摘要： Helophilus nothobombus sp.十一月（双翅目：食虫科）是根据 Randeck Maar（德国西南部施瓦本阿尔布）的早中新世湖泊沉积物进行描述的，并与该属的其他化石物种进行了比较。 Helophilus primarius Germar, 1837 和 Helophilus villeneuvi Théobald, 1937 没有表现出诊断特征，无法归属于 Helophilus 属甚至 Eristalini 族。因此，Helophilus miocaenicus (Stackelberg, 1925) 和 H. nothobombus 是该属唯一可能的化石物种。 Helophilus 的鼠尾蛆很可能是 Randeck Maar 湖岸生物群落的一部分。层蝇科幼虫的出现频率表明，该地区也为嗜蝇属及相关属的物种提供了适宜的栖息地。
Abstract: Helophilus nothobombus sp. nov. (Diptera: Syrphidae) is described from Early Miocene lake sediments of the Randeck Maar (Swabian Alb, south‐west Germany) and compared to other fossil species of the genus. Helophilus primarius Germar, 1837 and Helophilus villeneuvi Théobald, 1937 do not show diagnostic features that allow assignment to the genus Helophilus or even to the tribe Eristalini. Helophilus miocaenicus (Stackelberg, 1925) and H. nothobombus thus are the only plausible fossil species of the genus. The rat‐tailed maggots of Helophilus most probably were part of the biocoenosis of the shores of the Randeck Maar lake. The frequency of larvae of Stratiomyidae shows that there were also suitable habitats for species of Helophilus and related genera.
