Key to the South Korean Genera of Asilinae
1. Dorsal occipital hair strongly proclinate; female abdominal tergites 6 – 8 elongated, compressed laterally (as in Astochia) . . . Neoitamus Osten- Sacken, 1878
- Dorsal occipital hair not strongly proclinate; female abdominal tergites 6 – 8 not elongated or compressed laterally or different shape . . . 2
2. Male fore basitarsus with spatulate (spoon-like) bristles; epandrium with conspicuous paralobes and a sagging appearance; ovipositor elongated with five segments . . . Astochia Becker in Becker & Stein, 1913
-Male fore basitarsus without spatulate bristles; epandrium more erect; ovipositor less elongated with fewer than five segments . . . 3
3. Fore basitarsus stout and thickened . . . Asilella Lehr, 1970
-Fore basitarsus not considerably thickened . . . 4
4. Facial gibbosity reduced to mouth margin; epandrial lobe red/orange . . . Aneomochtherus Lehr, 1996
-Facial gibbosity not reduced to mouth margin; epandrial lobe not red/orange . . . 5
5. Sternite 8 of males strongly excised with long medial hair; female ovipositor angulated and compressed, cercus embedded into tergite 9 and sharp on distal apex . . . Eutolmus Loew, 1848
-Sternite 8 of males less excised, or not at all; female ovipositor not angulated; cercus not embedded into tergite 9 . . . 6
6. Dark brown or yellow species; sternite 8 of male slightly excised medially (as in Mercuriana) or with a long fringe of apical hair . . . Machimus Loew
-Dark black or gray species; sternite 8 of male thickened medio-apically, or male with toothed or notched epandrial lobes . . . 7
7. Gray species; male dorsal epandrial lobes with medial dorsal tooth clearly visible; female cercus with spines . . . Philonicus Loew, 1849
-Black species; male dorsal epandrial lobes without notch, or tooth; female cercus rounded as in Machimus, almost as long as tergite 9, without spines . . . Mercuriana Lehr, 1988
