Unlike traumatic compartment syndrome there have been no documented cases of ischemic limb injury after envenomated patients have received antivenom. Furthermore, there is experimental evidence that fasciotomy worsens myonecrosis. This has led medical toxicologists and surgical guidelines to shift from liberally recommending fasciotomy to near universal recommendation of antivenom alone. Despite this, fasciotomies continue to be recommended and performed on rattle...

New record of Ischnothele annulata (Mygalomorphae: Ischnothelidae) in San Juan extends its known western range

Abstract

We report the first record of Ischnothele annulata (Mygalomorphae: Ischnothelidae) for the province of San Juan, Argentina. This finding extends its known distribution, marking a new western limit with the nearest locations being Chepes and Quines in La Rioja and San Luis, respectively. The observed population is within the arid region of central-western Argentina, at the ecotone between the Arid Chaco and the Monte Desert.
