  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...

Three new species of the segmented spider genus Songthela (Araneae: Mesothelae: Liphistiidae) from Guizhou, China

Abstract

Three new species of the primitively segmented spider genus Songthela Ono, 2000 are described from Guizhou, China: S. chunguang sp. nov. (♂♀), S. congjiang sp. nov. (♂♀), and S. jinxing sp. nov. (♂♀). All three species are assigned to the multidentata-group based on morphology of the male palps and female genitalia. Detailed diagnoses, descriptions, photographs and a distribution map are provided. Mitochondrial cytochrome c oxidase subunit I (COI) sequences of the holotypes are also presented to facilitate future identification and molecular studies.
