Comments

The record of S. jacobsoni in southern Vietnam indicates that this species could be much more widespread throughout the Indochinese Peninsula than currently known. Its presence in neighboring countries such as Cambodia and Thailand is likely.

After careful examination of the species’ dentition, using specimens with opened mandibles, we determined that S. jacobsoni belongs to the newly introduced elegantula -complex in the S. leptothrix - group ( Fig. 2D View Fig ). Specimens from other localities should be checked if they share similar morphology.
