NARTSHUK (*) THE CHLOROPIDAE OF THE NATURE RESERVES “AGORAIE DI SOPRA E MOGGETTO” (LIGURIA, GENOA) AND “GUADINE PRADACCIO” (EMILIA-ROMAGNA, PARMA) (Diptera) INTRODUCTION The Chloropidae are a family of Diptera Cyclorrhapha, sectio Acalypterae. The adults generally are small to very small flies (body length 1-4 mm), rare- ly reaching as much as 8 mm. The body is smooth with reduced chaetotaxy, colour usually black, grey, yellow or greenish with black stripes and marks. Chloropidae occur in all terrestrial ecosystems from tundra to tropical forest, savannas and deserts. They are abundant in grasslands, bogs, marshes, a few live in forests. Some species are very numerous in agricultural fields and are economic pests of cereals. The mode of life of the larvae is diverse. Most spe- cies, especially in temperate zones, are phytophagous, and develop in various parts and tissues of Poaceae, Cyperaceae, and other Liliatae (Canzoneri et al., 1995). Phytophagous larvae are usually common in more advanced groups. Some species are saprophytophagous, living in plants damaged by other in- sects. Larvae of some forest species live under bark of trees, in rotten wood, in damaged coniferous cones. Carnivorous species live in egg sacks of Araneae, egg-cases of Mantodea, egg pods of Orthoptera, or in the ground in rhizomes of plants, feeding on root aphids (Ismay & Nartshuk, 2000). About 3000 spe- cies are known worldwide (Canzoneri et al., 1995); 394 species live in Europe (Nartshuk, 2007) and 199 in mainland Italy (Canzoneri et al., 1995; Nartshuk, 2007). STUDY AREAS Two State Biogenetic Nature Reserves of the northern Apennines were in- vestigated: “Agoraie di Sopra e Moggetto” and “Guadine Pradaccio”.

E-mail: [email protected] 301 Reserves are situated near the border of Liguria and Emilia-Romagna re- gions. The Reserve “Agoraie di Sopra e Moggetto” is in the territory of the com- mune of Rezzoaglio (Genoa province, Liguria region) and includes, chiefly, forests of beech (Fagus sylvatica) and lacustrine habitats. The Reserve “Guadine Pradaccio” is in the territory of the commune of Cor- niglio (Parma province, Emilia-Romagna region) and in those of the National Park of the Tusco-Emilian Apennines. It is covered, prevalently, by beech- woods with peat bogs, and is characterized by the presence of two lakes. Further details on these Reserves are provided by Bonani & Olivari (2002), Cerretti et al. (2003) and Spada et al. (2009). MATERIALS AND METHODS The examined material was collected during the period 1999-2001 in the Reserve “Guadine Pradaccio” and during 2008 in the Reserve “Agoraie di So- pra e Moggetto” by the staff of the Centro Nazionale per lo Studio e la Conser- vazione della Biodiversità Forestale “Bosco Fontana” of Verona (cf. Cerretti et al., 2003; Spada et al., 2009). The material from the Reserve “Guadine Pra- daccio” was already object of a paper (Nartshuk, 2003); here are reported only the few specimens still undetermined. Most of specimens were collected with Malaise traps (cf. Cerretti et al., 2003; Spada et al., 2009). The species are listed according to the nomenclature and systematics of Nartshuk (2007). The following information is provided for each record: locality, altitude, date of collection, collector/s, method of collection, number of specimens and sex. A chorotype (sensu Vigna Taglianti et al., 1993, 1999) is reported for all species. Chorotypes were delineated on the basis of the distributions provided by Nartshuk (2007). The material is keep in the collection of the Centro Nazionale per lo Studio e la Conservazione della Biodiversità Forestale “Bosco Fontana” of Verona (Italy). ABBREVIATIONS Collecting sites.
