Will, Kipling W.;
Revista Brasileira de Entomologia , 2004, DOI: 10.1590/S0085-56262004000400003
Abstract: two species are added to the previously monotypic genus metoncidus bates, 1871 (carabidae, loxandrini): m. epiphytus sp. nov. (type locality peru: loreto, cocha shinguito) and m. gracilus sp. nov. (type locality peru: tambopata, madre de dios). information allowing identification of the genus from among other south american carabid genera and a key to adult individuals of metoncidus species are provided.

Papéis Avulsos de Zoologia (S?o Paulo) , 2011, DOI: 10.1590/S0031-10492011002100001
Abstract: the genus rhopalessa is revised and divided into two groups: the clavicornis-group with r. clavicornis (bates, 1873), r. demissa (melzer, 1934), r. hirticollis (zajciw, 1958), r. moraguesi (tavakilian & pe?aherrera-leiva, 2003), r. pilosicollis (zajciw, 1966) and r. subandina sp. nov.; and the rubroscutellaris-group with r. durantoni (pe?aherrera-leiva & tavakilian, 2004) and r. rubroscutellaris (tippmann, 1960). two species were synonymyzed with r. clavicornis: ommata (rhopalessa) nigrotarsis fisher, 1937 and ommata (rhopalessa) nigricollis zajciw, 1969.

Taxonomic synopsis of the subtribe Physoderina (Coleoptera, Carabidae, Lebiini), with species revisions of eight genera  [cached]
Hongliang Shi,Hongzhang Zhou,Hongbin Liang
ZooKeys , 2013, DOI: 10.3897/zookeys.284.3983
Abstract: Ten genera of Physoderina from the Oriental Region are diagnosed and described, and twenty six species representing eight genera (Paraphaea Bates, Anchista Nietner, Metallanchista gen. n., Diamella nom. n., Allocota Motschulsky, Orionella Jedli ka, Endynomena Chaudoir and Dasiosoma Britton (Oriental species only)) are revised. Keys to genera and species are provided, along with distribution maps, habitus images, photographs of the name-bearing types, and illustrations of male and female genitalia of available species. The female internal reproductive system is illustrated for fourteen species. Two genera, Anchista and Taicona, previously placed in Calleidina, are moved into Physoderina. One new genus is described: Metallanchista, gen. n. (type species M. laticollis, sp. n.). Two new generic synonyms are proposed: Taicona Bates, 1873, junior synonym of Allocota Motschulsky, 1859; Teradaia Habu, 1979a, junior synonym of Dasiosoma Britton, 1937. A new generic replacement name is proposed: Diamella, nom. n. for Dianella Jedli ka, 1952 (junior homonym of Dianella Gude, 1913). The status of Paraphaea Bates, 1873 is resurrected from synonym of Anchista Nietner, 1856. Five new species are described: Paraphaea minor Shi & Liang, sp. n. (Hoa-Binh, Tonkin, Vietnam), Anchista pilosa Shi & Liang, sp. n. (Chikkangalur, Bangalore, India), Metallanchista laticollis Shi & Liang, sp. n. (PhaTo env., Chumphon prov., Thailand), Allocota bicolor Shi & Liang, sp. n. (Dengga to Mafengshan, Ruili, Yunnan, China), Dasiosoma quadraticolle Shi & Liang, sp. n. (Menglun Botanical Garden, Yunnan, China). Fourteen new combinations are proposed: Paraphaea binotata (Dejean, 1825), comb. n. from Anchista; Paraphaea formosana (Jedli ka, 1946), comb. n. from Anchista; Paraphaea philippinensis (Jedli ka, 1935b), comb. n. from Allocota; Metallanchista perlaeta (Kirschenhofer, 1994), comb. n. from Allocota; Physodera andrewesi (Jedli ka, 1934), comb. n. from Allocota; Diamella cupreomicans (Oberthür, 1883), comb. n. from Physodera; Diamella arrowi (Jedli ka, 1935a), comb. n. from Allocota; Allocota aurata (Bates, 1873), comb. n. from Taicona; Dasiosoma bellum (Habu, 1979a), comb. n. from Teradaia; Dasiosoma indicum (Kirschenhofer, 2011), comb. n. from Dianella; Dasiosoma maindroni (Tian & Deuve, 2001), comb. n. from Lachnoderma; Dasiosoma hirsutum (Bates, 1873), comb. n. from Lachnoderma; Orionella discoidalis (Bates, 1892), comb. n. from Anchista; Orionella kathmanduensis (Kirschenhofer, 1994), comb. n. from Lachnoderma. Five names are newly placed as junior synonyms: Paraphaea eurydera (Ch
Rainforest understory beetles of the Neotropics: Mizotrechus Bates 1872, a generic synopsis with descriptions of new species from Central America and northern South America (Coleoptera, Carabidae, Perigonini)
Terry Erwin
ZooKeys , 2011, DOI: 10.3897/zookeys.145.2274
Abstract: Information on the single previously described species, Mizotrechus novemstriatus Bates 1872 (type locality: Brazil – Amazonas, Tefé), is updated and 17 new species for the genus from Nicaragua, Costa Rica, Panamá, Colombia, Venezuela, and Guyane are described. The species records in the literature and on determined specimens in some collections of M. novemstriatus Bates from Central America are not that species; currently, M. novemstriatus is known only from its type locality in Amazonian Brazil. For the new species described, their known general distributions are as follows: Mizotrechus batesi sp. n. (Guyane), Mizotrechus bellorum sp. n. (Guyane), Mizotrechus brulei sp. n. (Guyane), Mizotrechus belevedere sp. n. (Guyane), Mizotrechus costaricensis sp. n. (Costa Rica), Mizotrechus dalensi sp. n. (Guyane), Mizotrechus edithpiafae sp. n. (provenance unknown), Mizotrechus fortunensis sp. n. (Panamá), Mizotrechus gorgona. sp. n. (Colombia), Mizotrechus grossus sp. n. (Guyane), Mizotrechus jefe sp. n. (Panamá), Mizotrechus marielaforetae sp. n. (Guyane), Mizotrechus minutus sp. n. (Guyane), Mizotrechus neblinensis sp. n. (Guyane, Venezuela), Mizotrechus poirieri sp. n. (Guyane), and Mizotrechus woldai sp. n. (Panamá). Long-term use of flight intercept traps in Guyane provided so many new species that apparently the use of FITs is the way to collect adults of this taxon, previously known from very few specimens. Many more species of this genus can be expected to be discovered throughout the Neotropics; the present contribution is a preliminary synopsis with identification key and adult images of all known species. Likely numerous species are yet to be discovered throughout tropical climes.
Calleida desenderi, new species from Ecuador (Coleoptera, Carabidae, Lebiinae)  [cached]
Achille Casale
ZooKeys , 2011, DOI: 10.3897/zookeys.100.1522
Abstract: Calleida desenderi Casale, sp. n., is described from Ecuador, Napo Province, surroundings of San Rafael. The new taxon is mostly characterized by the head and appendages rufous, the disc of elytra with marked metallic green reflection, the median lobe of aedeagus ring-like, and the endophallus with a long, twisted flagellum. A key for identification of the closer Neotropical species described so far is also provided.

