A new species of Scorpio from Algeria

 


Eric Ythier and co-workers recently published an article describing a new species of Scorpio Linnaeus, 1758(Scorpionidae) from Atakor volcanic field in the Hoggar massif in the south of Algeria.

Scorpio atakor Ythier, Sadine, Bengaid & Lourenço, 2024

The authors also raise Scorpio trarasensis Bouisset & Larrouy, 1962 to species status after it previously was synonymized with Scorpio maurus maurus Linnaeus, 1758 (it was originally described as a subspecies of S. maurus.

Abstract:
A new species of Scorpio Linnaeus, 1758 is described from the Atakor volcanic field in the Hoggar massif, located in the South of Algeria. Scorpio atakor sp. nov. most certainly represents a vicariant element of Scorpio tassili Lourenço & Rossi, 2016, species equally described from a massif formation, the Tassili N’Ajjer, in the South of Algeria. Both species are distributed in high altitudes in these massifs. Scorpio trarasensis Bouisset & Larrouy, 1962 stat. rev., stat. nov. is also restored from its synonymy with Scorpio maurus maurus Linnaeus, 1758 and raised to species level. The number of confirmed species of Scorpio in Algeria is raised to six.

Two new species of Euscorpius from Bulgaria and Greece

 


Parts of Europe still seem to be an inexhaustible source of new Euscorpius Thorell, 1876 (Euscorpiidae) species. Gioele Tropea and co-workers have recently published a new article describing a new species from Bulgaria and from Greece based on morphological and molecular evidence.

Euscorpius petaberoni Tropea, Fet, Parmakelis & Stathi, 2024 (Known only from Kovachevitsa in the Western Rhodope Mountains in Bulgaria)

Euscorpius trichasi Tropea, Fet, Parmakelis & Stathi, 2024 (Known only from the Mt. Olympos massif in Thessaly in Greece)

Abstract:
Two scorpion species, Euscorpius petarberoni sp. n. (Bulgaria) and E. trichasi sp. n. (Greece), are described based on morphological and molecular evidence; E. petarberoni sp. n. is related to E. popovi Tropea et al., 2015, E. drenskii Tropea et al., 2015, and E. thracicus Kovařík et al., 2020, while E. trichasi sp. n. is related to E. kabateki Kovařík & Šťáhlavský, 2020.

An extensive revision of the genus Olivierus in Xinjiang, China

 


Victoria Tang a co-workers recently published a thorough revision of the genus Olivierus Farzanpay, 1987 (Buthidae) in Xinjiang, China.

Based on both morphological and molecular evidence, Olivierus longichelus (Sun & Zhu, 2010) and O. przewalskii (Birula, 1897) are the only representatives of this genus in this region. The authors also have made the following taxonomical conclusions:

Olivierus (Mesobuthus) bolensis (Sun et al., 2010) is synonymized with Olivierus longichelus (Sun & Zhu, 2010).

Olivierus (Mesobuthus) karshius (Sun & Sun, 2011) is synonymized with Olivierus longichelus (Sun & Zhu, 2010).

Olivierus tarabaevi Fet et al., 2021 is synonymized with Olivierus longichelus (Sun & Zhu, 2010).

Some information about the genus' habitat, distribution and biology is also included.

Abstract:
The genus Olivierus Farzanpay, 1987 in Xinjiang Uygur Autonomous Region, China, is revised based on recently collected topotypes and other populations from 12 localities. Brief differential diagnoses are provided, with colored illustrations and photos in vivo habitus, emphasizing the key characters. Chinese appellations, conservation status, and documentation of behavior and post-envenomation symptoms are also included. Only two species are now recognized for this genus in Xinjiang: O. longichelus (Sun & Zhu, 2010) and O. przewalskii (Birula, 1897), based on both morphological and molecular evidence. The two species exhibit extensive distribution in Xinjiang (China) while also occurring in adjacent countries. Three new synonyms are proposed: Mesobuthus bolensis Sun et al., 2010 = Olivierus longichelus (Sun & Zhu, 2010), syn. n.; Mesobuthus karshius Sun & Sun, 2011 = Olivierus longichelus (Sun & Zhu, 2010), syn. n.; Olivierus tarabaevi Fet et al., 2021 = Olivierus longichelus (Sun & Zhu, 2010), syn. n. Two species, Olivierus extremus (Werner, 1936) and O. hainanensis (Birula, 1904), are likely synonymous with O. martensii (Karsch, 1879). Should future examination confirm this assumption, the total number of species in genus Olivierus would be reduced to 16.

Rich Ayrey - RIP

 


Yesterday I got the sad news from multiple postings on Facebook that Rich Ayrey is no longer among us. Most, if not all of us in the scorpion community knew Rich. Either by personal communication or from his many important contributions in the taxonomy of the family Vaejovidae from Arizona and California.

Around 2011 I had the first contact with Rich when he generously shared some pictures of rare Vaejovis species for me to use in The Scorpion Files. Later he was very helpful by sending me new articles that he had published. And he always added some nice and supportive comments in his emails which I appreciated very much.

Rich will be missed by the scorpion comunity. 

My thought are with Rich's family and friends.

RIP

A new species of Reddyanus from New Caledonia (France)

 


 In a recent paper, Wilson Lourenco has described a new species in the genus Reddyanus Vachon, 1972 (Buthidae).

 Reddyanus kanak Lourenco, 2023

 In this paper Lourenco states that he doesn't accept the decision by Kovarik et al. (2016) to raise the subgenus Reddyanus Vachon, 1972 in Isometrus Ehrenberg, 1828 to genus status. Because of this, the new species is named Isometrus (Reddyanus) kanak in the article.

This decision is done in a short paragraph without any proper justification. Because of this, I have chosen not to accept and include this status change in The Scorpion Files. I have obtained some advice in this matter and also gotten information that there exist unpublished DNA results that support the decision by Kovarik et al. in 2016.

Abstract:
Some considerations are proposed on Isometrus (Reddyanus) heimi Vachon, 1976, species described from New Caledonia, in order to precisely clarify the status of the typical series used by M. Vachon for its description. A new species of Isometrus is also described from wet forests of New Caledonia, representing the third species of this genus recorded from the Island. The new species, similarly to Isometrus (R.) heimi, most certainly represents an endemic element to New Caledonia.

A new species of Centruroides from Guanaja, Islas de la Bahía, Honduras

 


Luis de Armas and Alex Cubas-Rodríguez have recently described a new species of Centruroides Marx, 1890 (Buthidae) from Guanaja, Islas de la Bahía, Honduras.

Centruroides terueli de Armas & Cubas-Rodriguez, 2023

Abstract:
A new species belonging to the species-group Centruroides gracilis is described from Guanaja Island, Islas de la Bahía, in the Honduran Caribbean, on the basis of an adult female. Because of its dorsal pattern it was misidentified as C. caribbeanus Teruel & Myers, 2017, from which it differs by having the metasomal segments more elongate, pedipalp hands with carinae more developed, sternites immaculate (profusely variegated with dark brown in C. caribbeanus) and a shorter aculeus. This is the third species of this genus recorded from the Islas de la Bahía archipelago and the second endemic scorpion known from the area.
