  • A new species of Centruroides (Scorpiones: Buthidae) from Quiché,
           northwestern Guatemala

    • Authors: Rony E. Trujillo et al.
      Abstract: A new species of the genus Centruroides Marx, 1890 is described from Sotzil Village (15.61775°N, -91.09745°W, 1173 m a.s.l.), Chajul Municipality, Quiché Department, Guatemala, on basis of one female and one male. It closely resembles Centruroides caral Armas et Trujillo, 2013 from northeastern Guatemala (240 Km southeast of Chajul), but male differs by having a most globose pedipalp manus, as well as metasoma clearly more attenuate (len-gth/width ratio: segments II–IV = 2.4, 2.7 and 1.4, respectively; 1.7, 2.2 and 2.5 in the holotype of C. caral, the only known specimen of this taxon). Data on its habitat and some biogeographical comments are also given.

  • Scorpions of the Horn of Africa (Arachnida: Scorpiones). Part IX.
           Lanzatus, Orthochirus, and Somalicharmus (Buthidae), with description of
           Lanzatus somalilandus sp. n. and Orthochirus afar sp. n.

    • Authors: František Kovařík et al.
      Abstract: The rare Horn of Africa buthid genera Lanzatus Kovařík, 2001, Orthochirus Karsch, 1891, and Somalicharmus Kovařík, 1998 were newly collected. Lanzatus is reported for the first time from Somaliland, and Orthochirus for the first time from Ethiopia. We describe two new species, Lanzatus somalilandus sp. n. from Somaliland, and Orthochirus afar sp. n. from Ethiopia, both discovered during scorpiological expeditions in 2011–2016. Information is provided for all Horn of Africa species belonging to these three genera: their taxonomy, distribution, and ecology, fully complemented with color photos of live and preserved specimens, as well as their habitat. The morphology of the enigmatic scorpion Somalicharmus whitmanae Kovařík, 1998 is illustrated in detail. The first author recently collected 52 specimens including the first known females, which reveal natural colors, and show sexual dimorphism in the shape of the pedipalp chela and metasoma which are broader in males, and in the shape of the basal middle lamella of the pectines, which in females is extremely dilated and rounded. We describe the hemispermatophore, which is furnished with an atypically elongated basal lobe, and the chelicera, which differs from that of all other known extant buthids. Other characters indicate possible affinity with the south African buthid Karasbergia methueni Hewitt, 1913. We also describe karyotypes of S. whitmanae. We identified 2n=20 in seven males from two localities and 2n=21 in one male. In both analyzed localities we found males with reciprocal translocations that form conspicuous multivalents. The male with 2n=21 includes fission of one chromosome that increases the diploid number and implicates an odd number of chromosomes.

  • Another new species of Euscorpius Thorell, 1876 from the Taurus Mountains
           in Antalya Province, southern Turkey (Scorpiones: Euscorpiidae)

    • Authors: Gioele Tropea et al.
      Abstract: A new scorpion species, Euscorpius alanyaensis sp. n., is described based on specimens collected from the Taurus Mountains in Antalya Province (Alanya District) in southern Turkey. It is a sibling species of the recently described E. gocmeni Tropea et al., 2014, and similarly, the new species is also characterized by a high trichobothrial count (Pv = 9–11, et = 7, em = 4, and eb = 4), a high pectinal teeth count (Dp = 9–11 in males, 8 in females), medium-small size, and light to medium brown-reddish colour. In addition, for the first time a phylogenetic analysis (concatenated sequences of 16S rDNA and COI) is performed to reconstruct the relationships between E. gocmeni Tropea et al., 2014, E. koci Tropea et Yağmur, 2015, E. lycius Yağmur et al., 2013, E. avcii Tropea et al., 2012 from Turkey, and the new species herein described, E. alanyaensis sp. n.

