Abstract:
A synopsis is proposed for all the scorpion species of the genus Ananteris Thorell, 1891 (Scorpiones: Buthidae) collected in French Guiana, including thorough diagnoses and distributional records for each documented species. Four new species are also described, raising the total number of Ananteris species described from French Guiana to eleven. Most species are illustrated, a geographical distribution map is presented and a key to the species is proposed.

The history of Leiurus taxonomy and a new species from Mauritania

Wilson Lourenco has recently described a new species of Leiurus Ehrenberg, 1828 (Buthidae) from Mauritania.

Leiurus dekeyseri Lourenco, 2020

In the article professor Lourenco also sums up the taxonomical history of Leiurus, which until 2002 was believed to be monotypical with only Leiurus quinquestriatus (Ehrenberg, 1828). The knowledge of this genus is important as its species have some of the most potent venoms in the scorpion world.

Abstract:
The aim of this contribution is to bring some precise information on the reasons why the number of noxious scorpion species is constantly growing. This fact is directly associated with the zoological research on the domains generally defined as systematics and taxonomy. The classification of any zoological group is in most cases a source of problem for most biologists not directly involved with this almost confidential aspect of the zoological research. Much information has been gathered and published over two centuries on the classification but it is remains poorly accessible and too technical for non experts. The exposed example could be taken from several groups of scorpions possessing infamous species, but the choice went to the genus Leiurus Ehrenberg, 1828 distributed from North Africa to the Middle East. Maybe this contribution will help to explain why so numerous cases of species misidentification are regularly present in the general literature devoted to scorpion venoms and incidents.

A new species of Buthus from Algeria

From one to many. Buthus occitanus (Amoreux, 1789) (Buthidae) was for many year one species with a large distribution. But it turned out to be a species complex "hiding" numerous species in southwestern Europa and Africa. Wilson Lourenco and co-workers have recently described a another new species belonging to the "Buthus occitanus species complex" from Algeria.

Buthus apiatus Lourenco, El Bouhissi & Sadine, 2020

Abstract:
From the beginning of the 1950s until the early 2000s the composition of the genus Buthus Leach, 1815 remained extremely conservative. Following the preliminary revisions by Lourenço in 2002 and 2003 an increasing number of studies were published, concerning mostly the species associated to the ‘Buthus occitanus’ complex. The status of many populations previously considered as subspecies or varieties of Buthus occitanus (Amoreux, 1889) has been reviewed, and these have been raised to the rank of species. A considerable number of new species have also been described. The majority of the species considered in these studies come from North Africa, but only five new species have been recorded from Algeria. Nevertheless, only the studies conducted in Algeria have been done with precise methods and a clear definition of the populations. In order to stabilise the nomenclature, a new diagnosis is here proposed for the classical species found in Algeria, Buthus paris (C. L. Koch, 1839). One more new species of Buthus is also described, from the region of Sidi Bel Abbès, in the north-western mountains of the country. This new species may represent a possible vicariant element of Buthus saharicus Sadine, Bissati & Lourenço, 2016, known from the central deserts of Algeria. The number of confirmed species of Buthus in Algeria is thus raised to eight.

Taxonomical changes in the genus Grosphus

Wilson Lourenco and co-workers have recently published a study on the genus Grosphus Simon, 1880 (Buthidae) were they critise the taxonomical decisions made in a 2019 study by Graeme Lowe and Frantisek Kovarik. Lourenco et al's conclusion is that they reject most decsisions made in the latter study and in addition they describe one new species.

These are the major taxonomical changes:

The genus Teruelius Lowe & Kovarik, 2019 is placed in synonymy with Grosphus Simon, 1880 and all species in Teruelius is also transferred back to Grosphus.

Grosphus makay Lourenço & Wilmé, 2015 is restored from synonymy of  with Grosphus feti Lourenço, 1996.

Grosphus rossii Lourenço, 2013 is restored from synonymy of  with mahafaliensis Lourenço, Goodman & Ramilijaona, 2004.

Grosphus simoni Lourenço, Goodman & Ramilijaona, 2004, is restored from synonymy of  with Grosphus madagascariensis (Gervais, 1843).

Grosphus halleuxi Lourenço, Wilmé, Soarimalala & Waeber, 2017, is restored from synonymy of  with Grosphus madagascariensis (Gervais, 1843).

Grosphus mandena Lourenço, 2005, is restored from synonymy of  with Grosphus madagascariensis (Gervais, 1843).

Grosphus mavo Lourenco & Rossi, 2020 (New species from Madagascar)

The status according to Lowe & Kovarik, 2019 is summed up here.

There is a great disagreement between the "Lourenco-group" and the "Kovarik-group" when it comes to the taxonomy of several taxa. I do not know who has the correct answer for the genus Grosphus and other taxa as I'm no expert taxonomist. The Scorpion Files tries as far as possible to stay neutral and will publish the latest update for the different scorpion taxa. It is challenging though and a lot of work some times when researchers are correcting each other several times. [This paragraph was edited by the Editor 23.07.20]

Abstract:
The southwestern portion of Madagascar appears to have one of the highest levels of scorpion diversity on the island. In this contribution, the remarkable diversity of the genus Grosphus Simon, 1880 in this region is discussed. A particular attention is aimed to the area of the Cap Sainte Marie where microendemic geographic patterns are observed. These are tentatively explained in the light of some new biogeographic interpretations. A new species is also described from the Cap Sainte Marie and is characterized by a medium body size and a very pale yellow coloration. While this contribution was in preparation,  we learned about the publication of a “most controversial revision” of the genus Grosphus by authors who totally ignored a number of taxonomic particularities of this group and worse, who lack any experience on the ecological and biogeographic patterns observed for the Malagasy fauna. This calls for corrections in which their speculative decisions are refuted.

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.
