Abstract

A new antiarch species Microbrachius kedoae n. sp. is described from the Middle Devonian (Givetian) of Belarus. The species is based on isolated dermal plates recovered from a borehole near the village of Gavrilchitsy about 25 km southwest of the city of Soligorsk. Microbrachius kedoae compares well to the type species Microbrachius dicki from Scotland, but differs from this and all other Microbrachius species in the mixilateral plate being overlapped by the anterior median dorsal plate. The presence of Microbrachius species of the same age in Scotland and Belarus strengthens the argument of faunal connections between the two areas in the Middle Devonian.
