Russian species of the genus Paraseiulus Muma (Acari: Phytoseiidae) were reviewed based on the material collected in this study as well as previous literature reports. As a result, a new species, P. pseudoincognitus sp. nov., collected from leaves of Ulmus sp. (Ulmaceae) in Omsk Region, Russia, was described and illustrated from adults of both sexes. Moreover, supplementary descriptions and new illustrations of four species, P. incognitus Wainstein & Arutunjan, P. soleiger (Ribaga), P. triporus (Chant & Yoshida-Shaul) and P. xiningensis (Chen & Chu) were provided, based on the newly collected specimens to facilitate species delimitation. In addition, P. intermixtus Kolodochka was proposed as a new junior synonym of P. soleiger, and both P. trimediosetus (Xin, Liang & Ke) and P. inobservatus Kolodochka were synonymized with P. xiningensis. Identification key for the Russian species of the genus was provided.

“…Many previous descriptions of phytoseiid species lack some important morphological characteristics including the number of dorsal solenostomes. In contrast, a series of identification keys are used the number of dorsal solenostomes for species delimitation in certain phytoseiid genera including Neoseiulus (Ragusa di Chiara & Tsolakis 1994;Kolodochka 2006;Papadoulis et al 2009;Kreiter et al 2010;Ferragut & Ueckermann 2012). Indeed, the importance of the presence or absence of a single pair of solenostomes to distinguish two otherwise identical species in some phytoseiid genera, such as Kampimodromus and Neoseiulus has previously been confirmed by molecular studies (Tixier et al 2008;Döker et al 2018;Khaustov et al 2022).…”

“…In contrast, a great variability has been reported for the genera Eharius Tuttle & Muma, Kampimodromus Nesbitt, Neoseiulus Hughes, Paraseiulus Muma, and Typhlodromus Scheuten (Papadoulis et al 2009;Döker et al 2018). Therefore, a series of identification keys established by many phytoseiid experts are used to separate closely related species based on the number of dorsal solenostomes in the aforementioned genera (Ragusa di Chiara & Tsolakis 1994;Kolodochka 2006; Papadoulis et al 2009;Kreiter et al 2010;Ferragut & Ueckermann 2012). Indeed, the importance of a single pair of solenostomes (gd8) to separate closely related species in the genus Kampimodromus, has previously been confirmed by molecular analyses in several cases (Tixier et al 2008;Döker et al 2018).…”

Many previous descriptions of Phytoseiidae (Acari: Mesostigmata) species lack some important morphological characteristics including the number of dorsal solenotomes (gland pores). However, the importance of the presence or absence of a single pair of solenostomes to identify two distinct species in some phytoseiid genera, such as Kampimodromus Nesbitt and Neoseiulus Hughes has previously been confirmed by molecular studies in several cases. Neoseiulus marginatus (Wainstein) was originally described from Kazakhstan, a country located in Central Asia, based on the specimens collected from herbaceous plants. It was subsequently reported and redescribed from a series of Western Palearctic countries. However, the material first redescribed from Crimea and thereafter from Armenia, Greece, Israel, and Turkey, by having gd5 solenostomes, is distinct from the original N. marginatus described by Wainstein. Indeed, our examinations of its type specimens confirmed that gd5 pores are consistently absent in the type series of N. marginatus. Therefore, this species is redescribed and illustrated based on the female lectotype. In addition, N. pseudomarginatus sp. nov., a widely distributed species in the Western Palearctic countries, which has seven pairs of solenostomes is described as a new taxon for science. Furthermore, our examinations of the type specimens of N. polyporus (Wainstein) indicated that it should be considered as a junior synonym of N. marginatus, as already suggested in earlier studies.

Internal Transcribed Spacer (ITS) sequences of some Kampimodromus (Acari: Phytoseiidae) species: Is Kampimodromus ragusai a valid species or a synonym of Kampimodromus aberrans?

Taxonomy of the most important predatory mite family Phytoseiidae (Acari: Mesostigmata) is essentially based on morphological observations, and only a few studies use molecular approaches. In some cases, tiny morphological differences (e.g. number of teeth on cheliceral digits, presence of dorsal solenostomes) should be observed for accurate species identification. Kampimodromus ragusai Swirski & Amitai, originally described from Israel, was suspected as a junior synonym of K. aberrans (Oudemans) in an earlier study. The only difference between these two species is the presence or absence of a tooth on the movable digit (MD) of chelicera. In this study, we conducted molecular analyses, using the Internal Transcribed Spacer (ITS) marker, to determine whether K. ragusai is synonymous to K. aberrans or a valid species. DNA sequences of several populations of three other Kampimodromus species collected from Croatia and Italy were included to the study. ITS sequences of other Kampimodromus species deposited in the public GenBank database were also used. Results revealed a 5% genetic distance between K. ragusai and K. aberrans (Jukes & Cantor model). In the phylogenetic tree, K. ragusai is located in a different clade clearly separated from all other K. aberrans. Therefore, these results validate that K. ragusai and K. aberrans are altogether two distinct species. Presence or absence of a tooth on MD of chelicera is a reliable morphological character to differentiate these two species. Additionally, a GenBank sequence deposited as K. aberrans is identical to K. corylosus Kolodochka. This result clearly demonstrates the importance of combining molecular and morphological data to phytoseiid taxonomy, and the need to generate reliable data in publicly available gene bank databases.
