Comments

The record of S. assamensis in northern Vietnam extends its native range south-eastward. Its presence in the states Assam and Nagaland in India and northern Myanmar is likely.

Following the revision of the Strumigenys leptothrix -group and the introduction of the species complexes within the group, S. assamensis likely belongs to the leptothrix -complex, but a formal assessment using specimens of opened mandibles is still recommended. All specimens in our hands have fully closed mandibles. Placing specimens against backlight suggests the observation of a principal dental row of around 7 teeth, followed by a series of small teeth and denticles, terminating in a small apical tooth.
