1971  Mirilentia Ruzhentsev & Bogoslovskaia: 328.

Type species: Mirilentia uberta Ruzhentsev & Bogoslovskaia, 1971, p. 328 [OD].

A:   Conch form small, thick-discoidal, with narrowly rounded, almost oxycone ventral side; umbilicus narrow, last half whorl
with wide umbilicus.
F:   Faint longitudinal lirae may disappear on later stages.
D:   3 - 4 constrictions, only on young stages, with lateral sinus and ventral salient.
G:   Ventral lobe narrow, rounded, with very low median saddle. Adventitious and lateral lobes broadly rounded.

[Ruzhentsev & Bogoslovskaia, 1971, p.328: Small conch, sphaericone in young individuals, subdiscoidal in the
terminal stage of growth.  Whorls are evolute in the beginning and become very involute only at the end of growth.  
The umbilicus changes with age from moderately to very tight, but on the last half-whorl it sharply widens and the
umbilical wall disappears.  Sculpture consists of thin lirae which disappear on the pre-umbilical zone or on the
whole surface with progressing phylogenetical development.  Three to four constrictons per whorl only exist in
young specimens and later disappear.  They are developed mostly on the sides and form a significant ventral
salient and a weak lateral sinus.  Ventral lobe quite thin, with somewhat parting sides, and is very weakly
segmented.  Base of lateral lobe sharp-ended or widely rounded.]
