the long-lasting story of the wrong naming of silometopus ambiguus as s. curtus (araneae: linyphiidae)

Silometopus ambiguus (O. Pickard-Cambridge, 1905) is a species occurring in coastal habitats from north-eastern to western Europe. S. curtus (Simon, 1881), occurring in southern France and north-eastern Spain, was for a long time mixed up with S. ambiguus, even though corrections have been published very early and several times. This contribution summarizes publications on this topic, discusses doubtful records of both species and proposes corrections for the World Spider Catalog; and thus tries to avoid repetitions of the mistake in the future.
