The genus Gonatoxia Karsch, which was synonymized with Dapanera Karsch by Massa (2015), is re-established. Data on habitat, biology, ecology, the acoustics and on chromosomes are provided as well as a key to the species. The male of G. immaculata Karsch and the female of G. maculata Karsch are described. G. furcata sp. n. from the Udzungwa Mountains of Tanzania and G. helleri sp. n. inhabiting coastal and lowland wet forest are newly described. All species have calling songs consisting of very short, resonant syllables, produced in species specific intervals, and with peak carrier frequencies between 13 and 24 kHz. In respect to chromosome numbers Gonatoxia species showed extreme differences (from 29 to 7) suggesting rapid evolutionary changes. G. helleri sp. n. so far is the tettigoniid species with the lowest number of chromosomes at present. Gonatoxia species may be used as bioindicators, their presence suggesting valuable habitats that are vanishing rapidly in East Africa.

有斑点的雄性、均匀的雌性和记录的 Tettigoniids 中最低的染色体数：Gonatoxia Karsch 属的回顾（直翅目，Phaneropterae）

重新建立了 Gonatoxia Karsch 属，该属被 Massa (2015) 称为 Dapanera Karsch 的同义词。提供关于栖息地、生物学、生态学、声学和染色体的数据以及物种的关键。描述了G. immaculata Karsch的雄性和G. maculata Karsch的雌性。G. furcata sp。n. 来自坦桑尼亚的 Udzungwa 山脉和 G. helleri sp。n. 栖息地沿海和低地湿林被新描述。所有物种的呼叫歌曲都由非常短的共振音节组成，以物种特定的间隔产生，峰值载波频率在 13 到 24 kHz 之间。在染色体数量方面，促性腺激素物种表现出极大的差异（从 29 到 7），表明进化变化很快。G. hereri sp. n. 迄今为止是目前染色体数量最少的tettigoniid物种。
