Praebythoceratina trinodosa
The generic identification follows Becker (1990), while the specific follows Alexander (1934). Despite being poorly preserved, the holotype of Praebythoceratina trinodosa (Alexander, 1934) comb. nov. presents typical morphological traits that are not common in other Early Cretaceous bythocytherid species a postero-dorsal tubercle over the lateral u-shaped inflation and the presence of reticulate ornamentation at the central area that slightly fades along adjacent areas but observable in the present specimens. Compared to P. amsittenensis comb. nov., P. trinodosa comb. nov. is more slender in lateral view and presents more developed antero-dorsal and postero-dorsal tubercles.
