Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. Fehse and J. Grego 2012 | Only T. avellanoides has a similar developed dorsal sulcus but the new species is also distinguished by its smaller size (T. avellanoides 16–24 mm v. T. felixlorenzi 10–15 mm), the shape of the aperture, the stronger, different shaped labrum, more close-set ribs and the more elongated anterior terminal. |
