Orthochiroides is back again as a valid genus and a new species in the genus from Somaliland is described

 

The genus Orthochiroides  Kovarik, 1998 (Buthidae) was synonymized with Orthochirus Karsch, 1891 by Lourenco & Ythier in 2021. This decision is now changed in a recent article by Kovarik & Lowe after analyzing more than 40 morphological characters. Orthochiroides is back as a valid genus with the original four species previously assigned to the genus.

 A new species Orthochiroides is desrcibed from Somaliland increasing the number of species to five.

Orthochiroides somalilandus Kovarik & Lowe, 2022

An identification key for the genus is included.

Abstract:
The genus Orthochiroides Kovařík, 1998 is reanalyzed. Revised diagnoses and new illustrations for the genus and all four of its species are presented. A new species, O. somalilandus sp. n. from Somaliland is described and illustrated. Phylogenetic relationships of the genus with several other similar genera of small buthids are inferred from a parsimony analysis of 43 discrete morphological characters. The recent synonymy of Orthochiroides with Orthochirus is refuted and the genus is revalidated.

A few taxonomical changes in the genus Orthochirus

 

Wilson Lourenco and Eric Ythier have recently published an article with some taxonomical changes in the genera Orthochirus Karsch, 1891 and Orthochiroides Kovarik, 1998 in Africa (Buthidae).

 Genus Orthochiroides Kovarik, 1998 is synonymized with Orthochirus Karsch, 1891 and the three species belonging to to the former is now in Orthochirus.

Orthochirus arenicola Lourenco & Ythier, 2021 - New species from the coasts of Somalia.

Orthochirus aristidis (Simon, 1882) is restored from its synonymy with Orthochirus olivaceus (Karsch, 1881). 

Abstract:
A new species of buthid scorpion, Orthochirus arenicola sp. n. is described from the coasts of Somalia. The scorpion was collected on the beach sand under bush-like herbaceous vegetation by our late Italian colleague Professor P. M. Brignoli. New considerations are also proposed for other related taxa. Orthochirus afar Kovařík & Lowe, 2016 described from Afar, Ethiopia is suggested to be a synonym of Orthochirus aristidis (Simon, 1882); no final decision is taken however face to the impossibility of consulting the types of Orthochirus afar. Orthochirus aristidis is restored from its synonymy with Orthochirus olivaceus (Karsch, 1881). Finally, the genus Orthochiroides Kovařík, 1998 is placed as a junior synonym of Orthochirus Karsch, 1891.
