A Review of Perlinella Banks (Plecoptera: Perlidae) BORIS C. KONDRATIEFF,l RALPH F. KIRCHNER,2.3 AND KENNETH W. STEWART4 Ann. Entomol. Soc. Am. 81(1): 19-27 (1988) ABSTRACT The Nearctic stonefly genus Perlinella Banks is reviewed; three valid species are recognized. Perlinella drymo (Newman) and Perlinella ephyre (Newman) are widespread east of the Rocky Mountains, whereas Perlin ella zwicki, n. sp. (P. jumipennis of Zwick 1971), is restricted to the southeastern Coastal Plain. Perlinella jumipennis (Walsh) is replaced as a synonym of Perlinella ephyre. Keys for adults and nymphs are provided, and the nymph of P. zwicki is described for the first time. Male drumming calls of Perlin della drymo and Perlinella ephyre are described.

E-mail: [email protected], [email protected] 2Weihai Li, Department of Plant Protection, Henan Institute of Science and Technology, Xinxiang, Henan, 453003 China. E-mail: [email protected] Abstract. The monotypic Taiwanese genus Mesoperla Klapálek, 1913 is redescribed on the basis of a male syntype specimen, and its affinities are re-evaluated. The single female type specimen of further two Oriental monotypic genera, Kalidasia Klapálek, 1914 and Nirvania Klapálek, 1914, are confirmed to be lost or destroyed respectively; both genera are considered as nomina dubia. The Sichuan endemic Acroneuria grahami Wu & Claassen, 1934 is redescribed on the basis of male holotype. Distinctive characters of the genus Brahmana Klapálek, 1914 consisting of five, inadequately known Oriental species are discussed. Flavoperla needhami (Klapálek, 1916) and Sinacroneuria sinica (Yang & Yang, 1998) comb. novae are suggested for an Indian species originally described in Gibosia Okamoto, 1912 and a Chinese species originally described in Acroneuria Pictet, 1841. At present, 62 species of Acroneuriinae, classified in 10 valid genera are reported from the Oriental Realm but 29 species are inadequately known. A key is presented to distinguish males of the Asian Acroneuriinae genera. Asian distribution of each genera are detailed and depicted on a map.

  • This Table Contains a Taxonomic List of Benthic Invertebrates Collected from Streams in the Upper Mississippi River Basin Study
    This table contains a taxonomic list of benthic invertebrates collected from streams in the Upper Mississippi River Basin study unit as part of the USGS National Water Quality Assessemnt (NAWQA) Program. Invertebrates were collected from woody snags in selected streams from 1996-2004. Data Retreival occurred 26-JAN-06 11.10.25 AM from the USGS data warehouse (Taxonomic List Invert http://water.usgs.gov/nawqa/data). The data warehouse currently contains invertebrate data through 09/30/2002. Invertebrate taxa can include provisional and conditional identifications. For more information about invertebrate sample processing and taxonomic standards see, "Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory -- Processing, taxonomy, and quality control of benthic macroinvertebrate samples", at << http://nwql.usgs.gov/Public/pubs/OFR00-212.html >>. Data Retrieval Precaution: Extreme caution must be exercised when comparing taxonomic lists generated using different search criteria. This is because the number of samples represented by each taxa list will vary depending on the geographic criteria selected for the retrievals. In addition, species lists retrieved at different times using the same criteria may differ because: (1) the taxonomic nomenclature (names) were updated, and/or (2) new samples containing new taxa may Phylum Class Order Family Subfamily Tribe Genus Species Taxon Porifera Porifera Cnidaria Hydrozoa Hydroida Hydridae Hydridae Cnidaria Hydrozoa Hydroida Hydridae Hydra Hydra sp.

These insects had small wing-like lateral expansions of the prothorax, and a fairly well- developed posterior (concave) median vein in both wings, both of which have been lost in modern stoneflies. Developments in some of the mor- phological features which have been most studied are as follows: Nymphal mouth parts: The holognathous families are characterized by bulky mandibles, by short thick palpi, and by having the paraglossae and glossae of the labium about equal in length.

Procedures for storing reference specimens are also described. I. Preparing the Sample for Processing Processing procedures apply to all benthic samples. This is an important and time-consuming step. Particular care should be taken to ensure that samples are being processed thoroughly and efficiently. The purpose of sorting is to remove invertebrates from other material in the sample. Procedure: A. Sample processing begins by pouring the original field sample into a USGS standard sieve (500-µm) placed in a catch pan. The preservative that is drained from the sample should be placed back in the original sample container for eventual rehydration of remaining sample debris that is not sorted during the subsample procedure described below. B. Rinse the sample contents in the sieve with tap water to flush the residual preservative. Large debris material (>2 cm; i.e. leaves, sticks, rocks) should be removed by hand and rinsed into the sieve.

Morse5 Abstract - Great Smoky Mountains National Park (GSMNP), situated on the moun- tainous border of North Carolina and Tennessee, is recognized as one of the most highly diverse protected areas in the temperate region. In order to provide baseline data for the scientifi c management of GSMNP, an All Taxa Biodiversity Inventory (ATBI) was initiated in 1998. Among the goals of the ATBI are to discover the identity and distribution of as many as possible of the species of life that occur in GSMNP. The authors have concentrated on the orders of completely aquatic insects other than odonates. We examined or utilized others’ records of more than 53,600 adult and 78,000 immature insects from 545 locations. At present, 469 species are known from GSMNP, including 120 species of Ephemeroptera (mayfl ies), 111 spe- cies of Plecoptera (stonefl ies), 7 species of Megaloptera (dobsonfl ies, fi shfl ies, and alderfl ies), and 231 species of Trichoptera (caddisfl ies). Included in this total are 10 species new to science discovered since the ATBI began. Introduction Great Smoky Mountains National Park (GSMNP) is situated on the border of North Carolina and Tennessee and is comprised of 221,000 ha. GSMNP is recognized as one of the most diverse protected areas in the temperate region (Nichols and Langdon 2007).
