Similar species.

Females are most similar to P. paralella . In P. bufo , valvula 3 is clearly not truncate (Fig. 109) in lateral view (slightly truncate in P. paralella ; Fig. 113) and anterior protibial spur is with velum (Fig. 34) (without velum in P. paralella ; Fig. 33). Males are best recognised by examining penis valves (see the Key).

Genetic data.

Based on COI barcode sequences, P. bufo belongs to its own BIN cluster (BOLD:AAU4835). Maximum distance within the BIN is 0.2%. The nearest neighbour to BOLD:AAU4835, diverging by minimum of 6.15%, is BOLD:ABV9415 ( P. parva ). Based on nuclear data (one specimen and NaK), the nearest neighbour is 1.4% different ( P. siskiyouensis ).
