Hidden diversity in plain sight: four new species of Nemesia (Araneae: Mygalomorphae) from the Córdoba Province of Spain

  Hidden diversity in plain sight: four new species of Nemesia (Araneae: Mygalomorphae) from the Córdoba Province of Spain Abstract A taxonomic revision of the species of Nemesia Audouin, 1826, distributed in the vicinity of Córdoba City, southern Spain, is presented. Four new species are described: Nemesia morana sp. nov. (female), N. kodama sp. nov. (male and female), N. rosae sp. nov. (male and female), and N. tamajoni sp. nov. (male and female). These species are distinguished by distinct morphological characters, including the shape of the spermathecae, palpal bulbs, and spinnerets, as well as by burrow architecture. Fieldwork was conducted across two of the three major habitat types in the region—the humid, forested mountains of Sierra Morena and the croplands and riparian forests of the Guadalquivir Valley—while the third, the “campiña”, which is mainly composed of agricultural landscapes, remains poorly explored. Sampling methods included pitfall trapping and the direct e...

One new species of Drapetisca Menge, 1866 (Araneae, Linyphiidae) from Gele Mountain, Chongqing, China

Abstract

Background

The genus Drapetisca comprises 7 species distributed in Canada, Central Asia, China, Caucasus, Europe, Japan, Russia (Europe to the Far East), and the USA, out of which five species have been recorded in China (World Spider Catalog 2025). The males and females of Drapetisca can be distinguished from all other Linyphiidae genera by the palpal distal arm of the paracymbium anchor-shaped in the retrolateral view and the protruding epigyne without a scape.

New information

While examining Linyphiidae Blackwall, 1859 specimens from Gele Mountain in Chongqing, we discovered a new species of the genus DrapetiscaD. dentata sp. nov. Detailed descriptions, photographs of copulatory organs and somatic features, and a distribution map are provided.
