We are grateful to associate editor Nathalie Yonow and reviewers Adrienne Jochum and Pierre Lozouet for constructive comments that helped improve the manuscript. We are grateful to all the people who helped us with field work in various ways, by hosting us at their institutions, helping with logistics, or accompanying us in the field. Our study would have been impossible without their generous help and efforts: Teddy Chua in Brunei Darussalam; Neil Bruce in Queensland; Adam Bourke and Richard Willan in the Northern Territory; Vivian Ang, Don Dumale, and Marivene Manuel in the Philippines. Accessing mangrove sites would have been impossible without help from local fishermen and villagers. We also thank the collection managers of various institutions for accepting to host our material in their collections and sending us specimens on loan: Brunei Museum, Natural History, Brunei Darussalam; Institute of Tropical Biology, Zoology Collection, Vietnam Academy of Science and Technology, Ho Chi Minh City, Vietnam; Museum of Tropical Queensland, Townsville, Queensland, Australia; Museum and Art Gallery of the Northern Territory, Australia; National Museum of the Philippines, Manila, Philippines; Universitas Malikussaleh, North Aceh, Sumatra, Indonesia; Mollusk Collection, Universiti Sains Malaysia, Penang, Malaysia; Zoological Reference Collection, Lee Kong Chian Natural History Museum, National University of Singapore. Specimens were collected following local regulations, as overseen by Shau Hwai Tan (Malaysia), Marivene Manuel (Philippines), Munawar Khalil (Indonesia), and Quảng Ngô Xuân (Vietnam). Collecting in Brunei, New South Wales, Queensland, and the Northern Territory was done with permits from local institutions. A research permit was issued to Benoît Dayrat in Singapore (#NP/RP10-020). We thank the Ministry of Research, Technology and Higher Education, Republic of Indonesia (Ristek-Dikti) that issued a research permit to Benoît Dayrat (Ristek #134/SIP/FRP/ E5/Dit.KI/VI/2017). We also wish to thank the Universitas Malikussaleh for being our home base institution in Indonesia. 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 - As part of an ongoing effort to revise the taxonomy of air-breathing, marine, onchidiid slugs, a new genus, Laspionchis Dayrat & Goulding, gen. nov., is described from the mangroves of South-East Asia. It includes two new species, Laspionchis boucheti Dayrat & Goulding, sp. nov., and Laspionchis bourkei Dayrat & Goulding, sp. nov., both distributed from the Malacca Strait to the Philippines and Australia. This study is based on extensive field work in South-East Asia, comparative anatomy, and both mitochondrial (COI and 16S) and nuclear (ITS2 and 28S) DNA sequences. The two new species are found in the same habitat (mud surface in mangrove forests) and are externally cryptic but are distinct anatomically. Both species are also strongly supported by DNA sequences. Three cryptic, least-inclusive, reciprocally-monophyletic units within Laspionchis bourkei are regarded as subspecies: L. bourkei bourkei Dayrat & Goulding, ssp. nov., L. bourkei lateriensis Dayrat & Goulding, ssp. nov., and L. bourkei matangensis Dayrat & Goulding, ssp. nov. The present contribution shows again that species delineation is greatly enhanced by considering comparative anatomy and nuclear DNA sequences in addition to mitochondrial DNA sequences, and that thorough taxonomic revisions are the best and most efficient path to accurate biodiversity knowledge.
