Four new species of Harmonicon F. O. Pickard-Cambridge 1896 from Brazil with the first male description of H. rufescens (Araneae: Mygalomorphae: Dipluridae) Abstract Four new species of Harmonicon F. O. Pickard-Cambridge 1896 are described from the Cerrado biome of Brazil. Three new species are from Tocantins state, in the North region of Brazil: H. arraias n. sp. (♂), H. palmas n. sp. (♂♀), H. tocantins n. sp. (♂), and one new species is from Mato Grosso state, in the Central-west Brazil: H. guimaraes n. sp. (♂♀). Furthermore, we here describe for the first time the male of H. rufescens F. O. Pickard-Cambridge 1896 and expand the distribution range of this species and that of H. candango Wermelinger-Moreira, Castanheira & Baptista 2024.

Two rare wetland spider species new to Slovakia: Larinia elegans Spassky, 1939 and Tetragnatha reimoseri (Roșca, 1939) (Araneae, Araneidae, Tetragnathidae)

Abstract

We report the first Slovak records of Larinia elegans Spassky, 1939 and Tetragnatha reimoseri (Roșca, 1939) based on adult females and a juvenile from wetland habitats in western and southern Slovakia. These findings extend the known Central European ranges for both species. The finding of T. reimoseri adds a new locality within its fragmented European distribution, whereas the record of L. elegans contributes to a more comprehensive understanding of its overall distribution. Diagnostic characters, photographs of specimens, and habitat details are provided to support identification and future monitoring efforts.
