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 Brunner von Wattenwyl, 1878 from Brazil. The male diploid number of Brunner von Wattenwyl, 1891 and Brunner von Wattenwyl, 1878 is 2n♂= 31, whereas 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, , can be chromosomally distinguished from the Cerrado biome species and , due to the difference in chromosome number (2n♂= 29 and 2n♂= 31, respectively).
扇螽亚科是螽斯科最大的亚科，分布于全球。关于这一类群的细胞遗传学研究很少，例如阿尼亚拉属，该属仅有两个已进行核型分析的物种。当前的研究旨在对来自巴西的1878年布鲁纳·冯·瓦滕维尔所描述的三个物种进行细胞遗传学分析。1891年布鲁纳·冯·瓦滕维尔所描述的物种和1878年布鲁纳·冯·瓦滕维尔所描述的物种的雄性二倍体数为2n♂ = 31，而1878年布鲁纳·冯·瓦滕维尔所描述的另一个物种的雄性二倍体数为2n♂ = 29。这三个物种具有X0性染色体系统和端/近端着丝粒染色体形态。在潘塔纳尔生物群落中发现的唯一物种，可以根据染色体数目差异（分别为2n♂ = 29和2n♂ = 31）与塞拉多生物群落的物种和在染色体上加以区分。
