This species is a small tree growing in dry forest on calcareous substrates. Both morphological and molecular data support C. calcareus sp. nov. as a new species closely related to C. redolens, another dry forest taxon from northern Venezuela. We provide illustrations, a distribution map and suggestions for species conservation status. The new species along with Croton draco are the only known representatives of C. section Cyclostigma occurring in Mexico UR - https://drive.google.com/file/d/1l-PWi99va1C2Zojx9WwRwFAO9XDo6r53/view?usp=drivesdk ER -
