Arrup edentulus ( Attems, 1904)

This species was described from ‘Przewalsk’ (Tian Shan, Kyrgyzstan) and then recorded from Taiwan by Wang (1956). At the moment, the relationships between this species and other Asiatic Arrup are unclear, as the original description and drawings published by Attems (1904) are quite poor. Based on the redescription and drawings published by Titova (1975), this species seems recognisable mainly by the presence of a very strong tooth on the first forcipular article.

Crabill (1964) and Titova (1975) claimed that the records from Taiwan are dubious, and we agree with their opinion: the large distribution gap between the type locality of A. edentulus and Taiwan suggests that these areas could hardly host the same species.
