Figs 18-20 , 34 Material . Holotype ♂ , Burmese amber, NIGP 173716 , ( NIGP ). Etymology. The species is named in memory of Andrzej Skalski, who published the first record of a lophocoronid specimen from Asia ( Skalski 1979 ), an interpretation later considered very tentative by Kristensen and Skalski (1998) . Preservation. Completely preserved in a nearly rectangular piece of amber, wings somewhat spread, but overlapping, head, legs and postabdomen clearly visible (Fig. 34 ). Description . Length of forewings 4.1 mm, antennae dark brown, with 29 flagellomeres; wing venation (Fig. 18 ) with cross-veins r1-ac and m-cu present, hindwings without accessory- (ac) and median cell (mc). Male genitalia (Figs 19 , 20 ): segment IX with short, median prolongation in dorsal view, presumed median plate below this prolongation bilobed; rod-like spine on ventral apex of valvae long and straight, apical margin of valvae with denticules, and some additional denticules before margins; basal spikes of valvae paired, longer as length of valvae, sitting on elongate papillae from median side of valvae, a third median pair of bristles present, shorter than basal spikes. Phallus not visible.
