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

- 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.

- A new species of the genus Thaicharmus
Kovařík, 1995 (Scorpiones: Buthidae) from northeast India
Authors: Zeeshan A. Mirza et al.
Abstract: A new species Thaicharmus guptai sp. nov. is described from the northeast Indian state of Tripura. The new species differs from the known members of the genus in the following set of morphological characters: large size (total length 45.6 mm); trichobothrium d2 is distal to i1 on femur; trichobothria est, em and et on the external surface of the patella do not form a straight line. Subaculear tubercle is absent. The movable finger of pedipalp chela has 12 cutting rows of denticles. The movable finger is much longer than the pedipalp patella. Number of pectinal teeth 20/19; pectines with distinct lamellae and fulcra. Two horn-like projections are present on the ventrolateral aspect of the metasomal segment V.

- Pseudouroctonus peccatum Tate et al., 2013,
Authors: Richard F. Ayrey
Abstract: Shortly after the discovery of Pseudouroctonus peccatum Tate, Riddle, Soleglad et Graham, 2013 (Scorpiones: Vaejovidae) there was a large wildfire in the Spring Mountains of Nevada. At the time the species description was published, it was noted that the only known population of this species may have been extirpated by the fire and subsequent flooding of the type locality habitat (Tate et al. 2013). Today it is certain that the species has survived after the collection of 12 new specimens. Additional data on males are also presented.

- Two new Chaerilus from Vietnam (Scorpiones,
Chaerilidae), with observations of growth and maturation of
Chaerilus granulatus sp. n. and C.
hofereki Kovařík et al., 2014
Abstract: Chaerilus granulatus sp. n. and C. longimanus sp. n. from Vietnam are described and compared with other species of the genus. Both species are characterized by: median eyes present; movable finger of pedipalp with 7–9 rows of granules; total length of adults under 30 mm; male differing from female in having pedipalp chela much narrower and longer. The two new species are differentiated by: ventral sides of sternite VII are smooth in C. longimanus sp. n. and granulated in C. granulatus sp. n. Adults of both sexes of C. granulatus sp. n. and C. hofereki Kovařík et al., 2014 were raised from birth and their exuviae were retained and compared to the mature adults. Hemisper-matophores of C. granulatus sp. n. and C. hofereki were extracted and illustrated. Karyotype of male holotype of C. granulatus sp. n. consists of high number of chromosomes (2n=96).
