  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).

Three new genera of wolf spiders (Araneae, Lycosidae) living on the forest floor in East Asia

Abstract

Three new genera as well as one new species belonging to Lycosidae are described, Houcosa gen. nov. (type species: Houcosa zhaoi sp. nov., ♂♀), Kuncosa gen. nov. (type species: Arctosa ningboensis Yin, Bao & Zhang, 1996) and Loongcosa gen. nov. (type species: Pardosa dentitegulum Yin, Peng, Xie, Bao & Wang, 1997). Seven new combinations are proposed: Kuncosa fujiii (Tanaka, 1985), comb. nov., K. hikosanensis (Tanaka, 1985), comb. nov., K. kwangreungensis (Paik & Tanaka, 1986), comb. nov., K. ningboensis (Yin, Bao & Zhang, 1996), comb. nov. (all ex. Arctosa), K. zhui (Yu & Song, 1988), comb. nov., Loongcosa dentitegulum (Yin, Peng, Xie, Bao & Wang, 1997), comb. nov. and L. wuyiensis (Yu & Song, 1988), comb. nov. (all ex. Pardosa). The male of Kuncosa ningboensis and the female of Loongcosa dentitegulum are described for the first time. Detailed descriptions of copulatory organs and somatic features of the new and known species are provided, along with photographs and a distribution map.
