Redescription Of Centruroides Granosus (Thorell, 1876) And Identity Of Centrurus Granosus Simplex Thorell, 1876 (Scorpiones: Buthidae), Luis F. De Armas, Rolando Teruel, František Kovařík

Euscorpius

Centruroides granosus (Thorell, 1876) is redescribed based on several specimens of both sexes from Panama. We demonstrate that the original description of this species was based on an immature (subadult) male, which is herein designated as the lectotype. We conclude that Centrurus granosus simplex Thorell, 1876 is a senior synonym of Centruroides testaceus arubensis (Bakker, 1963), and elevate it to species level: Centruroides simplex (Thorell, 1876), comb. nov.

Hemiscorpius Novaki Sp. N. From Somaliland (Scorpiones: Hemiscorpiidae), František Kovařík, Tomáš Mazuch

Euscorpius

Hemiscorpius novaki sp. n. from Somaliland is described and compared with other African species of the genus. The new species is characterized chiefly by the total length of 40–46 mm; yellow to yellowish-brown color with pedipalp fingers reddish brown to black, darker than the chela; slightly longer metasoma in the male than in the female. These characters distinguish H. novaki sp. n. from H. somalicus Lourenço, 2011. The third African species of the genus, H. tellinii Borelli, 1904, is known only from the female holotype, which differs from females of H. novaki sp. n. in having much less pronounced granulation …

Pectine Development In Scorpion Embryos And First And Second Instars, Roger D. Farley

Euscorpius

The pectines are complex sensory organs that extend from the ventral surface of the anterior opisthosoma (mesosoma) in all extant scorpions and nearly all the fossil scorpions that have been examined. The pectines are synapomorphic for the Order Scorpiones. In this investigation, the scanning electron microscope (SEM) was used to study the development of the pectines in representatives from five scorpion families. In the more basal families (e.g., Vaejovidae) with apoikogenic development, the pectines start to develop early with enlargement of the limb buds on the third opisthosomal segment. The primordial pectines become elongate lobes attached to the ventro-lateral surface …

In Situ Infrared Videography Of Sand Scorpion Nighttime Surface Activity, Douglas D. Gaffin

Euscorpius

Sand scorpions make burrows from which they emerge at night to seek mates and prey. Previous ecological studies have documented scorpion activities on the sand surface. Few studies, however, have videotaped scorpion movements in the context of understanding their sensory neurobiology. Our objective is to understand which signals guide scorpions as they emerge from and return to their burrows. Candidate stimuli include chemical trails, footsteps, celestial patterns, geomagnetic cues, humidity and/or temperature gradients, distinctive scents from the burrow, seismic echolocation, memory, or landmark orientation. We videotaped scorpions to learn whether they return to their burrows by the same path they …

Polymorphism And Hybridization In Species Of Hottentotta Birula, 1908 (Scorpiones: Buthidae), Wilson R. Lourenço, Eric Ythier, Mark Stockmann, John L. Cloudsley-Thompson

Euscorpius

A new and well documented case of hybridization among scorpions is presented. It was obtained under laboratory conditions between Hottentotta jayakari (Pocock) and Hottentotta salei (Vachon) specimens of which had been collected in the northern and southern regions of Oman. Hybrids were successfully produced not only from F₀males and females, but also from F₁males and females, thereby attesting to the fact that the first generation obtained (F₁), was completely fertile. Both F₁and F₂broods were composed of dark and pale morphs, indicating that the juveniles could inherit either one or …

Scorpions In The Modern Cuban Culture: An Introductory Iconography, Luis F. De Armas

Euscorpius

Some graphic examples of the role of scorpions in the present-day culture of Cuba are presented. They include tattoos, jewels, carpets, caps, and drawings by children, among other objects of personal or social usage. Increased use of this arachnid as a cultural element among Cuban people during last 50 years seems to be directly related with globalization, mostly through the TV and movies.

On Fabre’S Traces: An Important Contributor To The Knowledge Of Buthus Occitanus (Amoreux, 1789), Marco Colombo

Euscorpius

Jean-Henri Casimir Fabre (1823–1915) has probably been one of the most important entomologists of the world in the last two centuries, leaving to posterity a huge amount of manuscripts and books. The Languedoc yellow scorpion, Buthus occitanus (Amoreaux, 1789), has been one of his objects of study: many of its behaviours, including the famous “promenade a deux”, have been described by the careful eye of the French entomologist, giving an interesting contribution to modern scorpiology

The First Record Of Upper Permian And Lower Triassic Scorpions From Russia (Chelicerata: Scorpiones), Victor Fet, Dmitry E. Shcherbakov, Michael E. Soleglad

Euscorpius

Several small fragments of fossil scorpions are reported from two localities in Vologda Province, Russia, representing the Upper Permian (Severodvinian, correlated to Wuchiapingian) (Isady) and Lower Triassic just above the Permian-Triassic boundary (Induan) (Nedubrovo). Most observed structures are not diagnostic at genus or family level. The Isady leg fragment possesses ungues (claws), which are both denticulated and setaceous, and resembles a Carboniferous Eobuthus sp. (Eobuthidae). It is the latest record of this type of ungues, which are known in some Paleozoic scorpions (extinct suborder Mesoscorpiones); all extant scorpions have smooth claws without denticulation or setation.

