Tarsus with a spur-like seta p11 and small opposite mediolateral apophysal spur; apophysal spur distinctly shorter than pl1 (Fig. 9).</p><p>Etymology. The species is named after Anatolia, a region in Türkiye where it was first discovered.</p><p>Remarks: The species Onchodellus anatolicus sp. nov. belongs to the O. strigifer group, which was established by Mašán (2007) based on the presence of two pairs of slit-like gland pores (gdZ1, gdS4), the structure of the spermatodactyl, and the length of the J5 seta. It can be compared to the seven previously described species in this group (Özbek &amp; Halliday, 2024).</p><p>Onchodellus anatolicus sp. nov. can be easily distinguished from most species of this group by the number of setae on the soft integument, which varies among species as follows: 12 pairs in O. anatolicus and O. striatifer; 11 pairs in O. strigifer (Berlese, 1892) and O. montanus Şahin &amp; Özbek, 2018; 14 pairs in O. neglectus Mašán, 2007; 10 pairs in O. slovacus Mašán, 2007; and 13 pairs in O. tegulifer Mašán, 2007, O. kosensis Özbek, 2023, and O. marginatus Özbek &amp; Halliday, 2024 . Although O. anatolicus shares the same number of setae with O. striatifer Mašán, 2007, it differs in several morphological features, including the shape of the idiosoma, the ornamentation of the dorsal shield, the significantly longer J5 setae (16–20 long in O. anatolicus; 8–13 in O. striatifer), and a longer spermatodactyl in males (185–190 O. anatolicus; 120–140 in O. striatifer).</p></div>	https://treatment.plazi.org/id/330887C1FFADC902FF3DFD44FC2BFFD5	Public Domain	No known copyright restrictions apply.

Male.</p><p>Dorsum. Dorsal shield 490–530 long 290–305 wide at the level widest point (length/width 1.37–1.52), suboval shaped, setae J4 60–65, J5 microsetae. Ornamentation and dorsal chaetotaxy as for female.</p><p>Venter. Holoventral shield 415–420 long, 265–280 wide at the level coxae II, ornamented with reticulate pattern and bearing nine pairs of setae (plus three circum-anal setae around anus). Dorso-lateral and ophisthogastric soft integument with 12 pairs of setae.</p><p>Gnathosomal structures. Moveable digit of chelicera 46 long, with a subdistal tooth and terminal hook, spermatodactyl 110–115 long, more than twice as long (2.45) as movable digit, narrowing towards the distal part and basally with a well-developed triangular process (Fig. 21).

Later, Özbek and Mašán (2018) provided additional morphological insights based on two female specimens from Tunceli province in Türkiye, reporting the presence of 12 setae on genu I (with pd3 absent) and fifteen pairs of setae on the soft integument (seven pairs of marginal setae and eight pairs of opisthogastric setae). Furthermore, Costa (1971) did not mention the tubes of the spermathecal apparatus in his original description, and Özbek &amp; Mašán (2018) hypothesized that these structures are likely unsclerotized, rudimentary, or absent.</p><p>In the present study, ten females and three males specimens of P. evansi were collected from the valley. These specimens were examined in detail, photographed, and measured, yielding several new and significant findings for the species. These findings are as follows: (1) the tubes of the spermathecal apparatus are clearly visible, associated with the posterior margin of coxae IV, and appear short and tubular; (2) setae Jv 2 are predominantly positioned on the posterior margin of the genitiventral shield, although in one of the newly collected specimens and two previously collected specimens from Tunceli province, they are located on the soft integument; (3) setae z1 are distinctly longer than j1; (4) genu I and tibia I of the males exhibit distally narrowed processes; and (5) more detailed morphometric data and differential interference contrast (DIC) images are provided to further elucidate the species‘ morphological characteristics.</p></div>	https://treatment.plazi.org/id/330887C1FFABC90FFF3DFF3CFEF5FA97	Public Domain	No known copyright restrictions apply.
