Kaliofenusa altenhoferi Liston, 1993

Kaliofenusa altenhoferi

Males are rare. Colour and sawsheath appear to be unreliable for identification. In this species the frons has lateral walls that appear to be deeply indented and lateral foveae in short, deep, ellipsoid furrows that stop short of the frontal furrow.

Eggs are deposited in the leaf margin of field and English elm from where the larvae forms a blister mine that can eventually fill the entire leaf blade. The Kaliofenusa species appear to prefer suckers and regrowth.
