The silhavyi group

Diagnosis

Males of this group can be recognized by having the apophysis at the base of the embolus curved and laminar ( Figs 9C–D , 22C , 23B , 26A–B ); the sperm duct forming an inverted ‘S-shape’ in the male palp not expanded, with secondary looping in the middle of the tegulum ( Figs 9A , 22C , 25C ). The females can be recognized by having the atrium wide and copulatory ducts large in the anterior region ( Figs 22G , 26D , 33D–F ).
