摘要

物种灭绝现象在全球范围内不断增加；因此，快速盘点地球上的生物多样性变得越来越重要。由于昆虫在动物群中所占的比例最高，并发挥着关键的生态作用，因此迫切需要研究昆虫的生物多样性并加速物种发现，尤其是那些未被充分研究的昆虫类群，也被称为 "黑暗类群"。萤火虫科（双翅目）是 "黑暗类群 "的一个很好的例子，特别是 Megaselia Rondani 属。由于仅用形态学方法可能不够精确且速度较慢，而仅用分子学方法往往又不够充分且容易出错，因此使用综合方法是描述超多样化黑暗类群的最佳方法。在此，我们采用大规模综合分类法（LIT），根据DNA条形码将9000种巨细胞藻分类为277个推定物种。每个聚类都通过了聚类与形态学不一致指数（最大 p-距离、稳定性指数）的预测评估，并对一部分标本进行了形态学检查。我们利用 Chao1 进行了物种估计，结果表明我们数据集的物种丰富度增加了 15%。由于这一估计主要基于德国南部的样本，因此随着地理取样范围的扩大，物种数量可能会增加。尽管德国的昆虫动物群是欧洲最著名的昆虫动物群之一，而且对噬虫目昆虫的研究已有一百多年的历史，但这是对该分类群研究的一大进步。
