Considerations on the claws of the Apochela and a novel detail of the bucco-pharyngeal apparatus of the genus Milnesium (Tardigrada: Apochela: Milnesiidae)

A New Species of Bisexual Milnesium (Eutardigrada: Apochela) Having Aberrant Claws from Innhovde, Dronning Maud Land, East Antarctica

“…Illustrations were made using a drawing tube attached to a BX-50 microscope and finished with Inkscape software (https://inkscape.org/). The terminology for the Milnesium claw system generally followed Camarda et al (2022), i.e., we now replace the terms “primary/secondary branches” in the previous works (reviewed in Suzuki, 2022) by “primary/secondary claws”, and instead we call the hooks, or points, on the secondary claws “branches”. Following Suzuki (2022), we avoid using the directional terms internal/external for leg I–III, and describe the CC by the revised notation system (Suzuki, 2022) with a modification, i.e., the number of “branches” on the “secondary claws” expressed in brackets as { anterior / posterior } in order through all legs.…”
