A New Species Of The Genus Centruroides Marx, 1890 (Scorpiones: Buthidae) From Guatemala, Luis F. De Armas, Rony E. Trujillo

Euscorpius

A new species of the genus Centruroides Marx, 1890 is described from northeastern Guatemala on basis to an adult male. By its general pattern and slight sexual dimorphism, the new species looks like C. flavopictus (Pocock, 1898), a larger species from Veracruz, Mexico, with higher pectinal tooth count (males: 21 to 24 teeth) and stronger subaculear tubercle. It also resembles Centruroides chamulaensis Hoffmann, 1932, from Chiapas, Mexico, a smaller species with small to obsolete subaculear tubercle, stronger metasomal carinae, pedipalp chelae narrower than patella, and anterior margin of carapace almost straight (V-shaped in the new species).

A Review Of Androctonus Finitimus (Pocock, 1897), With Description Of Two New Species From Pakistan And India (Scorpiones, Buthidae), František Kovařík, Zubair Ahmed Jan 2016

A Review Of Androctonus Finitimus (Pocock, 1897), With Description Of Two New Species From Pakistan And India (Scorpiones, Buthidae), František Kovařík, Zubair Ahmed

Euscorpius

We describe Androctonus robustus sp. n. and A. cholistanus sp. n. from Pakistan and India and compare them with A. finitimus (Pocock, 1897), whose holotype we have studied. These three species are closely related and form a group that has hitherto been considered one species. They share coloration and are close to each other in geographic range. However, these three species can be reliably distinguished morphologically, primarily based on morphometry of male metasoma, which is widest in A. robustus sp. n. and narrowest in A. cholistanus sp. n.


A New Species Of Buthus Leach, 1815 From Libya (Scorpiones: Buthidae), Andrea Rossi, Gioele Tropea, Ersen Aydın Yağmur Jan 2016

A New Species Of Buthus Leach, 1815 From Libya (Scorpiones: Buthidae), Andrea Rossi, Gioele Tropea, Ersen Aydın Yağmur

Euscorpius

Although Libya covers a very wide territory in northern Africa, only two species of the genus Buthus have been recorded from this country: B. tunetanus (Herbst, 1800) and B. barcaeus Birula, 1909. In the present study, a third species, Buthus lourencoi sp. n., closely related to Buthus egyptiensis Lourenço et Cloudsley-Thompson 2012, is described from west Libya, around the area of Tripoli. An identification key for the scorpions of the genus Buthus (Leach, 1815) that occur in Algeria, Tunisia, Libya, and Egypt is provided.


A New Species Of Tityus C. L. Koch, 1836 (Subgenus Brazilotityus Lourenço, 2006) From The Dominican Amber (Scorpiones: Buthidae), Wilson R. Lourenço Jan 2016

A New Species Of Tityus C. L. Koch, 1836 (Subgenus Brazilotityus Lourenço, 2006) From The Dominican Amber (Scorpiones: Buthidae), Wilson R. Lourenço

Euscorpius

Tityus (Brazilotiyus) hartkorni sp. n., a new species of fossil scorpion belonging to the genus Tityus C. L. Koch and to the subgenus Brazilotityus Lourenço, is described from a specimen in amber from the Dominican Republic. The new species is clearly associated with the extant fauna of the Neotropical region. This discovery attests to a considerable degree of diversity in the Dominican amber-producing forests.

Description Of A New Species Of Leiurus Ehrenberg, 1828 (Scorpiones: Buthidae) From Southеastеrn Turkey, Ersen Aydın Yağmur, Halil Koç, Kadir Boğaç Kunt

Euscorpius

Leiurus abdullahbayrami sp. nov. is described from Southeastern Turkey and compared with other species of the genus, in particular with L. quinquestriatus, which was previously misidentified from Turkey. The new species is readily distinguished from other members of the genus by pedipalp chela and metasomal segments that are distinctly shorter than in L. quinquestriatus; metasomal segment V has large and rounded lobes; trichobothrium db on the fixed finger of pedipalp is located between trichobothria est and esb (in L. quinquestriatus it is located between et and est). All known Turkish populations of Leiurus were examined and found to represent the ...


