Euscorpius
We address the taxonomic position of Orthodactylus olivaceus Karsch, 1881, the type species of the genus Orthochirus Karsch, 1892. For over a century, this taxon was considered a synonym of Orthochirus scrobiculosus (Grube, 1873); however, the latter was recently limited to Central Asia (Turkmenistan) (Kovařík et al., 2020). Analysis of Karsch’s holotype confirmed that Orthochirus olivaceus (Karsch, 1881), is a valid species. Its type locality published as “Sicily” is clearly incorrect. It is a senior synonym of Butheolus aristidis Simon, 1882, syn. n., described from Sudan (Nubia). We confirm its distribution in northern Sudan and southern Egypt.

Analysis Of Genomic Sequence Data Reveals The Origin And Evolutionary Separation Of Hawaiian Hoary Bat Populations, Corinna A. Pinzari, Lin Kang, Pawel Michalak, Lars S. Jermiin, Donald K. Price, Frank J. Bonaccorso
Life Sciences Faculty Research
We examine the genetic history and population status of Hawaiian hoary bats (Lasiurus semotus), the most isolated bats on Earth, and their relationship to northern hoary bats (Lasiurus cinereus), through whole-genome analysis of single-nucleotide polymorphisms mapped to a de novo-assembled reference genome. Profiles of genomic diversity and divergence indicate that Hawaiian hoary bats are distinct from northern hoary bats, and form a monophyletic group, indicating a single ancestral colonization event 1.34 Ma, followed by substantial divergence between islands beginning 0.51 Ma. Phylogenetic analysis indicates Maui is central to the radiation across the archipelago, with the southward expansion to Hawai‘i and …

We describe six new species of Orthochirus: O. birulai sp. n. (Pakistan), O. formozovi sp. n. (Afghanistan, Iran, Tajikistan, Turkmenistan), O. grosseri sp. n. (Uzbekistan), O. kryzhanovskyi sp. n. (Pakistan), O. nordmanni sp. n. (Afghanistan), and O. sejnai sp. n. (Iran). Descriptions are complemented with color photographs of preserved specimens. The identities of Orthochirus melanurus (Kessler, 1874) (Kazakhstan, Uzbekistan), O. persa (Birula, 1900), stat. n. (Afghanistan, Iran), and O. scrobiculosus (Grube, 1873) (Turkmenistan) are reexamined, based on detailed study of the type specimens; lectotypes of all three species are designated. We demonstrate for the first time that the name …

Euscorpius
A male of Wernerius mumai (Sissom, 1993) is described for the first time, collected at the type locality (Gold Road, Black Mountains, Mohave County, Arizona). Originally placed in the genus Vaejovis, this species later was transferred by Soleglad & Fet (2008) to the genus Wernerius. It is one of the smallest vaejovid species known. The pedipalp fixed finger usually has 6 ID denticles and the movable finger has 7. The most unique characteristic of this species is the long, pointed, subaculear tubercle.

Integrative Species Delimitation And Taxonomic Status Of The Scorpion Genus Vaejovis Koch, 1836 (Vaejovidae) In The Santa Catalina Mountains, Arizona, Emma E. Jochim, Lillian-Lee M. Broussard, Brent E. Hendrixson
Euscorpius
Scorpions belonging to the Vaejovis vorhiesi species complex are widely distributed throughout the southwestern United States and northern Mexico. Most species are endemic to single mountain ranges but two species, Vaejovis deboerae Ayrey, 2009 and V. brysoni Ayrey & Webber, 2013, have been documented from the Santa Catalina Mountains in Arizona. We reevaluated the taxonomic diversity of these scorpions by integrating data from several different sources. Phylogenetic analyses indicate that scorpions in the Santa Catalina Mountains are monophyletic but comprise two divergent mitochondrial lineages that overlap at the type locality of V. deboerae. We failed to detect congruence between …

