Pristiphora coactula (Ruthe, 1859) Nematus coactulus Ruthe, 1859: 307-308. ♀. Holotype. Type locality: Iceland. Lygaeonematus (Lygaeotus) trochantericus Lindqvist, 1952: 101-102. ♀. Holotype (http://id.luomus.fi/GL.7708) and paratypes (♀, ♂). Type locality: Finland, Utsjoki, Outakoski. syn. nov. Notes. The nuclear sequence data obtained for this study revealed three main clusters within the Pristiphora carinata group: P. carinata , P. coactula , and P. borea + P. groenblomi + P. albilabris (Fig. 30). No nuclear sequence data are yet available for P. breadalbanensis (Cameron, 1882b) and P. lativentris (Thomson, 1871). A nearly perfect match morphologically to the L. trochantericus holotype is ZMUO.035514, which falls within the P. coactula cluster based on nuclear DNA (Fig. 30). There are two main clusters based on COI sequences, one of which contains only P. borea (Konow, 1904) and P. groenblomi (Lindqvist, 1952) and the other one all species (Fig. 31). Within the COI cluster containing all species (Fig. 31), P. borea , P. groenblomi , and P. albilabris (Boheman, 1852) ( Betula feeders) tend to separate from P. coactula ( Salix ) and P. carinata (Hartig, 1837) ( Vaccinium ). Based on the specimens having nuclear data, the species (mainly females) of the Pristiphora carinata group may be separated by the following key, although it might not always work for all specimens, particularly P. coactula and P. borea . Excluded from the key are the (sub)arctic species P. breadalbanensis and P. lativentris. Pristiphora Pristiphora lativentris may have somewhat different serrulae from the other species (almost papilliform, see fig. 215 in Prous et al. 2017). The identity of Pristiphora breadalbanensis (most similar to P. borea and P. coactula ) needs further research to confirm if characters (e.g. structure of median mesoscutal lobes) mentioned by Benson (1958) to separate this species are reliable. [table omitted] Examples of lancets of P. borea , P. carinata , and P. coactula are shown in Fig. 32A-C, but more specimens ...
