Pristiphora melanocarpa (Hartig, 1840)

Nematus melanocarpus Hartig, 1840: 27. Lectotype ♀ (GBIF-GISHym3349; here designated) in ZSM, examined. Type locality: North Germany (according to introduction).

Nematus funerulus Costa, 1859: 20-21. Syntypes ♂♀ possibly in MZUN, not examined. Type locality: vicinity of Naples, Campania, Italy.

Nematus wuestneii Stein, 1885 [mandatory correction of incorrect original spelling N. Wüstneii]: 304. Lectotype ♀ (here designated) in BMNH, examined. Type locality: Chodov [Chodau], Czech Republic.

Pristiphora ortinga Kincaid, 1900: 349-350. Holotype ♀ (USNMENT00778199) in USNM, not examined. Type locality: Kukak Bay, Alaska, USA. Note. Synonymised by Smith (1979: 63).

Similar species.

The most similar species is P. ruficornis , which has paler antennae compared to P. melanocarpa . Females have the ventral side of antennae uniformly black (Fig. 24 View Figures 18–36 ) or only slightly paler, while P. ruficornis has a distinctly paler ventral side (Fig. 25). Males of P. melanocarpa also tend to have darker antennae than in P. ruficornis , but penis valves should be studied in specimens that have conspicuously pale antennae. The ventro-apical spine of the penis valve bends distinctly more sharply (being almost L-shaped) and is usually narrower (Figs 80 View Figures 77–86 , 82 View Figures 77–86 ) than in P. ruficornis (Figs 79 View Figures 77–86 , 81 View Figures 77–86 ).

Genetic data.

Based on COI barcode sequences, specimens are divided between three BIN clusters (BOLD:AAG3540, BOLD:ACZ4465, BOLD:ACZ4466), two of them (BOLD:ACZ4465 and BOLD:ACZ4466) including also P. ruficornis (Fig. 1 View Figure 1 ). These BIN clusters form a monophyletic group (Fig. 1 View Figure 1 ) and minimum distances between them are only 1.13-1.50%. Neither do nuclear TPI sequences support separation of P. melanocarpa and P. ruficornis (Fig. 2 View Figure 2 ).

Host plants.

Betula pendula Roth ( Kangas 1985), B. pubescens Ehrh. ssp. czerepanovii (N. I. Orlova) Hämet-Ahti (rearings by VV), B. nana L. (rearings and ex ovo rearing experiments by VV). The records from Salix (e.g. Lorenz and Kraus 1957) are probably based on misidentifications. A male paratype of P. coniceps Lindqvist (http://id.luomus.fi/GL.5208) that belongs to P. melanocarpa , was reared from larvae found on Salix ( Lindqvist 1955), but this should not be taken as a clear evidence for host association as no ex ovo rearings were involved.

Distribution and material examined.

Holarctic. Specimens studied are from Canada, Estonia, Finland, France, Germany, Norway, and Sweden.
