“…Invertebrates represent >95% of all animal taxa (Cowie et al, 2017; May, 1988). Mollusca is the second most diverse invertebrate phylum after Arthropoda, with approximately 200,000 species (Ponder et al, 2019), most of which produce durable carbonate shells.…”

Natural history collections worldwide contain a plethora of mollusc shells. Recent studies have detailed the sequencing of DNA extracted from shells up to thousands of years old and from various taphonomic and preservational contexts. However, previous approaches have largely addressed methodological rather than evolutionary research questions. Here, we report the generation of DNA sequence data from mollusc shells using such techniques, applied to Haliotis virginea Gmelin, 1791, a New Zealand abalone, in which morphological variation has led to the recognition of several forms and subspecies. We successfully recovered near‐complete mitogenomes from 22 specimens including 12 dry‐preserved shells up to 60 years old. We used a combination of palaeogenetic techniques that have not previously been applied to shell, including DNA extraction optimized for ultra‐short fragments and hybridization‐capture of single‐stranded DNA libraries. Phylogenetic analyses revealed three major, well‐supported clades comprising samples from: (1) The Three Kings Islands; (2) the Auckland, Chatham and Antipodes Islands; and (3) mainland New Zealand and Campbell Island. This phylogeographic structure does not correspond to the currently recognized forms. Critically, our nonreliance on freshly collected or ethanol‐preserved samples enabled inclusion of topotypes of all recognized subspecies as well as additional difficult‐to‐sample populations. Broader application of these comparatively cost‐effective and reliable methods to modern, historical, archaeological and palaeontological shell samples has the potential to revolutionize invertebrate genetic research.

This paper presents the first comprehensive checklist of the non-marine molluscs from the western Himalaya, a region of high biodiversity and endemism. Based on faunistic surveys during 2019-2023 and published records, the paper reports 242 species belonging to 101 genera and 45 families of gastropods and bivalves, of which 168 species are endemic to the region. The paper also provides new distribution records and taxonomic notes for some species. Among the notable findings are the first records of Limax mayae, Oxyloma sp., Odhneripisidium kuiperi, Thiara aspera from India, and Bensonies jamuensis, Euaustenia cassida, Stagnicola sp. from the western Himalaya. The paper presents some species with substitutional illustrations and literature from the region for the past two centuries. Additionally, the paper also discusses the threats that non-marine molluscs face in the western Himalaya and suggests some conservation measures to protect them. The authors hope this paper will serve as a baseline for future studies on the diversity, distribution, ecology, and conservation of non-marine molluscs in the western Himalaya.
