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).

Host plants.

Vaccinium myrtillus L. (ex ovo rearing experiments by VV).

Rearing notes.

Ovipositing experiment no. 3/1986: Finland, South Häme, Janakkala, Kalpalinna. On 22.V.1986 one captured female laid 5 eggs in pockets near leaf-margin on underside of the leaves of Vaccinium myrtillus . Larvae hatched on 27-28.V.1986, 5 larval instars were observed. Larvae eat margins of shoots and margins of leaves near their bases. Last instar was more than 16 days long. No “extra” moult after feeding. Larvae were put in alcohol on 27.VI.1986.

Distribution and material examined.

Palaearctic. Specimens studied are from Czech Republic, Finland, and Germany.
