Abstract

Abstract Inga subnuda is one of 31 Inga species endemic to the Brazilian Atlantic Forest and is currently treated as having two subspecies (I. subnuda subsp. subnuda and I. subnuda subsp. luschnathiana). However, due to intermixed leaf and floral traits, these subspecies are difficult to morphologically distinguish. This study aimed to better understand the boundaries of these two subspecies and to test if these taxa should be treated at the species level. Morphological variation and bioclimatic data related to the two subspecies of the complex were assessed using multivariate morphometric analyses and ecological niche modeling. Different groups were recognized using morphological quantitative characters. The climatic space was similar but not identical, and recent climatic cycles that could have shaped the current distributions of the subspecies are discussed. The results of our integrative study suggest the subspecies are distinct species. Thus, we propose changing the status of I. subnuda subsp. luschnathiana to the rank of species. The new taxon is described and illustrated. Resumo Inga subnuda é uma das 31 espécies presentes na Floresta Atlântica. A morfologia foliar e floral sobreposta dificulta o estabelecimento de limites e o tratamento taxonômico atual considera Inga subnuda como uma espécie com duas subespécies.

基于形态学、生态学和古生态学资料的大西洋森林特有Inga subnuda亚种划分(豆科，杉木科，含豆纲

摘要印加亚努达(Inga subnuda)是巴西大西洋森林特有的31种印加种之一，目前被认为有两个亚种(I. subnuda subsp.)。subnuda和subnuda subsp。luschnathiana)。然而，由于叶和花的混合性状，这些亚种很难在形态上区分。本研究旨在更好地了解这两个亚种的边界，并测试这些分类群是否应该在物种水平上进行处理。利用多变量形态计量学分析和生态位模型对两个亚种的形态变化和生物气候数据进行了评估。利用形态数量特征识别不同类群。气候空间相似但不相同，并讨论了可能形成亚种当前分布的近期气候周期。我们的综合研究结果表明，亚种是不同的物种。因此，我们建议改变I. subnuda subsp的地位。Luschnathiana到物种的等级。对新分类单元进行了描述和图解。resume: Inga subnuda . uma: 31份电子文件，提交给Floresta atlntica。一种形态上的叶状或花状的孢子，难以建立或限制其处理taxonômico，通常考虑Inga subnuda como uma espacci.com as subespacimcies。我们将探讨evidências分段汇算表的不同类型，以及分段汇算表和分段汇算表的区别。如variações morfológicas e - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As - As两种特征的定量鉴定和鉴定的许可度存在táxons差异。O esparado climático与此类似，as n O idêntico, aliás s O discutidos os最近的ciclos climáticos que poderiam ter modelado a distributionalicaratual。综上所述，综上所述，综上所述，综上所述，综上所述，综上所述，综上所述，综上所述，综上所述，综上所述。luschnathiana。一种新的划界法(A -)。
