In the list I enumerate the results of recent collections, adding and also comparing with the results by Domokos and Lennert, 2009 in connection the area of judetul Sălaj /Szilágyság. From faunistical and conservation point the most important results are species of Acicula perpusilla, Agardhiella lamellosa, Drobacia banatica, Unio crassus, Vertigo angustior, Vertigo moulinsiana and Vertigo substriata. thing worth mentioning. The most important outcome of this study was the discovery of a new Bythinella species: Bythinella gregoi GLÖER & ERŐSS and Alzoniella (?) species which is a new species and genus for Romania. The other important finding a very big empty shell of Mastus bielzi which could be a new subspecies. These recent researches made a result rare or new endemic species, it pays attention that the well-known, but not so deeply researched areas can be faunistical or scientific surprised.
