Abstract

For over a decade, DNA barcoding has proven an effective modern tool in taxonomy, evolutionary biology and biodiversity research. Many new species have been discovered and described with DNA barcodes as part of their diagnostic features. Using DNA barcodes, we uncovered a number of potential species within the Tanytarsus curticornis and Tanytarsus heusdensis species complexes (Diptera: Chironomidae) and detected morphological differences a posteriori that support the description of new species. Unusually large intraspecific divergence in COI p-distance (up to 10%) was observed for two species complexes. In total, eight species new to science are described and figured: T. adustus sp. n., T. heberti sp. n., T. madeiraensis sp. n., T. pseudoheusdensis sp. n., T. songi sp. n., T. thomasi sp. n., T. tongmuensis sp. n. and T. wangi sp. n.. Tanytarsus reei and T. tamaoctavus are redescribed, and T. tusimatneous is listed as a new junior synonym of T. tamaduodecimus. The diagnostic characters of the remaining species of the complexes are discussed. Keys to males and pupae are given.

DNA条形码和形态学揭示了摇蚊科（直翅目）中未被识别的物种

十多年来，DNA条形码已被证明是分类学、进化生物学和生物多样性研究中的一种有效的现代工具。许多新物种已经被发现，并用DNA条形码作为其诊断特征的一部分进行了描述。使用DNA条形码，我们发现了短鳍短尾蠊和黑鳍短尾蝽物种复合体（直翅目：摇蚊科）中的一些潜在物种，并在后验中检测到了支持新物种描述的形态差异。在两个物种复合体中观察到COI p距离异常大的种内差异（高达10%）。总共有八个新物种被描述和描绘：T.adustusp。n.，T.hebertisp。n.，T.madeiranissp。n.，T.pseudohesdensis。n.，T.songisp。唐。n.，T.tongmuensissp。n.和T.wangisp。重新命名了Tanytarsus reei和T.tamadoctavus，并将T.tusimatneous列为T.tamadodecimus的一个新的初级同义词。讨论了配合物的其余种类的诊断特征。给出了雄性和蛹的钥匙。

期刊介绍： Insect Systematics & Evolution (ISE) publishes original papers on all aspects of systematic entomology and the evolutionary history of both extant and extinct insects and related groups. Priority is given to taxonomic revisions and phylogenetic studies employing morphological and molecular data. ISE also welcomes reviews and syntheses that can appeal to a wide community of systematic entomologists. Single species descriptions, regional checklists, and phylogenetic studies based on few taxa or single molecular markers will generally not be accepted.
