Duvalius beshkovi Coiffait, 1970

Type material. Bulgaria, Osogovo Mt., Mecha Dupka Cave, 720 m a.s.l., near the Stradalovo Village, 27.II.1969, under stone, leg. P. Beron, ♂ holotype (MNHP).

Material studied. Republic of Macedonia, Osogovo Mt., Ruen Peak, 2252m, mountain pasture, under boulders, 13.06.2009, 1 s., leg. S. Hristovski (cSH).

Distribution. 83.

Notes. New species for the fauna of Macedonia. There are morphologic differences between the specimens from the Ruen Peak and the holotype which was found in a cave in the eastern part of the Osogovo Mt. (Bulgaria). Only one male specimen was collected on Ruen Peak. The comparison of the male genitalia between the last specimen and the holotype showed greater similarity than their external morphology suggested. Larger series of specimens is needed to clarify this problem.
