  A new species of Dolomedes Latreille, 1804 (Araneae: Dolomedidae) from the island of New Guinea Abstract A new species, Dolomedes afi sp. n., is diagnosed and described from New Guinea Island (Papua New Guinea) based on both sexes. The new species is similar to the Australian species D. alexandri Raven & Hebron, 2018, D. vicque Raven & Hebron, 2018 and D. wollemi Raven & Hebron, 2018, but differs from them in the structure of the copulatory organs. The new species exhibits pronounced sexual dimorphism in body coloration. A detailed description and digital photographs are provided. The collecting localities of Dolomedes species in New Guinea are mapped. Fomichev, A. A., & Omelko, M. M. (2026).

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.
