  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...

Revision of the monotypic genus Chinchaysuyu Ferretti et al., 2023 from Peru (Araneae; Theraphosidae; Theraphosinae)

Abstract

The Peruvian tarantula genus ChinchaysuyuFerretti et al., 2023 is revised. Another female specimen of Chinchaysuyu  spinosaFerretti et al., 2023 was found in the distribution area of this species. The female has two short hypersclerotized seminal receptacles. Two pairs of seminal receptacles of female paratype of Chinchaysuyu spinosa are considered an anomaly. Homologous keels of male palpal bulb are newly proposed. The genus Chinchaysuyu is rediagnosed, differing from all known genera in the presence of type III urticating setae placed in one dorsal patch on abdomen, in combination with the palpal bulb with prolateral superior, prolateral inferior, subapical keel and the non-homologous ventral keel, subparallel with subapical keel and prolateral keels, in the presence of spiniform setae on ventral maxillae, the reduced number of labial cuspules, the presence of long spiniform setae retrolateral on male cymbial lobe, and the female spermatheca consisting of two separate hypersclerotized receptacles.
