Mazama americana (red brocket deer) is the genus-type species (first species described for this genus) and the basis for the identity of other Mazama species. Mazama americana is one of the most abundant and widely distributed deer species in the neotropical forest. However, recent studies suggest that this taxon belongs to a species complex. Our goal was to collect an animal at the type locality (topotype) in French Guiana with the aim of characterizing the morphological (biometric, craniometric), cytogenetic (Giemsa, C-banding, G-banding and NOR) and molecular (mitochondrial DNA) features. The comparisons showed that the collected specimen was very similar morphologically to specimens from other South American populations, but it was cytogenetically and molecularly very different from any of the cytotypes already described for this species, corroborating the existence of a complex of cryptic species. The data suggest that the M. americana topotype is a different species from all the cytotypes already described in the literature and which occupy the southern region of the Amazon River. The characterization and designation of the M. americana neotype is the first step toward a taxonomic reorganization of the genus Mazama, with the potential identification of new species.

美洲M（Artiodactyla，Cervidae）的新类型的名称揭示了bro鹿物种的一种神秘的新复合体。

美洲（红bro鹿）是属类型的物种（为此属描述的第一个物种），并且是其他M间物种身份的基础。美洲az是新热带森林中数量最多，分布最广的鹿种之一。但是，最近的研究表明该分类单元属于物种复合体。我们的目标是在法属圭亚那收集一种类型局部性（拓扑型）的动物，以表征形态学（生物测定，颅骨测定），细胞遗传学（吉姆萨，C条带，G条带和NOR）和分子（线粒体DNA）的特征。特征。比较结果显示，所收集的标本在形态上与其他南美种群的标本非常相似，但是在细胞遗传学和分子学上与该物种已经描述过的任何细胞类型都有很大的不同，证实了隐性物种复合体的存在。数据表明，美洲分枝杆菌的分型是不同于文献中已经描述的所有细胞型的物种，并且占据了亚马逊河的南部地区。M. americana新类型的特征和命名是迈萨玛（Mazama）属分类重组的第一步，并有可能鉴定出新物种。
