Discussion. Vitali & Rezbanyai­Reser (2003) synomymized Plectromerus distinctus (Cameron) with P. serratus (Cameron) . The type specimens (BMNH) of both species ( Figs. 1a–b ) were examined carefully and differences between them suggested two species instead of one. The two species are very similar but can be distinguished by the following: P. distinctus has long, suberect hairs on the elytra and granulose punctures on the pronotum ( Fig. 1c ), whereas P. serratus lacks the hairs and granules and has microsculpturing on the pronotum ( Fig. 1d ).
