Key to the Palaearctic species of Ptiliola View in CoL

1. Smaller, length (labrum to elytral apex) usually less than 0.59 mm; pronotum less transverse, sides more rounded, posterior angles little defined ( Fig. 3 View FIGURES 1 – 6 ). Male: aedeagal sclerites not reaching half the length of the aedeagus, strongly sclerotized ( Figs. 9, 12 View FIGURES 7 – 12 ); metaventrite simple ................... P. brevicollis (Matthews) View in CoL

- Larger, length usually more than 0.59 mm; pronotum more transverse, sides less rounded, somewhat narrowed anteriad ( Figs. 1, 2 View FIGURES 1 – 6 ). Male: aedeagal sclerites larger, more than half the length of the aedeagus, sclerotization weaker ( Figs. 7, 8, 10, 11 View FIGURES 7 – 12 ); metaventrite simple or ornated with a tuft of hairs ( Fig. 4 View FIGURES 1 – 6 ) ...... 2

2. Apical fringe of elytra regular and somewhat wider ( Fig. 5 View FIGURES 1 – 6 ) (this character is best appreciated by transmitted light microscopy). Pronotal reticulation somewhat coarser and less pronounced, especially towards the frontal margin ( Fig. 1 View FIGURES 1 – 6 ); as a result the overall appearance of the pronotum, when studied under reflecting light, more shiny. Male: aedeagus smaller; aedeagal sclerites in ventral view more stout ( Fig. 8 View FIGURES 7 – 12 ); metaventrite smoothly excavated, apically bordered by a distinct tuft of erect hairs ( Fig. 4 View FIGURES 1 – 6 ) .................................... .............................................................................................................................. P. flammifera (Młynarski) View in CoL

- Apical fringe of elytra more narrow, towards the suture fused to form a few brush-shaped extensions ( Fig. 6 View FIGURES 1 – 6 ). Pronotal reticulation somewhat finer and more pronounced ( Fig. 2 View FIGURES 1 – 6 ); as a result the overall appearance more dull. Male: aedeagus larger; aedeagal sclerites in ventral view more slender, somewhat contracted in the middle ( Fig. 7 View FIGURES 7 – 12 ); metaventrite simple ...............................................................................
