Abstract This study aims at a better understanding of the evolutionary significance of viviparity in some freshwater gastropods. We use a phylogeny based on partial sequences of the mitochondrial 16S gene of representatives of the limnetic and pantropical Pachychilidae to infer the relationships within this particular group of cerithioideans and the evolution of reproductive strategies. The phylogeny presented herein implies a new systematization and suggests that viviparity has appeared three… 
Phylogeny of freshwater viviparid snails in Japan
TLDR
Extensive incongruence between molecular phylogeny and the current taxonomy of the freshwater gastropod family Viviparidae in Japan is documented, due to incomplete lineage sorting, introgressive hybridization and/or phenotypic plasticity.
The Species Flocks of the Viviparous Freshwater Gastropod Tylomelania (Mollusca: Cerithioidea: Pachychilidae) in the Ancient Lakes of Sulawesi, Indonesia: The Role of Geography, Trophic Morphology and Color as Driving Forces in Adaptive Radiation
The study of species flocks in island settings such as ancient lakes can contribute significantly to our understanding of fundamental evolutionary processes, such as speciation, radiation,
Phylogeny of the gastropod superfamily Cerithioidea using morphology and molecules
TLDR
The combination of diverse data sources (morphology, 16S and 28S sequences) and inclusion of unconserved regions of the alignments improved the recovery of monophyletic families, and a consensus is beginning to emerge in the recognition of three main assemblages.
Speciation and Radiation in a River: Assessing the Morphological and Genetic Differentiation in a Species Flock of Viviparous Gastropods (Cerithioidea: Pachychilidae)
TLDR
The present study has shown that there is no strict correlation between radula and shell morphology and the utilisation of substrates, thereby refuting the hypothesis that ecological speciation may have played a significant role in the Kaek River fauna.
Adaptive radiation of thalassoid gastropods in Lake Tanganyika, East Africa: morphology and systematization of a paludomid species flock in an ancient lake
TLDR
All studied species of the thalassoid species flock are actually members of the Paludomidae instead of the true Thiaridae, representing an evolutionary lineage of ancient, and most likely originally riverine Cerithioidea that predated the formation of the East African Rift system.
Uncovering an overlooked radiation: molecular phylogeny and biogeography of Madagascar's endemic river snails (Caenogastropoda: Pachychilidae: Madagasikara gen. nov.)
TLDR
Although the global patterns of pachychilid distribution have earlier been interpreted to suggest a Gondwanan origin of the family, the present study does not support this postulate and addresses the historical biogeography of the Madagascan species with respect to vicariant versus dispersalist biogeographical models.
Phylogeny and systematics of the Pachychilidae of mainland South-East Asia - novel insights from morphology and mitochondrial DNA (Mollusca, Caenogastropoda, Cerithioidea)
TLDR
Characteristic key features are a pallial oviduct with a seminal receptacle and an embryonic shell with a smooth, dome-like inflated apex and differences in the histology of the pallial Oviduct are not congruent with phylogenetic patterns as suggested by the mitochondrial trees.
Out of Asia and into India : on the molecular phylogeny and biogeography of the endemic freshwater gastropod Paracrostoma Cossmann, 1900 (Caenogastropoda: Pachychilidae)
TLDR
The origins of the Indian biota are more complex and diverse than assumed under the standard Mesozoic vicariance model and pachychilid freshwater gastropods colonized India out of South-east Asia, probably after the collision of both landmasses during the Eocene.

TLDR
A detailed characterization of Brotia sensu lato is provided and, as a basis for a taxonomic revision, comparative conchological, anatomical, and biogeographical data for the most crucial constituent species including their synonymies are provided.
Systematics, molecular genetics and historical zoogeography of the viviparous freshwater gastropod Pseudopotamis (Cerithioidea, Pachychilidae): a relic on the Torres Strait Islands, Australia

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).
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.
Phylogenetic analysis based on the morphology of viviparous freshwater clams of the family Sphaeriidae (Mollusca, Bivalvia, Veneroida)
TLDR
The analysis supports a clade comprising all species of Musculium plus Pisidium as a monophyletic group and some clades that correspond to the subgeneric divisions of the three traditionally recognized sphaeriid genera are supported.
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.
Molecular phylogeny of a circum-global, diverse gastropod superfamily (Cerithioidea: Mollusca: Caenogastropoda): pushing the deepest phylogenetic limits of mitochondrial LSU rDNA sequences.
TLDR
The molecular phylogeny shows support for the monophyly of the marine families Cerithiidae [corrected], Turritellidae, Batillariidae, Potamididae, and Scaliolidae as currently recognized and reveals that freshwater taxa evolved on three separate occasions.
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.
Evidence for convergent evolution of brooding in a unique gastropod from Lake Tanganyika: anatomy and affinity of Tanganyicia rufofilosa (Caenogastropoda, Cerithioidea, Paludomidae)
TLDR
The anatomic redescription and reinterpretation of reproductive homologies presented here revealed several features from the midgut and kidney that are informative concerning the phylogeny of Lake Tanganyika gastropods and the evolution of viviparity among limnic Cerithioidea.
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.
