Palaearctic species of the genus Medetera (Diptera: Dolichopodidae)

Abstract

An updated checklist and a revised key to the males of Palaearctic species of the genus Medetera including all 180 species and 3 subspecies are provided; 27 species are included in the key for the first time. Medetera belgica Parent, M. bilineata Frey, M. kowarzi Negrobov, M. miki Negrobov, M. peloria Negrobov, M. sphaeropyga Negrobov, M. tarasovae Negrobov, and M. thunebergi Negrobov, stat. resurr., are removed from synonymy based on the differences in the male genitalia.

A new species of Medetera Fischer von Waldheim, 1819 (Diptera: Dolichopodidae) from Iran

“…The absence of strong setae on all legs is characteristic of the closest genus Cyrturella Collin, 1952, but the latter is remarkable in having subequal in length segments 1 and 2 of hind tarsus in both sexes (Grichanov, 2016). Following the key to Palaearctic species (Negrobov & Naglis, 2016), the new species is close to M. glaucelloides Naglis, 2013 described from Turkey, which has many colour differences from the new species in addition to morphological differences. It is worth noting that all specimens from Turkey collected in 1985 by Wolfgang Schacht (Zoologische Staatssammlung München) and studied by Stefan Naglis were originally stored in 70% alcohol, but dried and mounted on pin for the examination and for further conservation (Naglis, 2010).…”

“…It was reviewed by Negrobov & Stackelberg (1972) for the Palaearctic Region. Negrobov & Naglis (2016) provided recently a revised key to Medetera species of the Region.…”

An annotated checklist of Dolichopodidae (Diptera) of Yakutia (Siberia) with some new records

“…Bickel [1985] considered this name as synonym of Nearctic and Neotropical Medetera veles Loew, 1861, examining the holotypes of the two species. Nevertheless, Negrobov and Naglis [2016] raised M. bilineata from synonymy, mentioning the fine difference in setation of male epandrial lobe. Negrobov, 1972 REFERENCES.…”

New records of long-legged flies (Diptera, Dolichopodidae) from Tyva Republic (Russia, Siberia)

“…Type locality: Scania, "in Ostrog ad Wadstena; Botnia orientali ad Johannis Ro prope Tormea" [Sweden; Denmark]. Palaearctic: Austria, Belgium, Czech, Denmark, Egypt, Estonia, Finland, France, Georgia, Germany, Greece, Hungary, Iran, Israel, Morocco, Netherlands, Norway, Poland, Romania, Russia (Adygea, Chechnya, Crimea, Kabardino-Balkaria, Karelia, Krasnodar, Leningrad, Novgorod, Pskov, Ryazan, Stavropol, Voronezh) (Negrobov, 1985). The material from Tyva and a male from Yakutia have some fine differences from the typical form and can represent an undescribed species.…”
