Two Neotropical subgenera of Coelioxys Latreille are revised. The monotypic C. (Platycoelioxys) Mitchell and C. (Rhinocoelioxys) Mitchell has seven valid species; six of them (C. agilis Smith, C. barbata Schwarz & Michener, C. clypearis Friese, C. nasidens Friese, C. paraguayensis Schrottky and C. zapoteca Cresson) previously described, and one, C. platygnatha Rocha-Filho & Packer n. sp. is new from Amazonas State, Brazil. Coelioxys nasidens, previously considered a junior synonym of C. clypeata Smith, is resurrected. Coelioxys crassiceps Friese and C. excisa Friese are synonymized under C. agilis, and C. rostrata Friese is synonymized under C. paraguayensis. Nine names (C. clypeata, C. leucochrysea Cockerell, C. angustivalva Holmberg, C. doelloi Holmberg, C. blabera Holmberg, C. mesopotamica Holmberg, C. bilobata Friese, C. bilobata schenki Friese and C. bullaticeps Friese) are synonymized with C. zapoteca. In the latter species the shape of the apical margin of the clypeus of the female varies widely and, though intermediates occur among all forms, the DNA barcode sequences for the different forms are very similar. One species formerly considered as incertae sedis, C. clypearis, and one belonging to the subgenus C. (Cyrtocoelioxys) Mitchell, C. barbata, are both assigned to the subgenus C. (Rhinocoelioxys). Keys for both sexes of C. (Rhinocoelioxys), distribution maps, host and floral records, redescriptions of species and the description of a new species are provided. In the subgenus C. (Platycoelioxys), only one species, C. alatiformis Friese, is recognized with two junior synonyms: C. crassiceps Friese syn. nov. and C. spatuliventer Cockerell.
对切叶蜂属（Coelioxys Latreille）的两个新热带亚属进行了修订。单型的扁切叶蜂亚属（C. (Platycoelioxys) Mitchell）和突切叶蜂亚属（C. (Rhinocoelioxys) Mitchell）有七个有效物种；其中六个（敏捷切叶蜂C. agilis Smith、髯切叶蜂C. barbata Schwarz & Michener、唇切叶蜂C. clypearis Friese、鼻切叶蜂C. nasidens Friese、巴拉圭切叶蜂C. paraguayensis Schrottky和萨波特卡切叶蜂C. zapoteca Cresson）先前已有描述，还有一个，宽颚切叶蜂C. platygnatha Rocha-Filho & Packer新种，发现于巴西亚马逊州。鼻切叶蜂C. nasidens，先前被认为是唇切叶蜂C. clypeata Smith的次异名，现恢复为有效种。粗壮切叶蜂C. crassiceps Friese和缺刻切叶蜂C. excisa Friese被归为敏捷切叶蜂C. agilis的异名，喙切叶蜂C. rostrata Friese被归为巴拉圭切叶蜂C. paraguayensis的异名。九个名称（唇切叶蜂C. clypeata、白黄切叶蜂C. leucochrysea Cockerell、狭瓣切叶蜂C. angustivalva Holmberg、多氏切叶蜂C. doelloi Holmberg、布拉贝拉切叶蜂C. blabera Holmberg、美索不达米亚切叶蜂C. mesopotamica Holmberg、双叶切叶蜂C. bilobata Friese、申氏双叶切叶蜂C. bilobata schenki Friese和圆头切叶蜂C. bullaticeps Friese）被归为萨波特卡切叶蜂C. zapoteca的异名。在后者的物种中，雌性唇基顶端边缘的形状变化很大，尽管在所有形态之间都有中间类型存在，但不同形态的DNA条形码序列非常相似。一个先前被认为分类地位不确定的物种，唇切叶蜂C. clypearis，以及一个属于切叶蜂亚属（C. (Cyrtocoelioxys) Mitchell）的物种，髯切叶蜂C. barbata，都被归入突切叶蜂亚属（C. (Rhinocoelioxys)）。提供了突切叶蜂亚属（C. (Rhinocoelioxys)）雌雄两性的检索表、分布图、寄主和花的记录、物种重新描述以及一个新物种的描述。在扁切叶蜂亚属（C. (Platycoelioxys)）中，只认可一个物种，翼状切叶蜂C. alatiformis Friese，有两个次异名：粗壮切叶蜂C. crassiceps Friese新异名和匙腹切叶蜂C. spatuliventer Cockerell。
