Genus Babycurus split into a new genus and two new species from the Arabian Peninsula

Frantisek Kovarik and co-workers recently published a review of the genus Babycurus Karsch, 1886 (Buthidae) resulting into splitting this genus into two genera. The taxanomical decisions from this study are:

Barbaracurus Kovarik, Lowe & Stahlavsky, 2018 (New genus distributed mainly in the Arabian Peninsula and The Horn of Africa). Species included after review:
B. exquisitus (Lowe, 2000) (Previously in Babycurus)
B. prudenti Lourenço, 2013 (Previously in Babycurus)
B. somalicus (Hirst, 1907) (Previously in Babycurus)
B. sofomarensis (Kovarik, Lowe, Seiter, Pliskova &Stahlavsky, 2015) (Previously in Babycurus)
B. subpunctatus (Borelli, 1925) (Previously in Babycurus)
B. ugartei (Kovarik, 2000) (Previously in Babycurus)
B. winklerorum Kovarik, Lowe &Stahlavsky, 2018 (New species from Oman)
B. yemenensis Kovarik, Lowe, Seiter, Pliskova &Stahlavsky, 2015 (New species from Yemen)
B. zambonellii (Borelli, 1902) (Previously in Babycurus)

Babycurus Karsch, 1886 (Strictly African distribution). Species included after review:
B. ansorgei Hirst, 1911
B. brignolii Lourenço & Rossi, 2017 (Declared Nomen Dubia)
B. buettneri Karsch, 1886
B. centrurimorphus Karsch, 1886
B. dunlopi Kovarik, Lowe, Seiter, Pliskova &Stahlavsky, 2015
B. gigas Kraepelin, 1896
B. jacksoni (Pocock, 1890)
B. kirki (Pocock, 1890)
B. melanicus Kovarik, 2000
B. multisubaculeatus Kovarik, 2000
B. pictus Pocock, 1896
B. solegladi Lourenço, 2005
B. taramassoi Borelli, 1919
B. wituensis Kraepelin, 1913

Babycurus ornatus Werner, 1936 is declared as a junior synonym of Lychas burdoi (Simon, 1882).

The article has an identification key for Barbaracurus.

The genus Babycurus Karsch, 1886 sensu lato is split into two genera, a strictly African genus Babycurus, and the new genus Barbaracurus gen. n., which mainly includes species from the Horn of Africa and Arabian Peninsula. Two new species Barbaracurus winklerorum sp. n. from Oman and B. yemenensis sp. n. from Yemen are described, compared with other species, and fully illustrated with color photos of morphology, habitus, live specimens and collection localities. Males of Barbaracurus somalicus (Hirst, 1907) comb. n. and Barbaracurus zambonellii (Borelli, 1902) comb. n. are recorded for the first time and fully illustrated. Babycurus ornatus Werner, 1936 from Mozambique is shown to be a junior synonym of Lychas burdoi (Simon, 1882), a species from the same area. Babycurus brignolii Lourenço et Rossi, 2017 is designated to be a nomen dubium. Hemispermatophores are des-cribed and illustrated to show their differences between the species and genera. Analyses of karyotypes reveal a similar degree of interspecific variability of diploid chromosomal numbers within the genera Babycurus (2n=16–30) and Barbaracurus gen. n. (2n=22–36).

A new species in the genus Alloscorpiops from Myanmar (Burma)

Wilson R. Lourenço and Ondřej Košulič recently published a new article describing a new species of the genus Alloscorpiops Vachon, 1980 (Euscorpiidae) from the northern part of central Myanmar (Burma).

Alloscorpiops viktoriae Lourenço & Košulic, 2018

The article also has information about the habitat for the new species and the distribution and the biogeography of the genus Alloscorpiops.

Among the genera of the family Scorpiopidae Kraepelin, 1905 Alloscorpiops remains yet rather discrete. New species were added to this genus only recently, increasing its number from two to six. Therefore, species of Alloscorpiops can be considered rare and uncommonly collected. One particular new species, Alloscorpiops viktoriae sp. n., is described based on two females and one pre-adult male collected from the northern part of central Myanmar (Burma). The new species presents most features exhibited by scorpions of the genus Alloscorpiops, but it is characterised by a moderate to small size, very strongly marked granulation, and a particular trichobothrial pattern. Aspects of the ecology and distribution of the new species are discussed and compared with those of other species of genus Alloscorpiops.

A new high altitude species of Scorpiops from China

Wilson Lourenco recently published a new species of Scorpiops Peters, 1861 (Euscorpiidae) from Taxkorgan Reserve, Xinjiang, China.

Scorpiops taxkorgan Lourenco, 2018

The new species was collected under stones at 4500-4600 meters. High altitude scorpions are discussed in the article.

Although scorpions have been described from China since the 19th century, it was only in the early 2000s that this fauna has seen a noticeable improvement in terms of the number and diversity of the described taxa. Some regions of China have been extensively prospected, while others remain largely unexplored. The latter is the case for the Province of Xinjiang, in the Extreme West of the country. A few contributions dealing with scorpions from this region are available, but these mainly concern representatives of the family Buthidae. In the present paper, a new species belonging to the genus Scorpiops Peters, of the family Scorpiopidae Kraepelin, is described from the Taxkorgan Natural Reserve. The description is based on one male and one female collected under stones at altitudes of 4500–4600 m. To our knowledge, this is the first species ever described from the Taxkorgan Natural Reserve and may represent an endemic element within the fauna of Xinjiang Province.

A new species of Buthus from Algeria

Wilson Lourenco and co-workers have recently published a new species of Buthus Leach, 1815 (Buthidae) from the region Bou Sâada-M’Sila in Algeria.

Buthus boussaadi Lourenço, Chichi & Sadine, 2018

Since the early 2000s the genus Buthus Leach, 1815 has been the subject of an increasing number of studies. These have concerned in most cases the species belonging to the ‘Buthus occitanus’ complex and have led to a revision of the status of many populations previously considered as subspecies or varieties of Buthus occitanus (Amoreux, 1889) which have been raised to the rank of species. A noticeable number of new species have also been described. The majority of the species considered in these studies come from North Africa but only four new species were recorded from Algeria. One more new species of Buthus is herein described from the region of Bou-Sâada-M’Sila, in the northern range of the country. This new species may represent a possible vicariant element of Buthus saharicus, known from the central deserts of Algeria. The number of confirmed species of Buthus found in Algeria is raised to seven.
