E-mail: [email protected] Contribution to the knowledge of the Chamaemyiidae (Diptera) of Italy, Switzerland and some Mediterranean countries with the descrip- tion ofParochthiphila {Euestelia) ephesi n. spec, from Turkey. -A new species, Parochthiphila {Euestelia) ephesi sp. n. from Turkey is described, illustratedand comparedwithrelated species. There follows a list of19 spe- cies ofthe genera Parochthiphila, Chamaemyia and Leucopis, collected in Italy, Switzerland and several countries around the Mediterranean. Parochthiphila {Euestelia) nigrolineata Beschovski & Merz is recorded for the first time from Italy (Valley ofAosta), Parochthiphila {Parochthiphila) inconstans (Becker), Parochthiphila {Euestelia) nigripes (Strobl), Chamaemyiajuncorum (Fallèn) and Chamaemyiapolystigma (Meigen) are new for Cyprus, and Parochthiphila {Euestelia)frontella Rondani is new for France (Corsica) and reported for the first time from the following Italianregions: Sardinia, Lazio, Puglia. The frequentlymisidentified species Chamaemyia aridella (Fallén) is illustrated to show the variability in the shape ofthe aedeagus. Keywords: Diptera - Chamaemyiidae - new species - Parochthiphilia - Chamaemyia - Leucopis. INTRODUCTION The Chamaemyiidae, with larvae that prey on Aphidoidea and/or Coccoidea, mm are small, generally silvery grey flies (1-5 long) found in all zoogeographic areas, although the majority of known species are described from the Palaeartic Region. Faunistic and systematic knowledge ofthe family in the Palaearctic Region, however, is still fragmentary and rather poor, partly due to difficulties in collection and species detemiination, in particular with regard to females. Worldwide, this family comprises more than 250 described species, divided into 27 genera and subgenera. The family exhibits characteristic trophic specialization at generic or subgeneric level (McAlpine, 1960, 1971; Raspi, 1983a, 1983b, 1985, 1988, 1995, 1996, 2003, 2005, 2006, 2008; & & & Raspi Bertolini, 1993; Gaimari Raspi, 2002; Raspi Ebejer, 2008; Tanasijtshuk, 1986, 1996, 1997). Manuscript accepted04.10.2012 14 A. RASPI Thiscontributionpresentsthe dataandspecies determinations ofnumerous spe- cimens ofDiptera Chamaemyiidae, collected in Switzerland and some Mediterranean countries, mainly in Italy. MATERIALAND METHODS This study is based on 287 specimens collected with an insect net in the follo- wingcountries: Italy, Switzerland, France, Malta, Cyprus andTurkey. Inpreparationof the genitalia, the final segments ofspecimens were removed and soaked in ahot KOH solution for several minutes, rinsed in distilled water, studied and stored in a drop of watersoluble Faure liquidonthe labelunderthe specimen. Morphologicalterms inthe descriptions follow McAlpine (1981, 1987). Two asterisks ** signify that the species is new for this country (Gaimari & Tanasijtshuk, 2011) and one asterisk * after an Italian region indicates thatthe species is here forthe first time recorded inthis region (Raspi, 1995). In general, at least one specimen ofeach species is deposited in the Muséum d’Histoire Naturelle de Genève (MHNG). Duplicate specimens are retained in the Dipterological Collectionofthe “G. Scaramuzzi” DepartmentofColtivazione e Difesa delle Specie Legnose, Pisa University (CDSL). RESULTS Parochthiphila {Euestelia) ephesinew species Figs 1-7 Holotype: d, W.

Remarks: The new species can be assigned to the P. (E.) coronata (Loew) group on the basis ofits 1+3 strong dorsocentral setae. Within this group only P. (E.) kimmerica Tanasijtshuk, 1968, withdarktibiae, andalsoknown fromTurkey (Raspi & Ebejer, 2008), is similar to the new species, but they differ in the colouration ofbody (gilded brown sheen in the new species) and in the brown orblack frontal band that is presentonly inthe female inP ephesi sp. n. butinboth sexes inE. kimmerica. Further, they differ in the structure ofthe male genitalia. Biology: Unknown. Judgingfromitsgenericpositionitmaybespeculatedthat the larvae may be found between the leafsheaths and secondary stalks ofGramineae infested by Pseudococcidae (Stemorrhyncha), where they prey on mealybugs as other species ofParochthiphila and Chamaemyia with knownbiology (Raspi, 1983a, 2006).
