The original material of three species from the checklist of spiders of the Netherlands have been examined, because there was some doubt about their status. Ozyptila blackwalli (juvenile females) most likely belongs to O. nigrita Thorell. Xysticus lineatus (1 female) belongs to X. sabulosus (Hahn). Dipoena inornata (one subadult male) probably belongs to D. prona (Menge) because it lacks the characteristic silky haircover on the abdomen.
