“…However, following discussion between the Publishers and ourselves (as Editor-in-Chief and Corresponding Editor, respectively), an exception is made here for the paper of Richling and Bouchet (2013). This unusual step has been taken as that paper serves to emphasise, to all conservation biologists and biodiversity scientists, that recorded historical species extinctions will always underestimate the true situation in diverse groups of organisms.…”

“…The proportion of such undescribed extinct species in collections is unknown, but cases have been demonstrated. Richling and Bouchet (2013), in this issue, cite some examples drawn from different groups of organisms.…”

“…This is commonplace in palaeontology, but rarely considered for historical extinctions except in the notable case of bird remains on Pacific Islands (Pimm et al 2006). The case involving snail shells (Richling and Bouchet 2013), shows just how important this can be in some other groups of less well-studied organisms.…”

The discovery of historically extinct, but hitherto undescribed, species: an under-appreciated element in extinction-rate assessments

Estimates of the numbers of species that have become extinct during historic times may need to be reconsidered in view of issues that may not factor highly in academic consciousness. For example, there are (a) species that may have gone extinct since their collection, yet were never described, (b) species now extinct of which there are extant durable remains but that have not yet been collected or described, and (c) organisms that may have been dependent on species that are now extinct. The case of overlooked species that have become extinct in historic times is exemplified by the paper of Richling and Bouchet in this issue of Biodiversity and Conservation. This paper also emphasizes the need for detailed taxonomic study as a foundation for biodiversity conservation. However, as a matter of policy, the journal does not currently include articles with descriptions of novel taxa, but an exception is made here because of the importance of the phenomenon of extinction before description and to stress the role of taxonomy in biodiversity conservation, both being issues not always widely appreciated by conservation biologists and biodiversity scientists. Based on preserved shells, Richling and Bouchet report a radiation of helicinid land snails (nine new species and one previously described), from a group of Pacific islands, with eight of the nine new species and the single previously described species appearing to be extinct.

“…The spectacularly diverse assemblages of land snails on these islands have been particularly heavily affected, with many species already extinct and the remaining fauna disappearing rapidly (Lydeard et al, 2004;Régnier et al, 2009Régnier et al, , 2015Richling and Bouchet, 2013;Sartori et al, 2014). Among the Pacific islands, the most species-rich land snail fauna is that of the Hawaiian Islands, with more than 750 described species, over 99% of them endemic to the archipelago and many to single islands (Cowie et al, 1995).…”

Revision of Partulidae (Gastropoda, Stylommatophora) of Palau, with description of a new genus for an unusual ground-dwelling species

We describe a new stylommatophoran land snail of the family Partulidae from Palau. The new species has a combination of morphological and ecological characters that do not allow its placement in any existing partulid genus, so we describe a new genus for it. The new genus is characterized by a large (18–23 mm) obese-pupoid shell; smooth protoconch; teleoconch with weak and inconsistent, progressively stronger, striae; last half of body whorl not extending beyond the penultimate whorl; widely expanded and reflexed peristome; relatively long penis, with longitudinal pilasters that fuse apically into a fleshy ridge that divides the main chamber from a small apical chamber; and vas deferens entering and penial-retractor muscle attaching at the apex of the penis. Unlike all other partulids, the new species is strictly associated with rocks in contact with the ground. Comparing the other three Palauan species – currently assigned to Partula – to our new genus and to other partulids makes it clear that they require their own genus because their morphology is quite different from that of true Partula and from that of all other genera. Hence, we resurrect the name Palaopartula Pilsbry for these snails.