  • Scorpions of the Horn of Africa (Arachnida: Scorpiones). Part VII.
           Parabuthus Pocock, 1890 (Buthidae), with description of P. hamar sp. n.
           and P. kajibu sp. n. from Ethiopia

    • Authors: František Kovařík et al.
      Abstract: All Parabuthus species from Eritrea, Ethiopia, and Somaliland were newly collected and are revised for the first time. The complex of Parabuthus liosoma is split into three sibling species with separate areas of distribution: P. abyssinicus Pocock, 1901 (Eritrea, Djibouti, central and north-eastern parts of Ethiopia), P. liosoma (Ehrenberg, 1828) (Yemen and Saudi Arabia), and P. maximus Werner, 1913 (Tanzania and Kenya). P. hamar sp. n. and P. kajibu sp. n., discovered during scorpiological expeditions in 2011–2016, are described. Information is provided about all Parabuthus species from the Horn of Africa, their taxonomy, distribution, and ecology, fully complemented with color photos of live and preserved specimens, as well as their habitat. The hemispermatophores of P. abyssinicus and P. kajibu sp. n. are illustrated and described. In addition to the analyses of external morphology and hemispermatophores, we also describe the karyotypes of P. abyssinicus (2n=16), P. kajibu sp. n. (2n=18), and P. pallidus (2n=20). The monotypic genus Riftobuthus Lourenço, Duhem et Cloudsley-Thompson, 2010 is synonymized with Parabuthus, based in part on pectinal tooth count analysis. Phylogenetic scaling and ontogenetic invariance of pectinal tooth count are shown for buthid scorpions.

  • Graemeloweus, a new scorpion genus from northern California, USA
           (Scorpiones: Vaejovidae)

    • Authors: Michael E. Soleglad et al.
      Abstract: Genus Graemeloweus, gen. nov. (Scorpiones: Vaejovidae) is described from northern California, USA. The genus is composed of three species formerly placed in Pseudouroctonus: Graemeloweus iviei (Gertsch et Soleglad, 1972), comb. nov. (type species), G. glimmei (Hjelle, 1972), comb. nov., and G. maidu (Savary et Bryson, 2016), comb. nov. Major diagnostic characters of Graemeloweus include a non-bifurcated primary lamellar hook, the presence of a secondary lamellar hook, a complex mating plug with a two part base and an asymmetric crescent-shape barb, and the presence of a well-developed ventromedian (V2) carina on the pedipalp chela. Evidence is presented suggesting that Graemeloweus is more closely related to Kovarikia than Pseudouroctonus.

  • A new species of Diplocentrus (Scorpionidae: Diplocentrinae) from western
           Izabal, Guatemala

    • Authors: Luis F. de Armas et al.
      Abstract: Diplocentrus izabal sp. n. is herein described on basis to one male (holotype) and two females from El Estor municipality, Izabal department, eastern Guatemala. It seems to be a close relative of Diplocentrus lachua Armas, Trujillo & Agreda, 2012, from which it differs by having carapace almost smooth, with anteromedian notch V-shaped; pectines with 11 teeth in both sexes, and carapace clearly longer than pedipalp manus and metasomal segment V (D. lachua has carapace minutely granulate, with anteromedian notch U-shaped; pectines with 13 teeth in the males (female unknown), and carapace as long as both pedipalp manus and metasomal segment V).

  • Scorpions of the Horn of Africa (Arachnida, Scorpiones). Part V. Two new
           species of Neobuthus Hirst, 1911 (Buthidae), from Ethiopia and Eritrea

    • Authors: Graeme Lowe et al.
      Abstract: New information about the taxonomy and distribution of the genus Neobuthus Hirst, 1911 (Scorpiones: Buthidae) is presented, based on materials recently collected from Ethiopia and Eritrea. Emended diagnoses are provided for the genus Neobuthus, and for the species N. awashensis Kovařík et Lowe, 2012 and N. cloudsleythompsoni Lourenço, 2001. New records are given for N. awashensis in Ethiopia. We redescribe N. cloudsleythompsoni, and we describe two additional new species: N. eritreaensis sp. n. (the first record of the genus from Eritrea) and N. kutcheri sp. n. (southern Ethiopia, Somali State). We include a key to six members of the genus and discuss possible speciation mechanisms.

  • Neotype designation for Scorpiops pachmarhicus Bastawade, 1992
           (Scorpiones: Euscorpiidae), with redescription and notes on the species

    • Authors: Zeeshan A. Mirza et al.
      Abstract: Scorpiops pachmarhicus Bastawade, 1992 was described based on specimens collected from Pachmarhi, Madhya Pradesh. An expedition to the type locality led to discovery of a population at the type locality which permit us to designate a neotype for the species as types of the species are presently not traceable.

  • Scorpions of Sri Lanka (Scorpiones: Buthidae, Chaerilidae, Scorpionidae)
           with description of four new species of the genera Charmus Karsch, 1879
           and Reddyanus Vachon, 1972, stat. n.

