Zombori, L.: New sawfly species in the Hungarian fauna (Hymenoptera, Symphyta), II

ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 68. Budapest 1976. New Sawfly Species in the Hungarian Fauna (Hymenoptera, Symphyta), II. by L. ZOMBORI, Budapest Abstract — Twelve sawfly species new to the Hungarian fauna are discussed in short. One species new to science, Pseudodineura mocsaryi Sp. n. originating from a faunal district of the Carpathian Basin is described. With 3 figures. Since the elaboration of the sawfly fauna of the Carpathian Basin has started new Species continuously come to light that had not been reported from this geographical region before. Such a list of sawflies was published recently in this journal (ZOMBORI 1975). Out of the 12 species briefly discussed hereunder, six belong to the subfamily Selandriinae, three to Blennocampinae and three to Nematinae. One species new to science belonging also to the subfamily Nematinae originates from a faunal district of the Carpathian Basin; it is described below. For the abbreviations used in this paper and for a longer list of pertaining literature please confer the previous paper (ZOMBORI 1975). 1. •Heterarthrus leucomelus (KLTJG, 1814)—- The representatives of the genus Heterart fonts are rather scarcely collected as adults

. Much easier to find the mines with larvae in the leaves of various arborescent plants. Apparently the fully developed individuals are on the wing for only a short time, though some species may have two generations in a year. A female specimen of H. leucomelus was collected by MIHÁLYI and ZSIRKÓ in the Bükk Mts., Nagyvisnyó, Elza-lak (1956. V. 28.-VI. 4.). According to the literature the larvae mine in the leaves of Acer pseudoplatanus

. Since ENSLIN I remember having seen this Species of great rarity listed in the literature only once (LORENZ & KRAUS 1957). ENSLIN said that the species was known in a few exemplars only and exclusively from Germany. Recently I identified another female specimen of this species for the Museum für Naturkunde der Humboldt-Universität zu Berlin sent to me by DR. E. KÖNIGSMANN, so I had the opportunity to compare the two specimens which were identical as far as specific features were concerned. This species obviously differs from H. ochropoda KL., primarily in its much greater size and also by the coloration of the body. (HNHM), 2. Heterarthrus microcephalus (KLUG, 1814) — Like the other representatives of this genus this conspicuously coloured species is also rare in our country. MOCSÁRY in 1897 included it in his well-known list of sawflies asj"Phull'otoma microcephala Klg. — Exemplar unicum e Zombor (Com. Bács)." Today Zombor belongs to Yugoslavia known as Sombor. The new Hungarian localities are: "Csepel, 1897, PÁVEL" (1 9); "Gyón, 1898. IX. 13, KERTÉSZ" (1 çf); "M. Besnvő, 1930. V. 4, A. GAMMEL" (1 çf); "Mecsek hegvs., Mánfa, 1955. V. 11, leg. MÓCZÁR" (1 $ ); "Fenyőfő, Kisszépalma környéke, 1965. V. 25,31., leg. PAPP" (1 9). (HNHM, BTMZ). 3. Strongylogaster lineata (CHRIST, 1791) — The two Central European Strongylogaster species are both feeding on Pteridium aquilinum and Polystichum filix-mas. S. xanthocera STEPH. was recently recorded from Hungary (ZOMBORI 1975). The above species was reported by MOCSÁRY in 1897 as "S. multifasciatus FOURCR. (cingidatus FABR.)" from localities which today are extra-Hungarian territories : " Pozsony, Montes Rabaszkala et Vihorlat (Com. Zemplén), Mehádia, Zágráb, Zengg". The new Hungarian localities are: "Zemplén — H. huta, 1st vánkút, 1955. VI. 6.-12., KASZAB—

SZÉKESS Y" (5 9); "Mecsek hegvs., Melegmány, 1955. VI. 7, leg. MÓCZÁR L." (1 9); "Kőszegi-hg., Kerdi-h., erdő, 1960. VII. 8, leg. ZSIRKÓ" (19); "Pankász, Vas rn., 1967. VI. 7, leg. MÓCZÁR" (1 9 )• — E x t r a-H ungarian localities belonging to the faunal districts of the Carpathian Basin: "Ravna Gora, Slavonia, Coll. Z. Kiss. E." (19); "M. Codru, Bihar, m., 1925, VI. 26, Coll. Z. KISS E." (19); "Retyezát, 1927, VII. 28." (1 $.). —• The list shows that all the specimens are females, which is not surprising if we know that the males of this species, contrary to those of S. xanthocera, are extremely rare. Some authors hold the view that the species reproduces mostly by parthenogenesis. (HNHM). Ann. Hist.-nat. Mus. Nat. Hung., 1976, 68. 14 Természettudományi Múzeum Évkönyve 1976 .
