Tupirinna trilineata group

Diagnosis. Males of the trilineata group are characterized by the weakly developed ventral lobe of the retrolateral tibial apophysis, and by the presence of a dorsal lobe ( Figs 14F , 15B, 15F , 16B ). Females can be recognized by the undeveloped posterior vulval plate, sclerotized copulatory pouch, and the presence of small secondary spermathecae (except in T. trilineata and T. ibiapaba sp. nov., in which it is absent) ( Figs. 15D , 16F , 17F ).
