A new species of Tityus from Suriname


Eric Ythier and co-workers have recently published an article on the scorpion fauna of Suriname and described one new species in the genus Tityus C. L. Koch, 1836 (Buthidae).

Tityus kukututee Ythier, Chevalier & Gangadin, 2020

Try to say "kukututee" fast three times! ;)  It means "scorpion" in Ndyuka tongo, one of the Bushinengue (or Maroon) creole languages spoken in eastern Suriname.

Abstract:
A new species of scorpion belonging to the genus Tityus C. L. Koch, 1836, subgenus Archaeotityus Lourenço, 2006 (family Buthidae C. L. Koch, 1837) is described on the basis of material collected in a sandy dry forest formation located in Pierre Kondre, near Carolina, Para District, Suriname. Some comments are also addressed on the related species Tityus clathratus C. L. Koch, 1845 and Tityus mana Lourenço, 2012 and new locality records are provided for T. mana.

A new species of Leiurus from Kuwait



Wilson Lourenco has recently published a new article describing a new species of Leiurus Ehrenberg, 1828 (Buthidae) from Kuwait. This is the most easterly recorc of this genus.

Leiurus kuwaiti Lourenco, 2020

No data are available on the medical importance of the new species, but it should be regarded as potential dangerous as many of the other species in the genus.

Abstract:
A new species of buthid scorpion belonging to the genus Leiurus Ehrenberg is described based on a single female collected in the region of Al-Abraq – Al-Khabari farms in Kuwait. The new species, Leiurus kuwaiti sp. n., shows affinities with Leiurus hebraeus (Birula, 1908) species distributed mainly in Jordan and Israel. The populations from Kuwait and Jordan/Israel apparently are totally isolated by a large and dry region now occupied by the An Nafud desert. Therefore in account of the disrupted distribution and some minor morphological differences presented by the two populations, a new species is proposed to accommodate the population from Kuwait. Further investigations should bring more precise conclusions about the status of these two populations. The type locality of the new species represents the most easterly record of the genus Leiurus in the North range of the Arabian Peninsula and represents the first confirmed record of the genus for Kuwait.

An update on the scorpion fauna of Puerto Rico and its satellite islands


Luis F. de Armas has recently published an update on the scorpion fauna of Puerto Rico with an annotated list of taxa and a key for the genera for the island.

Abstract:
An annotated list of the scorpions of Puerto Rico and its satellite islands (mainly Vieques, Culebra, Caja de Muertos, Magueyes, Desecheo, and Mona), a key for the seven genera present in those insular territories, a key for the three species of Microtityus, and the basic bibliography on taxonomy and natural history are provided. Of the 16 confirmed species described from these Greater Antillean islands, four are known only from a single sex and only one or two adult specimens. Seven species (six of them from the genus Tityus), are endemic to the Puerto Rico Island; Vieques has two species, whereas Mona Island and Culebrita Island have one species each. At least two species are shared with Hispaniola, whereas one is also found in the Virgin Islands. The only introduced species is Isometrus maculatus (De Geer, 1778). The buthid Tityus dasyurus Pocock, 1897, described from “Porto Rico”, likely is not a Puerto Rican taxon.

A new species of Isometrus from southern India



Shauri Sulakhe and several co-authors have recently published an article describing a new species of Isometrus Ehrenberg, 1828 (Buthidae) from southern India.

Isometrus kovariki Sulakhe, Dandekar, Mukherjee, Pandey, Ketkar, Padhye & Bastawade, 2020

Abstract:
A new species of Isometrus (Buthidae) is described from India using integrated taxonomic approach. Isometrus kovariki sp. n. is closely related to I. thurstoni, and differs in morphological features and raw genetic divergence of more than 9%.

A new species of Leiurus from Somaliland


Frantisek Kovarik and Graeme Lowe recently presented the discovery of a new species of Leiurus Ehrenberg, 1828 (Buthidae) from Somaliland.

Leiurus gubanensis Kovarik & Lowe, 2020

Until 2002, Leiurus only comprised of one, very venomous species Leiurus quinquestriatus (Ehrenberg, 1828). As with many other scorpion species with a wide distribution, this taxa also turned out to be a species complex with many hidden species. With the present species, the genus now consists of 13 species.

The genus Leiurus has always been infamous for having the most potent venom of all scorpion species. But it is unclear wether this also apply for all the new species. Until we know more, the best is to regard all the species in the genus as potential dangerous scorpions.

Abstract:
New data are presented on the distribution of the genus Leiurus Ehrenberg, 1828 in the Horn of Africa, Somaliland, acquired during expeditions in 2011–2019. Leiurus gubanensis sp. n. is described from the Guban area, an extremely warm and dry place. The description is fully complemented with color photographs of live and preserved specimens, as well as of their habitats. This increases the known diversity of the genus to 14 species.

A new species of Euscorpius from caves in Croatia and Bosnia-Herzegovina




Gioele Tropea and Roman Ozimec have recently published an article describing a new species of Euscorpius Thorell, 1876 (Euscirpiidae) found in more than 20 cave systems in Croatia and Bosnia-Herzegovina.

Euscorpius biokovensis Tropea & Ozimec, 2020

Ecological notes for the new species are presented and its cave preference is discussed.

Abstract:
Another new, subtroglophile scorpion species is described from Croatia, Euscorpius biokovensis sp. n. It is morphologically and ecologically similar to E. feti Tropea, 2013 but can be distinguished from the latter by a lower number of trichobothria (Pv = 8–9, with mostly 8, and usually et = 6) and pectinal teeth (usually Dp = 7 in males and 6 in females). The new species also has a more northern distribution although in some areas the two species overlap. E. biokovensis sp. n. has been found in more than 20 caves in Croatia, which makes it the most common Euscorpius species found in caves. It has also been found in Bosnia-Herzegovina. Ecological notes on this species are presented.

Three new species of Buthus from Somaliland



Frantisek Kovarik and co-workers have recently published a new article in their series of article on the scorpions of the Horn of Africa. This time materials from Somaliland revealed three new species from this country.

Buthus pococki Kovarik, Stahlavsky & Elmi, 2020 (New species)

Buthus somalilandus Kovarik, Stahlavsky & Elmi, 2020 (New species)

Buthus zeylensis  Pocock, 1900 (Restored from synonymy with Buthus berberensis Lourenço, 2008)

The article has an identification key and a distribution map for the genus Buthus in the Horn of Africa.

Abstract:
New data are presented on the distribution of the genus Buthus Leach, 1815 in the Horn of Africa, mainly in Somaliland, acquired during expeditions in 2011–2019. Buthus berberensis Pocock, 1900, for which the exact locality was not known, was collected again. B. zeylensis Pocock, 1900 is restored from synonymy and elevated to species rank, based on a study of 75 recently collected specimens. Two new species, B. pococki sp. n. and B. somalilandus sp. n., are described, fully complemented with color photographs of live and preserved specimens, as well as their habitats. In addition to the analyses of external morphology we also described karyotypes of selected species. B. awashensis, B. pococki sp. n. and B. zeylensis have karyotypes with 2n=22. The karyotype of B. berberensis possesses 21 chromosomes, probably as a consequence of heterozygous fusion that is evident as a trivalent during postpachytene in this species. A key and distribution map of Buthus in the Horn of Africa (five species) are included.
