Diagnosis

T. klemmi has regularly narrow-conical shells (2.2 mm) with blunt apex, deep suture and widely spaced coarse ribs on shell surface, rounded callous irregular-oval shaped aperture and closed umbilicus. Lateral labral profile straight and columellar labrum only weakly sinuated. Protoconch surface overall covered by regular and deep pitting.

Distribution

T. klemmi is known from Vrelo “Stenjevac” and Vrelo “Baja” in Vrgorsko Polje (20 m a.s.l.) near Vrgorac and from Vrelo “Kutac” and other springs around Baćinska Lakes (0.8 m a.s.l.) near Ploče. The aquifer also receives its water from Rastok Polje (72 m a.s.l.).

Remark s

Travunijana klemmi represents the northernmost species of the genus. Its shell morphology has some features of the genus Belgrandia (e.g., Belgrandia torifera Schütt, 1961 ) known from the region, however its shell is more conical and lacks the typical callous varix near the labrum.