Ground beetles of the Ukraine (Coleoptera, Carabidae)  [cached]
Alexander Putchkov
ZooKeys , 2011, DOI: 10.3897/zookeys.100.1545
Abstract: A review of the ground beetles of the Ukrainian fauna is given. Almost 750 species from 117 genera of Carabidae are known to occur in the Ukraine. Approximately 450 species of ground beetles are registered in the Carpathian region. No less than 300 species of ground beetles are found in the forest zone. Approximately 400 species of Carabidae present in the forest-steppe zone are relatively similar in species composition to those in the forest territories. Some 450 species of Carabidae are inhabitants of the steppe zone. Representatives of many other regions of heterogeneous biotopes such as forest, semi desert, intrazonal, etc. can be found in the steppe areas. The fauna of Carabidae (ca. 100 species) of the lowlands of southern Ukraine (sandy biotopes), situated mostly in the Kherson region, is very peculiar. The fauna of the Crimean mountains contains about 300 species. Conservation measures for the Carabidae are discussed.

D. H. Barkhuff,S. P. Wells,T. Averett,D. H. Beck,E. J. Beise,D. Cheever,G. Dodson,S. Kowalski,R. D. McKeown,B. A. Mueller,M. Pitt,D. Spayde,C. Tschalaer,A. Zolfaghari
Physics , 1999, DOI: 10.1016/S0168-9002(00)00260-6
Abstract: We report the development and implementation of an energy feedback system for the MIT/Bates Linear Accelerator Center. General requirements of the system are described, as are the specific requirements, features, and components of the system unique to its implementation at the Bates Laboratory. We demonstrate that with the system in operation, energy fluctuations correlated with the 60 Hz line voltage and with drifts of thermal origin are reduced by an order of magnitude.
