Dinocheirus panzeri (C.L. Koch, 1837) ( Figures 2 and 3 )

4: Moscow, urban area, 23 June 1997, 1 female, 2 deutonymphs, nest of F. hypoleuca ; 5 June 2008, 1 female, nest of S. vulgaris ; 6 : Moscow, Kuskovo Park , July 2008, 6 males, 4 females, 1 tritonymph, nest of Passer montanus ; 8 : Moscow, Terletskiy Park Forest , June 2008, 1 male, 1 female, 1 tritonymph, 2 deutonymphs, nest of T. pilaris ; 6 August 2008, 1 female, 7 protonymphs, nest of Certhia familiaris ; 2 September 2010, 1 tritonymph, nest of T. pilaris .

Remarks: First record for Russia. The species is widespread in Europe ( Harvey, 2013). Georgia represents the closest country of the species distribution to the current findings ( Kobakhidze, 1963). Dinocheirus panzeri has frequently been reported from tree cavities ( Šťáhlavský, 2001; Drogla and Lippold, 2004; Christophoryová et al., 2017) and its occurrence in bird nests is also commonly known ( Turienzo et al., 2010).
