Taxonomic results are showing that the genus Nanorrhinum is an independent genus, formerly was known as a synonymy of Kickxia section Valvatae. In this paper the genus Nanorrhinum in Iran is revised. Nanorrhinum khuzestanicum and N. baluchestanicum are described as new species from Khuzestan and Baluchestan provinces. These new species are compared with their closest relatives N. chasmophyticum and N. campyloceras that are new combinations. These two combinations are based on Kickxia chasmophytica and Linaria campyloceras respectively.
