Description of Typhloseiulus anatolicus sp. nov. and redescription of two new records of Phytoseiidae (Acari: Mesostigmata) from Turkey

Abstract

Surveys were carried out to determine Phytoseiidae (Acari: Mesostigmata) species in oak plantations (Quercus spp., Fagaceae) in different regions of Turkey. As a result, Typhloseiulus anatolicus sp. nov. Döker is described and illustrated based on female and male specimens. The new species is placed in the simplex species group of Tsolakis and Ragusa due to the elongated calyx of spermatheca. It differs from its congeners by having seta J2 more than six times longer than seta j6, and seta S5 about three times longer than seta R1 as well as eight setae on genu II, in the female. In addition, Typhlodromus (Anthoseius) rapidus Wainstein and Arutunjan, and Paraseiulus incognitus Wainstein and Arutunjan are reported for the first time for the Turkish fauna. Although T. (A.) rapidus was reported for the Turkish fauna by an earlier study, we consider the previous report invalid, because it shows three pairs of preanal setae as opposed to four pairs in the original description and the material examined in this study. Furthermore, P. incognitus is removed from junior synonymy with P. soleiger and redefined. Therefore, in this study, we retain these two species as distinct species due to differences in their adenotaxy.

Review of the genus Paraseiulus Muma (Acari: Phytoseiidae) of Russia

“…Therefore, it is likely that the slides loaned by Wainstein to Chant & Yoshida-Shaul contained P. intermixtus sensu Kolodochka (1983), but not the true P. incognitus sensu Kolodochka (1983) incognitus but absent in P. soleiger; and poroids iv2 are located out of sternal shield in P. incognitus vs. on sternal shield in P. soleiger. The morphometric and morphological characters of the specimens examined in this study agree well with those of the original description and redescriptions (Kolodochka 1983;Döker et al 2023).…”

“…We consider the specimens reported as P. soleiger from China (Wu et al 1992;Wu et al 2009) as misidentifications and should be attributed to P. xiningensis. Furthermore, we follow the suggestion of Kolodochka (2006) and Döker et al (2023) that P. incognitus Wainstein & Arutunjan, 1967 is a valid species and not a junior synonym of P. soleiger. Thus, at the moment, a total of seven valid species of Paraseiulus are present in Russia.…”
