Dolerus gilvipes

Dolerus gilvipes will key to Dolerus pratorum in Benson's key as he considered it a subspecies. However, distribution studies have shown that Dolerus gilvipes is a separate species with a subarctic distribution. According to Morice, Dolerus gilvipes has an entirely black abdomen and the stigma of the forewing is paler at the base than the apex. The tibiae, pronotum and tegulae are marked with reddish yellow.

Larvae are unknown but probably feed on horsetails.
