The riveti group

Diagnosis

Males of this group resemble those of the silhavyi group by the apophysis at the base of the embolus, but differ by presenting an apophysis at the base of the embolus that is short and conical (Fig. 12B–C); the sperm ducts are ‘U-shaped’ in the male palp when it is not expanded (Figs 9B, 10C). The females can be recognized by the short atrium, presenting a septum or not, and copulatory ducts narrow (Figs 10F–G, 11F, 15F–G).
