New species and records of Anacroneuria (Klapälek) from Venezuela (Insecta, Plecoptera, Perlidae) By Bill P. Stark Stark, B. P. (1995): New species and records of Anacroneuria (Klapälek) from Vene-zuela (Insecta, Plecoptera, Perlidae). -Spixiana 18/3: 211-249 A minimum of 31 species of the genus Anacroneuria (Klapälek) are recorded from Venezuela, including 18 described as new species. Eight species are described from Cerro de la Neblina and other remote sites in Territorio Federal Amazonas, 6 are described from Cordillera de Merida or Sierra de Perija, 3 are described from the Maracay area, and one is described from a site in the State of Bolivar. A. bifasciata (Pictet) and A. fenestrata (Pictet) are redescribed and notes are given for A. intermixta (Walker) and A. signata (Walker). Nine additional species represented by unassociated females are described under informal designations. A few unassociated and associated nymphs are also described. Dr. Bill P. Stark, Mississippi College, Dept. of Biological Sciences, Box 4045, Clinton, Mississippi, 39058, USA. Introduction Anacroneuria is a widespread and diverse neotropical stonefly genus with over 130 nominal but poorly known species. 23 species have been described from the northern Andes of Colombia and Venezuela but types are available for only 15 of these and most are known from Single type specimens (Stark unpublished, Benedetto unpublished). Two species, A. intermixta (Walker) and A. signata (Walk-er), both known from female types, were described from Venezuela, otherwise the "known" Anacrone-uria fauna of Venezuela consists of A. bifasciata (Pictet) (Zwick 1972, 1973), A. schmidti (Enderlein) (Jewett 1959), and A. iridescens Klapälek (Klapälek 1922). The latter two species records should not be considered valid until the specimens can be located and reexamined. Presently, no Anacroneuria have been identified from the isolated table top mountains along the Venezuelan-Brazilian border. This study is based largely on 1984-1985 collections made on the expe-dition to the Cerro de la Neblina National Park, under the direction of the Fundacion para el Desarrollo de las Ciencias Fisicas, Mathematicas y Naturales of Venezuela, and the Smithsonian Institution. Collections from this locality have already produced a number of previously undescribed species in several insect Orders, including four species in the relatively rare stonefly genera, Enderleina and Macrogynoplax (Stark 1989, Stark & Zwick 1989). Specimens from other Venezuelan localities were obtained from the Smithsonian or from the Departmento de Zoologia Agricola, U.C.V., Maracay, Venezuela, through O. S. Flint, Jr. of the Smith-sonian. The Venezuelan samples were carefully compared with a large series of Anacroneuria from Bolivia, Colombia, Costa Rica, and localities throughout the Neotropics. Study of this material suggests minimal overlap of Venezuelan species with those known from Colombia, and no overlap with Costa Rica and other Neotropical regions. A recently described species from Colombia (Rojas and Baena 1993) does not appear to be closely related to any of the species included in this study. The Venezuelan material represents 31 species including 18 which are described as new. Holotypes are deposited in the National Museum of Natural History (USNM) and paratypes in the Mississippi Entomological Muse-211
