Genus Kaliofenusa


The genus Kaliofenusa have sometimes been considered as a sub-geuns of Fenusa. There are three species in Europe. In Britain the Kaliofenusa are represented by two species and in Ireland by one species (Kaliofenusa ulmi), though the systematics are uncertain and other species may be present.

The genus Kaliofenusa can be characterised within the Fenusini by the following features. The antennae are eight or nine segmented with the third segment longer than the fourth and the pedicel about as long as it is broad. The malar gap is less than the diameter of the front ocellus. The post-genal carina and the prepectus are both absent. In the forewing, the anal cell is complete with a small basal portion. Vein 2r joins RS before 3rm. The hind wing venation is simple with no enclosed cells. On the hind legs, the fourth tarsomere is strongly, apically produced beneath the fifth. The tarsal claws are simple. On the fore and middle legs, the tarsi are similar in length to their corresponding tibiae.

Larvae feed inside blister mines in the leaves of members of the Ulmaceae family.
