Xylomya ciscaucasica (Pleske 1928) and Xylomya mlokosiewiczi (Pleske 1925), previously only known from the Caucasus, are recorded from Turkey for the first time in this study. The male genitalia of X. ciscaucasica and the female genitalia of X. mlokosiewiczi and X. maculata (Meigen 1804) are illustrated for first time. The distribution of these species is briefly discussed and a key to Turkish species is given. Also a key to Turkish genera of Xylomyidae is given. Key Words: Xylomyidae, Xylomya, new records, distribution, Turkey RESUMEN Se informa y se ilustran las especies de Xylomya en Turquía en este trabajo. Anteriormente, sólo se conocian Xylomya ciscaucasica (Pleske 1928) y Xylomya mlokosiewiczi (Pleske 1925) en la región del Cáucaso, pero se registran las dos especies en Turquía por primera vez en este estudio. Se ilustran por primera vez los genitales del macho de X. ciscaucasica y los genitales las hembras de X. mlokosiewiczi y de X. maculata (Meigen 1804). Se discute la distribución de estas especies brevemente y se provee una clave de las especies de Xylomya en Turquía. También, se provee una clave de los géneros de Xylomyidae en Turquía. The family of Xylomyidae has 4 genera in the world: Arthropeina Lindner 1949, Coenomyiodes Brunetti 1920, Solva Walker 1859 and Xylomya Rondani 1861 (Woodley 2011). Adult xylomyids are generally found in wooded areas and tropical forest (Krivosheina 1976; Woodley 2011). This small family includes 33 species in Solva and 23 species in Xylomya in the Palaearctic Region (Kri- voshenia 1988, 1999a, 1999b; Woodley 2011). Only 2 species, Solva marginata (Meigen 1820) and Xylomya maculata (Meigen 1804), are known from Turkey (Üstüner & Kalyoncu 2005; Üstüner and Öztürk 2002). The specimens examined in the present work are deposited in the Zoological Museum of Gazi University (ZMGU). KEY TO GENERA OF XYLOMYIDAE FROM TURKEY 1.

Hasbenli leg (Figs. 1- 2 and 19). Mesonotum with indistinct yellow spots on transverse suture, scutellum yellow laterally and apically but black dorsally in basal half. Tibia lighter, black only at extreme apex. Abdomen black, with small rectangular yellow spots on tergite 2. Tergites 3-6 with pale posterior margins. This species has been previously recorded only from Vladikavkaz and Alagir in North Ossetia. It is recorded here for the first time from Turkey. Male Genitalia: Epandrium almost oval. Surstyli of epandrium rather slender and about 2/3 as long as epandrium as well as paraproct. Synsternite large and oval. Distisyles about 1/3 as long as height of synsternite and about as large as parameres. Aedeagus smooth, parameres large, sharp at apex and relatively longer than distisyles (Figs.7-11). Xylomya maculata (Meigen 1804) (Figs. 5, 6, 12, 13, 14, 15 and 19) Material Examined: Turkey: Antalya, Alanya, Gevne Village, elev. 1500 m, 17 VII 1999, 1 female, T. Üstüner leg (Figs. 5-6 and 19). Mesonotum with longitudinal yellow stripes interrupted at middle and connected to yellow humeral spots. Yellow pleural spot extending over upper mesopleura and on the part of pteropleura. Legs predominantly yellow, but all coxae black and apical third of hind femora and tibia and also last 3-4 tarsal segments black. Abdomen with narrow yellow stripes along posterior margins of tergites 3-7. Female terminalia: Cercus elongate, 2-segmented, segment 1 larger than segment 2. Tergum 9 roughly rectangular. Genital furca strongly sclerotized, Y-shaped, bilobed at proximal apex and median aperture a transparent membrane in distal part. The female genitalia are illustrated for the first time (Figs. 12, 13, 14 and 15). Distribution. Xylomya maculata is known to occur in the following European countries: Denmark, England, France, Poland, Romania, Sweden (southern part), Switzerland, Russia (Moscow Province) (Dusek & Rozkosny 1963; Haenni 1993; Rozkosny 1998; Krivosheina 1999; Hauser & Niehuis 2001). It is known from the Carpathians (Ukraine and Moldavia) and from Asia (Siberia and Anatolia) (Krivosheina 1999; Lindner 1938; Üstüner & Öztürk 2002). Xylomya mlokosiewiczi (Pleske 1925) (Fig. 3, 4, 16, 17, 18 and 19) Material Examined: Turkey: Isparta, Aksu, beside Aksu River, elev. 1250 m, 14 VII 2000, 1 female, T. Üstüner leg (Figs. 3-4 and 19). Distribution. The species had been previously recorded only from Lagodekhi (Lagodechi) in Georgia. It is recorded for the first time from Turkey. Mesonotum with distinct yellow spots on transverse suture, scutellum yellow laterally and apically but black dorsally on basal third of scutellum. Legs predominantly yellow, but all coxae black and apical third of hind femora and tibia and also fore tarsal segments black. Abdomen with yellow spots on posterior corners of tergites 3-7. Female terminalia: Cercus with elongate-ovale shape, two - segmented, segment 1 much larger than segment 2. Tergum 9 N-shaped. Genital furca strongly sclerotized, Y-shaped, rounded at proximal apex and median aperture a transparent membrane in distal part. The female genitalia are illustrated here for the first time (Figs. 16, 17 and 18). DISCUSSION Three species of Xylomya are known from Turkey: X. ciscaucasica (Pleske 1928), X. maculata (Meigen 1804) and X. mlokosiewiczi (Pleske 1925). X. ciscaucasica (Pleske, 1928) and X. mlokosiewiczi (Pleske 1925) are recorded for the first time as fauna of Turkey. The former is known from Vladikavkaz and Alagir in North Ossetia. The latter is known from Lagodekhi in Georgia. Also X. mlokosiewiczi, described by Pleske in 1925, had not been recorded for 86 years. It was redescribed by N. P. Krivosheina in 1999 on the basis of the female type specimen (Krivosheina 1999). The type specimen had been collected by M. Mlokosiewicz in Lagodekhi (Lagodechi), a small town and district in the Kakheti region of the eastern Georgia. Most species of this family are rarely collected, and therefore it is surprising that these species are newly discovered for the fauna of Turkey.

Palaearctic distributions of (✚)—Xylomya ciscaucasica, (䊉)—Xylomya mlokosiewiczi, and (䉱 area designated with dark color)—Xylomya maculata. The Xylomyidae are considered to be endangered because of the loss of old growth forests in Turkey. The finding in the East Mediterranean Region of X. ciscaucasica and X. mlokosiewiczi is rather remarkable, because this species had never before been found outside of the old growth forest of the Caucasus.
