Table 3. Results from ABGD test of Coryphellidae representatives applying different parameters. Species identity is interpreted as confirmed (yes) when delimitation is supported in the initial partition with high P -value (> 0.0032), as ‘partly’ for groups recovered in the recursive partition, and as ‘no’ when two distinct groups were not recovered (i.e. one, three or more groups)
