|Title||Studies on Idiocerine Leafhoppers XII. Idioscopus Clavosignatus spec. nov. (Homoptera, Cicadellidae)|
|Abstract||Among material from the Leiden Museum loaned to me for study a new species of Idioscopus was found that is described here. A summary of the species in the genus is added in two tables.|
In the descriptions below 30 micrometer units are equivalent to 1.0 mm.
The types are deposited in the Leiden Museum, The Netherlands, in my own collection, and in the United States National Museum, Washington.
