Notes on and synonymies of some European sawflies (Hymenoptera: Symphyta) By L. ZOMBORI (Received December 1, 1979) Abstract: Author established two synonyms, a new combination, gave a new name to a homonymy and records a species new for the Hungarian fauna. A key is given to the three European species of the genus Cladardis Bens. Heterarthrus ochropoda (Klug, 1814) Phyllotoma maxima Stróbl, 1896 syn. n. In dealing with some Heterarthrus problems I requested the type of Phyllotoma maxima Stróbl, 1896, which was kindly sent to me by Dr. habil. G. MORGE of j Eberswalde (GDR). Labels: the first pin with only a label on bears the inscription "maxima m Seiten­stetten Stróbl" (red label); the second pin carrying the female specimen has a label with "Ph. maxima m. Seitenstetten o_" on this label underneath reads "Phyllotoma/Aceris Kaltenb" (white label). The words underneath the label is referred to in the original description as a result of an identification by KONOW. ENSLIN (1914) when discussing the species belonging in this genus made a tentative synonymy under "Ph. leucomela Kl. o_ (maxima Stróbl ? )". Though he had an idea of a close relationship with ochropoda also, for he compared it to this latter species, too. I added to the pin bearing the specimen the following two labels: "Holotypus <j> Phyl­lotoma maxima Stróbl, 1896 teste Zombori 1980" and "Heterarthrus ochropoda Kl. ^ det. Zombori 1980". Cladardis semicincta (Hartig, 1837) comb.n. BENSON (1954) upon describing a new Monophadnus species made a short reference to this species: "M. semicinctus Hartig is so different from any of the species already men­tioned that it may perhaps represent a different generic group ..." (p. 281). Peculiarly e­nough, when he erected his genus of Cladardis Benson, 1952 he made it monotypic, basing it on Tenthredo elongatula Klug, 1814. When a few years ago I identified a Hungarian .jecimen of the species of M. semi­ cinctus Htg. I already had an idea about the close relationship of the two taxa. In a recent paper of mine (ZOMBORI 1977) I suggested this affinity. Through the kindness of Dr. Erioh H. DILLER of Munich (GFR), I had the opportu­nity to study the female lectotype and the male paralectotype of Tenthredo semicincta Hartig, 1837.
