Mantodea plays a special role in the food chain as a group charismatic generalist predators. They regulate invertebrate populations while themselves being prey for many larger animals such as reptiles and birds. The present study focuses on Fench Guiana where about 78 species are known within eight families. This diversity represents a challenge for specimen identification.
The MANGF project aims at developing a DNA metabarcoding approach to facilitate and enhance the monitoring of mantises as indicators in ecological studies. As a first step towards that goal, we assembled a library of DNA barcodes using the standard genetic marker for animals, i.e. a portion of the COI mitochondrial gene. In the present contribution, we release a library including 425 records representing 68 species in eight different families. Species were identified by expert taxonomists and each record is linked to a voucher specimen to enable future morphological examination. We also highlight and briefly discuss cases of low interspecific divergences, as well as cases of high intraspecific divergences that might represent cases of overlooked or cryptic diversity.
螳螂作为一类具有魅力的广食性捕食者，在食物链中扮演着特殊角色。它们调控无脊椎动物种群数量，同时自身也是许多大型动物（如爬行动物和鸟类）的猎物。本研究聚焦于法属圭亚那，该地已知约有78个物种分属于8个科。这种多样性给标本鉴定带来了挑战。
MANGF项目旨在开发一种DNA宏条形码方法，以促进和加强对螳螂作为生态研究指标的监测。作为实现该目标的第一步，我们使用动物的标准遗传标记，即细胞色素氧化酶亚基I（COI）线粒体基因的一部分，组装了一个DNA条形码文库。在本论文中，我们发布了一个包含425条记录的文库，这些记录代表了8个不同科的68个物种。物种由专业分类学家鉴定，每条记录都与一个凭证标本相关联，以便未来进行形态学检查。我们还强调并简要讨论了种间差异低的情况，以及可能代表被忽视或隐性多样性情况的种内差异高的情况。
