  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...

Taxonomic notes on a comb-footed spider, Yunohamella mneon (Bösenberg & Strand, 1906), stat. rev. (Araneae: Theridiidae) in East Asia

Abstract

Platnickina mneon (Bösenberg & Strand, 1906) is a theridiid species originally described based on a female specimen collected in Saga Prefecture, Kyushu, Japan. Although P. mneon was recently considered a junior synonym of Yunohamella lyrica (Walckenaer, 1841), the two species can be clearly distinguished by body coloration and markings, genital morphology, and molecular data. Based on these findings, we reestablish P. mneon as a valid species under the genus Yunohamella, Yunohamella mneon stat. rev. Based on a partial mitochondrial COI gene sequence analysis, our study also revealed that the female of Y. mneon stat. rev. is conspecific to the male currently associated with Yunohamella varietas Lee & Kim, 2021 and we propose Y. mneon stat. rev. = Y. varietas syn. nov. The species is compared with Y. lyrica and Platnickina adamsoni Berland, 1934 and molecular data of Yunohamella species in East Asia are presented, with a summary of the taxonomic history of relevant species in Japan and Korea.
