description: <i>Anacroneuria tucuman</i> sp. nov. (Figs. 5-9) <b>Material examined.</b> Holotype &amp;male; and 1&amp;male; paratype from Argentina, Tucuman Province, Horco Molle, 700 m, 15 January 1980, L. Stange (FSCA). <b>Adult habitus.</b> General color pale yellow brown. Head with brown lappets and a diffuse spot forward of ocelli and a pair of small diffuse spots between lappets. Pronotum mostly brown but with pale lateral margins, a pale median band on the anterior half of the disk and a pale area incorporated within dark region in center of disk (Fig. 5). Legs pale brown except for narrow dark brown band on distal end of femora. Wings pale, transparent; veins pale amber except for C and R veins which are very pale. <b>Male.</b> Forewing length 12-14 mm. Hammer a low, almost transparent bubble-like structure (Fig. 6). Aedeagal apex simple, but slightly offset from shoulders by a subtle notch (Figs. 7-9); a pair of small membranous lobes occur on the posterior margins of the apical area and an inverted Y-shaped keel with long stalk occurs on the dorsum. In lateral aspect the sclerotized area bulges slightly and is offset from the pale keel. Hooks slender (Figs. 7, 9). <b>Female.</b> Unknown. <b>Larva.</b> Unknown. <b>Etymology.</b> The species name, used as a noun in apposition, is based on the Argentine province in which the type specimens were collected. <b>Diagnosis.</b> Only three <i>Anacroneuria</i> species are currently known from the neighboring province of Salta [<i>A. arrazayalensis</i> Orce (Orce 2003); <i>A. marshalli</i> Stark (Stark 2007); <i>A. saltensis</i> Froehlich (Froehlich 2002)] and only <i>A. reedi</i> (Navás) (Navás 1919), a species whose identity is in question (Illies 1966), has been reported from Tucuman Province. The aedeagus of the new species is generally similar to that of <i>A. saltensis</i> but the keel in that species consists of a pair of parallel lines, the apex is not offset from the shoulders and the hammer is thimble shaped. Several other Andean species, such as <i>A. pachacuti</i> Stark &amp; Sivec, 1998 have similar aedeagal shape and features but none have the combination of a slightly offset apex, a Y-shaped keel and the low bubble-like hammer found in <i>A. tucuman.</i> <i>A. tucuman</i> sp. nov.
