Yap, Caroline Islands


A fairly large, rather distinctive-looking taxon that was in the past placed in a monotypic genus, Kubaryum, then subsequently transferred to Rukia, where sometimes retained; however, DNA-DNA hybridization data indicate that it belongs in present genus. Possibly most closely related to Z. semperi. Monotypic.


Yap, in W Caroline Is.
