Whitehouse 2020 Name: Ryan J. Whitehouse ABSTRACT Date of Degree: May 1, 2020 Institution: Mississippi State University Major Field: Agricultural Life Sciences Major Professor: Richard L. Brown Title of Study: Biodiversity of Bariditae (Coleoptera: Curculionidae: Conoderinae) in Mississippi Pages in Study: 262 Candidate for Degree of Master of Science A survey of Bariditae in Mississippi resulted in records of 75 species in 32 genera and included two undescribed species and 36 new state records. An additional two species were recognized as possibly occurring in Mississippi as well. Diagnoses for all of the genera and species in the state are provided and keys to the genera as well as all of the species were made. Species were found in every county within Mississippi and are representative of the Bariditae fauna of the southeastern United States. Open, prairie-like habitats and aquatic wetland habitats were the habitats with the highest biodiversity of Bariditae in the state. Species of Baris, Geraeus, Linogeraeus, and Odontocorynus, were found in the highest numbers and Linogeraeus and Sibariops were found to be the most speciose genera in the state. Sibariops amica, S. benigna, and S. houstoni, are proposed as new synonyms of S. concinna.

Prosta 290 D/2, 25-385 Kielce, Poland; [email protected] * Correspondence: [email protected] Simple Summary: Euryommatus mariae is a legendary weevil species in Europe, first described in the 19th century and not collected through the 20th century. Though rediscovered in the 21st century at few localities in Poland, Austria, and Germany, it remains one of the rarest of European weevils, and its biology is unknown. We present the first descriptions of the larva and pupa of E. mariae, and confirm its saproxylic lifestyle. The differences and similarities between immatures of E. mariae and the genera Coryssomerus, Cylindrocopturus and Eulechriopus are discussed, and a list of larval characters common to all Conoderitae is given. The characters of adult postabdomen are described and illustrated for the first time for diagnostic purposes. Our study confirmed the unusual structure of the male endophallus, equipped with an extremely long ejaculatory duct enclosed in a peculiar fibrous conduit, not seen in other weevils. We hypothesize that the extraordinarily long Citation: Gosik, R.; Wanat, M.; Bidas, and spiral spermathecal duct is the female’s evolutionary response to the male’s extremely long M.

Twenty-seven species are found in the Paleocene, 442 in the Eocene and 94 in the Oligocene. The greatest diversity of Curculionoidea is described from the Eocene of Europe and North America. The richest faunas are known from Eocene localities, Florissant (177 species), Baltic amber (124 species) and Green River formation (75 species). The family Curculionidae dominates in all Paleogene localities. Weevil species associated with herbaceous vegetation are present in most localities since the middle Paleocene. A list of Curculionoidea species and their distribution by location is presented. Keywords: Coleoptera; Curculionoidea; fossil weevil; faunal structure; Paleocene; Eocene; Oligocene 1. Introduction Research into the biodiversity of the past is very important for understanding the development of life on our planet. Insects are one of the Main components of both extinct and recent ecosystems. Coleoptera occupied a special place in the terrestrial animal biotas of the Mesozoic and Cenozoics, as they are characterized by not only great diversity but also by their ecological specialization.

  • A Synopsis of the Genus Barinus Casey in North America (Coleoptera Curculionidae)
    A SYNOPSIS OF THE GENUS BARINUS CASEY IN NORTH AMERICA (COLEOPTERA CURCULIONIDAE) ELBERT L. SLEEPER Department of Zoology and Entomology, The Ohio State University, Columbus 10 While studying the members of the genera Barinus Casey and Barilepton LeConte recently, the author discovered several new forms and not a little confusion as to the limits of these genera. The species falling in the genus Barinus are discussed here. Those falling in Barileptcm and related genera with connate claws will be discussed in a forthcoming paper. The two afore mentioned genera are very alike in general appearance and in most morphological characters, thus leading to considerable confusion. The only reliable character for separating the two genera, which can be easily distinguished, is the form of the tarsal claws. In Barilepton the last tarsal segment is single and not in the least cleft at the tip. In Barinus the last tarsal segment has two claws though these are very closely connate to near the tip in some species. In Barinus robustus (Blatchley) and Barinus productum (Casey) this character is a little difficult to see but careful examination will show that the claws are actually connate to very near tip. There are no basic differences in either the male or female genitalia. The author is indebted to the persons and institutions which made material available for study. The author is particularly indebted to Miss Rose E. Warner of the United States National Museum, Dr. Milton W. Sanderson of the Illinois State Natural History Survey and Dr. J. J. Davis who made arrangements which allowed the author to examine material in the Blatchley Collection at Purdue University.

