The allogromiid foraminiferan protists comprise a series of basal clades that include naked, organicwalled, and monothalamous agglutinated taxa [1-2]. Representatives are known from marginal marine settings to the deep sea, and in selected freshwater settings and terrestrial soils [3] . Molecular studies [4] [5] have shown that the biodiversity of allogromiids is considerably higher than that recognized using traditional collecting methods, and as a result we know little about the adaptations and modes of life of this group.
