The transmission of cutaneous leishmaniasis (CL) is of public health concern in Sri Lanka. The parasite Leishmania donovani is reported to be the causative agent for CL in Sri Lanka. However there is no report on the vector of CL in the country. Phlebotomus argentipes sensu lato is the well known vector of L. donovani which causes visceral leishmaniasis (VL) in the nearby South India. The taxon Ph. argentipes previously reported to occur as a species complex comprising of two morphospecies namely A and B. The taxonomy of the Argentipes complex was reassessed recently and reported to have three species viz. Phlebotomus glaucus, Ph. argentipes sensu stricto and Ph. annandalei. A study was carried out in Jaffna mainland, where three CL patients have been recorded, and two associated islands in northern Sri Lanka to record the presence of the members of the Argentipes complex. Sandflies were collected using human landing and cattle baited collections. Collected samples were analyzed based on reported morphometric and meristic characteristics. The study revealed the presence of all three members of the complex in which Ph. glaucus and Ph. argentipes s.s. are reported for the first time in Sri Lanka.
皮肤利什曼病（CL）的传播在斯里兰卡是一个公共卫生问题。据报道，杜氏利什曼原虫是斯里兰卡CL的病原体。然而，该国尚无关于CL传播媒介的报道。宽翅白蛉复合体是在附近的南印度引起内脏利什曼病（VL）的杜氏利什曼原虫的著名传播媒介。以前报道宽翅白蛉分类单元是一个包含两个形态种（即A和B）的物种复合体。最近对宽翅白蛉复合体的分类进行了重新评估，报告称有三个物种，即苍白白蛉、狭义宽翅白蛉和安南白蛉。在贾夫纳大陆（已记录到3例CL患者）以及斯里兰卡北部的两个相关岛屿开展了一项研究，以记录宽翅白蛉复合体成员的存在情况。使用人饵诱捕法和牛饵诱捕法收集白蛉。根据报道的形态测量和可数特征对收集的样本进行分析。该研究揭示了该复合体所有三个成员的存在，其中苍白白蛉和狭义宽翅白蛉是在斯里兰卡首次被报道。
