Abstract
This paper describes the morphology of two new species of Mastogloia identified during a survey of the marine benthic diatom flora of Guam. Mastogloia parlibellioides sp. nov., classified in the section Decussatae, is distinctive in the combination of its valve shape and stria pattern reminiscent of Parlibellus, as well as the presence of rudimentary division walls extending from the free margin to the middle of each partectum. Mastogloia lyra sp. nov., classified in the section Sulcatae, subgroup 2, has internal lyre-shaped lateral sterna and partecta that are displaced toward the midline of the valve by a siliceous flange, which shows oblique partectal ducts. The descriptions of these two new species increase the knowledge base of biodiversity in a Pacific Ocean Mastogloia hotspot.
