  An integrative description of Euscorpius diagorasi sp. n. from Rhodes, Greece (Scorpiones: Euscorpiidae) Abstract The genus  Euscorpius  Thorell, 1876 comprises a diverse and taxonomically challenging group of scorpions in the Mediterranean, with Greece representing one of its principal centers of diversity. In this study, we provide an integrative description of  Euscorpius diagorasi   sp. n. , a new species from Rhodes Island, Greece. The new species is described on the basis of adult male and female morphology and mitochondrial COI sequence data. It is a small oligotrichous species characterized by a total length of approximately 21–25 mm, pale yellow to light brown coloration with darker reddish-brown pedipalps, pectinal tooth count of 8 in the male and 7 in the females, Pv = 7–8, Pe-et = 5–6, and a distinct mitochondrial lineage. Phylogenetic analyses based on COI recovered the Rhodian specimens as a strongly supported monophyletic lineage, sister to...

Endemic Scorpion Species and Subspecies in Morocco: A Comprehensive Overview

ABSTRACT

Scorpion fauna is abundant in regions with arid and semi-arid climates, exposing these areas to a risk of envenomation, especially for children. Scorpion envenomations cause thousands of deaths each year, with notable incidences in the MENA region, South America, Latin and Central America, and India. Morocco is one of the countries most affected by this phenomenon; according to statistics from the Moroccan Poison Control and Pharmacovigilance Center (CAPM), approximately 8,565 scorpion stings and envenomations were recorded annually between 2016 and 2022, mainly among children. A literature review was conducted to identify and catalog the endemic scorpion species in Morocco and explore the impact of climate change on their distribution. Sources included scientific journal articles, university theses, and field reports. The collected data were compiled and analyzed to create a distribution map of the endemic species. Our results identified fifty-five endemic species and subspecies in Morocco. The family Buthidae is the most widespread, with seventeen endemic species of the genus Buthus, nine of the genus Androctonus, five of the genus Butheoloides, four of the genus Buthacus, two each of the genera Orthochirus, Compsobuthus, and Hottentota, and one species each of the genera Microbuthus, Cicileiurus, and Saharobuthus. The family Scorpionidae includes nine endemic species, and two subspecies belonging to the genus Scorpio. A high level of endemism is observed in southern Morocco, highlighting a significant concentration of these species in this region. Ongoing climate change is likely to expand the population and distribution of scorpions, as well as the number of envenomations. The results underscore the importance of implementing control and prevention strategies to reduce the risks of envenomation, particularly in the context of climate change. Therefore, to develop management and prevention strategies is based on a thorough understanding of species distribution and their habitats to improve the safety of vulnerable populations.
