Remarks . When describing M. russica , Smolis et al . (2012) stated that seta M present [on], setae A3 and A6 absent (p. 150) from the tibiotarsi of this species. However, in most described cases in Poduromorpha (see, for instance, Fjellberg, 1990 , 1991 ) the reduction of tibiotarsal setae begins with the loss of seta M and one or both of the inner setae of distal whorl, i.e. A4 and/or A5. As Fjellberg (1998 , p. 75) wrote, the tibiotarsi [in M. pygmaea ] with 18–18–17 setae, seta M absent . … Juveniles and subadults may lack one or more of tibiotarsal setae T3, T4, A4, A5. Thus, the absence of setae A3 and A6 postulated for M. russica seems doubtful. Instead we believe that actually this species lacks setae M and A4, which is more usual to the genus. The species appears to be rather widespread in the region under study. Its types originated from Primorskyi Kray , Khasan Area , Barabash [ 43°11' N 131°29' E ] , i.e. the southernmost part of Primorye , whereas one of the localities where we found this species ( Zeya State Nature Reserve , Amur Region ) is located more than 1200 km to the north-north-west .
