First Report Of The Stinkbug Edessa Leucogramma (Perty) (Hemiptera: Heteroptera: Pentatomidae: Edessinae) Attacking Handroanthus Chrysanthus (Jacq.) S.O. Grose (Bignoniaceae), With Descriptions Of The Adult And Immatures And Notes On Associated Fungi And Protozoa, Gonzalo Abril R., Allan H. Smith-Pardo

Insecta Mundi

The stinkbug Edessa leucogramma (Perty) (Hemiptera: Pentatomidae: Edessinae) is reported as a pest of young yellow guayacán trees (Handroanthus chrysanthus (Jacq.) S.O. Grose, Bignoniaceae) in the met­ropolitan area of the Aburra Valley in Antioquia, Colombia (AMVA). We provide a short description of the adult and immature stages and report for the first-time protozoa associated with the digestive system of this species of true bug in addition to information regarding a fungus found associated with Edessa leucogramma in the field.

A New Species Of Epeolus Latreille, 1802 (Hymenoptera: Apidae) From Western North America, Thomas M. Onuferko, Cory S. Sheffield

Insecta Mundi

A new species of Epeolus Latreille, 1802 (Hymenoptera: Apidae)—E. emiliae Onuferko and Shef­field, new species—is described from North America west of the Great Plains. It is morphologically most similar to Epeolus autumnalis Robertson, 1902, a species known exclusively from east of the Rocky Moun­tains. DNA barcode sequences from representatives of E. autumnalis and E. emiliae share a barcode index number (i.e., BIN: BOLD:AAF2361), but the two species exhibit marked and consistent differences in integu­ment coloration and the patterns of pubescence on the metasoma, and their distributional ranges, based on known specimens, show no overlap. This discovery increases …

Redescription Of The Allomyia Renoa (Milne) Female And Association And Description Of The Male And Larva (Trichoptera: Apataniidae), David E. Ruiter, Donald R. Givens, Hiroyuki Nishimoto

Insecta Mundi

Allomyia renoa (Milne, 1935) (Trichoptera: Apataniidae) was described from six females. The male association is verified in this paper. The original type locality information is limited: “Reno, Nev., ‘78, Morrison”. An Allomyia Banks population found at Mount Rose in Washoe County, Nevada, was compared to the A. renoa type material and found to be the conspecific. Figures, descriptions and distribution of male, female, pupal and larval A. renoa are provided.

How To Distinguish The Xestotrachelus Bruner, 1913 (Orthoptera: Romaleidae: Romaleini) From Other Romaleini In South America, With A Report Of The First Record In Minas Gerais, Brazil, Daniela Santos Martins Silva, Marcelo Ribeiro Pereira, Raysa Martins Lima

Insecta Mundi

The present study provides an important contribution to the knowledge of the geographic distribution of Xestotrachelus Bruner, 1913 (Orthoptera: Romaleidae: Romaleini), a monotypic genus comprised of Xestotrachelus robustus (Bruner, 1911) that has a wide geographic distribution in Brazil. Specimens were collected at the Panga Ecological Reserve, Uberlândia, Minas Gerais, in the Brazilian Cerrado. We provide a key to distinguish Xestotrachelus from other genera found in South America.

New Tribal Placement And Review Of Parapucaya Prell And Pucaya Ohaus (Coleoptera, Scarabaeidae, Dynastinae), Aura Paucar-Cabrera, Matthew Robert Moore

Department of Entomology: Faculty Publications

The dynastine scarab genera Parapucaya Prell and Pucaya Ohaus have been historically classified in Pentodontini; however, that tribal classification is not supported under the current tribal circumscriptions. A discussion justifying the transfer of the genera Parapucaya and Pucaya from Pentodontini into Cyclocephalini is presented. This research is based on morphological observations (mandible shape and wing characters among others) and molecular data (genes 28S, COI, and 16S/ND1). A review of both genera is included, providing descriptions, diagnoses, distribution data, illustrations, and keys to species. A revised key to the world genera of Cyclocephalini is also included.

Revision Of The Taxonomic Status Of Aphis Floridanae Tissot (Hemiptera: Aphididae) Using Morphological And Molecular Insight, Doris Lagos-Kutz, Susan E. Halbert, David J. Voegtlin, Glen L. Hartman

Insecta Mundi

Morphological and cytochrome oxidase 1 (Cox1) data show that Aphis floridanae Tissot (Hemiptera: Aphididae) is not synonymous with A. nasturtii Kaltenbach. Instead, A. floridanae matches the morphological characters of A. impatientis Thomas. Additionally, the range of cytochrome oxidase 1 (Cox1) pair-wise distance of the multiple collections of A. impatientis on Cornus spp., Impatiens spp. and Erechtites hieraciifolius (L.) Raf. ex DC. is 0–0.39%. Therefore, we conclude that A. floridanae Tissot, 1933 is a junior synonym of A. impatientis Thomas, 1878, new synonymy. In addition, A. impatientis is re-described, including first descriptions of the ovipara and alate …

Predominantly Left-Dominant Mandibular Chirality In Coleoptera, Mathew L. Brust, W. Wyatt Hoback

Department of Entomology: Faculty Publications

Patterns of mandible chirality have been virtually unexplored in beetles, apart from a single study in 2010. Here we present the mandible chirality trends found in 58 beetle species representing the families Carabidae (52 species), Cerambycidae (three species), and Silphidae (three species) that display overlapping mandibles. Mandible chirality was not random in the groups examined, all of which exhibited a dominant trend towards left-superiority. The degree to which each taxonomic group displayed the left-superior trend differed, with tiger beetles showing the greatest dominance (99%) and longhorned beetles the weakest (71%).

Morphological Characterization And Molecular Mediated Genetic Variation Of Thief Ants (Hymenoptera: Formicidae), Ralph B. Narain, Shripat T. Kamble, Thomas O. Powers

Department of Entomology: Faculty Publications

The morphological characterization and molecular genetic variation were determined in populations of thief ants, Solenopsis molesta (Say). The genetic variations were elucidated using mitochondrial deoxyribonucleic acid (mDNA) sequences of cytochrome oxidase I. DNA from thief ants was extracted with Qiagen’s Gentra PUREGENE DNA Isolation Kit using their solid tissue protocol. Polymerase chain reactions (PCR) were run on the extracted DNA using primers Lep-F1 (forward) and Lep-R1 (reverse). The DNA products were concentrated and purified by Microcon Centrifugal Filter Unit YM-100. Purified DNA samples were sequenced at the University of Arkansas Medical Sciences (UAMS) DNA Sequencing Core Facility. The sequences were …
