Correct species identification is the basis of ecological studies. Nevertheless, morphological examination alone may not be enough to tell species apart. Here, our integrated molecular and morphological studies demonstrate that the relatively widespread and common neotropical parasitoid wasp Pimpla croceipes Cresson, 1874 (Hymenoptera: Ichneumonidae: Pimplinae) actually consists of two distinct species. The name Pimpla molesta (Smith, 1879), stat. rev. is available for the second species. The two species were identified by DNA barcoding and minor differences in morphology and colouration. Our results support the previous notions that DNA barcoding can complement morphological identification and aid the discovery of cryptic species complexes.
正确的物种鉴定是生态学研究的基础。然而，仅靠形态学检查可能不足以区分物种。在此，我们综合分子和形态学研究表明，相对广泛分布且常见的新热带寄生蜂克氏普姬蜂Pimpla croceipes Cresson，1874（膜翅目：姬蜂科：普姬蜂亚科）实际上由两个不同的物种组成。第二个物种可用名为Pimpla molesta（Smith，1879），新定的名称。这两个物种通过DNA条形码以及形态和颜色上的细微差异得以鉴定。我们的结果支持了之前的观点，即DNA条形码可以补充形态学鉴定并有助于发现隐存物种复合体。
