What is an ‘extant’ type specimen? Problems arising from naming mammalian species‐group taxa without preserved types

ABSTRACT1. The International Code of Zoological Nomenclature allows the naming of new species without a type specimen ever having been preserved. This practice causes problems and is undesirable because if related, cryptic, sibling species are encountered later, it may not be possible either to allocate them with certainty to the earlier named species, or to determine them to be something different. 2.We hypothesised that examination of the instances in which mammalian species were named without preserved types would reveal certain problems that are not unique to them, but are encountered more frequently than when types are preserved. We also thought the Code's stipulation that preserved types are not required in the case of specimens that are no longer 'extant' would present special problems hitherto unremarked upon in the literature. 3. We conducted a review of cases involving putative new species of mammal named since 1900. These were analysed to see what special problems they present and the frequency of such problems. 4. We found that the Code's waiver of the requirement that a type specimen be deposited in a collection if the specimen is no longer extant presents numerous problems-in particular, that a living-at-large type specimen can still be 'extant' even if its whereabouts are unknown at certain times and/or it may no longer be alive. Illustrations alone being used to designate type specimens is especially problematic, owing to mammals' lack of meristic and other obvious distinguishing external characters. Hoaxes, the difficulty in determining that they are hoaxes, and various errors of taxonomic allocation appear to be especially common with names without preserved types. The Code should be revised to require preserved specimens as types for new names. Tissue samples alone for DNA analysis are not ideal for serving this purpose, but should be allowed to meet the requirement.

“…The taxonomy of mouse lemurs was subject to regular changes within the last decades (Hotaling et al, 2016; Lei et al, 2015; Rasoloarison, Weisrock, Yoder, Rakotondravony, & Kappeler, 2013; Schwitzer et al, 2013; Thiele, Razafimahatratra, & Hapke, 2013). Hence, former species names were modified to fit the latest taxonomy.…”

A major shift in diversification rate helps explain macroevolutionary patterns in primate species diversity

Primates represent one of the most species rich, wide ranging, and ecologically diverse clades of mammals. What major macroevolutionary factors have driven their diversification and contributed to the modern distribution of primate species remains widely debated. We employed phylogenetic comparative methods to examine the role of clade age and evolutionary rate heterogeneity in the modern distribution of species diversity of Primates. Primate diversification has accelerated since its origin, with decreased extinction leading to a shift to even higher evolutionary rates in the most species rich family (Cercopithecidae). Older primate clades tended to be more diverse, however a shift in evolutionary rate was necessary to adequately explain the imbalance in species diversity. Species richness was also poorly explained by geographic distribution, especially once clade age and evolutionary rate shifts were accounted for, and may relate instead to other ecological factors. The global distribution of primate species diversity appears to have been strongly impacted by heterogeneity in evolutionary rates.