Further Considerations On The Species Of The Genus Orthochirus Karsch, 1891 From Africa, With Description Of Three New Species (Scorpiones: Buthidae), Wilson R. Lourenço, Elise-Anne Leguin

Euscorpius

New considerations are proposed regarding the African species of the genus Orthochirus Karsch, 1891. Two species, Orthochirus aristidis (Simon, 1882) and Orthochirus innesi Simon, 1910 have been the subject of several publications in the past decades; however, doubts remain about their exact identity and range of geographical distribution. In this note, their taxonomic status is reinvestigated. The type material is revised and the lectotype and paralectotypes are designated for O. aristidis. Revised diagnoses and illustrations are proposed for both species, and these are confirmed as valid. Three new species are described from Algeria, Morocco, and Mauritania. The total number …

Scorpions In Ancient Egypt, Hisham K. El-Hennawy

Euscorpius

The ancient Egyptians knew the scorpion and its toxicity, and venerated it since pre-dynastic era. They used the scorpion as a king's name, a name of a nome (county), and a symbol to their goddess, Serqet, that protects the body and the viscera of the dead, and that accompanies them in their journey to the afterlife. They had medical prescriptions and magical spells to heal the stings. Since the 5th dynasty, the title of a “Follower of Serket” was given to clever physicians. Scorpions are most famously depicted on Horus Cippus, a talisman featuring Horus the Child holding in his …

Historical Diversification Of Montane Herpetofauna Within And Between The Sierras Of Mexico, Robert William Bryson Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Mexican highlands consist of four major mountain ranges spanning most of mainland Mexico. The evolutionary history of the Mexican highlands has been shaped by various geological and climatic events over the past several million years. The relative impacts of these historical events on diversification in montane taxa, however, remains uncertain. I used mitochondrial DNA data from three widely distributed species complexes of lizards as a model system to exemplify the potential roles of Neogene mountain formation and Quaternary climate change on timing and tempo of diversification across the Mexican highlands. My results suggested strong geographic partitioning of genetic variation …

A Taxonomic Revision Of The New World Hypoponera Santschi, 1938 (Hymenoptera: Formicidae), Shawn Thomas Dash

Open Access Theses & Dissertations

The New World taxa of the pantropic ant genus Hypoponera (Ponerinae: Ponerini) is revised for the first time. The 55 previously recognized taxa have been evaluated using morphological and, when possible, ecological and biogeographical data to resolve taxon validity and species limits. Currently I recognize 42 species of Hypoponera , a number of which are new. I propose the following taxonomic outline: Hypoponera agilis (Borgmeier), Hypoponera aliena (F. Smith), Hypoponera antoniensis (Forel) stat. nov., Hypoponera apateae sp. nov., Hypoponera capilosa sp. nov., Hypoponera clinei sp. nov., Hypoponera clavatula (Emery) [= fiebrigi (Forel) syn. nov., = neglecta (Santschi) syn. nov.], Hypoponera …

Phylogeography Of Northern Populations Of The Black-Tailed Rattlesnake (Crotalus Molossus Baird And Girard, 1853) With The Revalidation Of C. Ornatus Hallowell, 1854, Christopher Anderson

Open Access Theses & Dissertations

The black-tailed rattlesnake (Crotalus molossus Baird and Girard, 1853) is a wide-ranging species complex with representatives from the southwestern United States through the highlands of central and southern Mexico. The systematics of this group has received little attention and in the past six decades only two taxonomic revisions have been proposed (the transfer of C. basiliscus oaxacus to C. molossus and the elevation of C. m. estebanensis to full species). However, a recent revision of the Neotropical rattlesnakes (C. durissus and C. simus) recovered a polyphyletic C. molossus. Sequenced data were obtained from three mitochondrial genes …

Systematics Of The Genus Ptychadena Boulenger, 1917 (Anura: Ptychadenidae) From Democratic Republic Of The Congo, Katrina Marie Weber

Open Access Theses & Dissertations

This thesis increases the scope of previous phylogenetic analyses that revealed high levels of genetic differentiation within the anuran genus Ptychadena. Herein, I increase sampling of Central African populations of Ptychadena by over six times to examine their relationships to other African populations and to search for cryptic species. This study represents the most comprehensive molecular phylogeny of Ptychadena to date. A total of three mitochondrial (12S, 16S, and cyt b) and two nuclear (RAG1 and rhodopsin) genes were sequenced for 67 specimens of Ptychadena. Maximum parsimony, maximum likelihood, and Bayesian analyses were conducted. These analyses revealed …

The Cynipoid Genus Paramblynotus: Revision, Phylogeny, And Historical Biogeography (Hymenoptera, Liopteridae), Zhiwei Liu, Fredrik Ronquist, Goeran Nordlander

Faculty Research & Creative Activity

The genus Paramblynotus is the most species-rich genus of the so-called macrocynipoids, the large cynipoid parasitoids of wood-boring and cone-boring insect larvae. The species range in size from some of the largest to the smallest macrocynipoids, comparable in size to microcynipoids. Paramblynotus members occur on all continents except Europe and Australia, with most species being tropical or subtropical. The biology is poorly known but a few observations indicate that the species are parasitoids of beetle larvae. In this monographic revision of the genus, we present a species-level cladistic analysis based on qualitative and quantitative features of the external morphology. For …

Comparative Taphonomy And Paleoecology Of A Glaciomarine Fauna, Carboniferous (Westphalian- Namurian) La Capilla Fm., Argentina, Rex A. Hanger, Mohutsiwa Gabadirwe

Virginia Journal of Science

The Carboniferous La Capilla Fm. of the Calingasta-Uspallata basin of western Argentina contains a low diversity fauna inhabiting a continental shelf under glacial ice fronts advancing from the east. Distal glaciomarine sediments on these ice-influenced shelves of Gondwana are most commonly interpreted as being deposited under quiet, low-energy conditions. Taphonomic and paleoecologic analysis of a sample of the fauna reveals the following: low species richness, yet comparable equitability to coeval, tropical faunas; low articulation ratios and high pedicle valve dominance for brachiopods; diverse corrasion modes, about half relatively high categories; one hundred percent fracturing of brachiopod shells, with carinate fracture …
