A Remarkable Discovery: Exploring a Rare Eresus and Spider Wasp Interaction One of the most rewarding aspects of maintaining Arácnido Taxonomy is hearing from naturalists and photographers around the world who take the time to share their discoveries. Every so often, an email arrives that immediately captures your attention. Not because it claims to rewrite what we know about biodiversity, but because it documents something that very few people have the opportunity to witness. Recently, I was contacted by a naturalist in Sicily who shared a series of exceptionally high-quality photographs of a female ladybird spider ( Eresus ) during what appeared to be an interaction with a spider wasp. Along with the images came a simple question: "Could this be scientifically import...

Abstract

Species of wolf spiders considered in the Pardosa atrata group are surveyed, and comparative figures of all species included in the group are presented for the first time. A new species, P. armeniaca sp. nov., is described from the shore of Lake Sevan (Armenia) based on both sexes. Pardosa narymica Savelyeva, 1972 from East Kazakhstan Oblast’ is synonymized with the trans-Palaearctic P. atrata (Thorell, 1873). It was found that the record of P. atrata (sub P. lapponica) by Schenkel from British Columbia and reflected in the World Spider Catalog in fact refers to P. concinna (Thorell, 1877), a member of the P. lapponica group. The distribution of three species consideredin the atrata group are mapped. The discovery of P. armeniaca sp. nov. has led to a re-evaluation of the distribution range, previously thought to be continuous, now showing a disjunctive pattern.
