Introduction
I am an independent researcher working on the systematics and taxonomy of fireflies. My area of expertise are the fireflies of the West Indies, but I am currently working on an online catalog for the World fireflies. I am also interested in immature lampyrids and am working on several larval descriptions of New World species.

Article
Full-text available
Since the description of the genus Cheguevaria as incertae sedis (Lampyridae), the placement of these beetles has been uncertain. This study is the first to address the placement of this genus based on a molecular phylogenetic analysis. We used three genes (18S rRNA, rrnl mitochondrial DNA and cox1 mitochondrial DNA) and a maximum likelihood approa...
Article

In this study, we describe a new Lampyridae subfamily, Chespiritoinae new subfamily, its sole genus Chespiritonew genus, and three new species: Chespirito zaragozainew species, Chespirito lloydinew species, and Chespirito ballantyneaenew species from the Neotropical portions of Mexico. Chespirito can be readily separated from all other known Lampyr...
Article
The West Indies represents one of the world's hotspots for beetles in the family Lampyridae and includes many endemic taxa. Nine out of 19 genera and 181 out of 186 species of the currently described firefly taxa present in the West Indies are endemic to the region. The objective of this catalog and bibliography is to generate an exhaustive list of...

Two different species descriptions for Luciola roseicollis by Pic (Coleoptera: Lampyridae) are compared, and a replacement name, Luciola lambkinae Keller and Ballantyne nomen novum, for Luciola roseicollis Pic, 1935 is proposed. In McDermott’s (1966) catalog of the family Lampyridae two citations are listed under the heading Luciola roseicollis Pic...

Emarginata Ballantyne, 2019 (Coleoptera: Lampyridae: Luciolinae), is found to be a junior homonym of the bird genus Emarginata Shelley, 1896 (Avis: Passeriformes: Muscicapidae). The new replacement name Emarginoptyx Ballantyne is provided for the SE Asian genus Emarginata Ballantyne, leading to one new combination, Emarginoptyx trilucida (Jeng, Yan...

Haroldiellus woodruffi Skelley and Keller, new species, (Coleoptera: Scarabaeidae: Aphodiinae: Aphodiini), from Costa Rica, Guatemala, Mexico, and Panama is described. An updated key for the genus, updated distributions, and diagnoses for the other two species are provided. Se describe la nueva especie Haroldiellus woodruffi Skelley y Keller (Coleo...

Glaresis franki Keller and Skelley new species and Glaresis thomasi Keller and Skelley new species (Coleoptera: Scarabaeoidea: Glaresidae) are described and illustrated. They represent the first record of the family for the West Indies. Both species are placed into the phoenicis species group. A key to the two West Indies species is presented. Se...

The yellow-legged hornet, Vespa velutina (Lepeletier), is a pest of concern outside of its native range. Vespa velutina is native to Southeast Asia and has invaded several regions in Europe, first appearing in France in 2004. As a generalist predator, they are a pest of honey bees and a major concern to many beekeepers. Vespa velutina has not been...
Article
Clambus formosanus japonicus Endrödy-Younga is reported as a new country record for the USA. Specimens were collected in Mecklenburg County, North Carolina by processing decaying grass clippings with a litter reducer followed by Winkler or Berlese funnel extraction. Specimens were also collected in Union County, North Carolina using a UV light trap...
Article
The Florida State Collection of Arthropods (FSCA) ranks in the top 10 largest Coleoptera collections in the United States of America with in excess of 1.5 million pinned beetles and significant amounts of materials in bulk collections and other unprocessed samples. The suborder Adephaga currently comprises approximately 34,000 species in 10 extant...

Research Highlights: Our study adds to the scant literature on the effects of forest bioenergy on ground beetles (Coleoptera: Carabidae) and contributes new insights into the responses of ground beetle species and functional groups to operational harvest residue retention. We discovered that count of Harpalus pensylvanicus (DeGeer)-a habitat genera...

Notaepytus quisqueya sp. nov. (Erotylidae: Erotylinae: Tritomini), is described here from Dominican amber and is the second amber fossil description for the family from the West Indies (Hispaniola). An emended key and a checklist to all known species of Notaepytus are presented. Key words: Cucujoidea, Greater Antilles, fossil, checklist, key, Mioce...

Insects are possibly the most taxonomically and ecologically diverse class of multicellular organisms on Earth. Consequently, they provide nearly unlimited opportunities to develop and test ecological and evolutionary hypotheses. Currently, however, large-scale studies of insect ecology, behavior, and trait evolution are impeded by the difficulty i...
Technical Report
The giant black water beetle (Hydrophilus triangularis) is the largest aquatic-dwelling beetle in not only Florida, but in the entire United States (Epler 2010). Commonly seen across the continental US, this beetle has the widest distribution in the genus Hydrophilus (Short and McIntosh 2014). This beetle needs fresh water to reproduce, and prefers...

Ants (Formicidae: Hymenoptera) are important components of forest ecosystems and can be affected by fuel reduction forest management practices. We assessed the impact of repeated applications of fuel reduction treatments on abundance and diversity of ants within upland mixed-hardwood forests in the Southern Appalachian Mountains in North Carolina,...

The following nomenclatural changes for several firefly taxa (Coleoptera: Lampyridae) are proposed and herein implemented. Correction of authorship is proposed for Lampyroidea lucifer (Reiche and de Saulcy, 1857). Spelling corrections are proposed for Photinus coroicosus Pic, 1941 and Macrolampis flavithorax Pic, 1940. Dates of publication are corr...

The Hercules beetle, Dynastes hercules (Linnaeus), is a dynastine scarab beetle in the family Scarabaeidae. Some of the more recognizable beetles in the subfamily Dynastinae have males that possess thoracic and/or cephalic horns. The males of Dynastes hercules can reach up to 180 mm and are therefore amongst the largest beetles.

Determining the distribution of infectious disease agents such as Batrachochytrium dendrobatidis (Bd), the pathogenic fungus that causes chytridiomycosis, is important for understanding disease patterns and transmission in populations. In the USA, Bd has been broadly sampled and detected throughout most regions (46 of 50 states; Bd-maps.net; Gaudre...

Distributions and environmental conditions for the western North American Paracotalpa ursina (Scarabaeidae: Rutelinae: Areodina) species complex are assessed using niche modeling. This species complex occurs mainly in the California Floristic Province and includes as many as nine morphotypes. Its high phenotypic variation could be influenced by mec...

The Berlese funnel is an apparatus developed by Antonio Berlese to extract small arthropods from leaf litter, soil, and other organic materials. The basic apparatus is a funnel that contains medium sized wire mesh upon which organic material is placed. Beneath the funnel a vial containing alcohol is attached to catch and preserve the specimens that...
