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.

Five new Heteropoda species from Southeast Asia (Sparassidae: Heteropodinae)

Abstract 

Five new species of the genus Heteropoda from Southeast Asia are described: H. asa spec. nov. (Indonesia: Kalimantan; male), H. dede spec. nov. (Malaysia: Sabah; female), H. josephkohi spec. nov. (Brunei: Temburong; male, female), H. saracenoi spec. nov. (Indonesia: Flores; male, female), and H. singaporensis spec. nov. (Singapore; male, female). Most of them exhibit special palpal features like embolic apophyses or outgrowths, conductor apophyses, additional RTA branches or, in one case, a unique opisthosomal shape.
