We measured 206 male specimens from the British Coleoptera collection of the BMNH (Natural History Museum, London). All 206 specimens were measured by the same person (J.J.S.); 106 Bledius spectabilis Kraatz, 1857, 54 B. frisius Lohse, 1978 and 46 B. tricornis (Herbst, 1784). Measurements were obtained from images using the free software ImageJ (Schneider et al. 2012). Measurements were taken as straight-line distances between two points. Due to the pronotal horns being fused to the anterior margin of the pronotum, horn length was taken from the tip of the horn to the posterior margin of the pronotum. Width of the pronotum was taken at the widest point as an indication of overall body size
