“…In addition, we also observed several pore-like structures at least on femora and genua II and III which are located at the connection of the following segments (Figures 33–36). Based on our best knowledge, these pore-like structures have never been reported for the family Phytoseiidae but known for other groups of Mesostigmata (Lindquist & Moraza 2023).…”

Taxonomy of the predatory mite family Phytoseiidae (Acari: Mesostigmata) is essentially based on morphological observations, and only a few studies use integrative approaches that include mainly morphological and molecular analysis. Species of the genus Euseius Wainstein (Acari: Phytoseiidae) are pollen feeding generalist predators belonging to “Type IV” group. There are more than 200 species of the genus that are considered to be valid. However, there could be a series of synonyms among these valid species. Euseius gallicus Kreiter & Tixier is one of the recently described species and its natural populations have been reported from a total of 10 countries. There are some molecular studies showing that E. gallicus represents a different lineage and separated adequately from the other well-known and common species, E. stipulatus in the Western Palearctic region. However, it shows great morphological similarities with E. amissibilis Meshkov, a species previously described from Tajikistan. According to its original description, these two species can be separated based on a few differences in their setal lengths, but doubts remain regarding the similarities between them. Therefore, we examined the type material of E. amissibilis, and newly collected materials from various localities including the type locality. We conducted molecular analyses, using two gene markers (ITS and Cox1) to determine whether these two species are conspecific. Results show that all morphological characters and measurements of the type and the newly collected materials of E. amissibilis fall within the range indicated in the original description of E. gallicus. Moreover, zero and low levels (≤6% previously considered as variation for phytoseiid mites) of genetic distances were detected among the specimens of these two species from different populations based on ITS and Cox1 gene markers, respectively. As conclusion, this study confirms that E. gallicus is a junior synonym of E. amissibilis. In addition, based on our best knowledge, a ventral pore-like structure located on ambulacral stalk of the first leg is observed for the first time in a species of the family Phytoseiidae, probably even in the order Mesostigmata.

“…ZV3, JV4 in N. barkeri; also ZV1 in Nc-AH; Chant & Yoshida-Shaul, 1991). In addition, gnathosomal structures other than the chelicerae can differ between sexes, particularly the hypostome: (1) the males of N. barkeri and N. californicus sensu Athias-Henriot both have convergent, wellseparated corniculi, which are (2) flanked medially by a pair of hyaline lobes, whereas females have closely parallel corniculi and have no such lobes (Figs 21-22 vs 23-24); these lobes, present only in the male, have already been observed in N. barkeri (Ueckermann & Loots, 1988: 149), and in other Phytoseioidea (Lindquist & Moraza, 2016); (3) the hypostome itself projects anteriorly to a greater extent in females than in males of both species, so that the external bases of corniculi and internal malae are well separated from h setae in females, but relatively close to h setae in the 'contracted' hypostome of males; (4) the internal malae of N. barkeri females are shorter, more hyaline and more rounded apically than in males, but not in N. californicus sensu Athias-Henriot in which they are identical between the sexes. Therefore, the inclusion of the male dorsal shield in descriptions, as well as the subcapitulum, in addition to other sexually dimorphic features (chelicerae; sternal and opisthogastric regions differing in the extent of sclerotisation), may provide useful diagnostic and phylogenetic information, especially given that the male has been described for only a limited number of species.…”

In 1954, McGregor described two species of phytoseiids from lemon, in California, USA: Typhlodromus californicus McGregor and T. mungeri McGregor, the former represented by one male, and the latter by two females. Since its description, T. mungeri was synonymised under T. californicus, and the name T. (now Neoseiulus) californicus has been used extensively to represent a species that is now commonly used as a biocontrol agent of crop pests worldwide. However, the true identity of the biocontrol agent is uncertain because the original descriptions of T. californicus and T. mungeri were not adequate enough to allow an irrefutable identification, with each description being based on specimens of a single sex. An examination of the types of N. californicus and N. mungeri revealed that they are morphologically identical to the male and female of N. barkeri Hughes, 1948, respectively, and that they are in fact junior synonyms of N. barkeri—and are therefore distinct from the biocontrol agent globally called N. californicus (sensu Athias-Henriot, 1977; see Griffiths, 2015). This is further supported by a comparison with male and female syntypes of N. barkeri, as well as other specimens of N. barkeri including some collected from the type host in the vicinity of the type location (i.e. lemon in southern California, 1952–1958). We redescribe the male and female of both N. barkeri and N. californicus sensu Athias-Henriot (1977), based on representative specimens from at least 14 and 19 populations, respectively. Based on examination of types, we confirm the synonymy of N. mckenziei (Schuster & Pritchard, 1963), N. picketti (Specht, 1968), and N. oahuensis (Prasad, 1968) with N. barkeri, and that the names N. chilenensis (Dosse, 1958b) and N. wearnei (Schicha, 1987) represent the same species as N. californicus sensu Athias-Henriot (1977). We also provide a hypothesis as to why Chant (1959) had erroneously synonymised T. californicus and T. mungeri under T. marinus (Willmann). Finally, we suggest maintaining the prevailing usage of the name N. californicus (McGregor) for the species concept of Athias-Henriot (1977) as followed by subsequent authors, through submission of a separate application to the International Commission of Zoological Nomenclature (ICZN). In the meantime, the current meaning of N. californicus should be maintained until a ruling by the ICZN is made on the application.

“…It is unclear whether this gland opening is homologous to the one ( gp ) typically found in the poststigmatic region of peritrematal shields in many Mesostigmata (e.g. Lindquist and Moraza 2016). This double pore-like structure also occurs in Zygoseius papaver sp.…”
