BACKGROUND
Phlebotomine sandflies are the vectors of etiological agents of leishmaniases in several areas of the world. In the Neotropical Region, the biodiversity of these insects is more than other regions, probably due the long evolutionary period of this group. Miocene amber from Dominican Republic, currently, has a record of 14 extinct species of Phlebotomine sandflies.
RESULTS
This paper describes a new fossil species of phlebotomine sandfly from amber found in Dominican Republic. This new species is based on morphological characters of a male such as 5 degrees palpomere longer than 3 degrees + 4 degrees , three well-developed spines in the gonostyle, lateral lobe longer than gonocoxite and permit inclusion of the new species in the genus Pintomyia, series serrana. The paramere, with a curvature in the ventral margin, of the middle of the structure, separates the new species from the others fossils or extant species.
CONCLUSION
The new species described in the present study named Pintomyia dissimilis nov. sp. is well differenciated from all known species in this genus.
背景
白蛉是世界上多个地区利什曼病病原体的传播媒介。在新热带地区，这些昆虫的生物多样性比其他地区更为丰富，这可能归因于该类群漫长的进化时期。目前，来自多米尼加共和国的中新世琥珀中有14种已灭绝的白蛉物种记录。
结果
本文描述了一种在多米尼加共和国发现的琥珀中的新化石白蛉物种。这个新物种基于雄性的形态特征，如第5节触角节比第3节+第4节长，生殖突上有三根发育良好的刺，侧叶比生殖基节长，并允许将该新物种归入Pintomyia属，serrana系列。在结构中部，腹缘有弯曲的阳茎侧叶，使该新物种与其他化石或现存物种区分开来。
结论
本研究中描述的新物种Pintomyia dissimilis nov. sp.与该属所有已知物种有明显区别。
