Remarks. Heer (1841) attributed Trichopteryx kunzei in his “Fauna Coleopterorum Helvetica” to Chevrier, who, however, never published this manuscript name. The type locality was cited as Genf (= Geneva). No syntypic material of this species could be traced in the collections of the Eidgenössische Technische Hochschule Zürich (M. Schmid, personal communication), where the Heer collection is preserved, nor in MHNG (G. Cuccodoro, personal communication). In the Chevrier collection, kept at WML, there are three unlabelled specimens standing as Ptilium kunzei . From Chevrier's catalogue that accompanies his collection it becomes clear that these should be treated as syntypes. The entry under “ Kunzei Mihi” reads: “G. HFH.”, where “G.” is used as shorthand for Geneva and “HFH.” most likely stands for Heer's Fauna Helvetica. The three specimens are conspecific and fit the current interpretation of Trichopteryx kunzei . A female specimen, whose identity could be confirmed by the apical fringe of the elytra, is herewith designated as lectotype.
