BACKGROUND
Phlebotomine sand flies of the genus Trichophoromyia Barretto, 1962 are of great relevance to public health as vectors of Leishmania protozoans. A new phlebotomine species named Trichophoromyia peixotoi n. sp. is here described based on both male morphology and COI DNA barcodes.
METHODS
The sand fly specimens were collected in the Parque Nacional da Amazônia (PNA), situated in the municipality of Itaituba, state of Pará, Brazil. Morphological description was done based on 10 male specimens. Five specimens were DNA barcoded for the COI gene.
RESULTS
The morphological and molecular analyses allowed the delimitation of this new species from others of Trichophoromyia. Trichophoromyia peixotoi n. sp. is closely related to other species with aedeagal ducts > 4 times the length of the sperm pump, from which it may be distinguished by the gonocoxite bristles and paramere shape.
CONCLUSIONS
The description of T. peixotoi n. sp. brings the number of species of Trichophoromyia to 45, including 24 for Brazil. The integrative taxonomy effort through the analysis of COI barcodes proved to be effective in the species delimitation of some Trichophoromyia spp.
背景
采采蝇属的白蛉是传播原生动物利什曼原虫的重要媒介，对公共卫生具有重要意义。本文基于雄性形态和 COI DNA 条码描述了一种名为 Trichophoromyia peixotoi n. sp. 的新白蛉。
方法
在巴西帕拉州伊塔蒂巴市的亚马逊国家公园（PNA）采集了白蛉标本。根据 10 只雄性标本进行了形态描述。对 5 个标本进行了 COI 基因的 DNA 条码分析。
结果
形态学和分子分析将该新种与其他 Trichophoromyia 种区分开来。Trichophoromyia peixotoi n. sp. 与其他具有输精管长度超过精子泵 4 倍的物种密切相关，可通过肛侧板刚毛和侧尾叶的形状来区分。
结论
Trichophoromyia peixotoi n. sp. 的描述使采采蝇属的物种数量达到 45 种，其中包括巴西的 24 种。通过 COI 条码分析进行的综合分类学研究证明对一些 Trichophoromyia spp. 的物种界定是有效的。
