description | Morphology has been used to establish interspecific limits in echimyid rodents. However, using only morphology can be problematic, especially for polymorphic or morphologically cryptic species. Recently, combined data sources have been used to recognize and delimit species and have proven to be especially useful for taxonomic resolutions. Makalata is a taxonomically problematic genus that needs revision. Currently, two species are recognized: M. didelphoides and M. macrura. A third species, M. obscura, is considered questionable. Molecular studies demonstrate that diversity in the genus has been underestimated. In the present study, we identified 14 subclades representing potential species in the genus Makalata using molecular and cytogenetic data. Analysis of species delimitation corroborated this hypothesis. Four lineages in the Guiana Shield, currently considered to be a single taxonomic entity in the literature (M. didelphoides) based only on morphology, were shown to be potential cryptic species, differentiated only by molecular and karyotype data. We verified that the name M. didelphoides cannot be applied to any clade or museum specimen without a genetic approach and sequencing of the holotype. We present an amended diagnosis for M. macrura through examination of the original description, sequencing, and karyotype of topotypic samples allowed us to associate with the name M. macrura represented by subclade I in this study. Karyotype data proved to be a powerful tool in differentiating the Makalata species according to different combinations of diploid number (2n) and fundamental number, as for other genera of spiny tree‐rats. Our results demonstrate a heterogeneous status for Makalata, highlighting the importance of using multiple tools to determine the taxonomy of this group and reinforcing the importance of molecular and chromosomal data added to the morphological data to obtain a more accurate picture of the taxonomic diversity of this and other small mammal genera.

Resumo
A morfologia tem sido usada para estabelecer limites interespecíficos em roedores equimídeos. No entanto, usar apenas a morfologia pode ser problemático, especialmente para espécies polimórficas ou morfologicamente crípticas. Recentemente, fonts de dados combinadas foram usadas para reconhecer e delimitar espécies e se mostraram especialmente úteis para resoluções taxonômicas. Makalata é um gênero taxonomicamente problemático que precisa de revisão. Atualmente, duas espécies são reconhecidas: M. didelphoides e M. macrura. Uma terceira espécie, M. obscura, é considerada questionável. Estudos moleculares demonstram que a diversidade no gênero foi subestimada. No presente estudo, identificamos 14 subclados representando potenciais espécies para o gênero Makalata usando dados moleculares e citogenéticos. A análise da delimitação de espécies corroborou essa hipótese. Quatro linhagens do Escudo das Guianas, atualmente consideradas uma única entidade taxonômica na literatura (M. didelphoides) com base apenas na morfologia, mostraram‐se potenciais espécies crípticas, diferenciadas apenas por dados moleculares e cariotípicos. Verificamos que o nome M. didelphoides não pode ser aplicado a nenhum clado ou espécime de museu sem uma abordagem genética e sequenciamento do holótipo. Apresentamos uma diagnose emendada para M. macrura através do exame da descrição original, sequenciamento e cariótipo de amostras topotípicas que nos permitiu associar ao nome M. macrura representado pelo subclade I neste estudo. Os dados citogenéticos provaram ser uma ferramenta importante na diferenciação das espécies de Makalata a partir da combinação de diferentes números diplóides (2n) e números fundamentais (FN), como para outros gêneros de ratos‐de‐espinho arborícolas. Nossos resultados demonstram um status heterogêneo para Makalata, destacando a importância do uso de múltiplas ferramentas para determinar a taxonomia deste grupo e reforça a importância da análise conjunta de dados moleculares e cromossômicos aos dados morfológicos para se obter um quadro mais preciso da diversidade taxonômica deste e de outros gêneros de pequenos mamíferos.</description><identifier>ISSN: 0947-5745</identifier><identifier>EISSN: 1439-0469</identifier><identifier>DOI: 10.1111/jzs.12573</identifier><language>eng</language><publisher>Berlin: Hindawi Limited</publisher><subject>Brazilian Amazon ; Cryptic species ; cytogenetic ; Cytogenetics ; Diagnosis ; Diploids ; echimyid rodents ; Fonts ; Gene sequencing ; Genera ; Guiana Shield ; Karyotypes ; Makalata ; Meta-analysis ; molecular genetic ; Morphology ; Species ; species delimitation ; taxonomic diversity ; Taxonomic revision ; Taxonomy</subject><ispartof>Journal of zoological systematics and evolutionary research, 2021-11, Vol.59 (8), p.2387-2409</ispartof><rights>2021 Wiley-VCH GmbH</rights><rights>Copyright © 2021 Blackwell Verlag GmbH</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><cites>FETCH-LOGICAL-c2573-473aab7784f0511f5b32f6f937b606c7a5a0cae40efcab163c40f3febf1836843</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1111%2Fjzs.12573$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1111%2Fjzs.12573$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,780,784,1416,27922,27923,45572,45573</link.rule.ids></links><search><creatorcontrib>Miranda, Cleuton Lima</creatorcontrib><creatorcontrib>Nunes, Mario da Silva</creatorcontrib><creatorcontrib>Farias, Izeni Pires</creatorcontrib><creatorcontrib>Silva, Maria Nazareth F. da</creatorcontrib><creatorcontrib>Rossi, Rogério Vieira</creatorcontrib><creatorcontrib>Eler, Eduardo</creatorcontrib><creatorcontrib>Feldberg, Eliana</creatorcontrib><creatorcontrib>da Silva, Raimundo Darley Figueiredo</creatorcontrib><creatorcontrib>de Oliveira, Tadeu Gomes</creatorcontrib><creatorcontrib>Nagamachi, Cleusa Yoshiko</creatorcontrib><creatorcontrib>Pieczarka, Julio Cesar</creatorcontrib><title>A molecular and chromosomic meta‐analysis approach and its implications for the taxonomy of the genus Makalata Husson, 1978 (Rodentia, Echimyidae) including an amended diagnosis for M. macrura (Wagner, 1842)</title><title>Journal of zoological systematics and evolutionary research</title><description>Morphology has been used to establish interspecific limits in echimyid rodents.
