Thaumatomonadidae

Biciliated cells with ventral pseudopodia, long ventral posterior pointing cilium used for gliding on surfaces unlike Peregriniidae (see below), and a much shorter anterior cilium, which is naked (Thaumatomonas, Allas) or with small scales (Reckertia, Thaumatomastix); siliceous scales formed in vesicles attached to mitochondria cover the rigid cell surface except for a ventral zone that emits pseudopodia for feeding; unlike Peregriniidae, do not transform completely into an amoeba; all have oval or triangular two-tiered body scales, with an upper plate bearing species-specific perforations supported at the oval ends or triangle corners by discrete struts, unlike Gyromitus; upper plate lacks central cleft with inrolled sides, unlike Peregrinia; Thaumatomastix only additionally has long spine scales with near-circular or rounded triangular bases. Allas, Hyaloselene, Reckertia, Thaumatomonas, Thaumatomastix.

Peregriniidae

With only oval two-tiered body scales and no ciliary scales or spine scales; scales either symmetric ovals with heavily out-turned upper and lower rims as in Gyromitus or asymmetric ovals with concave to flat lower surface and convex upper surface with rims more strongly laterally inrolled than at the ends as in Peregrinia; in contrast to Thaumatomonas, ciliary pit apical not subapical and ventral, or cells so amoeboid as to lack defined shape; cilia not clearly differentiated into anterior and posterior; unlike Thaumatomonadidae no evidence for ciliary gliding; locomotion by swimming or slow amoeboid creeping. Gyromitus, Peregrinia