Morphological Variation Of Mesobuthus Martensii (Karsch, 1879) (Scorpiones: Buthidae) In Northern China, Lu Zhang, Ming-Sheng Zhu Jan 2016

Morphological Variation Of Mesobuthus Martensii (Karsch, 1879) (Scorpiones: Buthidae) In Northern China, Lu Zhang, Ming-Sheng Zhu

Euscorpius

Comparative statistical analysis of morphology of Mesobuthus martensii and Mesobuthus eupeus (Scorpiones: Buthidae) indicated highly significant differences between these two species. Mann-Whitney U test showed that: except Ca_L/AW, Ca_AW/PW and Met-V_L/H in female, Ca_AW/PW and Met-V_L/H in male, all morphometric ratios demonstrated significant differences between M. martensii and M. eupeus. Principal component analysis (PCA) showed that M. martensii and M. eupeus are clearly different species in morphology. Three statistical analyses (Kruskal-Wallis one-way ANOVA, PCA and cluster analysis) were applied to M.martensii from 27 confirmed localities in five provinces of northern China. The results suggested ...

A New Hottentotta Birula, 1908 From Afghanistan, With A Note On The Generic Position Of Mesobuthus Songi Lourenço, Qi Et Zhu, 2005 (Scorpiones: Buthidae), Rolando Teruel, Jan Ove Rein

Euscorpius

A new species of Hottentotta Birula, 1908 is described from the Kabul area in Afghanistan; this addition represents the fifth species of this genus confirmed for this Middle East country. It is a member of the “Indian group” of the genus (the first one recorded from Afghanistan), and is most closely related to Hottentotta jabalpurensis Kovařík, 2007, Hottentotta stockwelli Kovařík, 2007, Hottentotta tamulus (Fabricius, 1798) and Hottentotta songi (Lourenço, Qi et Zhu, 2005) n. comb., which is herein demonstrated to be a member of Hottentotta and is thus formally transferred to this genus.


A New Lithophilic Compsobuthus Vachon, 1949 (Scorpiones: Buthidae) From Northern Oman, Graeme Lowe Jan 2016

A New Lithophilic Compsobuthus Vachon, 1949 (Scorpiones: Buthidae) From Northern Oman, Graeme Lowe

Euscorpius

A new species of Compsobuthus is described from the Al Hajar mountains of northern Oman. It is distinguished by a strongly dorsoventrally compressed body, reduced carination on the carapace and tergites, extreme elongation of legs and pedipalps, lack of external accessory denticles on the pedipalp fingers, chelal trichobothrium est placed closer to dt than db, heavy setation on the ventral metasoma, and 28–34 pectine teeth. It is an ultralithophilic scorpion, highly adapted to life in narrow rock fissures.

With the description of Androctonus maroccanus sp. n., the total number of Androctonus species known to Morocco is raised to seven.


New Picobuthoid Scorpions (Scorpiones: Buthidae) From Oman, Graeme Lowe Jan 2016

New Picobuthoid Scorpions (Scorpiones: Buthidae) From Oman, Graeme Lowe

Euscorpius

Five new species of diminutive buthid scorpions are described from Oman. Two belong to Microbuthus Kraepelin, 1898, a genus with heavily sclerotized, smooth, strongly pitted posterior metasomal segments, abbreviated telson, and pedipalps with 9 femoral and 6–7 external patellar trichobothria: M. gardneri, sp. nov., from the Al Hajar Mountains, and M. kristensenorum, sp. nov., from the Dhofar Mountains and Hadhramaut of Yemen, which was long misidentified as M. pusillus Kraepelin, 1898. Two additional new species are placed in a new genus Picobuthus, gen. nov., differentiated by granular posterior metasomal segments, elongate telson, pedipalps with 7–9 femoral and 5 ...


Tityus Ythieri Lourenço, 2007 Is A Synonym Of Tityus Magnimanus Pocock, 1897 (Scorpiones: Buthidae): A Combined Approach Using Morphology, Hybridization Experiments, Chromosomes, And Mitochondrial Dna, František Kovařík, František Šťáhlavský, Tereza Kořínková, Jiří Král, Tom Van Der Ende Jan 2016

Tityus Ythieri Lourenço, 2007 Is A Synonym Of Tityus Magnimanus Pocock, 1897 (Scorpiones: Buthidae): A Combined Approach Using Morphology, Hybridization Experiments, Chromosomes, And Mitochondrial Dna, František Kovařík, František Šťáhlavský, Tereza Kořínková, Jiří Král, Tom Van Der Ende

Euscorpius

Diagnostic morphological differences to distinguish between two scorpion species, Tityus ythieri Lourenço, 2007 and T. magnimanus Pocock, 1897 do not exist; moreover, the two easily hybridize to produce fertile offspring. Therefore, we suggest that T. ythieri is a synonym of T. magnimanus. This conclusion is further supported by (1) very similar distribution of relative sizes of chromosome bivalents in both species, (2) regular pairing of homologous chromosomes in meiosis of their hybrids, and (3) identical sequences of mitochondrial DNA (COI) markers.


