Villaria marinduquensis Arriola & Alejandro (Octotropideae, Rubiaceae) is herein described and illustrated as a new species from Marinduque, Luzon, Philippines. The uniflorous inflorescences and infundibuliform calyx tube of V. marinduquensis resemble those of V. acutifolia and V. uniflora; however, the features of bracts, calyces and corolla in the new species differ from those in the two afore-mentioned species. Villaria marinduquensis is distinguished from all of its congeners by having a tubular corolla tube. An identification key to the Villaria species is provided.
