Authors: Guglielmino, Adalgisa; Bückle, Christoph; Remane, Reinhard Abstract: The results of several research trips carried out during the past six years in the Central Italian regions of Lazio and Abruzzo (including only few localities in Umbria), covering a variety of biotopes from coastal up to high mountain sites, are presented: 331 species were found, 3 of them - already published separately - new to science (Kelisia italica Guglielmino & Remane, Rhopalopyx cigigas Guglielmino and Euscelis venitala Remane, Bűckle & Guglielmino), 10 of them apparently not yet recorded from Italy, 11 probably first records from continental Italy, even more (38) seem to be first records for "peninsular" Italy ("S" of D'Urso, 1995). These numbers demonstrate the gaps in previous research as well as the need for further research in order to obtain a reliable basis to recognize the change of species distribution or even species set in future times (results e.g. of global warming, pollution etc.). For all species their distribution - altitude, biotopes etc. - in the examined region is discussed, for some of them in comparison with their geographic distribution in Italy, for some taxa taxonomical or nomenclatural remarks are added. An appendix mentions some taxa (3 of them new for peninsular Italy) collected 1977 in Marche/Umbria (Monti Sibillini) and Abruzzo by the third author. 2004-12-31T23:00:00Z http://hdl.handle.net/2067/1760 Title: Insecta Hemiptera collected in the Mont Avic Natural Park (Aosta Valley, Northwest Italy).

Altogether 126 species of Heteroptera, belonging to 89 genera, 108 species of Auchenorrhyncha, belonging to 75 genera, and 30 species of Sternorrhyncha Psyllomorpha, belonging to 8 genera were collected at the four different elevation sites of Capoluogo-Tendeur (500-600m a.s.l.), Chevrère (1200-1400m a.s.l.), Dondena (2100-2300m a.s.l.), and Miserin (2588m a.s.l.). Of these species, 2 were new records for Italy: the Mirid Lygus maritimus and Cicadellid Edwardsiana ishidai. New records for Italy are also the Pipunculid Dipteran Tomosvarjella freidbergi and the Halictophagid Strepsipteran Halictophagus languedoci, parasitoids of Auchenorrhyncha. 2008-12-31T23:00:00Z http://hdl.handle.net/2067/1568 Title: Euscelis venitala nov. sp., a new Euscelis taxon from the Appennine Mountains of Central Italy. Authors: Remane, Reinhard; Bückle, Christoph; Guglielmino, Adalgisa Abstract: Euscelis venitala n. sp., a new Euscelis taxon from the Appennine Mountains of Central Italy. E. venitala n. sp. is rather similar and probably most closely related to E. venosus (Kbm.), but clearly differs in structures of the male (“Dorsalrand-Struktur”, edeagus) and female (base of G VIII, “Intervalvenstück”) genitalia. Living on meadows it is so far known from 4 localities situated between 1000 and 1400m elevation in the Central Appennine Mountains (Monti della Laga, Maiella), i.e. allopatrically distributed with E. venosus (Kbm.) inhabiting a large “montaneous” area from northern Spain and Great Britain into Russia (recorded as far east as Kazakhstan and Altai Mts.), but in Italy apparently confined to the Alps. As structural differences between both taxa are distinct and no “transitional” variation was found in each taxon, we take these differences as a proof for interrupted gene flow due to a low “spread ability” of both taxa (all specimens - 130 - of E. venitala n. sp. seen so far are brachypterous, and so are most of E. venosus (Kbm.)). Until contrary evidence is brought up we consider E. venitala n. sp. as endemic species of the Central Region of the Appennine Mountains - a region rich in endemic taxa also in other groups of animals. 2004-12-31T23:00:00Z http://hdl.handle.net/2067/1532 Title: An additional taxon of the Kelisia guttula group from Central Italy: Kelisia italica (Auchenorrhyncha, Fulgoromorpha, Delphacidae). Authors: Guglielmino, Adalgisa; Remane, Reinhard Abstract: Kelisia italica n. sp. found in high altitudes, between 1800-2200 m, in two mountain regions of the Central Italy (Monte Terminillo, Monte Velino) is described. It is closely related to K. guttula (Germar) sensu Wagner and K. sima Ribaut, but is easily distinguished from these species by the shape of the male genital segment (lobuliform projection of the caudal margin lateral of the anal tube) and the lack of the aedeagal lamella. In addition, it differs from K. vittipennis J. Sahlberg by the bigger spot on the genae, the lack of dark markings on the pronotum between eyes and scutum, and by the shape of the aedeagus, and from K. irregulata Haupt by its smaller size, the bigger spot on the genae and the male genital morphology. In the female genitalia there exists a very broad basal part of the “edeagal duct” not present in any other species of the K. guttula-group. 