The option of describing new taxa using photographs as proxies for lost or escaped
('unpreserved') type specimens has been rarely used but is now undergoing renewed …

Along the Mediterranean coast of the Iberian Peninsula, great species diversity is thought to
exist, but our knowledge of Iberian polyclads is, in fact, very limited. This study contributes to …

Biological type specimens are a particular kind of voucher specimen stored in natural history
collections. Their special status and practical use are discussed in relation to the description …

Most of the European polyclad species were described after material was collected from the