Structure And Evolution Of Lizard Immunity Genes, Trent Santonastaso
LSU New Orleans Theses and Dissertations
One of the most important gene families to play a role in adaptive immunity is the major histocompatibility complex (MHC). MHC class II loci are considered to be the most variable loci in the vertebrate genome, and studies have shown that this variability can be maintained through complex co-evolutionary dynamics between host and parasite. Despite the rich body of research into the MHC, there is comparatively little understanding of its genomic architecture in reptiles. Similarly, loci associated with innate immunity have received little attention in reptiles compared to other vertebrates. In the first chapter, we investigated the structure and organization …

Hind Wing Eyespots Of Brassolini Butterflies (Lepidoptera, Nymphalidae): Evolutionary Diversification And Functions In Anti-Predator Defense And Mating Behavior, Logan Crees
LSU New Orleans Theses and Dissertations
Ventral hind wing eyespots are prominent pattern elements in Brassolini butterflies, likely functioning in predator-prey interactions and reproductive activities. Caligo and Opsiphanes differ in male mate-seeking behaviors and it has been suggested that Caligo females use the male cua1 eyespot as a mate-locating cue, but Opsiphanes females do not seem to do so. We predict Caligo males should have larger eyespots than congeneric females, but the sexes would not differ in eyespot size in Opsiphanes. Our analyses supported both these predictions. Displacing the eyespot to the center of the wing makes eyespots more conspicuous, we asked if eyespot position …

Interrelationships Among Monorchiid Trematodes With Special Emphasis On Some Northwestern Atlantic Genera, Apryle Panyi
Master's Theses
The Monorchiidae Odhner, 1911 is a cosmopolitan family of flukes (Trematoda: Digenea) comprising species that parasitize the digestive tract of estuarine and marine fishes as adults. Compared with other oceans, recent morphological or molecular taxonomic work conducted on monorchiid species from the northwestern Atlantic Ocean has been sparse (Manter, 1931; Overstreet, 1969; Andres et al., 2018; Wee et al., 2018, 2019, 2020). Therefore, the present work investigated the interrelationships of some monorchiids from the northwestern Atlantic Ocean with emphasis on several genera and investigated if Lasiotocus minutus (Manter, 1931) Thomas, 1959 constitutes a complex of cryptic species. New morphological and …

Consider The Agent In The Arthropod, Nicolas Delon, Peter Cook, Gordon Bauer, Heidi Harley
Animal Sentience
Whether or not arthropods are sentient, they can have moral standing. Appeals to sentience are not necessary and retard progress in human treatment of other species, including invertebrates. Other increasingly well-documented aspects of invertebrate minds are pertinent to their welfare. Even if arthropods are not sentient, they can be agents whose goals—and therefore interests—can be frustrated. This kind of agency is sufficient for moral status and requires that we consider their welfare.

Five New Species Of Euscorpius Thorell, 1876 (Scorpiones: Euscorpiidae) From Albania, Greece, North Macedonia, And Serbia, František Kovařík, František Šťáhlavský
Euscorpius
Five new species are described: Euscorpius bonacinai sp. n. (Albania), E. janstai sp. n. (North Macedonia), E. kabateki sp. n. (Greece), E. sadileki sp. n. (Serbia), and E. scheraboni sp. n. (Greece), fully complemented with color photographs. New species are distinguished from all other species of the genus on the basis of five taxonomic characters. Two other new characters, shape of the pedipalp chela fingers and number of chromosomes, are presented and discussed. In addition to the analyses of external morphology, we also describe karyotypes of two species: E. janstai sp. n. (2n=112) and E. sadileki sp. n. (2n=90).

Do Beetles Have Experiences? How Can We Tell?, Matt Cartmill
Animal Sentience
We attribute consciousness to other humans because their anatomy and behavior resembles our own and their verbal descriptions of subjective experiences correspond to ours. Nonhuman mammals have somewhat humanlike behavior and anatomy, but without the verbal descriptions. Their sentience is therefore open to Cartesian doubt. Robot "minds" lack humanlike behavior and anatomy, and so their sentience is generally discounted no matter what sentences they generate. Invertebrates lack both neurological similarity and language. Although it may be safest in making moral judgments to assume that some invertebrates are sentient, cogent reasons for thinking so must await an objective causal explanation for …

Avoiding Anthropocentrism In Evolutionarily Inclusive Ethics, Simon Fitzpatrick
Animal Sentience
Mikhalevich & Powell are to be commended for challenging the “invertebrate dogma” that invertebrates are unworthy of ethical concern. However, developing an evolutionarily inclusive ethics requires facing some of the more radical implications of rejecting hierarchical scala naturae and human-centered conceptions of the biological world. In particular, we need to question the anthropocentric assumptions that still linger in discussions like these.

