Rovnoscydmus sp. specimen 10 ( Figs 23 , 165–166 ) Material studied. Late Eocene of Europe , Rovno amber: sex unknown; inclusion in elongate, irregular pyramid of amber 24.5 mm long ( Fig. 23 ), collection number K-15548 ( SIZK ). This specimen is preserved in cloudy and turbid amber and most of the important characters are not visible under a light microscope. However, its body form seems similar to that of Rovnoscydmus , and measurements support this determination. Only incomplete measurements can be used to characterize this inclusion: BL 0.98 mm ; HL 0.18 mm ; AnL 0.48 mm ; PL 0.30 mm ; EL 0.50 mm .
