Syndiamesa edwardsi

Syndiamesa edwardsi (Pagast, 1947) Sympotthastia edwardsi Pagast, 1947: 459. Material examined. 2 pinned ♁♁, now mounted on the same slide, labelled: ‘ Synd. macronyx K. // Gastein 13. VII. 1907 // coll. Holdenberg // R.I.SC.N.B. 18.073 / Coll. et det. M. Goetghebuer’. Comments. Examination of the hypopygium indicates that both specimens belong to S. edwardsi, characterized by a tubercle-like expansion on the gonostylus. Syndiamesa macronyx Kieffer, 1918 from the type locality ‘ Italien Alpen, Mont Cenis’ (KIEFFER 1918), assigned to the genus Onychodiamesa Pagast, 1947 by PAGAST (1947) and currently treated as a valid species in Diamesa, clearly is a different species (see PAGAST 1947: Figs 17‒18). It is concluded that Goetghebuer’s identification of the RBINS specimen as ‘ Synd. macronyx ’ is incorrect.
