Most sand fly species are located in the Americas; some act as vectors of leishmaniasis and other human diseases. In Bolivia, about 25% of Neotropical species have been identified, and only a few have been implicated as vectors of cutaneous and visceral leishmaniasis. A new species of anthropophilic sand fly from the sub-Andean region of Alto Beni is described herein.
A large systematic entomological survey was carried out in a subtropical humid forest located in the Marimonos mountain range, at around 900 m altitude, in the municipality of Palos Blancos, Sud Yungas Province, Department of La Paz, Bolivia. Sand flies were captured over a period of 26 months between January 1982 and February 1984, at the ground and canopy level, using both CDC light traps and protected human bait. A total of 24,730 sand flies were collected on the ground, distributed in 16 species, and 3259 in the canopy, with eight species. One of these species was labeled as Pintomia (Pifanomyia) nevesi, although certain morphological features allowed us to doubt that it was that taxon. To define the identity of this sand fly, a re-evaluation (this work) was recently carried out through morphological analyses and measurements of the available specimens mounted on Euparal, previously labeled as Pi. (Pif.) nevesi.
Based on the morphological traits and measurements, the re-evaluated specimens were definitively identified as a new sand fly species, Pintomyia (Pifanomyia) veintemillasi, closely related to Pi. (Pif.) nevesi and Pintomyia (Pifanomyia) maranonensis within the Evansi series. This new sand fly was the third most numerous anthropophilic species at the floor (6.2%) and the second most numerous anthropophilic at the canopy (35.1%).
A new anthropophilic sand fly species is described as Pi. (Pif.) veintemillasi n. sp. This sand fly species was caught at about 900 m altitude in the Marimonos mountain range, a highly endemic area for cutaneous and mucosal leishmaniasis due to Leishmania (Viannia) braziliensis. Therefore, this species could be involved in the leishmaniasis transmission in the sub-Andean foothills of Alto Beni, Department of La Paz, Bolivia.
大多数沙蝇物种分布在美洲；有些是利什曼病和其他人类疾病的媒介。在玻利维亚，已鉴定出约 25%的新热带物种，其中只有少数几种被认为是皮肤和内脏利什曼病的媒介。本文描述了一种来自 Alto Beni 亚区的新的嗜人沙蝇物种。
在位于玻利维亚拉巴斯省 Sud Yungas 省 Palos Blancos 市的 Marimonos 山脉，海拔约 900 米的亚热带湿润森林中，进行了一次大型系统昆虫学调查。1982 年 1 月至 1984 年 2 月期间，在地面和树冠层使用 CDC 诱捕器和受保护的人类诱饵捕获了 24730 只沙蝇。在地面上共收集到 16 种 24730 只沙蝇，在树冠上收集到 3259 只，其中 8 种。其中一种被标记为 Pintomia (Pifanomyia) nevesi，但某些形态特征使我们怀疑它是那个分类群。为了确定这种沙蝇的身份，最近通过对可用于 mounted on Euparal 的标本进行形态分析和测量，对其进行了重新评估（本工作），这些标本之前被标记为 Pi. (Pif.) nevesi。
基于形态特征和测量值，重新评估的标本被明确鉴定为一种新的沙蝇物种，即 Pintomyia (Pifanomyia) veintemillasi，它与 Pi. (Pif.) nevesi 和 Pintomyia (Pifanomyia) maranonensis 密切相关，属于 Evansi 系列。这种新的沙蝇是在地面上第三多的嗜人种类（6.2%），也是在树冠上第二多的嗜人种类（35.1%）。
本文描述了一种新的嗜人沙蝇物种，即 Pi. (Pif.) veintemillasi n. sp.。该沙蝇物种在海拔约 900 米的 Marimonos 山脉中被捕获，该地区是由于 Leishmania (Viannia) braziliensis 导致的皮肤和黏膜利什曼病的高度地方性地区。因此，该物种可能参与玻利维亚拉巴斯省 Alto Beni 亚区的利什曼病传播。
