  Snakebite knowledge among healthcare workers in Gabon: A health facility-based cross-sectional survey Abstract Background Snakebite envenoming remains a neglected health issue in many countries, including Gabon, where the limited availability of snakebite-specific training, clinical guidelines, and essential resources at health facilities may lead to gaps in healthcare workers’ knowledge and confidence and the use of non-recommended treatment practices. This study aimed to assess healthcare workers’ knowledge of snakebite management in the Ogooué et des Lacs department of Moyen-Ogooué province in Gabon. Methods From June to August 2023, we conducted a cross-sectional survey targeting all healthcare workers in Ogooué et des Lacs who may be involved in snakebite management. We collected information on prior training, self-perceived knowledge of snakebite management, symptom recognition, clinical management practices, and snake identification. Knowledge was assessed using 10 true/fa...

On one of the smallest Amazonian scorpions: a new species of Microtityus Kjellesvig-Waering, 1966 (Scorpiones, Buthidae) from Brazil, with amended diagnosis and potential distribution analysis for the genus

A new scorpion species, Microtityus adriki n. sp., is described based on adult specimens collected in Cantá, state of Roraima (RR), northern Brazil. Microtityus adriki n. sp. is the second species of Microtityus Kjellesvig-Waering, 1966 known from Brazil and is one of the smallest scorpion species (12.39-19.47 mm) in the Amazonian region. In this study, we propose an amended generic diagnosis and a specific diagnosis, describe the male hemispermatophore of Microtityus, give the sequence of COI barcode, and present a potential distribution analysis for the genus. The morphology of the male hemispermatophore of Microtityus differs from that of other Neotropical buthid genera, except for the number of lobes (three lobes), which is a character state shared with several genera. The potential distribution model generated by MaxEnt suggests high environmental suitability for the genus in the Antilles and northern South America, with scattered high suitability in several regions of Central America. However, the model did not indicate high suitability in areas where Brazilian species occur (i.e., Microtityus adriki n. sp. and Microtityus vanzolinii Lourenço & Eickstedt, 1983), and this could be explained by a sampling bias. Therefore, future studies, including extensive sampling, are required to better understand the biogeographic processes behind the distribution of this genus.
