Microchlamyiidae fam. nov.

The definition of the family Microcoryciidae de Saedeleer, 1934 as given by Loeblich & Tappin (1964) - 'test membranous, in part rigid or semi-rigid, thinning and becoming more pliable toward variously shaped aperture, one or more nuclei', includes genera with external covering more closely related to those of Cochliopodium and Gocevia than that of Microchlamys. However, the description of these genera are based on optical studies and the exact nature of their 'tests' must await fine structure studies. It is apparent from this study that the genus Microchlamys has a well defined shell with features distinctly different from any already described to warrant its inclusion in a new family, as defined below:

Microchlamyiidae fam. nov.

Test proteinaceous, flexible or rigid; cytoplasm enclosed in membrane with single aperture, attached to main test; nucleus central.
