Pandinus (Pandinus) Trailini Sp Pandinus (Pandinus) trailini sp. n. from Ethiopia (Scorpiones: Scorpionidae), with Data on Localities and Life Strategy František Kovařík August 2013 — No. 163 Euscorpius Occasional Publications in Scorpiology EDITOR: Victor Fet, Marshall University, ‘[email protected]’ ASSOCIATE EDITOR: Michael E. Soleglad, ‘[email protected]’ Euscorpius is the first research publication completely devoted to scorpions (Arachnida: Scorpiones). Euscorpius takes advantage of the rapidly evolving medium of quick online publication, at the same time maintaining high research standards for the burgeoning field of scorpion science (scorpiology). Euscorpius is an expedient and viable medium for the publication of serious papers in scorpiology, including (but not limited to): systematics, evolution, ecology, biogeography, and general biology of scorpions. Review papers, descriptions of new taxa, faunistic surveys, lists of museum collections, and book reviews are welcome. Derivatio Nominis The name Euscorpius Thorell, 1876 refers to the most common genus of scorpions in the Mediterranean region and southern Europe (family Euscorpiidae). Euscorpius is located at: http://www.science.marshall.edu/fet/Euscorpius (Marshall University, Huntington, West Virginia 25755-2510, USA) ICZN COMPLIANCE OF ELECTRONIC PUBLICATIONS: Electronic (“e-only”) publications are fully compliant with ICZN (International Code of Zoological Nomenclature) (i.e. for the purposes of new names and new nomenclatural acts) when properly archived and registered. All Euscorpius issues starting from No. 156 (2013) are archived in two electronic archives: Biotaxa, http://biotaxa.org/Euscorpius (ICZN-approved and ZooBank-enabled) Marshall Digital Scholar, http://mds.marshall.edu/euscorpius/. (This website also archives all Euscorpius issues previously published on CD-ROMs.) Between 2000 and 2013, ICZN did not accept online texts as "published work" (Article 9.8). At this time, Euscorpius was produced in two identical versions: online (ISSN 1536-9307) and CD-ROM (ISSN 1536-9293) (laser disk) in archive-quality, read-only format. Both versions had the identical date of publication, as well as identical page and figure numbers. Only copies distributed on a CD-ROM from Euscorpius in 2001-2012 represent published work in compliance with the ICZN, i.e. for the purposes of new names and new nomenclatural acts. In September 2012, ICZN Article 8. What constitutes published work, has been amended and allowed for electronic publications, disallowing publication on optical discs. From January 2013, Euscorpius discontinued CD-ROM production; only online electronic version (ISSN 1536-9307) is published.

The new species is characterized by 6/4: 6-7/4: 7-8/4-5: 7-8/4-5 spination formula of tarsomere II and only two spines on the inclined anteroventral surface of tarsomere II; 16–18 ventral trichobothria on the chela; and sexual dimorphism, with the male having a more pronounced tooth on the movable finger of pedipalp than the female. A key to species and a distribution map of the subgenus Pandinus Thorell, 1876 are provided. Presented are also photos of localities. Introduction DIAGNOSIS. Total length 60–220 mm.

November 2009 ISSN 0044-5223 Reanalysis of the genus Scorpio Linnaeus 1758 in sub-Saharan Africa and description of one new species from Cameroon (Scorpiones, Scorpionidae) W ilson R. Lourenço (with 32 figures) Abstract For almost a century, Scorpio maurus L., 1758 (Scorpiones, Scorpionidae) has been considered to be no more than a widespread and presumably highly polymorphic species. Past classifications by Birula and Vachon have restricted the status of different populations to subspecific level. In the present paper, and in the light of new evidence, several African populations are now raised to the rank of species. One of these, Scorpio occidentalis Werner, 1936, is redescribed and a neotype proposed to stabilise the taxonomy of the group. A new species is also described from the savannah areas of Cameroon. This is the second to be recorded from regions outside the Sahara desert zone. Keywords: Scorpiones, Scorpionidae, Scorpio, new rank, new species, Africa, Cameroon. Introduction The genus Scorpio was created by Linnaeus in 1758 (in part), and has Scorpio maurus Linnaeus, 1758 as its type species, defined by subsequent designation (Karsch 1879; see also Fet 2000).

Accepted 16 January, 2014 Leuirus quinquestriatus, Androctonus amoreuxi and Androctonus australis are venomous scorpion in Egypt. Their venom is complex mixture of salts, neurotoxins, peptides and proteins which has therapeutic applications, and can rapidly kill a broad range of microbes. Estimations of total proteins of the venom indicated that L. quinquestriatus had the highest value than the others (10.64 ± 0.04). Hemolytic activity of human erythrocytes was detected and showed that all concentrations (20, 8 and 5 mg/ml) of tested scorpion species crude venom have hemolytic activity against human erythrocytes. The present study was conducted to evaluate the antimicrobial activity of the three Egyptian scorpion’s venom against four Gram-positive and negative bacterial strains (Bacillus cereus, Bacillus subtillis, Citrobacter freundi and Klibsella pneumonia) in addition to one fungus species Candida albicans. The results show that L. quinquestriatus venom has a significant antibacterial effect against B. subtillis and C. freundi. In contrast, A. amoreuxi and A. australis venoms do not have a noticeable effect on tested microbes. So, the aim of the present study was to investigate the antimicrobial activity of crude venom against Gram-negative, as well as Gram-positive bacteria, fungi and to evaluate the hemolytic activity of the three investigated species on human erythrocytes.

  • Emperor Scorpion Class: Arachnida
    Pandinus imperator Emperor Scorpion Class: Arachnida. Order: Scorpiones. Family: Scorpionidae. Other names: Imperial Scorpion Physical Description: One of the largest of scorpions in the world, the emperor scorpion has a dark body ranging from dark blue/green through brown to black and reaches lengths up to 8”. The large pincers are blackish-red and have a granular texture. The front part of the body is made up of four sections, each with a pair of legs. Behind the fourth pair of legs are comb-like structures known as pectines, which are sensory appendages that brush the substrate as the scorpion walks. The pectines are paired and can are used to distinguish sexes, as the ventral appendages are longer in males than females. The tail is long and curves back over the body ending with a large receptacle containing the venom glands and tipped with the sharp, curved stinger. Sensory hairs cover the pincers and tail, enabling the scorpion to detect prey through air and ground vibrations. Diet in the Wild: Insects, arachnids, mice and small lizards Diet at the Zoo: Crickets Habitat & Range: The emperor scorpion is found in western Africa and Congo areas, typically in hot and humid forests. They reside in burrows and prefer to live under leaf litter, forest debris, rocks, stream banks, and also in termite mounds Life Span: 5 to 8 years in captivity. Lifespan is likely shorter in the wild. Perils in the wild: Bats, birds, small mammals, large spiders, centipedes, large lizards and other scorpions Physical Adaptations: Eyesight of emperor scorpions is very poor.

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.

The buthid Centruroides altagraciae n.sp. was found in several localities at the eastern tip of the island (La Altagracia province), whereas the diplocentrine Heteronebo barahonae n.sp. was captured at a single site of the northeastern section of the Bahoruco Range (Barahona province). Both taxa are compared in detail with their closest relatives, with abundant illustra- tions of habitus, main morphologically diagnostic characters and habitat.
