description: <i>Anacroneuria vagante</i> sp. n. (Figs. 6-10) <b>Material examined.</b> Holotype &amp;male;, <b>BOLIVIA: La Paz Department</b>, Province Nor Yungas, Rio Vagante, Vagante, 16 <b>°</b> 11’ S, 67 <b>°</b> 41’ W, 3650’, 12 November 2009, S.M. Clark, H.R. Hinkson (USNM). <b>Adult habitus.</b> General color brown, patterned with areas of dark brown and pale brown or yellow. Head with a large area of dark pigment covering ocellar region and extending forward and laterad over much of frons (Fig. 6); lappets dark brown and occiput with area of dark pigment outlining a pair of triangles with pale centers; antennae and palpi brown. Mid and fore femora banded with dark pigment in apical third, tibiae uniformly dark brown (hind legs missing). Wings membranes brown, veins dark brown. <b>Male.</b> Forewing length 8.5 mm. Hammer thimble shaped (Fig. 7). Aedeagal apex simple, scoop shaped (Figs. 8-10), but with heavily sclerotized lateral margins, a prominent dorsal keel which forms an Xpattern (Fig. 10), and a pair of prominent membranous ventral lobes; lateral margins in dorsal aspect somewhat scalloped. Hooks slightly wider than in most species. <b>Female.</b> Unknown. <b>Larva.</b> Unknown. <b>Etymology.</b> The species name, used as a noun in apposition, is based on the type locality of Rio Vagante. <b>Diagnosis.</b> The aedeagus of <i>A. vagante</i> is most similar to that of <i>A. karina</i> Stark, known from Venezuela (Stark 1999), however that species lacks the distinctive head and pronotal pattern of <i>A. vagante</i>; in addition the bases of the aedeagal hooks in <i>A. karina</i> are more swollen, the dorsal keel is shorter, and the ventral membranous lobes smaller in that species than in <i>A. vagante.</i> The aedeagus of the new species is also generally similar to that of <i>A. manauensis</i> Ribeiro-Ferreira, described from Brazil (Ribeiro-Ferreira &amp; Froehlich 2001), <i>A. puna</i> Stark, described from Ecuador (Stark 2001), and <i>A. taylori</i> Stark, described from Bolivia (Stark 2004). The new species differs from the latter two in having a much broader area of dark pigment on the frons, but also differs from the former two species in having a prominent pair of membranous lobes on the aedeagal apex. It differs from the latter species in lacking subchelate aedeagal hooks and in having larger membranous lobes on the aedeagal apex. <i>Anacroneuria vagante</i> sp. n. La Paz
