A New Species Of Kochius From Avra Valley, Southern Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey, Lawrence L. C. Jones, Brandon Myers
Euscorpius
A new scorpion species, Kochius colluvius sp. n. is described (Scorpiones: Vaejovidae). This small brown species is found in the Avra Valley near Tucson, Arizona, USA. It appears to be most similar to Kochius sonorae (Williams, 1971) and K. hirsuticauda (Banks, 1910). On all fingers examined, the fixed finger has 6 ID denticles and the movable finger has 7. There is no scalloping of the chela fingers. This species differs from all other vaejovids in Arizona by having a coarsely granulated exoskeleton.

Systematics Of Carex Section Laxiflorae (Cyperaceae), Jenna Dorey
Dissertations, Theses, and Capstone Projects
Carex, with more than 2100 species, is the most species-rich genus of flowering plants in temperate regions of the world. Members of the family Cyperaceae are colloquially known as sedges, and members of the genus Carex are called “true sedges.” Carex occur on every continent except for Antarctica, they thrive in a panoply of habitats, and are ecologically important as a forage source for wildlife, carbon sequestration, prevention of soil erosion, and providing habitat for fresh water invertebrates. Despite their importance many sedges are still poorly known, such as the woodland sedges in Carex section Laxiflorae, which is …

Euscorpius
A neotype is designated for a very rare Central Asian scorpion, Pectinibuthus birulai Fet, 1984, the sole species of the genus Pectinibuthus Fet, 1984. It is the only currently known specimen, collected by Victor Fet in July 1985, and deposited in ZISP (St. Petersburg, Russia). The original types are considered lost. Detailed photographs of the neotype are provided, as well as comments on this unique psammophile buthid. We also discuss and compare pectinal tooth counts of psammophile scorpions relative to other scorpions.
A New Species Of Catalinia Soleglad Et Al., 2017 (Scorpiones: Vaejovidae) From Southern California, Usa, Rolando Teruel, Brandon Myers
A New Species Of Catalinia Soleglad Et Al., 2017 (Scorpiones: Vaejovidae) From Southern California, Usa, Rolando Teruel, Brandon Myers
Euscorpius
Herein we describe a new species of the vaejovid scorpion genus Catalinia Soleglad, Ayrey, Graham & Fet, 2017. It was collected in a single locality of the northwestern foothills of the Santa Ana Mountains. It is most closely related to both Catalinia andreas (Gertsch & Soleglad, 1972) and C. minima (Kraepelin, 1911), but is clearly distinguished by tegumentary sculpture, morphometric ratios and pectinal tooth counts. The new species is described and illustrated in detail, with some ecological data included; moreover, a minor correction is introduced to the diagnosis of the genus.

Review Of Grosphus Simon, 1880, With Description Of Teruelius Gen. N., A New Buthid Genus From Madagascar (Scorpiones: Buthidae), Graeme Lowe, František Kovařík
Euscorpius
We review the taxonomy of the Madagascar endemic buthid genus Grosphus Simon, 1880. We split the genus and describe Teruelius gen. n. on the basis of nine morphological characters, six of them new for Grosphus: positions of trichobothria d2 on pedipalp femur and Eb3 on chela manus, number of pectine teeth, shape of female basal pectinal tooth, form of hemispermatophore capsule posterior lobe, spiracle shape, metasoma I ventromedian carination, telotarsal setation and UV fluorescence. We discuss functional and taxonomic aspects of these characters, and propose that Teruelius gen. n. is monophyletic, while Grosphus (sensu stricto) is paraphyletic. …

Faculty Journal Articles
The dioecious and andromonoecious Solanum taxa (the “S. dioicum group”) of the Australian Monsoon Tropics have been the subject of phylogenetic and taxonomic study for decades, yet much of their basic biology is still unknown. This is especially true for plant-animal interactions, including the influence of fruit form and calyx morphology on seed dispersal. We combine field/greenhouse observations and specimen-based study with phylogenetic analysis of seven nuclear regions obtained via a microfluidic PCR-based enrichment strategy and high-throughput sequencing, and present the first species-tree hypothesis for the S. dioicum group. Our results suggest that epizoochorous trample burr seed …

