Diagnosis
ReferenceDiagnosis
A. Kouchinsky et al. 2009Selindeochrea species characterised by almost straight or slightly twisted internal moulds with rounded lobes and flattened depressions in between them.

Internal moulds slightly twisted clockwise, with triangular tri-lobate cross-sections (Fig. 48F, H)). Grooves (depressions) between extended lobes are wide and shallow with a flattened middle part (Fig. 48F–H). There is a median narrow ridge on the flattened depressions between the lobes (Fig. 48B, D–E). In the flattened depressions, growth lines are arched and pointed at an acute angle towards the aperture (Fig. 48B, E). In preserved thecae, the lobes are extended distally by prominent keels (Fig. 48C, H). The keels undulate, with folds running towards the aperture at ca. 45˚(Fig. 48D–E). Lobes of the internal moulds are rounded or somewhat swelled and almost straight (Fig. 48F).
