Pachymerium tabacarui is a species of centipede in Geophilidae family that is endemic to Romania.

[1] The original description of this species is based on a female specimen from the Carpathians measuring 15 mm in length with 53 pairs of legs.

[2][3] Some authorities consider this description consistent with a juvenile specimen of P. ferrugineum and therefore deem P. tabacarui to be a junior synonym of that species.

[3][4] A more recent review of this description suggests that P. tabacarui is a junior synonym of Geophilus flavus rather than P.

[5] Extensive investigations in the Carpathian region have failed to collect any more specimens.
