Comments. Haplodrassus concertor  was described by Simon (1878) from one locality, Vernet-les-Bains in the Pyrénées-Orientales. Material from this locality could not be traced, so a large series of specimens labelled Auvergne, Pyrénées, Aigoual AR9209 is indicated here as type series. The available illustrations of the epigyne of H. concertor  appear to be Simon’s simple sketches (1878, fig. 24; 1914, fig. 251) in “Les Arachnides de France ” and the drawings by Denis (1958, figs 1‒2). The females collected by us in the Pyrénées agree with these figures. For the male, Simon (1914) presents a figure of the male palp in his identification table, line 8, and this line finally leads to two species: H. concertor  and H. signifer  . It is nowhere precised if it is the palp of either of the two. According to the World Spider Catalogue (2017), fig. 249 represents the palp of H. concertor  . According to Simon (1914), males of H. concertor  and H. signifer  are very similar (“Les mâles des deux espèces sont souvent très dificiles à distinguer, tandis que les caractères des femelles sont beaucoup plus nets”). In our material, the male of H. concertor  is clearly different from H. signifer  . The conclusion must be that Simon mistook a male of H. signifer  for a male of H. concertor  , which is clearly different as proved by our newly collected material. In the World Spider Catalogue, the attribution of figure 249 to H. concertor  , must be deleted and changed to H. signifer  .

Description. Measurements: Male (n=4): Total length 5.4‒5.8 mm; carapace 2.08‒2.82 long, 1.71‒2.01 wide. Female (n=2): Total length 6.6‒7.7 mm; carapace 2.62‒2.86 long, 2.01‒2.24 wide.

Colour: Carapace reddish brown with grey striae, margin and eye region blackish; chelicerae and sternum dark reddish brown; legs yellowish brown; abdomen grey to dark grey, dorsally sometimes with slight indications of pale grey stripes and chevrons.

Male palp ( Figs 207‒210View FIGURES 205–213): Tibial apophysis shorter than the tibia’s diameter, terminally rounded; embolic apophysis slightly bent, relatively short, much shorter than embolus.

Epigyne ( Figs 211‒213View FIGURES 205–213): Hood wide, with straight posterior margin, slightly wider than fovea but much narrower than areola; fovea elongated, 1.5 x as long as wide, with parallel margins.

Distribution. Certified material has been seen from the French departments Ariège, Hautes-Pyrénées, Pyrénées- Atlantiques and Pyrénées-Orientales. It was furthermore cited in Gran Paradiso in Italy ( Caporiacco 1928b), but this record needs confirmation.