A Phylogenetic Analysis Of Bostrichoidea (Coleoptera) And Revisions Of The Southern African Spider Beetle Genera Meziomorphum And Eutaphroptinus (Ptinidae: Coleoptera), Olivia M. Gearner
Masters Theses & Specialist Projects
Proposals for the internal relationships and classification of the bostrichoids are currently poorly supported, and almost all are based on morphology alone. This study improves upon on previous phylogenetic analyses of the group by including more taxa using the standard genes for many phylogenetic analyses. Cytochrome C oxidase subunit 1 (CO1), 28S small subunit rRNA, and 16S small subunit rRNA mitochondrial genes were sequenced or obtained from Genbank, then analyzed using parsimony and Bayesian analyses. Topologies differed depending on genes used. A three gene tree and a two gene (28S and CO1) tree both supported relationships in which a basal …

A New Semidesert Microtityus Kjellesvig-Waering, 1966 (Scorpiones: Buthidae) From Southeast Cuba, Greater Antilles., Rolando Teruel
Euscorpius
A new species of the buthid scorpion genus Microtityus Kjellesvig-Waering, 1966, is herein described from specimens of both sexes collected at three nearby localities in the western part of the Guantánamo Bay Area, southeast Cuba. It belongs in the "jaumei" species-group of the subgenus Microtityus (Parvabsonus) Armas, 1974 and is very peculiar not only by its external morphology (very distinct from its other Cuban congeners), but also by the unusual habitat where it occurs in and seems to be restricted to (dry and hot cactus scrub on volcanic sandy plain). The present contribution reinforces the position of this genus as …

Trade-Offs Shape Carotenoid-Based Color Variation In Redheaded Pine Sawfly (Neodiprion Lecontei) Larvae, Maranda Gaines
Trade-Offs Shape Carotenoid-Based Color Variation In Redheaded Pine Sawfly (Neodiprion Lecontei) Larvae, Maranda Gaines
Lewis Honors College Capstone Collection
Carotenoids serve various ecological roles in animals including coloration, immune responses, and vision. Carotenoid-derived coloration is greatly emphasized in the literature, particularly relating to mate choice and aposematic warning. However, the trade-offs between the color and non-color functions of carotenoids are not thoroughly explored. In the redheaded pine sawfly (Neodiprion lecontei), some larval populations have yellow pigmentation, using carotenoids derived from their diets for aposematic warning coloration. Other larval populations are white in color, having genetically lost the ability to produce the yellow pigment. Because carotenoids are essential to life functions in both the yellow and white populations, we aim …

Chiasmocleis is the most species-rich genus of Neotropical microhylids. Herein, we provide the first comprehensive multilocus phylogeny for the genus, including all but 3 of the 34 recognized species and multiple individuals per species. We discuss cryptic speciation, species discovery, patterns of morphological evolution, and provide a historical biogeographic analysis to account for the current distribution of the genus. Diversification of Chiasmocleis from other New World microhylids began during the Eocene, app. 40 mya, in forested areas, and current diversity seems to be a product of recurrent connections between the Atlantic Forest and Amazonia. Small-sized species evolved independently three times …

Animal Sentience
We are failing to protect the biosphere. Novel views of conservation, preservation, and sustainability are surfacing in the wake of consensus about our failures to prevent extinction or slow climate change. We argue that the interests and well-being of non-humans, youth, and future generations of both human and non-human beings (futurity) have too long been ignored in consensus-based, anthropocentric conservation. Consensus-based stakeholder-driven processes disadvantage those absent or without a voice and allow current adult humans and narrow, exploitative interests to dominate decisions about the use of nature over its preservation for futurity of all life. We propose that authentically non-anthropocentric …

This has important consequences for conservation-related policy and practice at all scales: local, regional, and global.

Euscorpius
New information about the taxonomy and distribution of the genus Neobuthus Hirst, 1911 is presented, based on material recently collected mainly from Somaliland, but also Djibouti and Kenya. Emended diagnoses are proposed for N. berberensis Hirst, 1911 and N. ferrugineus (Kraepelin, 1898) sensu stricto. New species described are: N. amoudensis sp. n. from Ethiopia and Somaliland; N. erigavoensis sp. n., N. factorio sp. n., N. gubanensis sp. n., N. maidensis sp. n., and N. montanus sp. n. from Somaliland; and N. kloppersi sp. n. from Kenya. This doubles the number of species in Neobuthus, unearthing a rich diversification …
