The genera Cestromoecha and Poreuomena of the tribe Poreuomenini in Phaneropterinae are revised and new generic characters are given for both genera, and six new species are described in Poreuomena. The newly described species are P. biaculeatasp. nov., P. ealasp. nov., P. gracilicercatasp. nov., P. ivorianasp. nov., P. matthaeisp. nov., and P. tshuapasp. nov. Based on characters defining the two genera, three species so far listed under Cestromoecha are transferred to Poreuomena: P. crassipes Karsch, 1890, P. laeglae (Massa, 2015), and P. magnicerca (Massa, 2013). One species of Cestromoecha, C. mundamensis Karsch, 1896, is synonymised with C. tenuipes (Karsch, 1890) since no morphological differences were detected between the type specimens. Thus, two species remain with Cestromoecha, and Poreuomena now contains 16 species. Morphological closely-related species of Poreuomena suggest rapid speciation in the Congo Basin due to several expansions and shrinkages of the Guineo-Congolian forest belt since the Oligocene. At least two different morphological lineages are discernible. On the other hand the genus Cestromoecha Karsch, 1893 is a species-poor taxon.

几内亚-刚果丛林cri部落的生物地理和进化方面：修订Cestromoecha Karsch属（1893年）和Poreuomena Brunner von Wattenwyl（1878年），并描述新物种（直翅目，Tettigoniidae，Phaneropterinae）

修订了翼翅目中波雷奥门尼尼部落的Cestromoecha和Poreuomena属，并为其赋予了新的通用性状，并在Poreuomena中描述了六个新种。新描述的物种是P. biaculeatasp。十一月，P。ealasp。十一月，P。gracilicercatasp。十一月，P。ivorianasp。十一月，P。matthaeisp。十一月号和P. tshuapasp。十一月 根据定义两个属的特征，到目前为止，在Cestromoecha下列出的三个物种已转移到Poreuomena：P。crassipes Karsch，1890年，P。laeglae（Massa，2015年）和P. magnicerca（Massa，2013年）。Cestromoecha，C. mundamensis Karsch，1896的一种种与C. tenuipes（Karsch，1890）同义，因为在类型标本之间未检测到形态学差异。因此，Cestromoecha仍然有两个物种，而Poreuomena现在包含16个物种。由于渐新世以来几内亚-刚果森林带的几次扩张和收缩，形态紧密相关的波雷科姆纳物种表明刚果盆地的物种迅速形成。至少可以识别两个不同的形态谱系。另一方面，Cestromoecha Karsch属（1893）是物种贫乏的分类群。
