Abstract

A trypanosomatid (Trypanosomatidae: Kinetoplastida) associated with a blood-filled female sand fly in Cretaceous Burmese amber, is described in the new genus and species, Paleoleishmania proterus. The genus Paleoleishmania is established as a collective genus for digenetic fossil trypanosomes associated with sand flies. Amastigotes, promastigotes and paramastigotes are described. Paleoleishmania proterus is the first fossil kinetoplastid and provides a minimum age for the digenetic Trypanosomatidae. Its discovery indicates that vector-borne pathogens had been established by the Early Cretaceous.

摘要

在新属新种古利什曼原虫（Paleoleishmania proterus）中，描述了一种与白垩纪缅甸琥珀中一只充满血液的雌性沙蝇相关的锥虫（锥虫科：动基体目）。古利什曼原虫属被确立为与沙蝇相关的双源化石锥虫的集合属。文中描述了无鞭毛体、前鞭毛体和副鞭毛体。古利什曼原虫是首个化石动基体目生物，为双源锥虫科提供了最小年龄。它的发现表明，媒介传播的病原体在早白垩世就已存在。
