Phaneropterinae is the largest subfamily of Tettigoniidae, distributed across the globe. There are few cytogenetic studies regarding this group, as in the case of the genus group Aniarae, which represents only two karyotyped species. The current study aims to analyze cytogenetically three species of Hyperophora Brunner von Wattenwyl, 1878 from Brazil. The male diploid number of Hyperophoraminor Brunner von Wattenwyl, 1891 and Hyperophoramajor Brunner von Wattenwyl, 1878 is 2n♂= 31, whereas Hyperophorabrasiliensis Brunner von Wattenwyl, 1878 has shown 2n♂= 29. These three species possess an X0 sex chromosome system and telo/acrocentric chromosome morphology. The only species found in the Pantanal biome, H.brasiliensis, can be chromosomally distinguished from the Cerrado biome species H.major and H.minor, due to the difference in chromosome number (2n♂= 29 and 2n♂= 31, respectively).

1878年Hyperophora Brunner von Wattenwyl的三种物种的核型（Tettigoniidae，Phaneropterinae）使形态相似的物种得以区分。

Phaneropterinae是Tettigoniidae的最大亚科，分布在全球各地。关于该组的细胞遗传学研究很少，如属Aniarae属，仅代表两个核型种。目前的研究旨在通过细胞遗传学分析来自巴西的1878年Hyperophora Brunner von Wattenwyl的三种物种。Hyperophoraminor Brunner von Wattenwyl，1891年和Hyperophoramajor Brunner von Wattenwyl，1878年的男性二倍体数为2n♂= 31，而Hyperophorabrasiliensis Brunner von Wattenwyl，1878年的男性二倍体数为2n♂=29。这三个物种具有X0性染色体系统和telo /顶体染色体形态。在潘塔纳尔生物群系H.brasiliensis中发现的唯一物种可以在染色体上与Cerrado生物群系H.major和H.minor区分，
