Number of specimens:>30
Diagnosis. “Species with segminate elements that have a length:height ratio of 2.5–3:1, and commonly 15–18 subequal, moderately fused denticles that are increasingly reclined toward the posterior end where 3–5 small, low denticles occur on a short, variably inturned process. Te posterior edge of the blade is moderately reclined. In basal outline, the basal cavity is elliptical, tapers in both anterior and posterior directions, and is strongly asymmetrical in specimens with an inturned posterior process.” (Orchard, 1995).
Remarks. Tis species may be slightly younger than the closely related Tr. symmetricus.
