Description
Test planispiral discoidal to biconcave, slightly asymmetrical, early 1 or 2 whorls involute, later 2 to 4 whorls becoming evolute, with whorls rapidly increasing in thickness, leaving broad, deep umbilicus; septa simple; wall homogeneous in structure, minor supplementary deposits (pseudochomata); single aperture. [Semillovella was originally regarded as transitional between Millerella and Novella, but because of the simple wall structure and single aperture it is here transferred to the Endothyrinae and elevated to generic status.]
