Neotropical species of the scale insect genus Rhizoecus Künckel d'Herculais (Hemiptera: Coccomorpha: Rhizoecidae) found in soil sample material of the Hungarian Natural History Museum were studied. Two new Rhizoecus species, Rhizoecus kontschani Kaydan and Konczné Benedicty sp. n., and Rhizoecus granaradewillinkae Kaydan and Szita sp. n., are described and illustrated based on the adult females. Also, the adult females of Rhizoecus keysensis Hambleton and Rhizoecus pseudocacticans Hambleton are illustrated. An identification key and new additional locality records for the currently known Rhizoecus species are provided.
