N1 - Funding Information:
We are extremely grateful to all the people that helped us with field work in various ways, either by hosting us, assisting with some logistics, or accompanying us in the field. Our study would have been impossible without their generous help and efforts: Sudhir Sapre and CR Sreeraj in India; Peter Ng (Lee Kong Chian Natural History Museum, National University of Singapore) in Singapore; Teddy Chua in Brunei Darussalam; Marivene Manuel, Vivian Ang, and Don Dumale (all from the National Museum of the Philippines, Manila) in the Philippines. Accessing mangrove sites would have been also impossible without the help from anonymous local fishermen and villagers (who also kept us safe on more than one occasion, advising us for instance not to go in the water when they knew crocodiles had been recently spotted). We are grateful to Dr. Rahul C. Salunkhe and Dr. Yogesh Shouche (National Center for Cell Science, Pune, and Bombay Natural History Society, Mumbai) for their help with the DNA sequencing of the specimens from India. We also thank the collection managers of various institutions for sending us specimens on loan: Brunei Museum, Natural History, Brunei Darussalam; Institute of Tropical Biology, Vietnam Academy of Science and Technology, Ho Chi Minh City, Vietnam; Muséum national d'histoire naturelle, Paris, France; Natural History Museum, London, United Kingdom; National Museum of the Philippines, Manila, Philippines; Naturmuseum Senckenberg, Frankfurt-am-Main, Germany; Swedish Museum of Natural History, Stockholm, Sweden; Universiti Sains Malaysia, Penang, Malaysia; Zoologisches Museum, Berlin, Germany; Zoologisches Museum, Hamburg, Germany; Zoological Reference Collection, Lee Kong Chian Natural History Museum, National University of Singapore. The SEM pictures were taken at the Zeiss SIGMA FE-SEM (Field Emission Scanning Electron Microscopy) at the Huck Institutes of the Life Sciences, the Pennsylvania State University. Stefan Achleitner helped with the translation of some German articles. We thank Nathalie Yonow (subject editor), António M. de Frias Martins and Adrienne Jochum (reviewers) for providing constructive comments that greatly improved the manuscript, as well as the whole editorial team from Zookeys. Finally, this work was supported by the Eberly College of Science at the Pennsylvania State University and by a REVSYS (Revisionary Syntheses in Systematics) award from the US National Science Foundation (DEB 1419394).

N2 - In an effort to clarify the species diversity of onchidiid slugs, the taxonomy of the genus Onchidium Buchannan, 1800 is revised using an integrative approach. New, fresh specimens were collected in a large number of places, including type localities. The genus Onchidium is redefined here as a clade including only three species which are strongly supported by both morphological and molecular data. All three species were already named: the type species O. typhae Buchannan, 1800, O. stuxbergi (Westerlund, 1883), and O. reevesii (J.E. Gray, 1850). With the exception of a re-description of O. typhae published in 1869, all three species are re-described here for the first time. First-hand observations on the color variation of live animals in their natural habitat are provided. The anatomy of each species is described. Important nomenclatural issues are addressed. In particular, Labella Starobogatov, 1976 is regarded as a junior synonym of Onchidium and Labella ajuthiae (Labbé, 1935) and O. nigrum (Plate, 1893) are regarded as junior synonyms of O. stuxbergi. The nomenclatural status of several other species names is discussed as well. Many new records are provided across South-East Asia and precise ranges of geographic distributions are provided for the genus Onchidium and its three species. Distinctive features that help distinguish the genus Onchidium from other onchidiids are provided, as well as an identification key for the three species.
