New data on the taxonomy and fauna of Palaearctic species of the genus Thrypticus (Diptera: Dolichopodidae)

Abstract

A new species, Thrypticus mongoliensis Negrobov, Selivanova et Maslova, sp. n. is described from Mongolia. According to the Palaearctic table of Negrobov, Stackelberg, published in 1971, the new species is close to the Thrypticus atomus Frey, differing in the form and chetotaxy of surstyli. Thrypticus atomus has straight surstyli, with 6 bristles and hairs at apex, while the new species has curved surstyli, more than 40 setae and hairs. On the morphology of the hypopygium, the new species is close to Thrypticus smaragdinus Gerstaecker, 1864, differing in the structure and chetotaxy of the surstyli, including curved and broadened at the base of the surstyli. Three species are listed for the fauna of Mongolia for the first time: Thrypticus intercedens Negrobov, 1967, Thrypticus emiliae Negrobov, 1971 in Negrobov et Stackelberg, 1971 and Thrypticus politus Negrobov, 1967. Thrypticus cuneatus (Becker, 1917) is recorded for the central part of the European part of Russia for the first time. Thrypticus bellus Loew, 1869 are indicated for the faunas of Karelia, Rostov and Lipetsk regions, Kyrgyzstan, Tajikistan and Uzbekistan for the first time. Thrypticus virescens Negrobov 1967 and Thrypticus laetus Verrall, 1912 are new records for Ryazan Region
