背景:大多数沙蝇物种位于美洲;有些是利什曼病和其他人类疾病的媒介。在玻利维亚,大约25%的新热带物种已经被确认,只有少数人被认为是皮肤和内脏利什曼病的媒介。本文描述了来自AltoBeni亚安第斯地区的一种新的嗜人沙蝇。
方法:在位于Marimonos山脉的亚热带湿润森林中进行了大规模的系统昆虫学调查,在大约900米的高度,在PalosBlancos市,南云加斯省,拉巴斯部,玻利维亚。在1982年1月至1984年2月之间的26个月内,在地面和树冠层捕获了沙蝇,使用CDC的光陷阱和受保护的人类诱饵。在地面上共收集到24730只沙蝇,分布在16种,和3259在天篷里,8种。这些物种之一被标记为Pintomia(Pifanomyia)nevesi,尽管某些形态特征让我们怀疑它是那个分类单元。为了定义这只沙蝇的身份,最近通过形态学分析和安装在Euparal上的可用标本的测量进行了重新评估(这项工作),以前标记为Pi。(皮夫。)Nevesi。
结果:基于形态性状和测量,重新评估的标本被确定为新的沙蝇物种,Pintomyia(Pifanomyia)veintemillasi,与Pi密切相关。(皮夫。)Evansi系列中的nevesi和Pintomyia(Pifanomyia)maranonensis。这种新的沙蝇是地板上数量第三多的嗜人物种(6.2%),是树冠上数量第二多的嗜人物种(35.1%)。
结论:一种新的嗜人为沙蝇物种被描述为Pi。(皮夫。)veintemillasin.sp。这种沙蝇物种在Marimonos山脉约900米的高度被捕获,由于利什曼原虫(Viannia)巴西,皮肤和粘膜利什曼病的高度流行区。因此,该物种可能参与了利什曼病在安第斯亚山麓的AltoBeni传播,拉巴斯部,玻利维亚。
BACKGROUND: 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.
METHODS: 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.
RESULTS: 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%).
CONCLUSIONS: 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.
