Pachynematus lichtwardti Konow, 1903
North to northern Scotland, fairly frequently recorded (Musgrove, 2024).
A broadly black insect with yellow-brown on the tip of the mandible, the labrum, the tegulae, more or less the apical tergite and the hypopygium. On the legs the coxae are black with brownish apices; the trochanters are more or less brown; the femora black with yellow-brown apices. Often the basal half of the legs is black, the tibiae are light yellow-brown darkened apically and on the tarsi. In males, the shape of the procidentia (anchor-shaped with a raised apical rim) and the penis valve are diagnostic.
Euura litchwardti larvae feed on grasses.
