Without their cooperation this research could not have been completed. I would like to thank Nadine Duperre for graciously and patiently providing the male genitalia sketches. Thank you to Robert Jones, Moises Perez and Jesus Luna Cozar (Chuy) for showing me a great time in Mexico. I would also like to thank Francois Génier for teaching me the wonderful ways of Mantis and how to use it to its’ fullest potential. Your determination, enthusiasm and uncanny attention to detail have taught me how to properly take care of natural history collections. I always know that if there is a problem or a more efficient way to do something, you will find the solution to it, even if it means you have to construct it yourself. I owe Andrew Smith more than the few words I will say here. He has probably the biggest heart, as well as, the most enthusiasm for all things entomology,

  • A Review of the Trachyloeini of America North of Mexico (Coleoptera, Curculionidae)
    A REVIEW OF THE TRACHYLOEINI OF AMERICA NORTH OF MEXICO (COLEOPTERA, CURCULIONIDAE) ELBERT L. SLEEPER Department of Zoology and Entomology, The Ohio State University, Columbus 10 This paper is the result of a study started originally on the genus Cercopeus Schonherr. However, to establish the proper relationship of the related genera it became necessary to review all the genera and species in the tribe. The author hopes that this review will enable other workers to determine their material in this group which heretofore has been rather neglected. The author feels that further study should be made in Western United States for more members of this tribe. DISCUSSION The tribe Trachyphloeini is typified by the absence of ocular lobes, the eyes always free and rounded; the scrobes are variable, never at the same time linear and directed beneath; the outer segments of funicle moniliform; elytra scarcely surpassing the width of the prothorax at base; humeral angles rounded; metas- ternum short; the intercoxal lobe on the first abdominal segment large and broad; the corbels of the posterior tibiae open and the tarsal claws free. All members of this tribe known to science are apterous. The larvae of all species breed in the roots of herbaceous plants and trees. They are potentially of economic importance, particularly in areas which have been recently cleared for cultivation of agricultural crops. Occasionally the adults will be found feeding on foliage during the day, but with few exceptions they are night feeders, spending the day in leaf litter and rubbish around the host plant. All of the species probably over-winter as an imago.

    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.

  • The Ohio Journal of Science — Index 1951-1970
    THE OHIO JOURNAL OF SCIENCE — INDEX 1951-1970 JANE L. FORSYTH AND CHRISTINE M. GORTA Department of Geology, Bowling Green State University, Bowling Green, Ohio 43403 INTRODUCTION It is almost 20 years since the first General Index to The Ohio Journal of Science, which covered the issues from the beginning (1900) through 1950, was published (Miller, E. M., 1953, published by The Ohio State University and The Ohio Academy of Science). It is time, therefore, for another general index, dealing with issues appearing since 1950. This is that index. Unlike the first index, there is no separate listing of full references by author; rather, this is simply a combining of all the entries from all the yearly indexes from 1951 through 1972. Basically these original entries remain unchanged here, though mistakes found in a few were corrected, and some have been slightly reworded in order to fit better into this multiple listing. Entries relating to book reviews occur only for the years of 1963 through 1970, because book reviews were not included in the earlier indexes. It should also be noted that, though a few of these books represent merely a reprinting of older, out-of-date books, these books are not so identified in the entries in this index. Preparation of this index has been mostly handled by Miss Christine M. Gorta, under the direction of Dr. Jane L. Forsyth, Editor of The Ohio Journal of Science from 1964 to 1973, but others have also contributed to this work—mainly Misses Lauran Boyles and Laura Witkowski—contributers whose efforts are gratefully acknowledged.

  • The Cave-Inhabiting Beetles of Cuba (Insecta: Coleoptera): Diversity, Distribution and Ecology
    Stewart B. Peck, Amador E. Ruiz-Baliú and Gabriel F. Garcés González- The Cave-inhabiting Beetles of Cuba (Insecta: Coleoptera): Diversity, Distribution and Ecology. Journal of Cave and Karst Studies 60(3): 156-166. THE CAVE-INHABITING BEETLES OF CUBA (INSECTA: COLEOPTERA): DIVERSITY, DISTRIBUTION AND ECOLOGY STEWART B. PECK Department of Biology, Carleton University, Ottawa, Ontario, K1S 5B6 CANADA, [email protected] AMADOR E. RUIZ-BALIÚ Departmento de Biología, Universidad de Oriente, Santiago de Cuba, CUBA GABRIEL F. GARCÉS GONZÁLEZ Centro Oriental de Ecosystemas y Biodiversidad, Ministerio de la Ciencia, Tecnología y Medio Ambiente, Santiago de Cuba, CUBA The known cave-inhabiting beetle fauna of Cuba is summarized. Fifty-three species have been found in 70 low elevation caves in 11 provinces. Distribution of species by family is: Carabidae, 10; Dytiscidae, 4; Gyrinidae, 2; Hydrophilidae, 2; Histeridae, 5; Leiodidae, 2; Ptiliidae, 3; Staphylinidae, 1; Scarabaeidae, 4; Elateridae, 2; Lampyridae, 1; Nitidulidae, 1; Cerylonidae, 1; Tenebrionidae, 12; and Curculionidae, 3. Twenty-four of the species are judged to be accidental cave inhabitants. The remain- ing 29 species can be placed in the following ecological-evolutionary categories: trogloxenes, 3 species; first-level troglophiles, 21 species; second-level troglophiles (=unmodified neotroglobites), 5 species. No true troglobites are known (i.e., none of the species is morphologically specialized for cave life). About 59% of the non-accidental inhabitants are endemic to Cuba. The taxonomic composition is similar to that in caves in other West Indian Islands, and impoverished when compared to Neotropical continental caves. The abundance of food (bat guano) seems a prime factor preventing selection for cave-special- ization in lowland West Indian and continental Neotropical cave beetles.

This is achieved using a phylogenetic approach incorporating the largest datamatrix yet employed for weevil molecular systematics, and includes an investigation into the prospect of obtaining short phylogenetically informative amplicons from archival museum specimens. Newly obtained DNA sequence data is analysed from a variety of mitochondrial and nuclear loci, including 92 mitogenomes assembled through the approach of next-generation sequencing of pooled genomic DNA. The resulting trees are used to test previous morphological- and molecular-based hypotheses of weevil relationships and classification schemes. Mitogenomic-derived trees reveal topologies that are highly congruent with previous molecular studies, but that conflict with some morphological hypotheses. Strong nodal support strengthens inferences into the relationships amongst most weevil families and suggests that the largest family, the Curculionidae, is monophyletic, if the subfamily Platypodinae is excluded.

We performed Bayesian and Maximum Parsimony combined phylogenetic analyses with the main objective of testing higher-level relationships and the naturalness of the major Neotropical and Southern South American (Patagonia and Andes) tribes, including some members from other regions. We compiled a data matrix of 67 terminal units with 63 Entiminae species, as well as four outgroup taxa from Cyclominae, by 3522 molecular (from nuclear 18S rDNA and 28S rDNA, and mitochondrial 16S rDNA and COI gene sequences) and 70 morphological characters. The resulting trees recover a clade Entiminae with a monophyletic Cylydrorhinini and Premnotrypes branching off early.
