摘要

西高止山脉是一个生物多样性宝库,据报告有本地利什曼病病例。因此,在部落人口中开展了系统的沙蝇监测。本研究报告了在印度西高止山发现的一种新型沙蝇--Phlebotomus (Anaphlebotomus) ajithii n. sp.(双翅目:Psychodidae)。在印度喀拉拉邦的 Kollam、Thrissur、Idukki、Kasaragod 和 Malappuram 地区进行了一次全面的沙蝇调查。调查采用标准采集方法,历时 3 年 3 个月,涵盖室内和室外栖息地。针对线粒体细胞色素 c 氧化酶亚单位 I(COI)基因对样本进行了 DNA 条形编码,并对生成的序列进行了系统进化分析。本通讯记录并描述了沙蝇新种 Phlebotomus (Anaphlebotomus) ajithii。文中讨论了该新种与 Anaphlebotomus 亚属其他成员的形态学关系。线粒体 COI 条形码和系统进化分析证实 Ph. ajithii 的标本属于同一分类群,而与同属种之间 11.7% 的遗传距离则将其确定为一个独特的物种。西高止山以其丰富的生物多样性而闻名,但一直缺乏以沙蝇为重点的系统昆虫学调查。本研究旨在填补这一空白,报告并描述了沙蝇的一个新物种。

Report of a new species of sand fly, Phlebotomus (Anaphlebotomus) ajithii n. sp. (Diptera: Psychodidae), from Western Ghats, India
Western Ghats is a biodiversity treasure trove with reports of indigenous leishmaniasis cases. Hence, systematic sand fly surveillance was carried out among the tribal population. The present study reports a novel sand fly species, Phlebotomus (Anaphlebotomus) ajithii n. sp. (Diptera: Psychodidae), discovered in the Western Ghats of India. A comprehensive sand fly survey was conducted across the Kollam, Thrissur, Idukki, Kasaragod and Malappuram districts of Kerala, India. The survey spanned both indoor and outdoor habitats using standard collection methods over a 3-year, 3-month period. DNA barcoding of samples was performed targeting mitochondrial cytochrome c oxidase subunit I (COI) gene, and the sequence generated was subjected to phylogenetic analysis. Phlebotomus (Anaphlebotomus) ajithii, a new sand fly species, is recorded and described in this communication. The morphological relationship of the new species to other members of the subgenus Anaphlebotomus is discussed. Mitochondrial COI barcode followed by phylogenetic analysis confirmed that specimens of Ph. ajithii belong to the same taxonomic group, while a genetic distance of 11.7% from congeners established it as a distinct species. The Western Ghats, known for its rich biodiversity, has lacked systematic entomological surveys focusing on sand flies. This study aims to fill this gap and reports and describes a new species of sand fly.

期刊介绍: Parasites & Vectors is an open access, peer-reviewed online journal dealing with the biology of parasites, parasitic diseases, intermediate hosts, vectors and vector-borne pathogens. Manuscripts published in this journal will be available to all worldwide, with no barriers to access, immediately following acceptance. However, authors retain the copyright of their material and may use it, or distribute it, as they wish. Manuscripts on all aspects of the basic and applied biology of parasites, intermediate hosts, vectors and vector-borne pathogens will be considered. In addition to the traditional and well-established areas of science in these fields, we also aim to provide a vehicle for publication of the rapidly developing resources and technology in parasite, intermediate host and vector genomics and their impacts on biological research. We are able to publish large datasets and extensive results, frequently associated with genomic and post-genomic technologies, which are not readily accommodated in traditional journals. Manuscripts addressing broader issues, for example economics, social sciences and global climate change in relation to parasites, vectors and disease control, are also welcomed.
