P.S. Laquelle dit de F. ulmi :
Occasioned by the work of Altenhofer (1980a,b,c) it was discovered by Liston (1993b) that, what had been considered up to then as F. ulmi actually consisted of three species. Liston’s study was limited to the adults, and no other differentiating characters were published than that each was living on one elm species : ulmi on Ulmus glabra, carpinifoliae on U. minor, and altenhoferi on U. laevis ; a few years later it became clear that F. carpinifoliae was to be sunk in synonymy of altenhoferi.
Fenusa altenhoferi (Liston, 1993) ne serait connue que d'Allemagne mais si je comprends bien, on connaît mal tout ça.Fenusa ulmi = Kaliofenusa ulmi (Serville, 1823) is an insufficently known species ; it may well be the valid name of F. ulmi or F. altenhoferi, but as long as the type has not been studied, if it exists at all, this cannot be decided and the the name is to be disregarded. That applies as well to references to this “species” like in Savina & Chevin.
Donc ok.
