“…A new genus, however, was defined for "Marmosa" canescens by Voss and Jansa [47], and some new genera were later described for two clades previously suppressed by synonymy within Gracilinanus [48] [49]. Finally, after the last revision of genus Marmosa, Micoureus, which was previously considered a separate genus, was moved into Marmosa as a subgenus [50].…”

Marsupials have been the subjects of studies of both experimental and natural infections with different species of Leishmania in the Americas as well as Australia. Over a century has passed since the first description of a mammal being infected with Leishmania and since then several reviews have been published on the systematics of the parasites as well as their hosts. Consequently, an update of this information is needed in order to assure correct identification of the species involved in each case. A comprehensive review was undertaken and included most of the records of marsupials being infected with Leishmania sp. Emphasis was placed on parasitological, eco epidemiological and taxonomic information of both the parasites and mammalian hosts. The clinical profiles of the infections varied from severe, which principally occurred in experimentally infected animals, to asymptomatic, which was typical of natural infections. Marsupials must be considered one of the most important groups of mammalian hosts of Leishmania sp. Important factors, such as their ancient origin, wide geographical distribution and susceptibility to infections by different species of Leishmania, but with considerable resistance to the disease, could indicate that didelphids play a key role in the evolution of Leishmania in the New World.

“…The genus as a whole has never been revised, although taxonomic analyses of specimens collected in the course of regional faunal surveys have contributed numerous insights (Mustrangi and Patton, 1997;Voss et al, 2001Voss et al, , 2004Voss et al, , 2013Díaz-Nieto et al, 2011;García et al, 2014). The current classification formally recognizes 17 valid species of Marmosops, a total that includes the 15 species recognized by Gardner and Creighton (2008) and two others subsequently described as new (Voss et al, 2013;García et al, 2014).…”

“…Black-masked, longtailed, and pouchless, they were classified for many years in the genus Marmosa along with other superficially similar taxa (e.g., by Tate, 1933;Cabrera, 1958). However, subsequent morphological and molecular research (reviewed by Voss et al, 2004;Voss and Jansa, 2003) has shown that the species referred to Marmosops by , together with those later referred to the genus by Gardner and Creighton (1989), form a strongly supported monophyletic group that is not closely related to Marmosa (sensu stricto). Instead, Marmosops is now placed in the didelphine tribe Thylamyini, a clade that also includes Chacodelphys, Cryptonanus, Gracilinanus, Lestodelphys, and Thylamys (Voss and Jansa, 2009).…”

Identification of marsupials from southern Brazil using microstructure of guard-hairs. Biota Neotrop. 11(3): http://www.biotaneotropica.org.br/v11n3/en/ abstract?identification-key +bn03111032011Abstract: The analysis of mammalian hairs is a non-invasive technique that may help in the identification of Brazilian marsupials. Our objective was to identify microscopic patterns of marsupial guard-hairs (cuticle and medulla) from species with occurrence in the state of Rio Grande do Sul, southern Brazil. We also present a hair-based identification key for this group. Specifically for Monodelphis, a still taxonomically obscure genus that needs revision, we present detailed description of observed hair patterns. We obtained the analyzed material by collecting hair samples of marsupials captured in field or else deposited in different zoological collections. We identified hair patterns of ten marsupial species: Caluromys lanatus, Chironectes minimus, Didelphis aurita, Didelphis albiventris, Cryptonanus guahybae, Gracilinanus agilis, Gracilinanus microtarsus, Lutreolina crassicaudata, Micoureus paraguayanus and Philander frenatus. Individuals of the Monodelphis genus were analyzed together, considered as part of the dimidiata group. We found three distinct patterns for this group, suggesting the possible occurrence of a third species besides the two already recognized (M. brevicaudis and M. dimidiata). These morphs show distinct distribution in the state, with some degree of distribution overlap. The analysis of microscopic patterns of mammal hairs allowed the successful identification of the great majority of marsupials that occur in the Rio Grande do Sul state. Our results suggest that the two Monodelphis species of the dimidiata group might occur with a distinct distribution in the state, one of them occupying mainly the northern part and the other one the eastern region, with some overlap in the central part of the state. Resumo: A análise dos padrões microscópicos de pelos de mamíferos é uma técnica não-invasiva que pode auxiliar na identificação dos marsupiais brasileiros. O objetivo deste trabalho foi identificar padrões microscópicos dos pelos-guarda (cutícula e medula) de marsupiais ocorrentes no Rio Grande do Sul (RS), propondo uma chave dicotômica para sua identificação a partir dessas estruturas. Além disso, nós apresentamos, com detalhes, os padrões tricológicos de espécimes do gênero Monodelphis, um gênero ainda taxonomicamente obscuro que requer revisão no RS. Obtivemos o material analisado por meio da coleta de pelos de marsupiais capturados em campo ou provenientes de coleções de diferentes instituições. Identificamos os padrões dos pelos de dez espécies de marsupiais: Caluromys lanatus, Chironectes minimus, Didelphis aurita, Didelphis albiventris, Cryptonanus guahybae, Gracilinanus agilis, Gracilinanus microtarsus, Lutreolina crassicaudata, Micoureus paraguayanus e Philander frenatus. Os indivíduos do gênero Monodelphis foram analisados em conjunto, como parte do grupo dimidiata. Encontramos três padrõe...
