Envenomization with Snake Versus Scorpion Venom: Postmortem Repercussions on the Successional Dynamics of Carcass-Attracted Flies in a Forensic Context

  Envenomization with Snake Versus Scorpion Venom: Postmortem Repercussions on the Successional Dynamics of Carcass-Attracted Flies in a Forensic Context Abstract Background: Animal venoms may alter postmortem carcass conditions and thereby influence carrion-associated insects. However, it remains unclear whether lethal envenomization affects adult Diptera as a broad assemblage-level response or as taxon-specific changes during decomposition. Methods: Fifteen rabbits were assigned to control, snake-envenomized, or scorpion-envenomized treatments (with five carcasses each). Carcasses were exposed under semi-natural conditions, until complete dryness, over 11 days postmortem. Adult flies were collected daily for analyzing abundance at total, family, and selected species levels, using negative GLMM, with carcass identity as a random effect and postmortem day as a nonlinear predictor. Results: A total of 5497 adult flies representing 13 species in seven families was recorded. Total fly...

A New Species of Scorpio from Saudi Arabia (Scorpiones: Scorpionidae) 

Abstract

A new species of Scorpio Linnaeus, 1758 is described from Al Ula Governorate, Al Madinah Province, Saudi Arabia. Scorpio furvus sp. nov. is distinguished from closely related congeners, including S. fuscus, S. kruglovi, S. palmatus, S. jordanensis, and S. yemenensis, by a unique combination of morphological characters notably the granulation pattern of the pedipalp chela, metasomal proportions, pectinal structure and length, and overall dark coloration. Morphometric comparisons further support its distinct status. The discovery of this species highlights the underestimated diversity of the genus Scorpio in the Arabian Peninsula and reinforces the view that the Scorpio maurus complex comprises multiple geographically restricted taxa requiring continued integrative taxonomic investigation.
