Abstract: The bicolored shrew Crocidura leucodon so far has not been reported in Hamburg with certainty. Some plausible historical records before 1920 are present; in turn, two more recent records are doubtful for different reasons. Hence, the Red List status of the species for Hamburg has to be considered uncertain (either not present, or extinct). A citizen scientist provided a specimen of an unknown shrew, an accidental catch by a snap trap, to the Centrum für Naturkunde. The specimen was caught on the 12th of September 2019 in Tatenberg, Hamburg. It was morphologically and genetically clearly determined as C. leucodon. This find represents the first confirmed record of C. leucodon for the federal state of Hamburg and increases the number of shrew species recorded in Hamburg to five. The Red List status of the species will have to be reevaluated.

Lost and found – Fritz Müller´s type material of Glossiphonia verrucata (Fr. Müller, 1844) (Hirudinida, Glossiphoniidae) with notes on the leech fauna of lake Tegel in Berlin (Germany) https://evolsyst.pensoft.net/article/30793/ Evolutionary Systematics 2(2): 163-168

Abstract: In 1844, the famous German biologist Fritz Müller published his dissertation about the leech fauna of lakes in Berlin. This study not only addressed the occurrence of leeches in the different lakes, but also contains the description of a new species - Glossiphonia verrrucata (Fr. Müller, 1844). Unfortunately, he never mentioned how many specimens he found and where he deposited the material of his dissertation research. Thus, it came as a surprise that the material appeared in the small leech collection of the Zoological Museum of the University of Greifswald. Here, we provide an overview of the material focusing especially on the four syntypes of G. verrucata. Since this is a rarely found species, we further explored historical material from the type locality, Lake Tegel, held in other museums. Our survey revealed that the material collected by Müller is the only one known to date from the species-rich Lake Tegel, which is inhabited by 14 species of freshwater leeches.
