New records. CZECH REPUBLIC: BOHEMIA: Krkonoše Mts., Labská Bouda, 25.vii.–15.viii.2007, 2 JJ, M. Barták leg. (Malaise trap), Pančavská louka, 16.–17.vi.2005, 8 JJ, M. Barták leg. SLOVAKIA: Belianské Tatry Mts., Tatranská Javorina, Široká dolina valley, 1100 m, 17.viii.–8.ix.1992, 3 JJ, M. Kozánek leg. (Malaise trap).

Variation. Claustropyga refrigerata is a very variable species concerning the position and number of the subapical-mesal megasetae ( Figs 13–14 , Table 1). In normal cases there is a line of 3–4 megasetae at the ventral edging of the gonostylus and 2–3 megasetae on a mesial ridge which extends from the base of the gonostylus to the apical tooth ( Figs 14–15 ).

Distribution. This species has hitherto been known from Austria, Finland, Germany, Norway, and Sweden ( HELLER & MENZEL 2017). These are the first records from both the Czech Republic and Slovakia.
