In this paper I accept the Whitehead/ Nichols proposals for classification of the species of the Key words: Coleoptera, Carabidae, Clivinini, Ardistomina, new ardistomine complex at the supraspecific level.

The major focus of this paper, however, is description and illustration of This represents the first paper in a series of studies diagnostic features of new species of Ardistomis from devoted to elucidation of the taxonomic structure ofthe Central and northern South America.

Sem qualquer pretensão de esgotar um assunto tão vasto, um dos objetivos principais deste guia básico de identificação é apresentar e caracterizar esse grande grupo taxonômico de maneira didática e objetiva. Este guia de identificação foi elaborado para auxiliar os técnicos e profissionais de várias áreas de conhecimento nos trabalhos de campo e nas vistorias técnicas realizadas pelo Ibama. É preciso esclarecer que este guia não pretende formar “especialista”, mesmo porque para tanto seriam necessários muitos anos de dedicação e aprendizado contínuo. Longe desse intuito, pretende- se apenas que este trabalho sirva para despertar o interesse quanto à conservação dos invertebrados de cavernas (meio hipógeo) e também daqueles que vivem no ambiente externo (meio epígeo).

  • The Beetle Fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and Distribution
    INSECTA MUNDI, Vol. 20, No. 3-4, September-December, 2006 165 The beetle fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and distribution Stewart B. Peck Department of Biology, Carleton University, 1125 Colonel By Drive, Ottawa, Ontario K1S 5B6, Canada stewart_peck@carleton. ca Abstract. The beetle fauna of the island of Dominica is summarized. It is presently known to contain 269 genera, and 361 species (in 42 families), of which 347 are named at a species level. Of these, 62 species are endemic to the island. The other naturally occurring species number 262, and another 23 species are of such wide distribution that they have probably been accidentally introduced and distributed, at least in part, by human activities. Undoubtedly, the actual numbers of species on Dominica are many times higher than now reported. This highlights the poor level of knowledge of the beetles of Dominica and the Lesser Antilles in general. Of the species known to occur elsewhere, the largest numbers are shared with neighboring Guadeloupe (201), and then with South America (126), Puerto Rico (113), Cuba (107), and Mexico-Central America (108). The Antillean island chain probably represents the main avenue of natural overwater dispersal via intermediate stepping-stone islands. The distributional patterns of the species shared with Dominica and elsewhere in the Caribbean suggest stages in a dynamic taxon cycle of species origin, range expansion, distribution contraction, and re-speciation.

    30 THE GREAT LAKES ENTOMOLOGIST Vol. 42, Nos. 1 & 2 An Annotated Checklist of Wisconsin Ground Beetles (Coleoptera: Carabidae) Peter W. Messer1 Abstract A survey of Carabidae in the state of Wisconsin, U.S.A. yielded 87 species new to the state and incorporated 34 species previously reported from the state but that were not included in an earlier catalogue, bringing the total number of species to 489 in an annotated checklist. Collection data are provided in full for the 87 species new to Wisconsin but are limited to county occurrences for 187 rare species previously known in the state. Recent changes in nomenclature pertinent to the Wisconsin fauna are cited. ____________________ The Carabidae, commonly known as ‘ground beetles’, with 34, 275 described species worldwide is one of the three most species-rich families of extant beetles (Lorenz 2005). Ground beetles are often chosen for study because they are abun- dant in most terrestrial habitats, diverse, taxonomically well known, serve as sensitive bioindicators of habitat change, easy to capture, and morphologically pleasing to the collector. North America north of Mexico accounts for 2635 species which were listed with their geographic distributions (states and provinces) in the catalogue by Bousquet and Larochelle (1993). In Table 4 of the latter refer- ence, the state of Wisconsin was associated with 374 ground beetle species. That is more than the surrounding states of Iowa (327) and Minnesota (323), but less than states of Illinois (452) and Michigan (466). The total count for Minnesota was subsequently increased to 433 species (Gandhi et al. 2005). Wisconsin county distributions are known for 15 species of tiger beetles (subfamily Cicindelinae) (Brust 2003) with collection records documented for Tetracha virginica (Grimek 2009).

  • The Response of Beetles to Group Selection Harvesting in A
    THE RESPONSE OF BEETLES TO GROUP SELECTION HARVESTING IN A SOUTHEASTERN BOTTOMLAND HARDWOOD FOREST by MICHAEL DARRAGH ULYSHEN (Under the Direction of James L. Hanula) ABSTRACT The environmental protection and sustainable management of our remaining forests are increasingly important concerns. Group selection harvesting is an uneven-aged forest management practice that removes patches of desirable trees to create small openings mimicking natural disturbances. To determine the effects of this technique on beetles, malaise and pitfall traps were placed at the center, edge, and in the forest surrounding artificially created gaps of different size (0.13, 0.26, and 0.50 ha) and age (1 and 7 years) in a South Carolina bottomland hardwood forest. Beetles were generally more abundant and species rich in the centers of younger gaps than in the centers of older gaps or in the forest surrounding them. There were relatively few differences in the abundance and richness of beetles between old gaps and the surrounding forest but species composition differed considerably. These differences may be explained by the uneven distribution of various resources.

While much research has focused on the effects of noise on acoustic communication, here, we present the first study concerned with anthropogenic noise and foraging behaviour. We chose the greater mouse-eared bat (Myotis myotis) as a model species because it represents the especially vulnerable group of gleaning bats that rely on listening for prey rustling sounds to find food (i.e. ʻpassive listeningʼ). In a choice experiment with two foraging compartments, we investigated the influence of background noise on foraging effort and foraging success. We tested the hypotheses that: (1) bats will avoid foraging areas with particularly loud background noise; and (2) the frequency–time structure of the noise will determine, in part, the degree to which it deters bats.
