Key to Vietnamese genera of the subfamily Amblyoponinae based on workers. Modified from Eguchi et al. (2014), Eguchi et al. (2015) and Satria et al. (2016).
- Petiole narrowly attached to abdominal segment III (gastral segment I); abdominal segment III above helcium with free anterior face (Fig. 9); frontal lobe completely absent, thus antennal socket in full-face view fully exposed (Fig. 10) => Opamyrma (this genus is now in the subfamily Leptanillinae)
- Petiole broadly attached to abdominal segment III; abdominal segment III above helcium without a conspicuous free anterior face (Fig. 11); frontal lobe present, thus antennal socket in full-face view at least partly concealed (Fig. 12) => 2
- Mandible elongate-triangular, armed with 3 teeth (Fig. 13); in closed position inner margin of mandibles not forming a conspicuous gap against the anterior clypeal margin => Prionopelta
- Mandible linear, armed with more than 3 teeth(Figs. 14, 15, 16); if mandible armed with 3 teeth, the apical teeth forming an elongate and falcate apical blade, and 2nd and 3rd teeth blunt or truncate apically; in closed position inner margin of mandibles separated from anterior clypeal margin by a large gap => 3
- Apex of mandible round, with minute teeth (Fig. 16); body covered with spatulate setae (Fig. 17) => Mystrium
- Apex of mandible with distinct apical tooth/teeth (Figs. 14, 15); body without spatulate setae (Fig. 18) => 4
- A few apical segments of antenna distinctly flattened (Figs. 19, 20); outer surface of middle tibia with thickened peglike setae scattered among normal finer background pilosity => Myopopone
- All of antennal segments terete, not flattened (Figs. 21, 22); outer surface of mesotibia without peglike or spiniform setae (the surface of mesotibia often with relatively long standing setae scattered among background pilosity) => 5
- Anteromedian part of clypeus produced as a clypeal lobe; petiole with a distinct anterior peduncle => Xymmer
- Anteromedian part of clypeus never produced as a clypeal lobe; petiole essentially sessile. => Stigmatomma (=Bannapone)
