The Morphology and Inter‐relationship of the Genera of Syrphid Flies, Recent and Fossil.

Afrotropical flower flies (Diptera: Syrphidae). A new genus and species from Kenya, with a review of the melanostomine group of genera

“…Only two generic identification keys have ever been written for this fauna (Bezzi 1915, Curran 1927, although Hull (1949b) did provide an overview of all flower fly groups. Now, continuing the trend that first began in Europe (Schiner 1860-64; most recent Papp & Darvas 1997-2000 and was followed in the Nearctic (Williston 1885(Williston , 1888(Williston , 1896(Williston , 1908Curran 1934Curran , 1965McAlpine 1987McAlpine , 1990) and most recently Central America (Brown et al -2010, an effort has commenced to revise the Afrotropical fly fauna (Kirk-Spriggs & Mostovski 2010).…”

The flower fly genus Eosphaerophoria Frey (Diptera, Syrphidae)

“…Tambavanna dentiscutellata Keiser, 1958 was based on a single male collected in central Sri Lanka, and he stated its resemblance to Sphaerophoria and some similarities with Ocyptamus (Calostigma), both members of the tribe Syrphini, but referred his new genus to the tribe Bacchini (subfam. Syrphinae) sensu Hull (1949), based on the slightly narrowed abdominal base and reduced alula and anal lobe.…”

Spazigasteroides a new genus from China with a black face and scutellum in the Syrphini (Diptera: Syrphidae)

“…Williston (1886) erects the tribe Bacchini and the tribe Melanostomini, the former consists of the genera with face considerably narrowed below, and abdomen frequently contracted beyond the base, more or less slender; the latter the genera with black face and scutellum. This division was followed subsequently by most workers, although the two tribes respectively comprised of different genera in the classifications of different authors (Brunetti 1923;Shannon 1921Shannon , 1922Shannon , 1923Hull 1949;Goffe 1952;Vockeroth 1969;Knutson et al 1975;Thompson et al 1976;Peck 1988;Cheng et al 1998;Huo et al 2007). Stubbs et al (1983) divide Syrphinae into three tribes: Syrphini (included Chrysotoxini), Bacchini (included Melanostomatini) and Paragini.…”

“…The subfamily Syrphinae has been grouped into many different tribes or subfamilies (Williston 1886;Shannon 1921Shannon , 1922Shannon , 1923Hull 1949;Shiraki, 1949;Goffe 1952;Hartley 1960;Wirth et al 1965;Dusek & Laska 1967;Knutson et al 1975;Smith et al 1980;Stubbs et al 1983;Peck 1988;Vockeroth 1969Vockeroth , 1992Thompson & Rotheray 1998). Wirth et al (1965) transfer Pipizini from Eristalinae to Syrphinae based on the larval feeding habits, which division is accepted by some workers and not by others.…”
