Tala-tchu et By-tchu" collected by Przewalsky in 1884. In the collection of ZIN, we examined two males which matched with the original literature. We designated the male with its genitalia dissected as the lectotype herein, for the taxonomic purpose of fixing the species name to a single specimen and preventing further confusion.
