Genus Stichopogon Loew

Stichopogon Loew, 1847: 499 (as a subgenus of Dasypogon Meigen, 1803 ). Type species: Dasypogon elegantulus Wiedemann, 1820 .

Echinopogon Bezzi, 1910a: 131 .

Dichropogon Bezzi, 1910a: 133 .

Ruzanna Richter, 1979: 1240.

The genus Stichopogon is characterized by their size (at 3 mm, the smallest South Korean asilids) and “fragile” or delicate appearance ( Oldroyd, 1972); the isolated strong leg bristles; and well defined abdominal patterns. They are easily separated from the genus Lasiopogon by their wing venation (with a stalked cell m3) ( Fig. 1 ), low facial gibbosity ( Fig. 4 ); and undivided epandria ( Fig. 6 ).

In his monograph of the Palaearctic genus Lasiopogon, Lehr (1984 a, b) lists 20 related East Palaearctic species. Nagatomi (1983) notes two species, Stichopogon gracilifemur, Nagatomi, 1983 and Stichopogon infuscatus, Bezzi, 1910 from Japan.
