Two unispecific Andean genera are described as new to science in the tribe Spathicarpeae (Araceae) and illustrated, based on two species formerly placed in the genus Asterostigma. The genus Incarum is erected to accommodate A. pavonii that occurs in Andean Peru, Bolivia and Ecuador, and the new combination Incarum pavonii is validated. The genus Croatiella is erected to accommodate A. integrifolium from Ecuador and the new combination Croatiella integrifolia is validated. Incarum is considered related to the Andean genera Gorgonidium and Spathantheum, whereas Croatiella seems to be an isolated lineage within the core Spathicarpeae. The arguments to support these new genera come from cpDNA sequence data, as well as from biogeographical and morphological aspects.
