Diagnosis
ReferenceDiagnosis
C. B. Skovsted et al. 2014Species of Tannuolina characterized by the presence of both narrowly compressed, bilaterally symmetrical sellate sclerites and asymmetrical, openly coiled sellate sclerites with deep internal cavity, and a shallow sella and subcentral keel on the sellate side. Sellate sclerites with open perforations concentrated to both lateral margins and to a narrow zone surrounding the lateral margin on both the duplicatural and sellate sides. Mitral sclerites with convex decrescent side, a shallow external furrow and a low internal carina on the carinate side and poorly differentiated obcarinate and acrescent sides. Obcarinate/acrescent sides with multiple, externally open perforations and decrescent side with a fine cancellate surface ornament. A single perforation or a small group of large perforations are located close to boundary of the initial growth increment, at the junction of the decrescent and carinate sides.
