Euura godmani - Godman's Willow Nematine

The identity of Scottish specimens requires further study as they are not a good match for specimens identified as this species in Switzerland (the location of the type specimen).

This species is similar to the circum-polar species Euura variator (not in Britain). Males and females occur in equal number. The colour is dark with yellowish to off-white on the labrum, clypeus, madible bases, genae, around the eye orbits and the pronotal angles. On the legs the bases of the coxae, trochanters, apices of the femora, more or less the tibiae and the bases of the tarsi are also pale. On the abdomen, the lateral faces, sternites and the apical tergite are similarly pale. Males have longer antennae than the females but are similarly coloured and can be determined by the shape of the penis valves.

Larvae thought to feed on creeping willow.

Size: Female: 6.0 - 8.5mm, male: 5.5 - 7.5mm
