Fig. 17 f-j

Description. This species is quite similar to T. pontica with the difference that males are more elongated and display an almost parallel running dorsal-and ventral margin. Also, the posterior end is more rounded and without the distinct shoulder. The ornamentation is the same, but the ventral crest in general appears much shorter than in T. pontica . Dimension: L = 0,28 – 0,93 mm, H = 0,17 – 0,49 mm, the minimum sizes include juveniles too.
