THE CONCINNUM GROUP

Diagnosis: Species of this group are similar to those of the quaesitum group in many features but can be distinguished by the symmetrical hypandrium in the male ( Fig. 32C ). The female is known only for T. concinnum , and it differs from females of the quaesitum group in the asymmetrical internal plate with anterior region partly pigmented ( Fig. 33C ).
