The Coral Triangle and Strait of Malacca are two distinct hotspots of mangrove biodiversity.

Knowledge of the biogeography of marine taxa has lagged significantly behind terrestrial ecosystems. A hotspot of marine biodiversity associated with coral reefs is known in the Coral Triangle of the Indo-West Pacific, but until now there was little data with which to evaluate broad patterns of species richness in the coastal fauna of ecosystems other than coral reefs. This data is critically needed for fauna with low functional redundancy like that of mangroves, that are vulnerable to habitat loss and rising sea levels.

Global diversification and evolutionary history of onchidiid slugs (Gastropoda, Pulmonata).

Many marine species are specialized to specific parts of a habitat. In a mangrove forest, for instance, species may be restricted to the mud surface, the roots and trunks of mangrove trees, or rotting logs, which can be regarded as distinct microhabitats. Shifts to new microhabitats may be an important driver of sympatric speciation.

Systematic revision of the genus Fleming, 1822 (Gastropoda, Euthyneura, Pulmonata, Onchidiidae).

The genus Fleming, 1822 includes all the onchidiid slugs with dorsal gills. Its taxonomy is revised for the first time based on a large collection of fresh material from the entire Indo-West Pacific, from South Africa to Hawaii. Nine species are supported by mitochondrial (COI and 16S) and nuclear (ITS2 and 28S) sequences as well as comparative anatomy.

A new species and new records of slugs (Gastropoda, Euthyneura, Pulmonata, Onchidiidae) in South-East Asia.

A new species, Dayrat & Goulding, , is described, bringing the total to four known species in the genus Buchannan, 1800. is a rare species with only nine individuals found at three mangrove sites in the Andaman Islands and the Strait of Malacca (western Peninsular Malaysia and eastern Sumatra). The new species is delineated based on mitochondrial (COI and 16S) and nuclear (ITS2 and 28S) DNA sequences as well as comparative anatomy.

A new genus of air-breathing marine slugs from South-East Asia (Gastropoda, Pulmonata, Onchidiidae).

As part of an ongoing effort to revise the taxonomy of air-breathing, marine, onchidiid slugs, a new genus, Dayrat & Goulding, , is described from the mangroves of South-East Asia. It includes two new species, Dayrat & Goulding, , and Dayrat & Goulding, , 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.

Integrative taxonomy of a new and highly-diverse genus of onchidiid slugs from the Coral Triangle (Gastropoda, Pulmonata, Onchidiidae).

A new genus of onchidiid slugs, Goulding & Dayrat, , is described, including ten species. Five species were previously described but known only from the type material: (Lesson, 1830), (Semper, 1880), (Plate, 1893), (Stantschinsky, 1907), and (Stantschinsky, 1907), all of which were originally classified in Buchannan, 1800. Many new records are provided for these five species, which greatly expand their known geographic distributions.

Integrative taxonomy of the genus Buchannan, 1800 (Mollusca, Gastropoda, Pulmonata, Onchidiidae).

In an effort to clarify the species diversity of onchidiid slugs, the taxonomy of the genus Buchannan, 1800 is revised using an integrative approach. New, fresh specimens were collected in a large number of places, including type localities. The genus is redefined here as a clade including only three species which are strongly supported by both morphological and molecular data.

Diversity of Indo-West Pacific Siphonaria (Mollusca: Gastropoda: Euthyneura).

Species of the limpet genus Siphonaria (Gastropoda: Euthyneura) are commonly found in the rocky intertidal, worldwide, except in the Arctic. In total, 205 species-group names are available and not permanently invalid. However, estimating the actual species diversity of Siphonaria has remained challenging, mainly because past authors have interpreted differently the variation of shell characters, resulting in different taxonomic accounts.
