The last revision of the sub-genus Drimeotus s.s. Miller, 1856 of Padurea Craiului mountains (Transylvania, Romania) was realized by Jeannel in 1930. Later, several authors modified the taxonomy. New discovered populations, from this area, could not been integrated in the group by using the external morphological features of the existant Jeannel ‘s dichotomous key. Therefore, the work insists on less variable criteria in the population, such as the morphology of the male copulatory organ and its internal structures. The obtained results are consistent with the subgenus biogeography. Two new species are also described: Drimeotus racovitai and D. osoiensis and a new dichotomous key is proposed.
