New records of Dolichopodidae (Diptera) from Russian Primorye and notes on some Chinese species
A new material of Dolichopodidae has been recently found and identified, and includes 53 species; five species are found for the first time in Russia ( Amblypsilopus janatus , Argyra arrogans , Dolichopus aubertini , Medetera flavigena , Micromorphus jinshanensis ), and three species in the Primorsky Territory ( Diaphorus nigricans , Dolichopus punctum , Neurigona micropyga ). In total, nearly 170 species are recorded from Russian Primorye that apparently makes up 80-90% of actual Dolichopodidae fauna of this Territory. All Russian and Chinese species of the Hercostomus cyaneculus group are transferred to the genus Poecilobothrus Mik, 1878 (comb. n.): P. arcticus (Yang, 1996), P. brevipilosus (Yang et Saigusa, 2002), P. brunus (Wei, 1997), P. cucullus (Wei, 1997), P. cyaneculus (Wei, 1997), P. flaveolus (Negrobov et Chalaya, 1987), P. lii (Yang, 1996), P. longipilosus (Yang et Saigusa, 2001), P. luchunensis (Yang et Saigusa, 2001), P. mentougouensis (Zhang, Yang et Grootaert‚ 2003), P. palustrus (Wei, 2006), P. potanini (Stackelberg, 1934), P. pterostichoides (Stackelberg, 1934), P. saetosus (Yang et Saigusa, 2002), P. singularis (Yang et Saigusa, 2001), P. zhejiangensis (Yang, 1996). Poecilobothrus brevipilosus is synonymized with P. pterostichoides (syn.n.). Poecilobothrus flavifemoratus Grichanov et Tonguc, 2010, subspecies of P. varicoloris (Becker, 1917) is raised to a species level (stat.n.). This paper provides also distribution pattern for each collected species.
