摘要
研究了来自中国的四个形态上相似的Bradysia hilaris属物种。在中国东部浙江进行的一项基于DNA元条码的双翅目多样性研究中,发现了一个超丰富的鞘翅目物种。该研究还发现了一个新种--Bradysia tianmuensis Du & Huang sp.nov.,以及一个形态相似的种--Bradysia curvula Du & Huang sp.nov.。这两个新种在形态上与中国西部贵州的 Bradysia noduspina(杨、张、杨,1993 年)的主模式相当相似。然而,B. noduspina 的副样似乎与主样不同,并被确定为科学上的新种,即 Bradysia chikunae Du & Huang sp.本研究提供了 Bradysia hilaris 组所有 31 条 COI 序列的系统发生树。和 Bradysia curvula Du & Huang sp.nov.为科学新种,因此对这四个物种进行了描述或重新描述,并附有详细的生境图像和其他有助于确定的特征。
Morphology and DNA barcodes of four species of Bradysia hilaris group from China (Diptera, Sciaridae)
Four morphologically allied species of the Bradysia hilaris group were studied from China. In a DNA metabarcoding based dipteran diversity study in Zhejiang, eastern China, a hyper-abundant sciarid species was discovered. It was further recognized in this study to be new to science, Bradysia tianmuensis Du & Huang sp. nov., as well as a morphologically similar species, Bradysia curvula Du & Huang sp. nov. Both new species were found to be fairly similar morphologically to the holotype of Bradysia noduspina Yang, Zhang & Yang, 1993 from Guizhou in western China. However, the paratype of B. noduspina appeared to be different from the holotype and determined to be new to science, Bradysia chikunae Du & Huang sp. nov. A phylogenetic tree of all the available 31 COI sequences of the Bradysia hilaris group was provided. Molecular work conducted in the current study also supports Bradysia tianmuensis Du & Huang sp. nov. and Bradysia curvula Du & Huang sp. nov. as new to science thus the four species were described or redescribed accompanied by detailed imagery of habitus and other characters useful for determination.
期刊介绍:
Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
