Homeowner Guide to Scorpions and Their Relatives
HOMEOWNER Guide to by Edward John Bechinski, Dennis J. Schotzko, and Craig R. Baird CIS 1168 Scorpions and their relatives “Arachnid” is the scientific classification category for all eight-legged relatives of insects. Spiders are the biggest group of arachnids, with nearly 3800 species known from the U.S and Canada. But the arachnid category includes other types of eight-legged creatures that sometime cause concern. Some of Idaho’s non-spider arachnids – such as scorpions -- pose potential threats to human health. Two related non-spider arachnids – sun scorpions and pseudoscorpions – look fearsome but are entirely harmless. This publication will help you identify these three groups and understand the threats they pose. All three of these groups almost always are seen as lone individuals that do not require any control.

Disparate Expression Specificities Coded by a Shared Hox-C Enhancer Steve W Miller*, James W Posakony
RESEARCH COMMUNICATION Disparate expression specificities coded by a shared Hox-C enhancer Steve W Miller*, James W Posakony Division of Biological Sciences, Section of Cell & Developmental Biology, University of California San Diego, La Jolla, United States Abstract Can a single regulatory sequence be shared by two genes undergoing functional divergence? Here we describe a single promiscuous enhancer within the Drosophila Antennapedia Complex, EO053, that directs aspects of the expression of two adjacent genes, pb (a Hox2 ortholog) and zen2 (a divergent Hox3 paralog), with disparate spatial and temporal expression patterns. We were unable to separate the pb-like and zen2-like specificities within EO053, and we identify sequences affecting both expression patterns. Importantly, genomic deletion experiments demonstrate that EO053 cooperates with additional pb- and zen2-specific enhancers to regulate the mRNA expression of both genes. We examine sequence conservation of EO053 within the Schizophora, and show that patterns of synteny between the Hox2 and Hox3 orthologs in Arthropods are consistent with a shared regulatory relationship extending prior to the Hox3/zen divergence. Thus, EO053 represents an example of two genes having evolved disparate outputs while utilizing this shared regulatory region. Editorial note: This article has been through an editorial process in which the authors decide how to respond to the issues raised during peer review. The Reviewing Editor’s assessment is that all the issues have been addressed (see decision letter). Introduction *For correspondence: [email protected] Changes in the expression specificity of genes involved in the development of multicellular organ- isms are implicated in modifications of form and function over evolution (Stern and Orgogozo, Competing interests: The 2008; Wray, 2007; Rebeiz and Tsiantis, 2017; Rubinstein and de Souza, 2013). -

A Global Accounting of Medically Significant Scorpions
Toxicon 151 (2018) 137–155 Contents lists available at ScienceDirect Toxicon journal homepage: www.elsevier.com/locate/toxicon A global accounting of medically significant scorpions: Epidemiology, major toxins, and comparative resources in harmless counterparts T ∗ Micaiah J. Ward , Schyler A. Ellsworth1, Gunnar S. Nystrom1 Department of Biological Science, Florida State University, Tallahassee, FL 32306, USA ARTICLE INFO ABSTRACT Keywords: Scorpions are an ancient and diverse venomous lineage, with over 2200 currently recognized species. Only a Scorpion small fraction of scorpion species are considered harmful to humans, but the often life-threatening symptoms Venom caused by a single sting are significant enough to recognize scorpionism as a global health problem. The con- Scorpionism tinued discovery and classification of new species has led to a steady increase in the number of both harmful and Scorpion envenomation harmless scorpion species. The purpose of this review is to update the global record of medically significant Scorpion distribution scorpion species, assigning each to a recognized sting class based on reported symptoms, and provide the major toxin classes identified in their venoms. We also aim to shed light on the harmless species that, although not a threat to human health, should still be considered medically relevant for their potential in therapeutic devel- opment. Included in our review is discussion of the many contributing factors that may cause error in epide- miological estimations and in the determination of medically significant scorpion species, and we provide suggestions for future scorpion research that will aid in overcoming these errors. 1.

The Scorpion Tityus Macrurus Koch, 1845, Was Described on the Basis of One Male an D One Female from Mexico
Francke, O . F. and F . W. Wagner 1978 . The identity of Tityus macrurus Koch (Arachnida, Scorpionida, Buthidae) . J. Arachnol. 6 :159-160. RESEARCH NOTE THE IDENTITY OF TITYUS MA CR UR US KOCH (ARACHNIDA, SCORPIONIDA, BUTHIDAE ) The scorpion Tityus macrurus Koch, 1845, was described on the basis of one male an d one female from Mexico . At the time this species was described the genus Tityus Koch was poorly characterized, and Koch assigned numerous species to it . Since then, the genus Tityus has been restricted to species found only in South America and southern Centra l America, and T. macrurus has been assigned to the genus Centruroides Marx, foun d mostly in North America, Central America, and the Caribbean islands . The position of the species within this genus, however, has not been clear . While T:horell (1876) indicate d that T. macrurus is a junior synonym of Centrurus biaculeatus (Lucas) [=Centruroides gracilis (Latreille)] and Kraepelin (1899) listed the species as a synonym of C. gracilis, Pocock (1902), Hoffmann (1932), Moreno (1939), and Mello-Leit "o (1945) referred T macrurus to the synonymy of Centruroides margaritatus (Gervais) . Both C. gracilis and C. margaritatus occur in Mexico, and since the placement of T. macrurus within the genu s Centruroides is uncertain, we examined the male type of T. macrurus to determine its identity. The type of Tityus macrurus is definitely a species of the genus Centruroides and is very closely related to the species occurring in coastal Veracruz described and identified by Hoffmann (1932) as C. gracilis. However, as pointed out by one of us (Wagner, 1977), the name Centruroides gracilis is currently applied to a poorly understood complex of species and subspecies from a wide geographic area (Florida and Texas in the USA , Mexico, Central America, the Caribbean Islands, and northern South America to Ecua- dor). -

