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.

The Purposes of This Paper Are to Clarify Generic Concepts in New
STUDIES OF THE SUBTRIBE TACHYINA (COLEOPTERA: CARABIDAE: BEMBIDIINI) SUPPLEMENT A: LECTOTYPE DESIGNATIONS FOR NEW WORLD SPECIES, TWO NEW GENERA, AND NOTES ON GENERIC CONCEPTS1 TERRY L. ERWIN National Museum of Natural History, Smithsonian Institution, Washington, D. C. 20560 ABSTRACT•The New World species-group names of the carabid subtribe Tachyina are arranged alphabetically by genus. Lectotype designation are made where necessary and species are assigned accordingly to their proper genus. Two new genera, Costitachys and Meotachys are described. Three species described in the genus Polyderis, testaceolimbata Motschulsky, glabrella Mots., and breviscula Mots., are reassigned to the genus Perigona of the Perigonini. A key is provided to Tachyina genera and notes on generic concepts are given. INTRODUCTION The purposes of this paper are to clarify generic concepts in New World Tachyina, designate lectotypes, list synonymies, provide a key to genera, and describe two new genera. Ail of this became possible after studying the World fauna to determine how New World groups relate to Old World groups. Much of this work has now been done and my series of revisions for the World Tachyina has begun to be issued (Erwin, 1973a, 1974). The work here has been strictly limited without giving reasons for many of the actions taken. Reasons will be provided in forthcoming revisions where space will allow full development of ideas from facts, and analyses of these facts. METHODS During 1971, I was able to study almost all primary type material for New World Tachyina as well as to study numerous Old World forms in the British Museum in London and in the Museum d'Histoire Naturelle in Paris. -

BARR, JR. The University of Kentucky, Lexington Trechoblemus Ganglbauer is a genus of trechine beetles (Tre- chinae: Trechini: Trechina) previously known only from Europe and Asia. It formed the type genus of Jeannel's "S6rie phyl6tique de Trechoblemus". and is generally regarded as closely related to cavernicolous trechines in Japan, the Carpathians and Transylvanian Alps of eastern Europe, and eastern United States (Barr, I969; Jeannel, I928, I962; U6no and Yoshida, I966). The large cave beetle genus Pseudanophthalmus Jeannel, with approximately 75 species in caves of ten eastern States, the monobasic genus Nea- phaenops Jeannel, from Kentucky caves, and the dibasic genus ]gelsonites Valentine, ]rorn Tennessee and Kentucky, are part of the Trechoblemus complex. The apparent restriction of Trechoblemus to Eurasia led previous investigators to conclude that, with respect to the richly diverse trechine fauna in caves of eastern United States, "there are no im- mediate, ancestral genera now present in North America" (Barr, 969, p. 83). Although there is at least one edaphobitic (obligate in soil) species of American Pseudanophthalmus known (P. sylvaticus Barr, I967), in the mountains of West Virginia, it has already lost eyes, wings, and pigment, and merely indicates that many of the "regressive" evolutionary changes in ancestral Pseudanohthal- mus may have taken place in the soil or deep humus before the beetles became restricted to caves. Most of the species of Pseuda- nophthalmus from eastern Europe (Barr, 964) are also eyeless edaphobites. -

Published by the Genetics Society of America. 2 9 Abstract 10 Measuring genome size across different species can yield important insights into 11 evolution of the genome and allow for more informed decisions when designing next-generation 12 genomic sequencing projects. New techniques for estimating genome size using shallow 13 genomic sequence data have emerged which have the potential to augment our knowledge of 14 genome sizes, yet these methods have only been used in a limited number of empirical studies. In 15 this project, we compare estimation methods using next-generation sequencing (k-mer methods 16 and average read depth of single-copy genes) to measurements from flow cytometry, a standard 17 method for genome size measures, using ground beetles (Carabidae) and other members of the 18 beetle suborder Adephaga as our test system. We also present a new protocol for using read- 19 depth of single-copy genes to estimate genome size. -

Adult Seasonality, Feeding and Recruitment. by Russell M. NORTON, Thomas C. KANE, Thomas L. POULSON INTRODUCTION This is the second of two papers dealing with the ecology of Neaphaenops. The procedure and a general introduction will be found in the first paper. RESULTS A. Adult Recruitment Recruitment of teneral adults in both Marion Avenue and Edwards Avenue shows a marked seasonality (Figure 7). Teneral adults emerge chiefly in late spring through early fall, although there is some emergence throughout the year. B. Adult Seasonality Census data for all adult Neaphaenops from the Marion Avenue and Edwards Ave- nue study areas are presented in Figures 5 and 6, respectively. Both areas show a summer through early fall population maximum coincident with the recruitment of teneral adults into the population, and a decrease through the rest of the year. Sex ratio data for both areas are presented in Table 3. Although the sex ratio for tenerals is 1: 1 (N)400), the sex ratio for fully sclerotized adults on sandy areas changes seasonally to a female majority (up to 2: I) just prior to the recruitment of sclerotized tenerals. C Adult Feeding The 46 feeding observations recorded for Neaphaenops to date are listed in Table 2. Of these, the ne plus ultra is a female in copula feeding on a Hadenoecus nymph. The two observations of Neaphaenops feeding on non cave-limited organisms were both made near entrances. About one third of the predated first instar Hadenoecus nymphs appeared to have been captured during emergence since they seemed to still be partially bound by the vitelline membrane. -

