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.

A new Centruroides species and first record of C. tapachulaensis Hoffmann, 1932 (Scorpiones: Buthidae) from Honduras

Abstract

A new species of striped bark scorpions, Centruroides lenca sp. n. is described, based on both sexes, from the Pacayita Volcano Biological Reserve (2,385 m a. s. l.), Ocotepeque Department, in the southwestern Honduras. By its general pattern, the new species resembles C. thorellii (Kraepelin, 1891), from which it clearly differs by having stronger and very darker pedipalp chelae, minute subaculear tubercle and basal pectinal plate with a large central pit in the female, among other diagnostic characters. Also, Centruroides tapachulaensis Hoffmann, 1932 is recorded for the first time from Honduras, on the basis of two observed or collected specimens in the Ocotepeque Department. There are currently 12 species of Centruroides known from Honduras, of which three are known only from this Central American country (two other endemic species are C. terueli Armas & Cubas-Rodríguez, 2023, from Guanaja Island, Islas de la Bahía Archipelago, and C. hirsuticauda Teruel, 2011, from Comayagua and Yoro Departments).
