Diagnosis. Body length 2.6–2.8 mm. Black, with two reddish spots on each elytron: basal spot rather large and elongate, apical spot more rounded. Pronotum subconvex, sides somewhat oblique, posterior angles obtuse and rounded. Elytra with stria I reaching apex, stria II moderately impressed, stria III slightly impressed, stria IV visible, striae V–VII obsolete, stria VIII deeply impressed but widely interrupted in middle.

Comments on classification. SCIAKY & VIGNA TAGLIANTI (2003) consider Paratachys Casey, 1918 a valid genus based on differences in the recurrent stria and the eighth stria, with Polyderus Motschulsky, 1862 and Tachys Dejean, 1821 .

Distribution. Known from Iran, North Korea, Thailand, China, Africa and Oriental Region. First record from Socotra Island.