E-mail: [email protected]; [email protected] 2Laboratory for Insect Pathology, Department of Entomology, LSU Agricultural Center, Baton Rouge, Louisiana, 70803, USA. E-mail: [email protected] Abstract The Anillinus langdoni–species group is characterized and two new species are described, Anillinus cieglerae Sokolov and Carlton sp. nov. and A. pusillus Sokolov and Carlton sp. nov., both from Great Smoky Mountains National Park. The langdoni–group includes four species at present, three apparently endemic to the Great Smoky Mountains and adjacent mountains of western North Carolina/Tennessee, and a fourth from South Mountains of middle North Carolina. They are distinguished mainly using characters of the male genitalia and to a lesser extent, differences in shapes of female sper- mathecae. Phylogenetic analyses based on aedeagal morphology and COI gene sequences yielded conflicting results, with the later providing a phylogeny that was more parsimonious with expectations based on geographic distributions. Speciation within the group may derive from ecological constraints and altitudinal fluctuations of habitat corridors dur- ing past climate changes combined with the impact of local watersheds as fine scale isolating mechanisms. Key words: Coleoptera, Adephaga, Carabidae, Anillinus, South Appalachians, new species, taxonomy, identification key, COI gene sequences, phylogeography Introduction The genus Anillinus Casey is one of the most diverse genera of carabid beetles in the Southern Appalachian region of eastern United States. -

RELATIONSHIPS BETWEEN DEAD WOOD AND ARTHROPODS IN THE SOUTHEASTERN UNITED STATES by MICHAEL DARRAGH ULYSHEN (Under the Direction of James L. Hanula) ABSTRACT The importance of dead wood to maintaining forest diversity is now widely recognized. However, the habitat associations and sensitivities of many species associated with dead wood remain unknown, making it difficult to develop conservation plans for managed forests. The purpose of this research, conducted on the upper coastal plain of South Carolina, was to better understand the relationships between dead wood and arthropods in the southeastern United States. In a comparison of forest types, more beetle species emerged from logs collected in upland pine-dominated stands than in bottomland hardwood forests. This difference was most pronounced for Quercus nigra L., a species of tree uncommon in upland forests. In a comparison of wood postures, more beetle species emerged from logs than from snags, but a number of species appear to be dependent on snags including several canopy specialists. In a study of saproxylic beetle succession, species richness peaked within the first year of death and declined steadily thereafter. However, a number of species appear to be dependent on highly decayed logs, underscoring the importance of protecting wood at all stages of decay. In a study comparing litter-dwelling arthropod abundance at different distances from dead wood, arthropods were more abundant near dead wood than away from it. In another study, ground- dwelling arthropods and saproxylic beetles were little affected by large-scale manipulations of dead wood in upland pine-dominated forests, possibly due to the suitability of the forests surrounding the plots. -

Holocene Palaeoenvironmental Reconstruction Based on Fossil Beetle Faunas from the Altai-Xinjiang Region, China
Holocene palaeoenvironmental reconstruction based on fossil beetle faunas from the Altai-Xinjiang region, China Thesis submitted for the degree of Doctor of Philosophy at the University of London By Tianshu Zhang February 2018 Department of Geography, Royal Holloway, University of London Declaration of Authorship I Tianshu Zhang hereby declare that this thesis and the work presented in it is entirely my own. Where I have consulted the work of others, this is always clearly stated. Signed: Date: 25/02/2018 1 Abstract This project presents the results of the analysis of fossil beetle assemblages extracted from 71 samples from two peat profiles from the Halashazi Wetland in the southern Altai region of northwest China. The fossil assemblages allowed the reconstruction of local environments of the early (10,424 to 9500 cal. yr BP) and middle Holocene (6374 to 4378 cal. yr BP). In total, 54 Coleoptera taxa representing 44 genera and 14 families have been found, and 37 species have been identified, including a new species, Helophorus sinoglacialis. The majority of the fossil beetle species identified are today part of the Siberian fauna, and indicate cold steppe or tundra ecosystems. Based on the biogeographic affinities of the fossil faunas, it appears that the Altai Mountains served as dispersal corridor for cold-adapted (northern) beetle species during the Holocene. Quantified temperature estimates were made using the Mutual Climate Range (MCR) method. In addition, indicator beetle species (cold adapted species and bark beetles) have helped to identify both cold and warm intervals, and moisture conditions have been estimated on the basis of water associated species. -
A New Species of Bembidion LATREILLE from Nemrut Dağ

TOLEDANO &K.RÉBL Abstract Bembidion (Ocydromus) nemrutdagi sp.n. from the Nemrut Da÷ (Turkey, AdÕyaman Prov.) is described. Its nearest relative, B. cordicolle DUVAL, 1851, is transferred to the subgen. Ocydromus CLAIRVILLE, 1806 s.l. (sensu KRYZHANOVSKIJ et al. 1995). The systematic relationships of some species groups are discussed. Key words: Coleoptera, Carabidae, Bembidiina, Bembidion, Ocydromus, Turkey, taxonomy. Introduction While studying Turkish Bembidion LATREILLE, 1802 we detected two specimens extremely similar to B. cordicolle DUVAL, 1851, from which they could be distinguished by the number of elytral pores. After comparison with the other species occurring in the area and after a thorough literature study we concluded that these specimens represent an undescribed species. Material and methods This paper is based on the study of 60 specimens belonging to the species dealt with herein and several hundreds of other specimens belonging to the subgen.
