Brachyponera tianzun (Terayama, 2009) |
Nests have been found in soil and under stones.
Identification
Terayama (2009) - Number of mandibular teeth varies 9 or 10 in workers. This species is separated from Euponera sharpi by the angulate posterodorsal corner and much steeply sloped posterior margin of propodeum. Rather it resembles Euponera sakishimensis from the Ryukyus, Japan, and Euponera pilosior from Japan and Korea. But it is separated from the latter two by the narrow dorsal surface of propodeum and triangular subpetiolar process.