2001-12-31T23:00:00Z http://hdl.handle.net/2067/1531 Title: Description of Platymetopius melongicornis, new species of P. undatus-group, with some remarks on taxonomic questions in west-palaearctic Platymetopius Burmeister, 1838 (Auchenorrhyncha, Cicadellidae). Authors: Remane, Reinhard; Guglielmino, Adalgisa Abstract: Platymetopius melongicornis n. sp. is described from several countries of southern Europe (Spain, Portugal, France, Italy, Greece, type locality: Villefranche-sur mèr in France, Dépt. Alpes Maritimes). It is distinguishable from the very similar P. major (Kbm.) by the structure of the male genitalia (aedeagus with a pair of very long but simple apical appendages and a pair of rather short and thin basal appendages, shape and proportions of the pygofer appendages, shape of the styli). Its area of distribution overlaps largely with that of several other taxa of this group, including P. major (Kbm). 2001-12-31T23:00:00Z http://hdl.handle.net/2067/1566 Title: Female ectodermal genitalia of the taxa of the Kelisia guttula-group (Homoptera Fulgoromorpha Delphacidae): not only an example for specialized coorganization with male genitalia without obvious reasons, but also a character set apt for species discrimination in westpalaearctic taxa? Authors: Remane, Reinhard; Guglielmino, Adalgisa Abstract: In the course of evolution male and female external and internal ectodermal genitalic structures in the taxa of the monophyletic Kelisia guttula-group have been enlarged and differentiated in a very special way in comparison to plesiomorphic taxa of Kelisiinae. Functional reasons for this “orthogenetic” evolution are not yet known, as it seems. In evolutory “coorganization” the evolution of a proportionally very large genital segment and an extremely long, thin and flexible aedeagus in the males is “answered” (for there seem to be - other than in some other insect taxa, e. i. Diptera Tephritidae - no special “female” functions like oviposition or “sperm handling” which may act as “selective forces” on these structures, by this changing their morphology) by the females with the development of a special duct of approximately “edeagal length” guiding and keeping the male aedeagus during copulation. This “edeagal duct”, which morphologically is “folded off” from the genital room, starts at the dorsal base of the female’s genital room and ends opposite the depart of the oviductus communis (leading to the spermatheca as well as to the ovaries). It is much longer than the genital room, but it remains connected with it by a thin ligament. It is provided with a variety of sclerotized structures. This could be interpreted as a “lock and key” mechanism to prevent successful mating between specimens belonging to different species, but such matings are prohibited already by species-specific vibratory signals acting as “premating isolating mechanism”. As in the K. guttula-group there exist several species-groups containing externally very similar species, in which the females could not be identified down to species up to now (resulting in “handicaps” for biogeographical and ecological analyses), we examined these structures looking for species-specific characters enabling the safe identification not only of males, but of females, too. As a result all females of this group now may be safely identified due to such species-specific characters present in their internal ectodermal genitalia. The populations of “Kelisia irregulata Haupt” from Spain and western France have shown to be that different from the allopatrically distributed central european populations, that they seem to be a genpool of their own. So we decided to describe these populations as a species of its own: Kelisia occirrega n. sp. (Type locality: Spain, Prov. Pamplona, Isaba in the Valle del Roncal in the southwestern Pyrenees). This taxon ought to keep its species rank unless intermediate, transitional specimens will be discovered in the “gap” between the two taxa (situated in eastern France) indicating the existence of a “hybrid belt”. 2001-12-31T23:00:00Z
