hook-like process, thick basally and barely visible in dorsal aspect at the base of median sclerite. Cerci each bearing a low dorsal ridge in apical third and a pale membranous area anterior to ridge; cerci not markedly bilobed in lateral aspect (Fig. 4). Sternum 9 prolonged into an upwardly curved subgenital plate, bifid at tip in dorsal or caudal aspect (Figs. 2-4); margins of plate broad in basal third, then significantly narrowed, but width variable to apex (Fig. 3). Paraprocts mostly membranous but bearing slender sclerite extending almost to apex; tips of paraprocts not exceeding apex of sternum 9. Vesicle relatively long and slender, club-shaped and narrowly attached to base of subgenital plate (Fig. 3). <b>Female.</b> Unknown. <b>Larva.</b> Unknown. <b>Etymology.</b> The species name is based on the type locality, a small springbrook entering Lago Copa, and is used as a noun in apposition. <b>Diagnosis.</b> <i>Neonemura</i> currently includes only three species (Froehlich 2010), all known from Chile or Chile and Argentina. <i>Neonemura copa</i> lacks the spiny dorsal patches found on the bases of the paraprocts of <i>N. illiesi</i> Zwick (Zwick 1972), and it is a much paler species than <i>N. maculata</i> Vera (Vera 2008a), however it is similar to the widely distributed species, <i>N. barrosi</i> (Navás) (Aubert 1960; Stark et al. 2009). Males of these two species have similarly shaped subgenital plates in ventral aspect but the paraprocts exceed the subgenital plate apex in <i>N. barrosi</i> and the cerci are strongly bilobed in lateral aspect in that species. <b>Habitat.</b> The type locality is a shallow, first order rheocrene springbrook providing water for the Cliffs Preserve Lodge beside Lago Copa. The light trap was located over the springbrook about 70 m west of the lodge, about 30 m from the edge of the lake and about 10-20 m below the spring head. Water temperature at the time of collection was 6 <b>°</b> C. The forest surrounding the Cliffs Preserve Lodge consists of <i>Bosque siempreverde laurifolio</i> (Evergreen Laurel-leaf Temperate Rainforest). The forest is original growth and consists of a canopy overwhelmingly dominated by <i>Laureliopsis philipiana</i> (Looser) R. Schodde, and <i>Weinmannia trichosperma</i> Ruiz &amp; Pav. Smaller numbers of <i>Nothofagus betuloides</i> (Mirb.) Blume and <i>N. nitida</i> Ann. K.K. Hofmus are found in areas immediately adjacent to the lake, or directly adjacent to its larger tributary rivers where disturbance is frequent (P. McMillan, personal communication).
