Using Lauraceae as a study case, we aimed in this article to: (i) delimit areas of endemism in the Espinhaço Range, Brazil; (ii) compare these areas of endemism with those previously delimited, as well as with the centres of endemism; (iii) evaluate the association between areas of endemism and vegetation types; and (iv) classify the areas of endemism according to the International Code of Area Nomenclature (ICAN). Based on a recent survey of 99 species from the Espinhaço Range, our dataset consisted of 34 endemic species belonging to nine genera. Following previous studies, we performed parsimony analysis of endemicity (PAE) using a grid square size of 0.5° × 0.5°. We delimited four areas of endemism of Lauraceae: (i) Antônio dos Santos, (ii) Conceição do Mato Dentro, (iii) Itambé do Mato Dentro, and (iv) Rio de Contas; and confirmed six previously delimited areas of endemism: (i) Southern MG, (ii) Southern Mountains Complex, (iii) Conceição do Mato Dentro, (iv) Diamantina Plateau, (v) Serra do Cabral, and (vi) Chapada Diamantina. The areas of endemism Conceição do Mato Dentro, Serra do Cabral, Diamantina, and Serra do Cipó were classified as subdistricts in the Diamantina Plateau district of the Southern Espinhaço province. We summarized and mapped all areas of endemism corresponding to the provinces, districts, and subdistricts that cover the Espinhaço Range. Areas of endemism and centres of endemism are contrasted. Finally, we highlight that the biogeographic studies along this mountain range should embrace higher taxa with representative species in different types of vegetation in order to enrich the majority of the endemism studies mainly concentrated on the campo rupestre. Unusual distribution patterns, diversity of vegetation types, and the presence of restricted species and monophyletic groups open up opportunities to carry out integrative studies concerning the biogeographic regionalization of the ER at multiple spatio-temporal scales.

月桂科特有区域：巴西埃斯皮尼亚索山脉生物地理区域化的新见解

以月桂科为研究案例，我们在本文中旨在： (i) 划定巴西埃斯皮尼亚索山脉的特有区域；(ii) 将这些地方性地区与以前划定的区域以及地方性中心进行比较；(iii) 评估特有区域与植被类型之间的关联；(iv) 根据国际区域命名法 (ICAN) 对特有区域进行分类。根据最近对埃斯皮尼亚索山脉 99 个物种的调查，我们的数据集包括属于 9 个属的 34 个特有物种。在之前的研究之后，我们使用 0.5° × 0.5° 的网格正方形大小进行了流行性 (PAE) 的简约分析。我们划定了四个月桂科特有的区域：(i) Antônio dos Santos，(ii) Conceição do Mato Dentro，(iii) Itambé do Mato Dentro，和 (iv) Rio de Contas；并确认了六个先前划定的特有区域：(i) 南部 MG，(ii) 南部山脉综合体，(iii) Conceição do Mato Dentro，(iv) Diamantina Plateau，(v) Serra do Cabral，和 (vi) Chapada Diamantina。Conceição do Mato Dentro、Serra do Cabral、Diamantina 和 Serra do Cipó 的特有地区被归类为埃斯皮尼亚索省南部 Diamantina Plateau 区的分区。我们总结并绘制了与涵盖埃斯皮尼亚索山脉的省、区和分区相对应的所有地方性地区。地方性地区和地方性中心形成对比。最后，坎波鲁佩斯特雷 不寻常的分布模式、植被类型的多样性以及受限物种和单系群的存在为在多个时空尺度上开展关于 ER 生物地理区域化的综合研究提供了机会。