  • Conspicuousness, Phylogenetic Structure, and Origins of Müllerian
    www.nature.com/scientificreports OPEN Conspicuousness, phylogenetic structure, and origins of Müllerian mimicry in 4000 lycid beetles from all zoogeographic regions Michal Motyka1, Dominik Kusy1, Michal Masek1, Matej Bocek1, Yun Li1, R. Bilkova1, Josef Kapitán2, Takashi Yagi3 & Ladislav Bocak1* Biologists have reported on the chemical defences and the phenetic similarity of net-winged beetles (Coleoptera: Lycidae) and their co-mimics. Nevertheless, our knowledge has remained fragmental, and the evolution of mimetic patterns has not been studied in the phylogenetic context. We illustrate the general appearance of ~ 600 lycid species and ~ 200 co-mimics and their distribution. Further, we assemble the phylogeny using the transcriptomic backbone and ~ 570 species. Using phylogenetic information, we closely scrutinise the relationships among aposematically coloured species, the worldwide diversity, and the distribution of aposematic patterns. The emitted visual signals difer in conspicuousness. The uniform coloured dorsum is ancestral and was followed by the evolution of bicoloured forms. The mottled patterns, i.e. fasciate, striate, punctate, and reticulate, originated later in the course of evolution. The highest number of sympatrically occurring patterns was recovered in New Guinea and the Andean mountain ecosystems (the areas of the highest abundance), and in continental South East Asia (an area of moderate abundance but high in phylogenetic diversity). Consequently, a large number of co-existing aposematic patterns in a single region and/or locality is the rule, in contrast with the theoretical prediction, and predators do not face a simple model-like choice but cope with complex mimetic communities. Lycids display an ancestral aposematic signal even though they sympatrically occur with diferently coloured unproftable relatives.

  • Colonization of Artificially Stressed Black Walnut Trees by Ambrosia Beetle, Bark Beetle, and Other Weevil Species (Coleoptera: Curculionidae) in Indiana and Missouri
    COMMUNITY AND ECOSYSTEM ECOLOGY Colonization of Artificially Stressed Black Walnut Trees by Ambrosia Beetle, Bark Beetle, and Other Weevil Species (Coleoptera: Curculionidae) in Indiana and Missouri 1,2 3 1 4 SHARON E. REED, JENNIFER JUZWIK, JAMES T. ENGLISH, AND MATTHEW D. GINZEL Environ. Entomol. 44(6): 1455–1464 (2015); DOI: 10.1093/ee/nvv126 ABSTRACT Thousand cankers disease (TCD) is a new disease of black walnut (Juglans nigra L.) in the eastern United States. The disease is caused by the interaction of the aggressive bark beetle Pityophthorus juglandis Blackman and the canker-forming fungus, Geosmithia morbida M. Kolarik, E. Freeland, C. Utley & Tisserat, carried by the beetle. Other insects also colonize TCD-symptomatic trees and may also carry pathogens. A trap tree survey was conducted in Indiana and Missouri to characterize the assemblage of ambrosia beetles, bark beetles, and other weevils attracted to the main stems and crowns of stressed black walnut. More than 100 trees were girdled and treated with glyphosate (Riverdale Razor Pro, Burr Ridge, Illinois) at 27 locations. Nearly 17,000 insects were collected from logs harvested from girdled walnut trees. These insects represented 15 ambrosia beetle, four bark beetle, and seven other weevil species. The most abundant species included Xyleborinus saxeseni Ratzburg, Xylosandrus crassiusculus Motschulsky, Xylosandrus germanus Blandford, Xyleborus affinis Eichhoff, and Stenomimus pallidus Boheman. These species differed in their association with the stems or crowns of stressed trees. Multiple species of insects were collected from individual trees and likely colonized tissues near each other. At least three of the abundant species found (S. pallidus, X.

Twenty-three species documented from the parkway are first records for the state. Of the nine capture methods used during the survey, Malaise traps were the most successful. Periods of adult activity, based on dates of capture, are given for each species. Relative abundance is noted for each species based on the number of captures. Sixteen species adventive to North America are documented from the parkway, including three species documented for the first time in the state. Range extensions are documented for two species. Images of five species new to Virginia are provided. Keywords: beetles, biodiversity, Malaise traps, national parks, new state records, Potomac Gorge.

  • Coleoptera: Curculionidae)
    Systematics, Morphology, and Evolution of the New World Conoderinae Schoenherr, 1833 (Coleoptera: Curculionidae) by Salvatore Anzaldo A Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy Approved June 2019 by the Graduate Supervisory Committee: Nico Franz, Chair Emilia Martins Kathleen Pigg Christian Rabeling ARIZONA STATE UNIVERSITY December 2019 ABSTRACT Weevils are one of the most diverse groups of animals with thousands of species suspected to remain undiscovered. The Conoderinae Schoenherr, 1833 are no exception, being especially diverse and unknown in the Neotropics where they are recognizable for their unique behaviors and color patterns among weevils. Despite these peculiarities, the group has received little attention from researchers in the past century, with almost nothing known about their evolution. This dissertation presents a series of three studies that begin to elucidate the evolutionary history of these bizarre and fascinating weevils, commencing with an overview of their biology and classificatory history (Chapter 1). Chapter 2 presents the first formal cladistic analysis on the group to redefine the New World tribes Lechriopini Lacordaire, 1865 and Zygopini, Lacordaire, 1865. An analysis of 75 taxa (65 ingroup) with 75 morphological characters yielded six equally parsimonious trees and synapomorphies that are used to reconstitute the tribes, resulting in the transfer of sixteen genera from the Zygopini to the Lechriopini and four generic transfers out of the Lechriopini to elsewhere in the Conoderinae. Chapter 3 constitutes a taxonomic revision of the genus Trichodocerus Chevrolat, 1879, the sole genus in the tribe Trichodocerini Champion, 1906, which has had an uncertain phylogenetic placement in the Curculionidae but has most recently been treated in the Conoderinae.
