New records of spiders: Araneae, Pisauridae, Salticidae, and Theridiidae from Pakistan

The genus Emertonella Bryant, 1945, with Emertonella taczanowskii (Keyserling, 1886), is recorded for the first time with stable random population distribution, extension of Chinattus mikhailovi Logunov, 2021 towards the southern part with clump pattern of distribution of population, and Perenethis sindica (Simon, 1897) recorded after 127 years with stable random pattern population distribution from the subtropical to the ecotone of the North-West Hindu Kush Peshawar valley, eurytopic species Loxosceles rufescens (Dufour, 1820) reported extended distribution from the subtropical to the Pan Hindukush-Himalaya mountains sub-temperate regions. We observed that synanthropic pressure is due to anthropogenic extension displacing or changing the behavioural ecology of these spiders. The authors point out the adverse effects of human activities, such as habitat destruction and agriculture, which threaten local wildlife and biodiversity. They stress the urgent need for more studies on spiders in Pakistan to fill the gaps in our understanding of the distribution of species in Eurasia. The research involved actively collecting specimens and closely examining them better to understand the patterns in their distribution and ecological roles. The findings call for conservation efforts in the biodiversity-rich Hindu Kush region of Pakistan.
