Pristiphora depressa (Hartig, 1840) Figs 24, 82-83, 184

Nematus depressus Hartig, 1840: 24. Lectotype ♀ (designated by Liston and Späth 2008) in ZSM, examined. Type locality: not stated.

Pristiphora Carpentieri [sic!] Konow, 1902: 18. Lectotype ♀ (GBIF-GISHym3902; designated by Oehlke and Wudowenz 1984), examined. Type locality: Amiens, Nord-Pas-de-Calais-Picardie, France.

Similar species.

The most similar species are P. subbifida and P. tetrica . Pristiphora subbifida has an extensively pale head in dorsal view (with only small pale spots in P. depressa ) and at least partly pale metapostnotum (Fig. 38) (black in P. depressa ). Pristiphora tetrica , on the other hand, has a darker head than P. depressa (with black supraclypeal area and usually without pale spots dorsally in P. tetrica ). For more details see Liston and Späth (2008) and Liston et al. (2013). Male unknown.

Genetic data.

Based on COI barcode sequences, P. depressa forms its own BIN cluster (BOLD:ABU7027) (Fig. 3). Maximum distance within the BIN is 0.61%. The nearest neighbour to BOLD:ABU7027, diverging by minimum of 7.06%, is BOLD:AAU8503 ( P. subbifida ).

Host plants.

Acer sp. ( Carpentier 1901). Adults reared from the larvae mentioned by Carpentier (1901) were described a year later as P. carpentieri by Konow (1902).

Distribution and material examined.

West Palaearctic. Specimens studied are from France, Germany, Italy, and Sweden.