My commentary focusses on Mikhalevich & Powell’s criticisms of the Animal Sentience Precautionary Principle. I emphasize the pragmatic nature of my rationale for proposing that, rather than extending the scope of animal welfare protection on a species-by-species basis, we should be willing to protect entire Linnaean orders on the basis of evidence from a single species.

Brain Complexity, Sentience And Welfare, Donald M. Broom
Animal Sentience
Neither sentience nor moral standing is confined to animals with large or human-like brains. Invertebrates deserve moral consideration. Definition of terms clarifies the relationship between sentience and welfare. All animals have welfare but humans give more protection to sentient animals. Humans should be less human-centred.

Animal Sentience
All animal species have adapted for survival and no species is superior overall. For cognitive capacities and sentience, invertebrates such as the octopus, although quite unlike vertebrates, can achieve similar performance levels. So can other invertebrates with small brains; hence they too, as sentient beings, deserve moral consideration from humans. How are we to identify these species? Only though a detailed analysis of their behavior. The decision, which is a moral judgment, depends on biological knowledge that still needs to be acquired.

Convergent Evolution Of Sentience?, Culum Brown Prof.
Animal Sentience
Mikhalevich & Powell make a compelling case that some invertebrates may be sentient and that our moral obligations in the context of welfare should hence extend to them. Although the case is similar to that made for fishes, there is one obvious difference in that examples of invertebrate sentience probably arose independently from vertebrate sentience. We have unequivocal proof that complex cognition arose multiple times over evolutionary history. Given that cognition is our best tool for indirectly quantifying sentience, it seems highly likely that this multiple polygenesis may also have occurred for sentience. In acknowledging this, we must accept that …

Notes On The Diet And Reproduction Of The Bark Scorpion Centruroides Gracilis (Scorpiones: Buthidae) On Utila Island, Honduras, Anna M. Davison, Tom W. Brown, Cristina Arrivillaga
Euscorpius
The brown bark scorpion Centruroides gracilis (Latreille, 1804) (Buthidae) is an abundant and widespread species, however, fairly little is known about its ecology and natural history. We include several observations from Utila Island, Honduras, that expand on the known literature regarding the diet and reproductive behavior of C. gracilis. We report several prey items for this opportunistic species, which include invertebrates such as spiders (including tarantulas), centipedes, katydids, and crickets; as well as a case of cannibalism between two adult females C. gracilis. We suggest that such cannibalism may be driven by high population densities and/or strong intraspecific …

Minds, Morality And Midgies, Brian Key, Deborah Brown
Animal Sentience
Mikhalevich & Powell argue that the exclusion of the vast majority of arthropods from moral standing is unwarranted, particularly given the purported evidence for cognition and sentience in these organisms. The implied association between consciousness and moral standing is questionable and their assumption that rich forms of cognition and flexible behavior are dependent on phenomenal consciousness needs to be reconsidered in light of current neuroscientific evidence. We conclude by proposing a neural algorithmic approach for deciphering whether organisms are capable of subjective experience.

A new species of the diplocentrid scorpion of the genus Didymocentrus Kraepelin, 1905 is herein described from the Lesser Antillean island of Martinique. It long remained misidentified as Didymocentrus lesueurii (Gervais, 1844), the only species of this genus inhabiting the adjacent island of Saint Lucia. The direct comparison of adults of both sexes from these two islands revealed solid morphological characters, which warrant their recognition as two different taxa. Each one is endemic from a single major island, where it is widespread even in its satellite islets. This addition raises the known composition of the genus to 12 species, 10 …
