Abstract

The knowledge of arachnofauna from Tocantins, Brazil, is still incipient. The present communication expands the known geographical distribution of Loxosceles amazonica Gertsch, 1967 (Arachnida: Araneae: Sicariidae) in Brazilian Cerrado. The brown spider specimens were sampled in Dianópolis municipality and Cristalândia municipality both in Tocantins State, Brazil, between 2022 and 2024. Also, we describe a new variation of the epigynum of L. amazonica. Mapping the distribution of Loxosceles Heineken & Lowe, 1832 species in Brazil is crucial for public health, aiding in prevention and timely treatment of loxoscelism caused by brown spider bites.
