Type species: Reticuloceras superbilingue Bisat, 1924, p. 51, 117 [OD].

A:   Conch form like Reticuloceras.
B-F: Ornamentation with strong ventrolateral salient and two ventrolateral furrows on each side; longitudinal lirae weak, if
present.
 
[Nassichuk, 1975, p.119: The conch of Bilinguites is subdiscoidal and moderately involute at maturity; W/D varies from about 40 to 50 per cent and approximately 30 per cent. The mature venter is narrowly rounded typically, but on some species it is either subangular or angular. Two parallel, longitudinal grooves with rounded bottoms occur on the ventrolateral flanks; grooves are separated from each other by a rounded ridge. Strongly developed growth lines form a prominent tongue- (lingua) shaped projetion (salient) between the ventrolateral grooves and correponding deep sinuses across the venter and flanks. Relatively weak longitudinal lirae may be occur across the venter and flanks.
The external suture is characterized by elongate, pointed ventral prongs, the sides of which are essentially parallel with the ventral axis. The first lateral saddle broad and evenly rounded and the first lateral lobe is more or less V-shaped].
