Pristiphora tenuiserra (Lindqvist, 1959) Figs 119, 123, 173, 302

Micronematus tenuiserra Lindqvist, 1959: 72. Holotype ♀ in MZLU (DEI-GISHym31572), examined. Type locality: Knivsta, Uppland, Sweden.

Similar species.

Females can be distinguished from other species by the combination of the structure of valvula 3 (long and narrow and practically without scopa; Figs 119, 123) and (at least usually) relatively dark coloration (head dorsally black or with small pale spots, thorax black, abdomen at least dorsally black). Males are best recognised by examining penis valves (see the Key).

Genetic data.

Based on COI barcode sequences (only one specimen in BOLD), P. tenuiserra forms its own BIN cluster (BOLD:ADD2616) (Fig. 5). The nearest neighbour to BOLD:ADD2616, diverging by a minimum of 5.22%, is BOLD:ACO1401 ( P. euxantha ). No nuclear data are available.

Host plants.

Unknown, but the structure of valvula 3 suggests that the species is probably a conifer-feeder.

Distribution and material examined.

West Palaearctic. Specimens studied are from Finland, Germany, Poland, and Sweden.
