Material examined. Denmark: NEJ: Skagen , V.1990, 1 ♂ and 2 ♀♀ (P. Falck), and 3.V.1991, 1 ♀ (O. Karsholt). *Russian Fennoscandia: Ik: Terijoki [= Zelenogorsk], 25.VI.1933, 1 ♀ (V.J. Karvonen); Ka: Koiviston mlk., Vasikkasaari, 25.VI.1938, 1 ♂ (E. Kangas); Seiskari [= Ostrov Seskar], [1938], 1 ♀ (A. Merisuo) .

Distribution. Denmark, Estonia, Finland, Latvia, Lithuania, Norway, Sweden, *Russian Fennoscandia.—Westpalearctic: Europe, Turkey ( Kimsey & Bohart 1991).

Remarks. The species is closely related to P. auratus and has a similarly wide distribution, but it is much more local and less abundant. The species was reported from Norway only recently on the basis of two old museum specimens ( Artsdatabanken 2010). However, many unpublished new records exist from different parts of the country (provinces AK, Ø, BØ, TEY, TEI). The species was reported from Denmark by Soon (2004) on the basis of four specimens found in ZMUC (see data above). In Finland, the species has been included in the national red list as near threatened ( Paukkunen 2010), and in Norway as data deficient ( Hansen et al. 2010). Kunz (1994) synonymized P. triangulifer with P. auratus , but most authors have considered them as separate species.
