Aporrectodea caliginosa (Lumbricidae) georeferenced occurrences from Russian-language scientific literature

Aporrectodea caliginosa (Savigny, 1826) is a very common endogeic earthworms species, but little is known about it’s distribution range in Russian territory. This is because a significant amount of data is available only in Russian-language, including "grey literature" and remains inaccessible to researchers around the world. Here we represent the dataset containing occurrences extracted from Russian-language scientific literature.
