For this female specimen I further added: "Lectotypus ^ Tenthredo semicinctus Hartig, 1837 des. Zombori 1979" and "Cladardis semicincta Htg. £ det.

Hartig"; "122" (blue label) ; "semicincta" (an ornamented label above and below the hand-writing); "Monophadnus semi­cincta Htg. ó* E. Clément det.". For this male specimen I further added:"Paralectotypus 6 Tenthredo semicincta Hartig, 1837 des. Zombori 1979" and "Cladardis semicincta Htg. ó* det. Zombori 1979". A close study of the type-specimens showed that the lack of a distinct postgenal ca­rina already excludes the taxon from the genus Monophadnu s Hartig, 1937. Furthermore, the slender body, the upturned apex of A3 in the fore wing readily directs us to the genus Clad­ardis Benson, 1952. Thus, the genus Cladardis today includes three European species, which may be separated as follows. European species of Cladardi s 1 (2) Head in dorsal view hemispherical, behind eyes much contracted. Clypeus shallow­ly emarginate over entire front margin. Apex of femur, entire tibia, at least basi­tarsus, greater part of tegulayellowish white. Abdomen brownish black, cercus yel­low. 5-6 mm , . . ,_, . ,_ _ semicincta (Hartig, 1837). comb. n. 2 (1) Head normal, not inflated or hemispherical, behind eyes parallel, weakly expanded. Clypeus truncate or more or less triangularly excised. Legs and tegula black. Ab­domen, including cercus black. 3 (4) Head with dense alutaceous surface sculpture and small punctures. Clypeus truncate. Outer orbit at upper corner of eye with a wide groove extending downward to about 1/3 of entire length. Thorax similarly sculptured as head. Front tibia in front dirty brown. Abdominal tergites 2-4 densely striated, 5-9 weakly alutaceous, sternites also. 8 mm , _•-,„„ . • ,„r,„ bordonn Zombori, 1976 4 (3) Head with only small punctures, no alutaceous surface sculpture present. Clypeus various in shape, frequently deeply, triangularly excised, or only weakly emarginate, never truncate. Outer orbit smooth, without a groove. Front tibia in front dirty white. Abdominal tergites 2-4 shining with very weak (sometimes absent) alutaceous surface sculpture, 5-9 rather mat. 5-8 mm . . , r elongatula (Klug, 1814) Hinatara nigripes (Konow, 1907) The rather short flight period of most mining sawflies much hampers the collecting of the imagoes. In many a collection only a few specimens are found. Those who take the trouble of collecting larvae still in mines stand a better chance in obtaining a longer series of reared imagoes. Owing to meagre materials, there is much confusion in interpreting one or the other species, thus, in most cases the examination of types becomes inevitable. Hinatara nigripes Knw. a tiny, black species with scarcely any reliable distinguishing fea­tures in the description presented the same problem. I collected some thirty nearly fully fed larvae still in mines of Acer campestre at Nagykovácsi (near Budapest) on the 20th of May, 1978. In the following year 11 p and 4 S emerged: the males on the 14th and 15th of April (two on each day), while the females from the 15th to the 27th of the same month. I was almost certain that these specimens were H. recta (C.G. Thomson, 1871) this time reared from a different host plant since the latter species was supposed to feed in the leaves of Acer platanoides, an observation by R. MALAISE in Stockholm. I was further in­clined to accept this notion for BENSON (1941) suggested that nigripes "is possibly synony­mous" with recta . On the other hand, I had some doubt, because KONOW (1907) mentioned a rather obvious feature in his description of nigripes "fronte superiore super antennas et sub ocello inferiore foveatim impressa", which my specimens clearly displayed.