The Coevolution Between Telson Morphology and Venom Glands in Scorpions (Arachnida)
REVIEW OPEN ACCESS ISSN 1678-9199 www.jvat.org The coevolution between telson morphology and venom glands in scorpions (Arachnida) 1* Wilson R. Lourenço 1Muséum national d’Histoire naturelle, Sorbonne Universités, Institut de Systématique, Evolution, Biodiversité (ISYEB), UMR7205-CNRS, MNHN, UPMC, EPHE, Paris, France. Abstract As in previous contributions to the JVATiTD, the aim of this note is to bring some general information on a particular aspect of the scorpion biology. An attempt is made to explain the possible coevolution of telson morphology and venom glands, which took place during several hundred million years and in particular since scorpions migrated from aquatic to terrestrial environments. Three components can be directly associated with predation and defensive behaviours: (1) morphology of the chelae and structure of the chelae fingers granulations; (2) morphology of the metasoma and in particular of the telson; (3) evolution of tegumentary glands in the telson toward different types Keywords: of venom glands. Since a number of recent contributions already treated some of these Scorpion aspects, I will limit my comments to the possible evolution of the telson in relation to Telson morphology the evolution of venom glands. As in previous contributions, the content of this article is basically addressed to non-specialists on scorpions whose research embraces scorpions Venom glands in several fields such as venom toxins and public health. Coevolution Introduction however, is not precise since scorpions certainly underwent major biochemical, physiological, behavioural and ecological It is well accepted by most authors that scorpions are among adaptations that have combined to ensure their continued success the most ancient and conservative arthropods both in origin over the past 450 million years and in particular their adaptation and body morphology [1,2,3]. -

Cette immense étendue sablonneuse abrite plusieurs faunes désertiques hautement diversifiées. Une étude originale sur la faune scorpionique dans cette région, nous a permis d’inventorier et identifier en totalité huit (08) espèces des scorpions, réparties d’une manière typique selon les différents biotopes naturels (Erg et reg) et biotopes anthropiques (Palmeraies ou oasis et milieux urbains). Une analyse factorielle des correspondances appliquées aux espèces trouvées nous a révélé que l’ Androctonus autralis est l’espèce omniprésente dans tous les biotopes et l’unique espèce qui fréquente les milieux urbains, Androctonus amoreuxi en deuxième place avec une large répartition qui fréquente la majorité des biotopes sauf le milieu urbain. -

Change of Temperature at Sting Site by Scorpion in León, Guanajuato
Research Article Annals of Clinical Toxicology Published: 01 Apr, 2019 Change of Temperature at Sting Site by Scorpion in León, Guanajuato Alfredo Luis Chávez-Haro1, Josué Saúl Almaraz-Lira1, Jorge Alejandro González-Canudas2, Aarón Molina-Perez2, Ana Gabriela Amador-Hernández2 and Walter Garcia-Ubbelohde2* 1Mexican Red Cross, Leon Delegation, Mexico 2Laboratorios Silanes, Research and Clinical Trials Unit, Mexico Abstract Introduction: Being Mexico one of the countries with the highest diversity in species of scorpions, their population is at a greater risk of being poisoned by scorpion sting. The objective of this study was to analyze the change in temperature at the sting site and describe the clinical evolution of patients treated between May and September 2017. Methods: Descriptive, longitudinal, prospective study realized in the Red Cross Antialacran Center of Leon, Guanajuato in patients older than 6 years requiring specific treatment for scorpion sting. The variables of study are presented descriptively while baseline temperature in sting site and temperature after leaving the center were compared with t student's test. Additionally we performed a post hoc comparison analysis between antivenom treatments available during the time of this evaluation. Results: One seventy four cases were analyzed, 51.1% were men, average age of 31.8 years, and 44.2% were classified as poisoning grade I; 48.9% as grade II and 6.9% as grade III. The reported mortality was zero. The average temperature at Sting site prior to treatment was 35.83°C and in contralateral site of 36.24°C. Hospital discharge mean temperature was 36.22°C at the sting site while in contralateral site was 36.37°C.
