Revision Of The Genus Monatractides (Parasitengona, Torrenticolidae) Of The United States And Canada: New Species, Re-Descriptions, Phylogenetics, And A Key To Species, Whitney Anne Nelson Dec 2018

Revision Of The Genus Monatractides (Parasitengona, Torrenticolidae) Of The United States And Canada: New Species, Re-Descriptions, Phylogenetics, And A Key To Species, Whitney Anne Nelson

Graduate Theses and Dissertations

The full suite of known Monatractides (Parasitengona, Torrenticolidae) taxa of North America (north of Mexico) are investigated herein using integrative methods. Species hypotheses are supported with morphology, geography, and phylogenetic analysis of the barcoding region of COI for 154 individuals from over 100 localities. Relationships between species are examined with a combined analysis of COI and 28S rDNA for 55 specimens. Previously described species are examined and re-described with color images and updated information, where possible. Our results indicate the need to synonymize two species: M. californica (Marshall, 1943) is a junior synonym of M. geographica (Marshall, 1943). We describe …


Phylogeny And Population Genetic Analyses Reveals Cryptic Speciation In The Bombus Fervidus Species Complex (Hymenoptera: Apidae), Jonathan B. Koch, Juanita Rodriguez, James P. Pitts, James P. Strange Nov 2018

Phylogeny And Population Genetic Analyses Reveals Cryptic Speciation In The Bombus Fervidus Species Complex (Hymenoptera: Apidae), Jonathan B. Koch, Juanita Rodriguez, James P. Pitts, James P. Strange

Ecology Center Publications

Bumble bees (Bombus Latrielle) are significant pollinators of flowering plants due to their large body size, abundant setae, and generalist foraging strategies. However, shared setal coloration patterns among closely and distantly related bumble bee species makes identification notoriously difficult. The advent of molecular genetic techniques has increased our understanding of bumble bee evolution and taxonomy, and enables effective conservation policy and management. Individuals belonging to the North American Bombus fervidus species-complex (SC) are homogenous in body structure but exhibit significant body color phenotype variation across their geographic distribution. Given the uncertainty of the genealogical boundaries within the SC, some …


Cryptic Diversity In The North American Dromochorus Tiger Beetles (Coleoptera: Carabidae: Cicindelinae): A Congruence-Based Method For Species Discovery, Daniel P. Duran, David P. Herrman, Stephen J. Roman, Rodger A. Gwiazdowski, Jennifer A. Drummond, Glen R. Hood, Scott P. Egan Sep 2018

Cryptic Diversity In The North American Dromochorus Tiger Beetles (Coleoptera: Carabidae: Cicindelinae): A Congruence-Based Method For Species Discovery, Daniel P. Duran, David P. Herrman, Stephen J. Roman, Rodger A. Gwiazdowski, Jennifer A. Drummond, Glen R. Hood, Scott P. Egan

School of Earth & Environment Faculty Scholarship

A fundamental problem in biodiversity science is determining the number of species in any taxon, and there is a growing awareness that cryptic diversity contributes to this problem – even in well-studied groups. Discovering cryptic species requires several lines of evidence to elucidate congruent patterns across data-types, and distinguish unrecognized species. Tiger beetles are among the most well-studied insect groups; yet few new North American species have been described since the mid-20th century, suggesting that that the number of morphologically distinct species is reaching an asymptote. We explore the possibility that more species exist in the fauna as cryptic species, …

Biology Faculty Publications & Presentations

Traditional morphology-based taxonomy of dictyostelids is rejected by molecular phylogeny. A new classification is presented based on monophyletic entities with consistent and strong molecular phylogenetic support and that are, as far as possible, morphologically recognizable. All newly named clades are diagnosed with small subunit ribosomal RNA (18S rRNA) sequence signatures plus morphological synapomorphies where possible. The two major molecular clades are given the rank of order, as Acytosteliales ord. nov. and Dictyosteliales. The two major clades within each of these orders are recognized and given the rank of family as, respectively, Acytosteliaceae and Cavenderiaceae fam. nov. in Acytosteliales, and Dictyosteliaceae …

A New Genus, A New Species, New Combinations, And Notes On Synonymy And Nomenclature In American Desmiphorini (Coleoptera, Cerambycidae, Lamiinae), Antonio Santos-Silva, James E. Wappes

