New data on the distribution of Buthiscus bicalcaratus in Algeria

 


 Zineb Souilem and co-workers have recently published an article presenting new distribution records and range extension for the Saharan scorpion Buthiscus bicalcaratus Birula, 1905 (Buthidae) in Algeria.

Abstract:
This study includes new distribution records and range extension for the Saharan scorpion Buthiscus bicalcaratus Birula, 1905 in Algeria, where new specimens were collected from several localities across diverse biotopes. These findings document a significant expansion of the species, both northward and southwestward, providing important insights into its ecological adaptability and contributing to a better understanding of the environmental changes affecting arid and semi-arid regions. It will be crucial to keep focus on B. bicalcaratus in order to comprehend the ecological factors influencing its variations in range and to use the species as a measure of desertification in North Africa.
