The systematics of freshwater gastropods attributed to Brotia H.Adams, 1866 based on conchological similarities has long remained confusing. Previously, only scattered information was available on the taxonomy and virtually nothing on the phylogenetic relationships of these viviparous snails that are widely distributed in Southeast Asia. To resolve the systematic confusion, the relevant types were re-examined together with additional material from various museum collections, supplemented by… 
Annotated catalogue of the nominal taxa of Southeast Asian freshwater gastropods, family Pachychilidae Troschel, 1857 (Mollusca, Caenogastropoda, Cerithioidea), with an evaluation of the types
TLDR
The present paper briefly summarises the taxonomic history of the Pachychilidae, catalogues the described pachy chilid genera, species and subspecies known from Southeast Asia, and documents their relevant type material located in various museum collections world-wide.
Convergence Caused Confusion: On the Systematics Of the Freshwater Gastropod Sulcospira pisum (Brot, 1868) (Cerithioidea, Pachychilidae)
TLDR
Evidence is presented that “Melania” pisum is not a thiarid species closely related to Balanocochlis glans (Busch, 1842), as has been supposed with respect to the very similar shells of both species.
Systematics, molecular genetics and historical zoogeography of the viviparous freshwater gastropod Pseudopotamis (Cerithioidea, Pachychilidae): a relic on the Torres Strait Islands, Australia
TLDR
The historical background of the discovery, the taxonomic history, and an evaluation of the systematic position of Pseudopotamis are provided, including molecular genetic data (genes of cytochrome c oxidase subunit I and 16S ribosomal DNA).
Molecular phylogeography and reproductive biology of the freshwater snail Tarebia granifera in Thailand and Timor (Cerithioidea, Thiaridae): morphological disparity versus genetic diversity
TLDR
A country-wide chorological approach focussing on the conchologically distinct and genetically diverse lineages of Tarebia allows to discuss questions of this either reflecting subspecific forms versus being distinct species within a narrowly delimited species complex.
A glimpse in the dark? A first phylogenetic approach in a widespread freshwater snail from tropical Asia and northern Australia (Cerithioidea, Thiaridae)
TLDR
It is suggested that populations from the Oriental region cannot be distinguished on the basis of shell morphology, radula characters and their reproductive mode and are monophyletic based on mitochondrial sequences, highlighting the need for a comprehensive revision of the genus-group systematics of Thiaridae as a whole.
Anatomy of an adaptive radiation: a unique reproductive strategy in the endemic freshwater gastropod Tylomelania (Cerithioidea: Pachychilidae) on Sulawesi, Indonesia and its biogeographical implications
TLDR
An evaluation of anatomical findings in the live-bearing pachychilid freshwater gastropod Tylomelania suggests the existence of a single monophyletic lineage endemic to this island, leading to the hypothesis that the common ancestor of both genera originated somewhere on the northern Australian continental margin.
Morphology, reproductive biology and molecular genetics of ovoviviparous freshwater gastropods (Cerithioidea, Pachychilidae) from the Philippines, with description of a new genus Jagora
TLDR
The new genus Jagora of the family Pachychilidae Troschel, 1857 is described for the type species Melania asperata Lamarck from the Philippines, characterized by additional unique properties of the reproductive system including a deeply incised and long sperm gutter in the medial lamina, a very short and posteriorly positioned spermatophore bursa formed by the medialLamina, and a prominent lateral ridge functioning as a seminal receptacle.
MULTIPLE ORIGIN OF VIVIPARITY IN SOUTHEAST ASIAN GASTROPODS (CERITHIOIDEA: PACHYCHILIDAE) AND ITS EVOLUTIONARY IMPLICATIONS
TLDR
It is hypothesized that the production of large eggs, which is necessitated by the exploration of freshwater, represents a preadaptation existing in those ancestors from which viviparous pachychilid lineages eventually evolved in Southeast Asia.
Novel reproductive modes in freshwater clams: brooding and larval morphology in Southeast Asian taxa of Corbicula (Mollusca, Bivalvia, Corbiculidae)
TLDR
Two newly observed modes of brooding in species endemic to Sulawesi are reported, tetragenous brooding (i.e. in both demibranchs) and prolonged incubation in the maternal gills, with juvenile shells reaching up to 1.3 mm in length and with a well-developed hinge in Corbicula possoensis.
Radiating in a river: systematics, molecular genetics and morphological differentiation of viviparous freshwater gastropods endemic to the Kaek River, central Thailand (Cerithioidea, Pachychilidae)
TLDR
Recent diversification combined with ecological separation and trophic specialization parallels conditions found, albeit on a more specious level, in the lacustrine species flock of the closely related pachychilid genus Tylomelania, which is endemic to ancient lakes on the Indonesian island of Sulawesi.

TLDR
The genus Cerithium Bruguiere comprises a large group of morphologically highly variable species characterized by many-whorled, elongate shells having ovate apertures, slightly reflected anterior canals and sculpture, consisting of axial ribs, spiral cords with beads and nodes, and randomly placed varices.
The life history of Brotia hainanensis (Brot, 1872) (Gastropoda: Prosobranchia: Thiaridae) in a tropical forest stream
TLDR
This species shows two peaks of recruitment per annum, one in spring and a second in the latter part of summer, and it is suggested that the modification of the life cycle of B. hainanensis from the type more usually encountered in freshwater prosobranchs reflects that this is an r-selected species adapted to a habitat where high density-independent mortality occurs.

TLDR
In examining the distribution patterns of dominant freshwater families with regard to their biological, ecological, and overall phylogenetic relationships it is evident that ecology plays a major role along with dispersal and vicariance.

The fox sparrows of North America illustrate the effect of the arrangement of habitats, in a way beautifully worked out by Swarth (1920), where representatives of a species inhabiting the entire linear strip have a different appearance, depending upon which part or small section of the strip they live in.
