Snakebite epidemiology in the State of Mexico, Mexico 2003-2024

  Snakebite epidemiology in the State of Mexico, Mexico 2003-2024 Abstract In the State of Mexico, several venomous snakes have low median lethal doses, which therefore pose serious health risks. We analyzed the epidemiology of snakebites from 2003 to 2024 and examined their relationship with demographic, socioeconomic, and biological factors. Incidence rates and demographic characteristics were calculated, and Getis-Ord Gi* statistics were used to identify snakebite hotspots. We also applied Non-Metric Multi-Dimensional Scaling (NMDS) to explore associations between hotspot categories and socioeconomic conditions. The potential distribution of 14 venomous snake species was modelled to estimate venomous snake diversity across municipalities. A total of 3,972 cases were reported, with an increasing trend over time. Most bites occurred in summer, affecting mainly males aged 25-44. Hotspot analysis identified 27 municipalities as hotspots, 50 as not significant and 48 as coldspots. So...

A New Species of the Medically Important Scorpion Genus Hemiscorpius Peters, 1861 (Hemiscorpiidae Pocock, 1893) from Kurdistan, Iraq

Abstract

The scorpion genus Hemiscorpius Peters, 1861 is renowned for its medically important species, particularly Hemiscorpius lepturus Peters, 1861, the type species of the genus and only species previously recorded in Iraq. However, the scorpion diversity of the rugged, arid landscapes of the Kurdistan Region, especially Erbil Governorate, in northern Iraq, remains largely unknown. Extensive fieldwork in Erbil Province in 2024 resulted in the discovery of a previously unknown species, described herein as Hemiscorpius kurdistanus sp. n. The Halgurd-Sakran Mountains in the Bradost Region, to which it appears to be endemic, probably played a role in its speciation, providing a barrier that contributed to geographical isolation. The new discovery supports the hypothesis that Kurdistan represents an area of endemism for arthropods due to its isolation and unique environmental conditions. The addition of a new, potentially medically important scorpion species to the Iraqi fauna emphasizes the need for continued studies on the systematics of Hemiscorpius and other scorpion taxa as well as updated public health awareness and envenomation management strategies across the Middle East.
