The German author loathed the name Phalangium, so he proposed the replacement Opilio (only much later they were regarded as different genera). He even considered Phalangium opilio Linnaeus 1758 to be a synonym of Phalangium parietinum De Geer 1778, only with inverted precedence. He criticized the previous authors for giving only squalid information (which was by the way the reason he did not recognize the difference between both species), mentioned the huge variation in color patterns (some of which was caused by his dealing with two species here) and provided a redescription of the animal we today know as O. parietinus.

"Ob obige Schriftsteller insgesammt diese bestimmte Art beschrieben haben, ist wohl unmöglich auszumachen, weil ihre Beschreibungen zu wenig genau find; ich führe sie also auch mehr nur as solche an, die der ganzen Gattung erwähnen. Es hält überhaupt sehr schwer, sichere specifische Kennzeichenen anzugeben, da fast kein einziges Individuum mit dem andern genau übereinstimmt, und auch nach den verschiedenen Stufen des Alters und der Häutungen die Farben und Zeichnungen ganz verschieden seyn können." (Herbst, 1798: 12-13).
