Mustelicosa dimidiata (Thorell, 1875) ( fig. 9 )

M a t e r i a l e x a m i n e d. Kyiv: Kozyn , open dry pine forest on sandy soil, pitfall traps, 21.06‒ 9.07.2019, 1 Ơ, V. Yanul leg ; Rzhyshchiv Technical Schoolfor Building , old abandoned field, meadow steppe on sandy soil on a slope, pitfall traps, 8.09‒ 14.10.2021, 1 ♀ (N. Polchaninova & O. Vasylyuk leg.) .

Distribution. East European–Central Asian subboreal species; its westernmost known localities were in Rivne and Mykolaiv Regions of Ukraine ( Polchaninova et al., 2017; Hirna et al., 2020).

In the western part of its range, the species has patchy distribution being associated mainly with grasslands and open pine forests on sandy soils. Its eastern boundary is unclear. According to Yu. Marusik (2018), the species recorded from China, Kazakhstan and Korea as A. albostriata (Grube, 1861) are likely to refer to other species, related to Mustelicosa dimidiata . Nevertheless, there are no recent studies to support this assumption (WSC, 2022).
