Thaumalea rumanica is a member of the family Thaumaleidae and it has been described from a few localities surrounding Băile Herculane, south-west Romania. Since its discovery, no further data were published on this endemic species of restricted range from the Carpathian region. On August 18, 2020 a single male specimen was collected at Poiana Mărului, in Olteana valley, south-west Romania, at 720 m altitude by the present authors, which is farther north from its typical location. This new finding suggests a larger distribution of the species in the Southern Carpathians. Based on our recent faunistic survey, a new species, Thaumalea remota was added to the Thaumaleidae fauna of Romania, with a revised checklist of the family, based on both personal and recent literature data.
