A new Euscorpius from Central Italy

It is known that the Euscorpius Thorell, 1876 (Euscorpiidae) fauna of Greece and Balkans are unresolved, but it is for me a little surprising that a new species has now been described from Central Italy by Gioele Tropea. The total number of Italian Euscorpius species is now 10.

Euscorpius celanus Tropea, 2012

The new species is so far only know from the Celano area in the Abruzzo region in Central Italy.

Abstract:
A new species of the genus Euscorpius Thorell, 1876 is described based on specimens collected at the locality Celano (AQ), Abruzzo, central Italy. It is characterized by a peculiar trichobothrial pattern (eba = 5-5 + eb = 4-4), a large number of pectine teeth, and a general colouration which is dark brownish, with legs and telson yellowish. With the description of this new species a new trichobothrial pattern is described. The number of Euscorpius species in Italy is thus raised to ten, and the number of species in the subgenus Euscorpius to five.

A new Plesiochactas from Guatemala

Rony Trujillo and Luis de Armas have recently published a new species of Plesiochactas Pocock, 1900 (Euscorpiidae) from Guatemala.

Plesiochactas vasquezi Trujillo & Armas, 2012

Abstract:
A new species of the scorpion genus Plesiochactas Pocock, 1900 is described on the basis of a single female specimen from the Cerro San Gil Spring Protection Reserve, Izabal department, Guatemala. It differs from P. dilutus Karsch, 1881 by lacking the median carina of sternite VII and from P. mitchelli Soleglad, 1976 by having a higher pectinal tooth count and by the presence of fulcra.

Three new Pandinus from East Africa and a revision of the subgenus Pandinurus

Frantisek Kovarik his continuing his revision of the genus Pandinus Thorell, 1876 (Scorpionidae). He has now published a revision of the subgenus Pandinurus Fet, 1997 from East Africa. Three new species are described and one species is raised to species level from synonymization.

Pandinus awashensis Kovarik, 2012 (new species from Ethiopia)
Pandinus lowei Kovarik, 2012 (new species from Democratic Republic of Congo)
Pandinus somalilandus Kovarik, 2012 (new species from Somaliland)
Pandinus sudanicus Hirst, 1911 (raised to species status from synonymization with P. magrettii, 1901)

The paper has several high quality color photos of scorpions and habitats and also an updated key for the subgenus.

Abstract:
Pandinus (Pandinurus) awashensis sp. n. from Ethiopia, P. (P.) somalilandus sp. n. from Somaliland, and P. (P.) lowei sp. n. from Democratic Republic of Congo are described and compared with other species of the subgenus. P. (P.) sudanicus Hirst, 1911 stat. n. previously considered a synonym of P. (P.) magrettii Borelli, 1901 is recognized as a valid species. New data on taxonomic characters and distribution of the subgenus Pandinurus are presented. Also presented are a map of distribution, photos of the localities and a key to species using hitherto unpublished characters of the tarsomere spination formula and sexual dimorphism.

A new Buthus from Egypt

As I have mentioned several times in this blog, the taxonomy and phylogeny of the genus Buthus Leach, 1815 (Buthidae) is a challenge, but fortunately there is an increasing research interest in this genus. Wilson Lourenco has now published a new species from Egypt.

Buthus egyptiensis Lourenco, 2012

Abstract:
During the last decade, the genus Buthus Leach, 1815 (family Buthidae) was the subject of several studies. These concerned in particular the ‘Buthus occitanus’ complex of species. Several populations previously considered as subspecies or varieties were raised to the rank of species and many new species were also described. Most of the species considered in these studies come from Northwest Africa. At present, therecords of the genus Buthus in Egypt from other regions than Sinai are questionable, but a new record from the region of Siwa is confirmed and the description of a new species, Buthus egyptiensis, is provided.

The genus Brotheas in Brazil and a new species

Wilson Lourenco has recently published a geographical survey of the genus Brotheas C. L. Koch, 1837 (Chactidae) in Brazil. A new species is also described.

Brotheas tapajos Lourenco, 2012


Abstract:
A geographical survey is presented of the species of the genus Brotheas C. L. Koch, distributed in Brazilian Amazonia. Since some of these species are yet poorly characterized, diagnoses are proposed and their geographical distribution is discussed. A new species is also described on the basis of one male specimen collected in the state of Pará, Brazil. The new species, Brotheas tapajos, is characterized by reddish-brown coloration, the carapace only slightly convex and body and appendages with punctations.

A new species of Pseudochactas from Afghanistan

Photo: Michael Misch (C)

The discovery of the enigmatic Pseudochactas ovchinnikovi Gromov, 1998 from Central Asia and a new family, Pseudochactidae, was undoubtedly one of the most important discoveries in scorpion systematics in recent times. Now a second species of this genus has been described from south-central Afghanistan.

Pseudochactas mischi Soleglad, Kovarik & Fet, 2012 (Pseudochactidae)

The new species is named after Michael Misch, who collected the name species in Afghanistan and made it available to the authors of this paper. Congratulations, Michael, and thanks for your contributions to The Scorpion Files!

Abstract:
A new species of the rare genus Pseudochactas Gromov, 1998 is described from south-central Afghanistan. The species, P. mischi, sp. nov., is compared in detail to its northern sister species P. ovchinnikovi Gromov, 1998, known from Uzbekistan and Tajikistan. P. mischi, sp. nov. is a smaller, lighter colored species and has a considerably more robust metasoma, telson, and pedipalp chelae. Biogeographical observations on the genus Pseudochactas are provided.

New Urodacus from Australia

Its holiday time, but I'm trying to post a message on the blog using a shaky internet connection from our cabin.

Erich Volschenk and co-workers have published a new Urodacus (Scorpionidae*) from western Australia.

Urodacus butleri Volschenk, Harvey & Prendini, 2012

*The status of the family Urodacidae is under discussion. Some authors have included the Urodacus in Scorpionidae and abolish the family, while others have retained Urodacidae as a valid family.

Abstract:
A new urodacid scorpion, Urodacus butleri, n. sp., is described from Barrow Island and the Pilbara bioregion of Western Australia. This species is unusually dark in color; it is compared and contrasted with three morphologically similar species, Urodacus manicatus (Thorell, 1876), Urodacus novaehollandiae Peters, 1861, and Urodacus planimanus Pocock, 1893.
