Table 2.

Intra- and inter-species pairwise genetic distances. Ranges of minimum to maximum distances are indicated (in percentage). For instance, within Onchidium typhae, individual sequences are between 0% to 0.5% divergent, and individual sequences between Onchidium stuxbergi and Onchidium typhae are minimally 21.7% and maximally 26.2% divergent.

Onchidium stuxbergi	21.7–26.2	0.0–5.1
Onchidium reevesii	26.9–28.3	15.0–18.1	0.0–0.7
