ABSTRACT. Europs makarovi sp.n. is described from Mexican amber (Chiapas, Simojovel). This new species seems similar to the extant E. cognatus Sharp, 1900 and E. sulcicollis Bousquet, 2003, but differs from them because of the relatively longer head, and much stronger puncturation of the head and pronotum. The new species of Europs is distinguished from all contemporary species of the genus by a combination of features: uniformly dark body colour; relatively long head (the ratio of head length to length of pronotum is 0.76); very coarse head puncturation; disc of pronotum with 2 longitudinal, more or less parallel, punctate grooves, forming a lyre figure; a wide impunctate medial area between grooves (as wide as diameters of 7–8 punctures); not rounded but triangularly produced coxal line in the first ventrite; proportionally longer elytra (LE/LP > 1.98).
KEY WORDS: Coleoptera, Monotomidae, Europs, Miocene, Mexican amber.
