Leuctra fusca fusca ( Linnaeus, 1758)

( Fig. 3A–B )

Macedonia: Valandovo municipality, Belasica Mts , Bašibos, Činarli Stream N of the village, 355 m, N41°19.050’ E22°41.983’, 20.02.2014, leg. DA, LD, TK, DM: 1♂ ( HNHM: PLP4597 ).

This widespread Eurosiberian species is known as an autumnal, hyporhitral-potamal species in most of its range. Early spring imagoes were reported only from the Iberian Peninsula in Europe, the present data from February is the first non-autumnal report from the Balkans. The single male found above Bašibos shows no notable morphological difference from autumnal specimens previously collected in Macedonia.
