FIGURE 4: Character 6. Comparative length of os ectethmoidale ventral expansion: (A) Willisornis poecilinotus (MPEG 2702), state 0—longer than dorsal expansion; (B) Hylopezus macularius (MPEG 2299), state 1—equal to dorsal expansion; (C) Myrmornis torquata (MPEG 2734), state 2—shorter than dorsal expansion. Black lines evidence length difference between dorsal (de) and ventral (ve) expansions. Frontal view. Scale bar: 3 mm.
