The cosmopolitan family Braconidae is found in a wide range of habitats despite being composed by highly specialized parasitoids. The genus Centistes includes a total of 97 described species, distributed in the Americas, Europe, and Asia. However, for the Americas there is just a recent revision of the Costa Rican fauna, with the description of twenty-three new species, but there has not been a comprehensive work about the genus for mainland South America. In this work, we studied the variation and richness of the genus through analyses of discrete characters, linear morphometry, ratio analyses, and geometric morphometrics. A key for the known South American species is provided and 15 new species are described: C. bellus Almeida & Penteado-Dias sp. nov., C. grandis Almeida & Penteado-Dias sp. nov., C. helmuthi Shaw sp. nov., C. hemicirculus Román & Sarmiento sp. nov., C. hexagonalis Almeida & Penteado-Dias sp. nov., C. iguaquensis Román & Sarmiento sp. nov., C. itamontiensis Almeida & Penteado-Dias sp. nov., C. itatiaiaensis Almeida & Penteado-Dias sp. nov., C. lobungula Román & Sarmiento sp. nov., C. rosae Román & Sarmiento sp. nov., C. singularis Almeida & Penteado-Dias sp. nov., C. soaresi Almeida & Penteado-Dias sp. nov., C. succinum Román & Sarmiento sp. nov., C. truncatus Román & Sarmiento sp. nov., and C. tubigaster Almeida & Penteado-Dias sp. nov. The addition of these new species places Centistes as the second richest genus after Meteorus for the Euphorinae in South America.
茧蜂科是一个世界性分布的科,尽管其成员均为高度特化的寄生蜂,但它们能在广泛的栖息地中被发现。Centistes属共计有97个已描述的物种,分布于美洲、欧洲和亚洲。然而,对于美洲地区,仅有最近对哥斯达黎加动物区系的一次修订,其中描述了23个新物种,而对于南美洲大陆该属却尚无全面的研究工作。在本研究中,我们通过分析离散性状、线性形态测量、比率分析和几何形态测量来研究该属的变异和丰富度。提供了一份已知南美洲物种的检索表,并描述了15个新物种:美丽Centistes Almeida & Penteado-Dias新种、大型Centistes Almeida & Penteado-Dias新种、赫尔穆特Centistes Shaw新种、半圆形Centistes Román & Sarmiento新种、六边形Centistes Almeida & Penteado-Dias新种、伊瓜苏Centistes Román & Sarmiento新种、伊塔蒙特Centistes Almeida & Penteado-Dias新种、伊塔蒂亚伊亚Centistes Almeida & Penteado-Dias新种、叶状Centistes Román & Sarmiento新种、玫瑰Centistes Román & Sarmiento新种、奇异Centistes Almeida & Penteado-Dias新种、索阿雷斯Centistes Almeida & Penteado-Dias新种、琥珀色Centistes Román & Sarmiento新种、截形Centistes Román & Sarmiento新种以及管腹Centistes Almeida & Penteado-Dias新种。这些新物种的增加使Centistes属成为南美洲后丽茧蜂亚科中继Meteorus属之后第二丰富的属。
