Similar species.

Species limits in the carinata group are still unclear.

Genetic data.

Based on COI barcode sequences, specimens of the carinata group are divided between four BIN clusters (BOLD:AAF4995, BOLD:ABU8603, BOLD:ACL1744, BOLD:ACL1745), which form a monophyletic group (Fig. 5). Minimal distances between these clusters are 1.2%-4.48%. Because of unresolved taxonomy, it is not yet clear how different species are divided among these BIN clusters. Based on nuclear data, maximum divergence within the group is 2.2% (based on ten specimens and TPI) and the nearest neighbour is 1.5% ( P. pseudocoactula , both genes combined) or 1.0% different ( P. wesmaeli , only NaK).
