Etymology. The specific name rong is from the Vietnamese rồng meaning “dragon” and is treated as a noun in apposition. The type species of Andreimyrme , A. long, is named using a Chinese word for dragon. These species have similar mandibles and may be eventually recognized as belonging to the same species.

Remarks. The mandibular shape of this new species is unique among females in the genus; only A. silvorientalis sp. nov. has a similar apically dilated mandible. Andreimyrme rong sp. nov. overlaps with the male genotype, A. long, in Chiang Mai, Thailand, although the latter species has not been formally recorded. The extremely dilated mandible shape of this female superficially resembles that of A. long. For this reason, we suspect that A. rong may eventually be recognized as the female for that species, which is why we provided a similar name.
