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.

Este grupo incluye miembros con diferentes hábitos alimenticios (saprofagia, fito y zoofagia), lo que aún los posiciona en el ambiente agroindustrial del Valle del Cauca, razón por la cual se planteó determinar la composición y aspectos biocológicos de los escarabajos del plan aluvial monocultivado del Río Cauca (bosque seco tropical Bs-T, 780-1100 mm/año, 960-975 msnm, 24ºC); el estudio biológico incluyó muestreos y observaciones en laboratorio, complementando con revisión de colecciones y literatura; el estudio ecológico (parcelas de caña manejo ecológico (CME), caña convencional (CC), potrero silvopastoril (PSP) y bosque, se basó en cuadrantes (1m2 y 30 cm de profundidad) durante época seca, transición y húmeda. Se aportan datos bioecológicos de las 42 especies consideradas habitantes del plan monocultivado y algunas presumiblemente extintas localmente, estas fueron: Astaena aff. valida, Phyllophaga sericata, P. thoracica, P. impressipyga, Macrodactylus sp., Isonychus sp., Ceraspis sp., Plectris aff. fassli, P. aff. pavida, Pelidnota prasina, Macraspis chrysis, M. nazareti, Paranomala cincta, P. undulata, P. incostans, Leucothyreus femoratus, Cyclocephala lunulata, C. amazona, C. stictica, C. pardolocarnoi, C. melanocephala, Aspidolea fuliginea, Aspidolea singularis, Dyscinetus dubius, Stenocrates bicarinatus, Lycomedes hirtipes, Ligyrus bituberculatus, L. -

Quick Guide for the Identification Of
Quick Guide for the Identification of Maryland Scarabaeoidea Mallory Hagadorn Dr. Dana L. Price Department of Biological Sciences Salisbury University This document is a pictorial reference of Maryland Scarabaeoidea genera (and sometimes species) that was created to expedite the identification of Maryland Scarabs. Our current understanding of Maryland Scarabs comes from “An Annotated Checklist of the Scarabaeoidea (Coleoptera) of Maryland” (Staines 1984). Staines reported 266 species and subspecies using literature and review of several Maryland Museums. Dr. Price and her research students are currently conducting a bioinventory of Maryland Scarabs that will be used to create a “Taxonomic Guide to the Scarabaeoidea of Maryland”. This will include dichotomous keys to family and species based on historical reports and collections from all 23 counties in Maryland. This document should be cited as: Hagadorn, M.A. and D.L.

Zoosystema 35 (4): 537-549. http://dx.doi.org/10.5252/z2013n4a7 ABSTRACT Augosoma centaurus Fabricius, 1775 (Melolonthidae: Dynastinae), one of the largest Scarabaeoid beetles of the Ethiopian Region, is classified in the tribe Dynastini MacLeay, 1819, principally on the basis of morphological characters of the male: large frontal and pronotal horns, and enlargement of fore legs. With the exception of A. centaurus, the 62 species of this tribe belong to ten genera grouped in Oriental plus Australasian and Neotropical regions. We performed cytogenetic studies of A. centaurus and several Asian and Neotropical species of Dynastini, in addition to species belonging to other sub-families of Melolonthidae Leach, 1819 and various tribes of Dynastinae MacLeay, 1819: Oryctini Mulsant, 1842, Phileurini Burmeister, 1842, Pentodontini Mulsant, 1842 and Cyclocephalini Laporte de Castelnau, 1840. The karyotypes of most species were fairly alike, composed of 20 chromosomes, including 18 meta- or sub-metacentric autosomes, one acrocentric or sub-metacentric X-chromosome, and one punctiform Y-chromosome, as that of their presumed common ancestor. -
Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4. -

Despite their many 1543-592X/08/1201-0387$20.00 shapes and sizes, and the multitude of habitats within which they function, animal weapons share many properties: They evolve when males are able to defend spatially restricted critical resources, they are typically the most variable morphological structures of these species, and this variation hon- estly reflects among-individual differences in body size or quality. What is not clear is how, or why, these weapons diverge in form. The potential for male competition to drive rapid divergence in weapon morphology remains one of the most exciting and understudied topics in sexual selection research today. 3*7 INTRODUCTION Sexual selection is credited with the evolution of nature's most extravagant structures, and these include showy male adornments that are attractive to females (ornaments) and an arsenal of outgrowths that function in male-male combat (weapons) (Darwin 1871).
