The systematics and taxonomy of the Neotropical genus Micronycteris are not yet resolved; previous studies evidenced paraphyletic relationships, a number of potential undescribed species, and inadequate diagnostic characters. This revision focuses on the pale‐bellied members of the genus using phylogenetic and morphometric tools, an increased sample size with all recognized taxa, and an expanded geographic coverage relative to prior studies. For the genetic analyses (n = 166), four molecular markers were concatenated, one mitochondrial (cytb), one nuclear (Fgb‐I7), and two Y‐chromosomal (DBY5 and DBY7). In the Bayesian and maximum likelihood analyses, the recognized subgenera Schizonycteris, Leuconycteris, Xenoctenes, and Micronycteris were recovered as monophyletic. The pale‐bellied subgenera, Schizonycteris and Leuconycteris, were not sister clades; thus, venter coloration was not monophyletic. Leuconycteris was sister to the dark‐bellied Micronycteris, and Schizonycteris was sister to the rest of the genus. Micronycteris schmidtorum was genetically defined for the first time, and it was determined all previous phylogenetic studies used a misidentified M. minuta from Bolivia. Our results showed a sister relationship between M. schmidtorum and M. brosseti, which redefines Leuconycteris. The subgenus Schizonycteris was also redefined, and it presented two well‐supported clades from Central America and western Ecuador that are described as new species. Results are supported by a multivariate morphometric analyses (n = 114), karyological, and morphological comparisons. The taxonomic implications are discussed and emended diagnoses presented for the pale‐bellied subgenera and for M. schmidtorum.

修订大腹灰背灰霉,1866年(鳞翅目,披甲科),并描述了两个新物种

新热带属Micronycteris的系统分类学尚未得到解决。先前的研究证明了亲缘关系,许多潜在的未描述物种以及诊断特征不足。该修订版着重于使用系统发育和形态计量学工具对属的大肚成员,与所有公认分类单元一起增加的样本量以及相对于先前研究的扩大的地理覆盖范围。为了进行遗传分析(n  = 166),将四个分子标记连接起来,一个线粒体(cytb),一个核仁(Fgb- I7)和两个Y染色体(DBY5DBY7)。在贝叶斯和最大似然分析中,公认的子属裂殖体白带XenoctenesMicronycteris被回收为单系统的。苍白的亚属SchizonycterisLeuconycteris不是姐妹进化枝。因此,venter着色不是单一的。Leuconycteris是黑腹Micronycteris的姐妹,而Schizonycteris是其余属的姐妹。schmidtorum schmidtorum是首次被遗传学定义,并且确定所有以前的系统发育研究均使用了来自玻利维亚的误认的M. minuta。我们的结果表明schmidtorumBrosseti M.重新定义了LeuconycterisSchizonycteris亚属被重新定义,它呈现了来自中美洲和厄瓜多尔西部的两个得到良好支持的进化枝,被描述为新物种。结果得到多变量形态分析(n  = 114),形态学和形态学比较的支持。分类学影响进行了讨论和仔细的校勘呈现为浅腹亚属和用于诊断M. schmidtorum
