The male of T. ferdowsii differs from those of the congeners by the arms of radix relatively short, blunt, and of equal size (vs long, pointed, of different sizes) (see Figures 9 , 15, 17, 19 ). Description. For male, see Zamani et al . (2017) and Fomichev (2022) . The female is currently unknown (see ‘Comments’). Comments. Zamani and Marusik (2023) found that the females described and listed as belonging to this species by Zamani et al . (2017) were mismatched. These specimens were described as a separate species, Oecobius melanocephalus Zamani and Marusik, 2023 . Following this, the specimen illustrated in fig. 3A of Zamani and Bosselaers (2020) belongs to O. melanocephalus . Distribution. Known from Razavi Khorasan Province in north-eastern Iran and Mangystau and Turkistan regions in south-western and southern Kazakhstan ( Zamani et al . 2017 ; Fomichev 2022 ; present study). It is possible that the doubtful records of T. tadzhikus from Turkmenistan ( Mikhailov and Fet 1994 ) belong to this species ( Figure 35 ).
