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...

The need for a refined scorpion antivenom for Iran

Abstract

Scorpion sting is a medical burden globally but especially frequent hotspots of scorpion biodiversity. In Iran, one of those hotspot countries, many fatalities occur in the South as well as the Southwest and are thought to be caused by Hemiscorpius lepturus. Accordingly, those are used for antivenom production. However, recent surveys revealed that indeed a different species Hemiscorpius acanthocercus is responsible for most accidents in the South, while H. lepturus is primarily causing the fatalities in the Southwest and thus Iranian scorpion antivenom needs to be refined in that respect. Such a refined antivenom would need to cover both species of Hemiscorpius. In response, the Iranian government requested the adjustment of the production line from local antivenom suppliers but until today no action has been taken.