The True Identity Of Scorpio (Atreus) Obscurus Gervais, 1843 (Scorpiones, Buthidae), Wilson R. Lourenço, Elise-Anne Leguin Jan 2016

The True Identity Of Scorpio (Atreus) Obscurus Gervais, 1843 (Scorpiones, Buthidae), Wilson R. Lourenço, Elise-Anne Leguin

Euscorpius

The true identity of the scorpion Scorpio (Atreus) obscurus Gervais, 1843 is discussed based on new data. The original type material was recently discovered in the collections of the Muséum national d’Histoire naturelle in Paris, which confirms that this old species, originally described by Gervais based on two female specimens from French Guiana, does indeed belong to the genus Tityus C. L. Koch, 1836. Furthermore, an analysis of all morphological characteristics of Tityus (Atreus) obscurus verifies its position as a senior synonym of both Tityus paraensis Kraepelin, 1896 and Tityus cambridgei Pocock, 1897. In this paper, we designate the ...


The Geographic Pattern Of Distribution Of The Genus Rhopalurus Thorell, 1876 In The Guayana-Amazon Region (Scorpiones: Buthidae), Wilson R. Lourenço Jan 2016

The Geographic Pattern Of Distribution Of The Genus Rhopalurus Thorell, 1876 In The Guayana-Amazon Region (Scorpiones: Buthidae), Wilson R. Lourenço

Euscorpius

A new discussion is proposed on the geographic patterns of distribution presented by the species of the genus Rhopalurus Thorell, inhabiting the savannah formations of the northern South America. Two lineages of Rhopalurus species are defined for this region, each one containing forms with very weak morphological differences, a consequence of only a minor process of differentiation. The observed pattern of distribution and differentiation is suggested to be directly associated with more or less recent palaeoclimatic vicissitudes, which took place in tropical South America during Pleistocene. Two new subspecies are also described, representing new records of Rhopalurus for Brazil and ...

The Sting Of Mesobuthus Gibbosus (Scorpiones: Buthidae): Morphological And Ultrastructural Characterization, Nazife Yigit, Mehlika Benli Jan 2016

The Sting Of Mesobuthus Gibbosus (Scorpiones: Buthidae): Morphological And Ultrastructural Characterization, Nazife Yigit, Mehlika Benli

Euscorpius

The objective of our study is to characterize the morphological and ultrastructural features of the sting of scorpion species Mesobuthus gibbosus (Brullé, 1832) (Buthidae) by using light microscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The venom is delivered by venom ducts, passing through the sting and exiting from the venom pores. Each venom gland has its own venom duct and pore. The venom pores are situated on both sides of the tip of sting. venom ducts are identified in the transverse discussion in this study.

Mesobuthus Nigrocinctus (Ehrenberg, 1828) (Scorpiones: Buthidae) In Turkey: Distribution And Morphological Variation, Ayşegül Karataş

Euscorpius

Distribution of Mesobuthus nigrocinctus is studied and new geographical records are given. As a result of field studies, M. nigrocinctus is recorded from 17 confirmed localities from five provinces in Turkey. Comparative statistical analysis of morphology of M. nigrocinctus and M. gibbosus indicated highly significant differences between these two species. Student’s t-test analysis and Discriminant Function Analysis (DFA) showed that: (a) while all morphometric ratios demonstrated significant differences between M. nigrocinctus and M. gibbosus females, only selected ratios show significant difference in the males (Ca_L/W, Ch_L/W, Met-II_L/H, and Met- V_L/H); (b) among M. nigrocinctus, Adıyaman ...


The Population Structure Of Mesobuthus Gibbosus (Scorpiones: Buthidae) On Koufonisi Island (Central Aegean Archipelago, Greece), Dimitris Kaltsas, Moysis Mylonas Jan 2016

The Population Structure Of Mesobuthus Gibbosus (Scorpiones: Buthidae) On Koufonisi Island (Central Aegean Archipelago, Greece), Dimitris Kaltsas, Moysis Mylonas

Euscorpius

The population structure of Mesobuthus gibbosus was studied over 261 night-hours of sampling during 29 consecutive nights on Koufonisi Island (central Aegean Archipelago, Greece) using the capture-recapture method. The studied population proved to be the densest of all studied scorpion populations in chaparral or intertidal habitats of Mediterranean type ecosystems and even comparable to some populations of desert scorpion species. The negative influence of moon phase on the general activity of the species and synchronization in parturition were the main factors that caused the fluctuations in population density and therefore in the percentage of active scorpions.
