Abstract
Re-examination of the type material of six species described by Brues from the Baltic amber in the genus Cryptoserphus revealed that none of them belong to this genus but represent four species within other extant genera, i.e. Fustiserphus pinorum (Brues, 1940) comb. nov., Mischoserphus gracilis (Brues, 1940) comb. nov., Oxyserphus obsolescens (Brues, 1940) comb. nov., and O. hamiferus (Brues, 1940) comb. nov. Two other species (Cryptoserphus tertiarius and C. succinalis) described by Brues and Cryptoserphus koggeauxillarius described by Szabo & Oehlke (1986) are synonymised under O. obsolescens. All species are redescribed and illustrated.References
