Agraecia Audinet-Serville, the type-genus of Agraeciini, comprises fifteen species names: thirteen used for extant species, one junior synonym, and one fossil. The species are morphologically very dissimilar, and were collected and described from different localities of the world. The genus was reassessed based on recently collected specimens from Brazil and Argentina as well as museum specimens. Based on morphological characteristics we re-delimit Agraecia sensu novo, keeping only two of the previously assigned species: A. punctata Saint-Fargeau & Audinet-Serville and A. dorsalis Karny. The subtribe Agraeciina subtrib. nov. is defined, which include Agraecia s. nov. and three new genera (Iaratrox Chamorro-Rengifo & Lopes-Andrade gen. nov., Starkonsa Chamorro-Rengifo & Lopes-Andrade gen. nov., and Yvelinula Chamorro-Rengifo & Lopes-Andrade gen. nov.). Three additional genera treated here, Parasubria Karny, Ragoniella Chamorro-Rengifo & Lopes-Andrade gen. nov., Redtenbachus Chamorro-Rengifo & Lopes-Andrade gen. nov. and Sylvainhugiella Chamorro-Rengifo & Lopes-Andrade gen. nov. currently remain unclassified inside Agraeciini. We desig-nate a neotype and describe the female and male for A. punctata. Bertoniella Rehn is proposed as a junior synonym of Agraecia, and Parasubria ziczac Karny as syn. nov. of Parasubria vittipes (Redtenbacher) comb. nov. The fossil species is transferred to Senexefigia† Chamorro-Rengifo & Lopes-Andrade gen. nov. We also describe two new species of Iaratrox gen. nov., I. brasilienses Chamorro-Rengifo & Lopes-Andrade sp. nov. and I. longicornia Chamorro-Rengifo & Lopes-Andrade sp. nov. The holotype of Agraecia fallax Karny nomen dubium seems to be lost and the syntypes of Agraecia festae Griffini are currently unavailable for examination, therefore, these two species are treated as incertae sedis, and should probably be transferred. A key to the studied genera is provided, as well as a key to species of Agraecia s. nov. and Iaratrox gen. nov. The calling songs of Parasubria vittipes (Redtenbacher) comb. nov. and Ragoniella pulchella (Hebard) comb. nov. are described. Numerous morphological details and some natural history aspects are discussed.
阿格雷西亚属（Agraecia）是阿格雷西ini族的模式属，包含15个物种名称：13个用于现存物种，1个次异名，1个化石物种。这些物种在形态上差异很大，采自世界不同地区并被描述。基于最近从巴西和阿根廷采集的标本以及博物馆标本对该属进行了重新评估。根据形态特征，我们重新界定了阿格雷西亚属，仅保留之前指定的两个物种：斑点阿格雷西亚（A. punctata Saint-Fargeau & Audinet-Serville）和背阿格雷西亚（A. dorsalis Karny）。定义了新的亚族阿格雷西ina亚族，包括新的阿格雷西亚属以及三个新属（新属伊阿特拉克斯属（Iaratrox Chamorro-Rengifo & Lopes-Andrade）、新属斯塔孔萨属（Starkonsa Chamorro-Rengifo & Lopes-Andrade）和新属伊夫林努拉属（Yvelinula Chamorro-Rengifo & Lopes-Andrade））。这里处理的另外三个属，即卡尔尼的副苏布里亚属（Parasubria Karny）、新属拉戈尼埃拉属（Ragoniella Chamorro-Rengifo & Lopes-Andrade）、新属雷滕巴赫属（Redtenbachus Chamorro-Rengifo & Lopes-Andrade）和新属西尔万胡吉埃拉属（Sylvainhugiella Chamorro-Rengifo & Lopes-Andrade）目前在阿格雷西ini族内仍未分类。我们指定了一个新模式标本，并描述了斑点阿格雷西亚的雌性和雄性。提议将贝托尼埃拉属（Bertoniella Rehn）作为阿格雷西亚属的次异名，以及将卡尔尼的锯齿副苏布里亚（Parasubria ziczac Karny）作为 vittipes (Redtenbacher) 新组合的副苏布里亚 vittipes 的新异名。化石物种被转移到新属森内克菲吉亚属（Senexefigia† Chamorro-Rengifo & Lopes-Andrade）。我们还描述了新属伊阿特拉克斯属的两个新物种，即巴西伊阿特拉克斯（I. brasilienses Chamorro-Rengifo & Lopes-Andrade）和长角伊阿特拉克斯（I. longicornia Chamorro-Rengifo & Lopes-Andrade）。卡尔尼的可疑名称阿格雷西亚 fallax 的模式标本似乎已丢失，而格里菲尼的阿格雷西亚 festae 的合模式标本目前无法进行检查，因此，这两个物种被视为分类地位不确定，可能应进行转移。提供了所研究属的检索表，以及新的阿格雷西亚属和新属伊阿特拉克斯属的物种检索表。描述了 vittipes (Redtenbacher) 新组合和 pulchella (Hebard) 新组合的鸣声。讨论了许多形态细节和一些自然历史方面的内容。
