Sl-lüOl Ljubljana, SJovcnia L-mail; bogdanlmrvalOlfSyahco.coin Jntroiiuciion Superfamily Empidoidea is divided inio Empididae (s.str.), Hybotidae, Atclesiidae, Microphoriüaeaiid Dolithopodidae. The most impomni study on the adiill Ejiipididae morphology has been published by ChvAla (1983) which is priniarly based on Palaearctic material. The family Enipididae includes subfamilies Oreogetoiifnac, Empidinae, Urachystomalinae, Ceratomerinae. Clinoceritiae and Hcnicrodromiinac. The genus Chelifera of the subfamily Henierodromiirae was founded by Macquart (iR23) for the type species Chelifeni raptor matguari i^Chelifertj monostigmci (MnrccN, 1822) thai occurs in Europe (ChvAla & Wagner, 1989). Five imptirüml revisümtil papers dealing wiih Chelifera, including morphology and taxonomy of tke species, had previously been published: Mr lander's (192R, 1947) reviews of tlie Ncarctic species. Coll im's (S 927, 1961) works on (he Britisli speeies, and Mac Donald's (1994) revision in which 21 Nearetic and I 1 lolarttic species were recognized and illustrated, six of ihem were described from North Amcrica as new to science. Generic description of Chelifera which belongs to tribus I lemerodromiini was in general best made by Collin (1961). Plienoh^v und fife cycle. The adults of Cfteiifera may be inainly found near mnning waters on the riparian vegetation and stones, or around Ihe spring areas on the herbage and under fallen leaves and branclilets, but usually in low numbers. Both feeding and mating activity when the males are giving ''a gift", usually a small eapturcd fly to the females, are taking turn on the ground, very often in the same time. They prey on Chirononiidae, Mycetophilidae and other small insccts. Some species which occur in the temperate and warm climates may have two generations per year {bivoltine species}, but usually ihey are utiivoliine. They arc common in dry summer season. All Hemerodromlinae have four larval in stars, and a pupa! &tage. Eggs are elongate and whitish, Larvae of CheUjera are also predators. They are Jiving in sand under stones deeply in flowing water or in spring areas among mosses where they prey on chironomid and si mul i id larvae. Body is cylindrical, vorm-like, only 2-5 mm long, almost whitish in colour, with seven pairs of abdomitial pixjfegs. Abdominal terniirial segment is posterioi ly rounded, bearing two small dorsal and one apical tubcrcules each covered by two pairs of long hair-like bristles. Pupae possess long spiracutar process laterally on each side, altogether one pair of prothoracic and seven pairs of abdominal processes, Pupa or adult escapes from the last iarv al skin through a T-shaped opening in the back. Morphology. Chelifera are small Hies with mantoid habits which arc characterized by die lengtlietied raptorial fore legs and are therefore highly adapted for predatory activity. Body length including tenninalia is between 2.0 and 6,5 mm. The females are usually bigger than males. The species whieh occur m New Zealand are distinctly smaller in comparison with "continental" species, and with shorter wings. Also in the mountain species and those which occur in the islands, the wings are usually shorter than body. The morphological study showed wide variation in the features important in species identification, which are principally the presence of thoracic longitudinal stripes and wing stigma, a degree of reduction of wing venation, moditleations of front femora (blackish or brownish patches) and middle legs chaetotaxy (additional sensory bristles and thom-Iike spines) in males (middle ^egs in females are not modified), reduction of male abdominal tergum 8 (exception arc three btisal Nearctic species), and the shape and degree of sclerotization of female terminalia, Chaetotaxy of thorax and legs is in general greatly reduced. Colouration of different body parts (e.g. head, antennal style, humeral depression, tarsal and abdominal segments) is a very useful feature to distinguish both males and females (Collik 1%1; Waon^k. 1997), It is commonly used in present TajKwuirtiical it^cs, ntid Jcscri|>[lLWi< ctf ÜK nfw Chiihfit-ii sp«iK < tJipljri -1 jmpwiidMl descriptions but sometimes it has no value neither in diffen^ntial diagnosis nor in pliylogenctic analysis of the species. Tlie male teniiinalia provide the most specific characters fordi-itingiiishing the species. Staie ofhjowleJge, Fauna of CheUfeni is best known from Palaearctic ami Ncarctic regions, Additional species were in the past described from New Zealand (Milli-r, 1923; Cou.in, 1928), and Chile (Cof-ljm, 1^33), The genus doesn't occur in Australia (Sl^CLA[|^, pers, com ). Several new species have been described in tite rccent past (Horvat, 1990 b; Lavali pi;:, 1975; Mac Donald, 1994; niesiolowski, 19S6; Vailuint, 1981, Vmlu^nt & ChvAla, 1973; Vaillant & gaü^eur, I99S; Yang DiNti & Yang Che-kun, 1995; waont:«, 1984 a, b; Waoner & NjtsioLowst;]. 1987), Altogether 60 species are recently rccognized from North America, Hurope, Asia, New Zealand, North Africa, and Chile (see A chcckl ist of the world species at the end of paper). Two spccies are Holarctic, 29 Palaearctic, 21 Nearctic, 3 Oriental, 4 Austral-Oceanian, and 1 Neotnipical. Three species remain unrecognized at present. Only a few spccies arc widely distributed in the Holarctic. On the other hand a half of all inciudcd spccics are known only from the type specimens (usually males) o rat the most from two or three localities, and no additional materia! is available. Many fiirther species will surely be discovered and described in the near future, predominantly from Asia and North America, Information on eight European species distribution treated here is mainly based on data from the Catalogue of Palaearctic Diptera (ChvAla & Waünf-:r, 19R9>as well as my published data (Hokvai, 1990 a, 1993, 1995 a, b, 1997). As regards the Southeast Europe, till 1990 a very few zoogeograpbical data were available in the literature. The ChcHfera adults are not commonly collected in the field, and they are rare in tlie collections around the world. The female can be usually recognized on tJie basis of the body colouration (e.g. the presence o (thoracic lateral stripes, wing stigma) of the corresponded male. Much more fresh Chelifera material collected in the field is needed in the future to solve taxonomy and phylogeny of the species.
