Phylogeny Of Family Limnephilidae (Insecta: Trichoptera) With Emphasis On Tribe Limnephilini (Subfamily Limnephilinae), Tatyana Vshivkova Apr 2014

Phylogeny Of Family Limnephilidae (Insecta: Trichoptera) With Emphasis On Tribe Limnephilini (Subfamily Limnephilinae), Tatyana Vshivkova

John C Morse

Morphological characters of adults and immature stages of Limnephilidae were analyzed with modern phylogenetic techniques, including traditionally used characters and some that have been poorly investigated or never studied. For the first time, monophyly is inferred for the following nominotypical taxa: superfamily Limnephiloidea, family Limnephilidae, subfamily Limnephilinae, tribe Limnephilini, and Limnephilus sensu stricto. Some other higher taxa are distinguished based on high bootstrap support, unreversed synapomorphies, and/or topography, including a new family-group category for Trichoptera, 'Branch,' more inclusive than the family category and less inclusive than the superfamily category. These new taxa in Limnephiloidea are as follows: Brachycentrida New Branch …


A Morphological And Genetic Analysis Of Forensically Important Blow Flies, From Georgia: The Genus Lucilia, Katie S. Googe Apr 2014

A Morphological And Genetic Analysis Of Forensically Important Blow Flies, From Georgia: The Genus Lucilia, Katie S. Googe

Honors College Theses

Identification of Blow flies (Diptera: Calliphoridae) to species is important for estimating postmortem intervals, because insect species develop at different rates. Three Blow fly species in Georgia; Lucilia coeruleiviridis, L. cuprina, and L. sericata are similar morphologically, making identification difficult. Furthermore, the status of L. cuprina is in doubt; this species may be a complex of true L. cuprina, and L. cuprina x L. sericata hybrids. The objective of this study was to survey the Georgia Blow fly community and validate the statuses of L. coeruleiviridis, L. cuprina, and L. sericata, through morphological and …


A Revision And Phylogenetic Analysis Of The Genus Eutyphlus Leconte (Coleoptera: Staphylinidae: Pselaphinae) With A Comparison Of Sampling Methodologies, Brittany Elin Owens Jan 2014

A Revision And Phylogenetic Analysis Of The Genus Eutyphlus Leconte (Coleoptera: Staphylinidae: Pselaphinae) With A Comparison Of Sampling Methodologies, Brittany Elin Owens

LSU Master's Theses

My thesis research includes three components: (1) a methodology project, (2) a systematic project comprising a taxonomic revision, and (3) a morphology-based, cladistic analysis. 1. The methodological study compared the Winkler (Moczarski) eclector and the Berlese-Tullgren funnel (referred to hereafter as “Winkler” and “Berlese” funnels, respectively) as methods for extracting forest litter-dwelling Coleoptera from sifted substrate, with a focus on relevance for taxonomic studies. A general review of the history and methodologies of leaf litter arthropod extraction was provided, in conjunction with repeated, timed trials to compare the relative effectiveness of the two methods using litter samples from various geographic …
