Genus Lichtwardtia Enderlein, 1912

Lichtwardtia Enderlein, 1912: 406 . Type species: Lichtwardtia formosana Enderlein,

1912, original designation.

Vaalimyia Curran, 1926: 398 . Type species: Vaalimyia violacea Curran, 1926 [= Dolichopus angularis Macquart, 1842 ], original designation.

NOTES. See Grichanov (2004) and Yang et al. (2011) for diagnosis of the genus

Lichtwardtia . Males differ from females usually in such male secondary sexual characters as variously coloured face (partly or mostly metallic, matt black, densely white or yellow pollinose), face length to width ratio; wing sometimes with a colour pattern, with more or less developed costal swelling at R 1; rarely modified antenna or podomeres (e.g. dilated last two segments of hind tarsus). Females of close species are practically indistinguishable (Tang et al., 2018). A few Afrotropical species have partly black femora or completely black postocular setae; nevertheless, these characters do not correlate with the hypopygium morphology. The Australasian and

Oriental species are rather similar to each other in general habitus, differing reliably in male genitalia. Taking into account a great specific variability of all structures of the hypopygium in all parts of the genus area, Lichtwardtia is most probably a monophyletic group of species.

Tang et al. (2018).
