Diagnosis. T. unispina is close to T. crocea on both external and male genitalic features. It differs from the latter by the slightly sclerotized gnathos, the dorsal part of which is narrower and covered with long hairs; the ventral plate is less broad and its process is less extended than in T. crocea ; the anellus is narrower than in T. crocea . For comparison with T. subunispina see under the next species.
