Cephalophlugis Gorochov, 1998 is a Neotropical genus of predatory katydids with two valid species, Cephalophlugis cephalotes (Bolvar, 1888) (from So Paulo, Brazil) and Cephalophlugis setosa Gorochov, 2012 (from Sucumbios, Ecuador). Herein, we describe a third species of the genus, Cephalophlugis gaucho sp. nov., from Rio Grande do Sul, Brazil. This species is easily distinguished from the others by the color of the hind wings and the number of spurs on the fore and middle legs. The calling song is composed of a long phrase with a series of syllables that vary in emission rate from beginning to end, with a dominant frequency of 23.43 0.6 (22.1224.37, n=11) kHz. So far, the species sings at the lowest frequency among the Phlugidini. From the chromosomal perspective, C. gaucho sp. nov. presents the karyotype 2n=31, X0, with the complement conserved within Meconematinae.
1998 年，Gorochov 建立了 Cephalophlugis 属，这是一个新热带地区的掠食性螽斯，有两个有效物种，即 Cephalophlugis cephalotes (Bolvar, 1888)（来自巴西圣保罗州）和 Cephalophlugis setosa Gorochov, 2012（来自厄瓜多尔苏昆比奥斯省）。本文描述了该属的第三个物种，Cephalophlugis gaucho sp. nov.，来自巴西的南里奥格兰德州。该物种与其他物种的区别在于后翅的颜色和前、中足的刺的数量。其鸣叫声由一个长的短语组成，短语由一系列在发射率上从开始到结束变化的音节组成，主频为 23.43 0.6（22.1224.37，n=11）kHz。到目前为止，该物种的鸣声是在 Phlugidini 中频率最低的。从染色体的角度来看，C. gaucho sp. nov. 具有 2n=31，XO 的染色体核型，其基因组在 Meconematinae 中是保守的。
