Pristiphora opaca  Lindqvist, 1955b: 42-43. Holotype ♀ (http://id.luomus.fi/GL.5204) in MZH, examined. Type locality: Pihtipudas, Central Finland.

Similar species.

Based on the external morphology, the most similar species are P. albitibia  , P. confusa  , P. pusilla  , P. sootryeni  , and P. subopaca  . The species is best distinguished through the structure of male penis valve (Fig. 270). Unfortunately, it is rather difficult to distinguish females from P. subopaca  as the differences in the lancets are small (Figs 197-198). The best character might be the structure of the tangium: on its basal part, P. opaca  appears to have a fold (Fig. 197) that is absent in other species of the ruficornis  group. There are also slight differences in external morphology between P. opaca  and P. subopaca  . In P. opaca  (Fig. 40), the pterostigma is apically brown and basally dark brown (uniformly yellow in P. subopaca  ; Fig. 39), antennae are slightly paler ventrally (uniformly black in P. subopaca  ), and claws seem to have a somewhat smaller subapical tooth (Fig. 22) than in P. subopaca  (Fig. 23).

Genetic data.

Based on COI barcode sequences, P. opaca  belongs to the same BIN cluster (BOLD:AAG3568) as P. aphantoneura  , P. bifida  , P. confusa  , P. pusilla  , P. staudingeri  , and P. subopaca  (Fig. 4). Maximum distance within the BIN is 3.33% and minimum between species distance is 0.00%. The nearest neighbour to BOLD:AAG3568, diverging by a minimum of 2.76%, is BOLD:AAQ2302 ( P. armata  and P. leucopus  ). Based on nuclear data (one specimen and both genes combined), the nearest neighbour is 0.4% different ( P. luteipes  or P. pusilla  ).

Host plants.

Unknown.
