(red brocket deer) is the genus-type species (first species described for this genus) and the basis for the identity of other species. 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 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 neotype is the first step toward a taxonomic reorganization of the genus , with the potential identification of new species.
红短角鹿是该属的模式种（该属描述的首个物种），也是其他物种身份认定的基础。它是新热带森林中数量最为丰富、分布最为广泛的鹿种之一。然而，近期研究表明，这个分类单元属于一个物种复合体。我们的目标是在法属圭亚那的模式产地（原产地）采集一只动物，以表征其形态学（生物测量、颅骨测量）、细胞遗传学（吉姆萨染色、C带、G带和核仁组织区）和分子学（线粒体DNA）特征。比较结果显示，所采集的标本在形态上与其他南美种群的标本非常相似，但在细胞遗传学和分子学上与该物种已描述的任何细胞型都有很大差异，这证实了隐性物种复合体的存在。数据表明，模式产地的标本与文献中已描述的、占据亚马逊河南部地区的所有细胞型都属于不同的物种。新模标本的表征和指定是该属分类重组的第一步，有可能识别出新物种。
