Table 4 List of potential MOTUs shared by multiple species including their maximum K2P genetic distances within a MOTU (D_M), K2P distance to their nearest MOTU (D_N), and a list of species detected for each MOTU. The nearest-neighbour distance for each MOTU corresponds to the distance to the closest MOTU, disregarding species boundaries
