Redescription of Macrobiotus tridigitus Schuster, 1983 and the erection of a new genus of Tardigrada (Eutardigrada, Macrobiotidae)

摘要

Based on claw morphology Macrobiotus tridigitus is transferred to the new genus Schusterius. Claws of the genus Schusterius differ from those in the genera Calcarobiotus and Macrobiotus in the unusually well-developed accessory points which are transformed into very long and thin additional claws, arranged above double claws on each leg. A redescription of Schusterius tridigitus comb. nov. based on the holotype and the paratype is also given.
