Known from a meager number of type specimens that were collected from the Hoang Lien Son mountains in far northern Vietnam.
Identification
Taylor (2012) - L. hmong is distinguished from the Japanese Lordomyrma azumai by its darker, more uniform coloration, less-intensively sculptured gastral dorsum and proportionately large eyes in the gyne. These taxa are doubtless closely related. They could represent geographical variants of a single species, and this should be considered when future collections from intermediate Chinese localities are assessed. Approximately 2,800 km separate the hmong type locality from extreme southern Japan.

Description
Worker
General features as seen in images. Conformationally very similar to Lordomyrma azumai. The sculpturation and pre-gastral pilosity essentially as described for that species. Pronotal humeral nodules equivalent to those of L. azumai present. Gaster with pilosity as in L. azumai; smooth and strongly reflective, with minute very finely incised micro-striate stellae at the base of each hair. These structures become slightly larger and more dense posteriad. Color more-or-less uniformly dark reddish-brown, the gaster more blackish-brown than elsewhere; legs and antennae, lighter, brighter orange-brown. Dimensions: (holotype, paratype): TL 4.2, 4.4; HW 0.86, 0.87; HL 0.91, 0.93; CI 94, 94; EL 0.19, 0.18; OI 22, 21; SL 0.62, 0.63; SI 72, 72; PW 0.65, 0.0.63; WL 1.22,1.21; DPW 0.28, 0.27; DPpW 0.36, 0.37; GW 1.02, 1.04.
Queen
Generally as seen in images. Differing from the worker similarly to Lordomyrma azumai. Eyes proportionately larger than in that species (OI 25 versus 20). Dimensions: TL 4.6; HW 0.84; HL 0.89; CI 94; EL 0.21; OI 25; SL - ; SI - ; PW 0.68; SW 0.69; WL 1.29; DPW 0.25; DPpW 0.36; GW 1.11.
Type Material
VIETNAM: LAO CAI: Ban Khoang, Sa Pa. (22°21' 0 N, 103°52' 0 E). Holotype, paratype gyne: Entomological Collection of the Institute of Ecology and Biological Resources. Paratype worker: Australian National Insect Collection. Known only from the holotype, a single paratype worker and paratype dealate gyne, collected together at the type locality in the Hoang Lien Son mountains in far northern Vietnam (K. Eguchi Acc Eg07x06-09, 07/x/2006, 1600- 1700m.).
Etymology
Named for the Hmong people of northern Vietnam.
