However, isolated thrombocytopenia without fibrinogen depletion is less recognised and may alter transfusion strategy. We report a confirmed  Ovophis tonkinensis  bite from northern Vietnam presenting with severe isolated thrombocytopenia and local necrosis. The case highlights the importance of serial platelet monitoring, awareness of fibrinogen availability and appropriate timing of antivenom and platelet support in resource-limited tropical settings.

On the Tarantula Genus Xenesthis Simon, 1891, with Description of a New Species from Venezuela (Araneae: Theraphosidae)

Abstract

The type material of Xenesthis colombiana Simon, 1891, X. immanis Ausserer, 1875, and X. monstrosa Pocock, 1903, are redescribed, with additional specimens of X. colombiana recorded. A neotype is designated for Xenesthis intermedia Schiapelli and Gerschman, 1945, as the holotype is lost; the female is redescribed, and the male is described for the first time. A new species, Xenesthis avanzadora sp. nov., is described from Venezuela based on a holotype male.
