Ključne besede; Plecoptera, Periidae, Anacroneuria, Peni, Bolivija, [aksonomija Sixteen /liirtt^ujitffncj species have been described bas£d partiaJly or entirely on Penjvi;in and Bolivian specimens (Enperj,e]n 1909. NavXs 1915, 1927, Kij\pAlek 1921, 1922, Jewett J959). Unfortunately only two o/ those, h. balivknsis (Enderleik) ajid A. vaiiegata Klapalhk were described in sufficient detail to permit recognition (ZwiCK 1973) but Peruvian specimens of Ihe latter Species, subsequently redeicribed from a Colombian lectotype ant! placed as a synonym of .\chmidii (Ekderlew) by ZwiCK (1973), have not been located, Tewf.tt (1959) also reported the occurreitec ofpeMke (ENDEtiLEiK), A. schmidri (Enderljiin) and A. oficimian^ fEN'DERLErv} in Peru birt these are misidentifications, [n this study 11 of the reniaining species are redescribed from types and 28 species new to .science are proposed prtm^irily from spec i meni in the National Museum of Natural History. Washington, DC CUSNM). Addiiional specimens were provided by the California Academy of Scicnets, San Francisco, CA (CAS), the Carnegie Museum of Natural History.

Type specimens for tlie Toll owing species have not been located during this 5tudy, Consequently we are unable to apply these names to Anacmiieuriü populations; Annciioijeuiia comiccina (NavA5, 1927), type locality probably Coroico, Bolivia rather than Sutchan.

Nymph. Unknown. Etymology The species name, used as a noun in apposition, honors the Chipaya people of Bolivia, Diagnosis, The aedeagus of/l. chipaya is most similar to chat of A naica but is less robust and more strongly nmrowed at the apex. In addition, the hooks of A, nazca are more massive and more Strongly keeled. These species are also similar to A. pacaje but that species has a long U-shaped dorsal keel and the aedeagal apex is distinctly wider than the subapical neck. Atiacroiieuria cosiiipata, spec. nov.

Z wick (1973) designated a Itctotype and placed this species as a synonym of A. alignsticollii (ENCERLF.trt. A)though the aedeagus is similar, Ihcse species are distinct. The aedeagal apex of angiisncoUis bas almost parallel sides to the tip, a distinct dorsal keel, digitate aedeagal hook apices, no membranous ventral lobes, and a long apex beyond the hooks. In A. hsvtdlirichi the aedeagal apex is convergent (o the tip, there is no dorsal keel, the aedeagal hooks arc not digitate, a p:tir of ventnoapical membranous knobs are present and the area beyond the hooks is relatively short. This species appears to be one of the more common stoneflies of southern Peru and northern Bolivia.

Aedeagal apen simple, mesal projection short; ventral membranous lobes absent, dorsal keel absent, hooks slender (Figs. 145-147). Female. Unknown. Nymph. Unknown. Etymology. The species name, used as a noun in apposition, honors the Utu people of the Peruvian-Bolivian border region. Diagnosis. This species is similar to A. cboneTa and A. muesca (Stark 1995) but differs in apical aedeagal features. In ventral aspect, A. wu lacks the low subapical mounds found in .4 chonera and also lacks the notched apex found in A. muesca. Anacreneuriü vilc' '1 ■■■ 15 I',' T -Vv' - -3 ' !'
