Ceratophysella macrocantha Stach, 1946 (Collembola, Hypogastruridae): a redescription of a forgotten species from the Alps

摘要

Ceratophysella macrocantha Stach, 1946 is redescribed on the basis of a syntype specimen from the Austrian Alps which is here designated as the lectotype. This species has the chaetotaxy of the type B and an empodium with a long filament. It is closely related to nine species/forms, two of which, C. attenuata Gisin, 1960 nec Cassagnau, 1959 from the Swiss Alps and C. recta Cassagnau, 1959 from the Pyrenees, are most similar.
