782353158616FF96FF36FBF966B2E0B8.taxon	etymology	Etymology. The name of this species refers to the high altitude of the type locality (acro -). Taxonomic notes. Mašán (2007) evaluated the species grouping of some species of the genus Onchodellus and found five species groups and some non-grouped species. The Onchodellus karawaiewi group includes three species, namely O. karawaiewi, O. montivagus Mašán, 2007 and O. zoborensis Mašán, 2007. The characters of this species group are presented in detail by Mašán (2007). Onchodellus acrophilus can be included in this species group, and is most similar to O. zoborensis. It distinctly differs from O. karawaiewi and O. montivagus in body shape (oval in O. karawaiewi and O. montivagus), a different number of setae on the soft integument of the idiosoma (14 pairs in O. karawaiewi and O. montivagus), a difference in the relative length of J 4 / J 5 (1.7 – 3.04 in O. karawaiewi, 1.3 – 1.7 in O. montivagus), shorter setae J 4, 48 – 56 (56 – 73 in O. karawaiewi, 56 – 62 in O. montivagus) and subcircular shaped gdZ 1 (circular shaped in O. karawaiewi and O. montivagus). In addition, O. acrophilus differs from the most similar species O. zoborensis by shorter setae J 5 (23 – 26 in O. acrophilus, 37 – 42 in O. zoborensis), a different number of setae on the soft integument of the idiosoma (14 pairs in O. zoborensis), a different relative length of J 4 / J 5 2.08 – 2.34 (1.3 – 1.7 in O. zoborensis) and subcircular shaped gdZ 1 (circular shaped in O. zoborensis). The male specimens of these species are generally similar except for the process on leg II, but there is an important difference in the middle segments of leg IV. The males of this group have a triangular process on the distal part of the ventral side of the femur, genu and tibia of leg IV, which is absent in the male of O. acrophilus. Onchodellus acrophilus is similar to O. longus Costa, 1971 but differs in smaller body size (514 – 541 in O. acrophilus, 590 – 610 in O. longus), different body shape (slightly oval O. acrophilus, elongate in O. longulus), different size of anal shield (63 – 65 long, 100 – 105 wide in O. acrophilus, 80 long, 120 wide in O. longus). It differs from O. euparadactylifer Mašán et al, 2013 and O. turcicus Şahin & Özbek, 2018 them because the anterior tip of the peritreme does not reach the base of setae z 1 (in O. turcicus, the tips of the peritreme reach the base of setae z 1; in O. euparadactylifer, the anterior tips of the peritreme extend beyond setae z 1), and in the different number of setae on the soft integument of the idiosoma (13 pairs) (14 pairs in O. turcicus and O. euparadactylifer).	en	Özbek, Hasan Hüseyin (2023): The genus Onchodellus Berlese in Türkiye (Mesostigmata: Pachylaelapidae), with a new record and three new species.

