Pristiphora albilabris (Boheman, 1852)  Figs 210, 238

Nematus (Nematus) albilabris  Dahlbom, 1835b: 7. Not available. Nomen nudum.

Nematus albilabris  Boheman, 1852: 172. Syntype(s) not found in NHRS. Type locality: Wärnaby and Anneberg, Småland, Sweden.

Nematus albilabris  Thomson, 1863: 622. Primary homonym of Nematus albilabris  Boheman, 1852 [= Pristiphora albilabris  (Boheman, 1852)]. Holotype ♀ ( NHRS-HEVA000003749) in NHRS, examined. Type locality: Bohuslän, Sweden.

Nematus collaris  Stein, 1884: 305-308. 4 ♀ syntypes possibly in BMNH, not examined. Type locality: Chodov, Czech Republic. Synonymised with Lygaeonematus albilabris  by Konow (1892).

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).

Host plants.

Betula  sp. ( Conde 1934, Benson 1958), B. pubescens  Ehrh (ex ovo rearing experiments by VV).

Rearing notes.

Ovipositing experiment no. 16/1972: Finland, North Karelia, Kontiolahti, Venejoki. One captured female laid eggs on 2-3.VI.1972 in pockets on underside of teeth (leaf edges) of young leaves of Betula pubescens  . Larvae hatched on 8-9.VI.1972, four larval instars were observed. The final feeding instar lasted about 17 days. Rather small prepupae (male sex?) were seen on 4.VII.1972. No extra moult after feeding.

Distribution and material examined.

Palaearctic. Specimens studied are from Finland and Sweden.
