  Erranticosa gen. nov.: a New Genus of Wolf Spiders from East Asia with Notes on its Separation from Lycosa and Hogna (Araneae Lycosidae: Lycosinae) Abstract The taxonomy and systematic position of the Eastern Asian wolf spider Lycosa coelestis L. Koch, 1878 are revised using an integrative approach. Our study highlights distinctive morphological and molecular differences that separate this species from the generotypes of Lycosa Sundevall,1833 and Hogna Simon, 1885, to which L. coelestis was previously assigned. Based on these findings, we establish a new monotypic genus, Erranticosa gen. nov., to accommodate this species, namely E. coelestis comb. nov. We also discuss the results of a preliminary molecular phylogenetic analysis of the subfamily Lycosinae, including Erranticosa gen. nov. Additionally, based on morphological examination of the type material, we reject the synonymy of Lycosa subcoelestis Fox, 1935 with E. coelestis comb. nov., transferring it to Trochosa C.L. Koch, ...

Successful Management of Intravascular Hemolysis Caused by Systemic Loxoscelism With Antivenom: A Case Report

Abstract

Spider bites, particularly from Loxosceles species, pose a public health concern in Mexico. A case of systemic loxoscelism in a 33-year-old woman who developed acute intravascular hemolysis is presented. The patient was successfully treated with blood transfusions and Reclusmyn, a Mexican antivenom. Her clinical and laboratory improvement supports the therapeutic value of antivenom in severe envenomation. This case highlights the importance of early suspicion, recognition, and targeted treatment to prevent complications and improve outcomes.
