We name the new species Claderia leontocampus Niissalo. Plants of the new species have been collected or recorded in Sumatra, Peninsular Malaysia and possibly Peninsular Thailand. We carried out population genetics analyses to show distinction between the new species and Claderia viridiflora. The two species occur in the same habitat in Singapore. We used phylogenetic analyses to find out the phylogenetic position of Claderia within Orchidaceae; the genus is here considered to belong to subfamily Epidendroideae Kostel., tribe Epidendreae Lindl., subtribe Claderiinae Szlach.