    • Authors: František Kovařík et al.
      Abstract: Data about all 18 known scorpion species of Sri Lanka are summarized. All previously known species were newly collected and four new species discovered during a scorpiological expedition in 2015. Information is provided about their taxonomy, distribution, ecology, and reproductive biology, fully complemented with color photos of live and preserved specimens, as well as their habitat. Subgenus Isometrus (Reddyanus) Vachon, 1972 is elevated to genus level, Reddyanus stat. n., supported by new characters of setation on leg tarsomere II and hemi-spermatophore morphology. Charmus saradieli sp. n., Reddyanus ceylonensis sp. n., R. jayarathnei sp. n., and R. ranawanai sp. n. are described, compared with other species and fully illustrated. Heterometrus serratus (Pocock, 1900) is restored and differentiated from H. indus (Geer, 1778). Charmus minor Lourenço, 2002 is synonymized with Charmus laneus Karsch, 1879; Isometrus garyi Lourenço et Huber, 2002 is synonymized with Reddyanus loebli (Vachon, 1982) comb. n., and Heterometrus spinifer solitarius Couzijn, 1981 is synonymized with Heterometrus indus (Geer, 1778). A key and distribution maps for all 18 Sri Lankan scorpion species are presented. Hemispermatophores of Buthoscorpio sarasinorum (Karsch, 1892), Charmus laneus Karsch, 1879, Isometrus thwaitesi Pocock, 1897, Lychas srilankensis Lourenço, 1997, Reddyanus basilicus (Karsch, 1879) comb. n., R. ceylonensis sp. n., R. loebli comb. n. and Heterometrus gravimanus (Pocock, 1894) are illustrated and described for the first time. In additional to morphological analysis, we also describe the karyotype of Buthoscorpio sarasinorum (2n=14); Charmus laneus (2n=9); Isometrus thwaitesi (2n=8); Lychas srilankensis (2n=16); Reddyanus basilicus comb. n. (2n=15–16); R. ceylonensis sp. n. (2n=16); and R. loebli comb. n. (2n=17). The significance of cytogenetics and hemispermatophore morphology in buthid taxonomy are discussed.

  • New data on the distribution of Butheoloides littoralis Lourenço, Touloun
           et Boumezzough, 2011 (Scorpiones: Buthidae) Oulaid

    • Authors: Oulaid Touloun et al.
      Abstract: Morocco is the region in Africa with the highest diversity of Butheoloides Hirst, 1925 species. Until now, the total number of species of this genus known from Morocco is raised to five. A field study conducted in southern Morocco discovered a new specimen of Butheloides littoralis in the Tighmi region (southeast of Tiznit), the most continental site of this species in Morocco. This specimen is the third of this endemic species of Morocco but it is the first male discovered.

  • DNA barcoding indicates hidden diversity of Euscorpius (Scorpiones:
           Euscorpiidae) in Turkey

    • Authors: Victor Fet et al.
      Abstract: The Anatolian fauna of the genus Euscorpius (Scorpiones: Euscorpiidae) is in the process of reassessment. Twelve species of this genus are currently recognized for Anatolia, of which seven have been recently described on the basis of morphology. We demonstrate additional cryptic diversity in Anatolian Euscorpius by applying molecular markers (mitochondrial COI and 16S rDNA genes) from 14 populations, of which 13 were morphologically characterized by “em=3,” a phenotypic marker on the pedipalp patella. All studied Anatolian forms are strongly supported as a single clade compared to the European (from the Alps to the Balkans) taxa of the subgenus Alpiscorpius. Of these, six are assigned to known species (E. ciliciensis, E. mingrelicus, E. eskisehirensis, E. phrygius, and E. uludagensis); and three (Aksaray, Ankara, Sakarya) are closely related to a clade containing E. phrygius and E. uludagensis. Four clades represent undescribed taxonomic forms, possibly of species level: Balikesir/Canakkale (Kazdağları National Park), Konya, Denizli, and Trabzon, all with em=3. Another putative species from Kayseri Province, Aladağlar (=Antitaurus) Mts., is related to (E. ciliciensis + E. eskisehirensis) clade; however, it exhibits em=4, which appears to be the first case of reversal in this important trait for the genus Euscorpius.