Insecta Mundi

An early, overlooked description of the genus Atelodesmis (Coleoptera, Cerambycidae, Lamiinae) is attributed to Chevrolat (in Duponchel and Chevrolat 1841), with A. mannerheimii Duponchel and Chevrolat, 1841 as its type species, and the genus redescribed. Atelodesmis Buquet, 1857, is a junior synonym and primary homonym of Atelodesmis Chevrolat. Atelodesmis hirticornis Buquet, 1857 and A. vestita Buquet, 1857 are synony­mized with A. mannerheimii. Fallaxdesmis is described as a new genus with Atelodesmis unicolor Buquet, 1857 as type species. Atelodesmis piperita Bates, 1855 is transferred to Eupogonius and newly recorded for the state of Oaxaca, Mexico. A new species for Mexico …


Evaluation Of The Phylogenetic Relationships Of The Marine Rivulariaceae., Jose Alberto Martinez Yerena Jan 2018

Evaluation Of The Phylogenetic Relationships Of The Marine Rivulariaceae., Jose Alberto Martinez Yerena

Masters Theses

Historically, the Rivulariaceae family has grouped all heteropolar, tapered and heterocitous Cyanobacteria, however recent description of multiple cyanobacterial populations with this morphotype using 16S rRNA phylogenies have reported that the populations with this morphotype are polyphyletic, and many new and old tapered and heteropolar genera (Cyanomargarita, Gloeothrichia, Rohoaltiella, etc.) have been classified and reclassified to different families than the Rivulariaceae. This is also the case of the main genera of the family (Rivularia and Calothrix), which have been repeatedly reported as polyphyletic, and whose separation to different families has been called for. In this project I carried out the evaluation …

Generic Changes In The Stag Beetle Tribe Aesalini (Coleoptera: Lucanidae: Aesalinae) With The Description Of Two New Species, M. J. Paulsen

Insecta Mundi

The status of genera and species in the stag beetle tribe Aesalini (Coleoptera: Lucanidae: Aesalinae) is revised. The Asian subgenus Zelenkaesalus Krikken, formerly included within Echinoaesalus Zelenka, is elevated to generic level based on the presence of complete ventral sulci and the form of the ocular canthus. This results in the following new combinations: Z. cechovskyi (Huang et al.), Z. gedeensis (Huang and Wu), Z. javanus (Krikken), Z. sabahensis (Zelenka), and Z. timidus (Krikken). Zelenkaesalus pazuzus Paulsen, new species, is described from the Philippines and is the first record of the subfamily for the country. A new genus Strabaesalus …


Identification Of Taxonomic And Functional Ichthyofaunal Zones Within The James River Basin, Virginia, Joseph L. Noel Jan 2018

Identification Of Taxonomic And Functional Ichthyofaunal Zones Within The James River Basin, Virginia, Joseph L. Noel

Theses and Dissertations

Environmental gradients structure ichthyofaunal communities longitudinally along river networks via the selective filtering of species’ traits. In many instances, these environmental influences have created distinct zones of co-occurring fish species. Zonation studies have most often been conducted with taxonomic data (species x site matrices), but the increasing availability of functional trait data creates an opportunity to build more rigorous understanding of species’ co-occurrence patterns. Notably, zonation studies that use taxonomic data may not reveal the same patterns as studies based on trait data. In this study, we tested for distinct ichthyofaunal zonation in James River Basin, VA using a combination …

Revision Of The Obesus Species Group Of The Stag Beetle Genus Nigidius Macleay (Coleoptera: Lucanidae: Lucaninae: Figulini), M. J. Paulsen Jan 2018

Revision Of The Obesus Species Group Of The Stag Beetle Genus Nigidius Macleay (Coleoptera: Lucanidae: Lucaninae: Figulini), M. J. Paulsen

Insecta Mundi

This paper contains nomenclatural acts concerning the genus Nigidius MacLeay in the stag beetle tribe Figulini Burmeister (Coleoptera: Lucanidae: Lucaninae). A revision of species in the obesus group results in the correction of multiple nomenclatural problems. A lectotype is designated for N. obesus Parry, and the identity of N. helleri Boileau is corrected. A new species, Nigidius gravelyi Paulsen, is described from Borneo. The synonymy of Nigidius larssoni de Lisle is transferred from N. obesus to N. dawnae Gravely.
