An article has been published in the journal Zootaxa in which scientists from the Institutes of Zoology of the Russian Academy of Sciences and the Republic of Kazakhstan describe a new genus of tarantulas and four species of spiders previously unknown to science.
The deserts of Central Asia, which at first glance may seem lifeless, continue to surprise. In the international journal Zootaxa (DOI: 10.11646/zootaxa.5782.2.3), scientists from the Zoological Institute of the Russian Academy of Sciences (St. Petersburg, Russia) and the Institute of Zoology of the Republic of Kazakhstan have published a paper in which a new genus of tarantulas (= fossorial wolf spiders) and four species new to science are described.
At the center of the study is the new genus Desertosa, comprising spiders from the lowland deserts of Kazakhstan and Uzbekistan. The genus includes six species, four of which — Desertosa karamola, D. kuramin, D. ozernoyi and D. zyuzini — are described by the authors as new to science. The status of two previously known species has been revised, and they have also been assigned to the new genus.
New discoveries are not only dry scientific facts but also stories about people.
One of the species, Desertosa zyuzini, is named in honor of the prominent arachnologist Aleksey Alexandrovich Zyuzin (1951–2021), who made a significant contribution to the study of spiders in Kazakhstan.
Another species, Desertosa ozernoyi, is named after the Kazakhstani researcher Anatoly Vladimirovich Ozernoy, who collected the specimens used in the study.
In addition to describing new species, the researchers compiled a distribution map and developed an identification key to assist other scientists and naturalists in recognizing representatives of the genus Desertosa.
At present, the fauna of tarantulas in Central Asia and adjacent regions already includes more than 52 species from 10 genera. However, the new study clearly demonstrates that harsh desert ecosystems still hold many scientific mysteries and undescribed species.
The discovery of the new genus and new species highlights the importance of continuing research on the biodiversity of Kazakhstan and Central Asia. Only by understanding which species inhabit our ecosystems can we effectively conserve them in a changing environment.
