Clade Pterovianaida View in CoL + Thaumamannia

The clade Pterovianaida + Thaumamannia is supported by one synapomorphy ‘head position declined’ (char 1, state 1 or 1-1 – Fig. 2B View Figure 2 ) and one homoplastic synapomorphy, ‘the large scales on the anterior region of the hemelytral margins’ (25-2). Internally to this clade, the genus Pterovianaida is recovered monophyletic, supported by two synapomorphies and one homoplastic synapomorphy: abundant head setae (0-2 – Fig. 3C View Figure 3 ), presence of a paranota constriction (18-1 – Fig. 4B View Figure 4 ) and frons at same height as clypeus (8-0), respectively. Thaumamannia , including its two new species, is also found to be monophyletic, supported by one synapomorphy and two homoplastic synapomorphies (presence of large scales on paranota borders, 17-2 – Fig. 5C View Figure 5 ; scutellum narrower than half of the maximal width of the head, 15-0, and scent gland peritreme with a shorter posterior branch than the upper part of the anterior branch, 23-1, as the two homoplastic synapomorphies). Thaumamannia insolita is found to be the sister-group to all remaining congeners, supported by one synapomorphy: pronotum more than two times wider than long (14-1 – Fig. 6B View Figure 6 ). Thaumamannia urucuana and T. manni are recovered as one clade, the sister-group to T. vanderdrifti based on two synapomorphies: posterior region of the bucculae round, 6-0 – Fig. 7A View Figure 7 , and posterior region of the bucculae wider than anterior half (7-1).