782353158610FF94FF36FC31631DE1D1.taxon	etymology	Etymology. The name of this species refers to the circular metapodal shield on the ventral idiososma of females. Taxonomic notes. Onchodellus circularis differs from most species of the genus by the presence of a specific leaf-like spermatodactyl and a well-developed mediolateral process on the tarsus II of the male, rounded metapodal shields, specifically shortened setae S 1 and S 3, and a smaller number of setae on the soft integument of the idiosoma of the female, but can be compared with species of the O. falcifer group and the O. islandicus group as defined by Mašán (2007). These species groups share the features of a spermatodactyl that is shorter than the length of moveable digit and has 2 – 3 distal branches or is broadened like a leaf. This new species can be compared with the O. islandicus group, but there are important main differences in male and female specimens, as the anterior ends of the peritreme in O. circularis reach the dorsal surface of the shield, whereas in the species of the O. islandicus group, the peritreme is distinctly shortened and the anterior ends do not reach the dorsal surface of the shield. It is also compared with species of the O. falcifer group, especially with male specimens. The male of O. circularis is clearly distinguished from all others by the presence of a larger, well-developed mediolateral process on the tarsus II, which is not present in males of this group. In addition, it differs from O. falcifer (Hirschmann & Krauss, 1965) and O. canariensis (Moraza & Peña, 2005) in having a non-branching, leaf-shaped spermatodactyl (two branches in O. canariensis, three branches in O. falcifer) and differs from O. nidicolens (Koroleva, 1977) and O. brevicrinitus (Hirschmann & Krauss, 1965) by the specific shape of the spermatodactyl, only one process on the genu II and tibia II, and a distinct process on trochanter II. The female specimens are easily distinguished from the others in the genus because they have some specific character states, such as rounded metapodal shields, nine pairs of setae on the soft integument of the idiosoma, punctate surface of the dorsal shield. Ýt can be compared with O. calcaratus (Koroleva, 1977) in that setae J 4 are longer than 50 and setae J 5 are shorter than 16, but they differ in a different J 4 / J 5 ratio (less than 5 in O. circularis, more than 5 in O. calcaratus), the shape of the metapodal shield (not rounded in O. calcaratus), the surface of the dorsal shield with distinct punctation, and diagnostic features in the males, such as the mediolateral process, which is shorter or the same length pl 1 in O. calcaratus, significantly larger and longer than pl 1 in O. circularis, and the anterior part of the holoventral shield (a pair of well-sclerotised ear-like processes in O. circularis (Fig. 22), which are absent in O. calcaratus) (Hirschmann & Krauss, 1965; Koroleva 1977)	en	Özbek, Hasan Hüseyin (2023): The genus Onchodellus Berlese in Türkiye (Mesostigmata: Pachylaelapidae), with a new record and three new species.

782353158612FF9AFF36FCD96168E279.taxon	etymology	Etymology. This species is named after Köse Mountains in Gümüşhane Province, Türkiye, where most specimens were collected. Taxonomic notes. In this study, many females were collected from the study area, but no males, so Onchodellus kosensis sp. nov. was identified and described from females only. Most species in the genus Onchodellus are morphologically very similar, so it is difficult to distinguish them clearly, especially in the absence of males, which have many important diagnostic characters such as spermatodactyls and tarsus II. Nevertheless, O. kosensis can be distinguished from similar species, especially using the classification of Mašán (2007) and the checklist of Mašán & Halliday (2014). Mašán (2007) presented another species group, namely O. strigifer, whose members share some important features, e. g., two pairs of teat-like gland pores (gdS 4, gdZ 1), gdZ 1 in antiaxial position to the line Z 1 – Z 2, S-shaped spermatodacyl of males, and length of setae J 5 less than 20, so O. kosensis seems to be a member of this group and can be compared with these species placed in the European fauna. This new species differs from O. neglectus Mašán, 2007, O. slovacus Mašán, 2007, O. striatifer Mašán, 2007, and O. strigifer (Berlese, 1892) mainly in having 13 pairs of setae on the soft integument of the idiosoma (14 in O. neglectus, 10 in O. slovacus, 12 in O. striatifer, 11 in O. strigifer), and differs from O. tegulifer Mašán, 2007 by longer dorsal setae, J 4 40 – 42, J 5 10 – 14 (J 4 20 – 30, J 5 7 – 13 in O. tegulifer), the shape of the idiosoma, ratio length / width 1.45 – 1.57 (slightly oval in O. kosensis, broadly oval in O. tegulifer, 1.31 – 1.41), differences on chelicerae, ornamented surface of anal shield (anal shield without ornamentation in O. tegulifer), different ornamentation on sternal and genitiventral shields. It could also be comparable with O. bregetovae (Koroleva, 1977), described from Kyrgyzstan, but differing from this species by the presence of seven pairs of setae on the ophistogastric region of the ventral side (eight pairs in O. bregetovae) and by the different ornamentation of the dorsal and ventral shields.	en	Özbek, Hasan Hüseyin (2023): The genus Onchodellus Berlese in Türkiye (Mesostigmata: Pachylaelapidae), with a new record and three new species.
