Euboeus tenebricosus species-group

This group unites many species from the Balkans in the west to Turkmen-Khorasan mountains in the east. Species representing this group are characterized by matt dorsal side of the body, coarse and dense puncturation of pronotum and strong long setae on the apical part of the abdominal ventrite 5. Usually, representatives of this group are associated with forests, but some species are geobiontic. All Iranian taxa of the group are inhabitants of woodlands, except for probably Euboeus corrugosus .
