Dolichoderus bakhtiari

The only known collection of this species (the type series) were foraging on leaves of shrub trees in a primary upland evergreen forest at about 800 m a.s.l. in Nakhon Ratchasima Province, Northeastern Thailand.

Identification
Dolichoderus bakhtiari is most similar to Dolichoderus taprobanae in general appearance as they share some common characters like reddish to yellowish body color; head microreticulate with smooth and shiny interspaces; relatively small body size; dorsally ﬂat pronotum; nearly right-angled propodeal junction.

However, D. bakhtiari can be easily separated from D. taprobanae by the following combination of characters:
 * body larger in size (TL 3.14–3.63 mm, HL 0.73–0.79 mm, HW 0.6–0.76 mm) vs. body smaller in size (TL 2.51–2.93 mm, HL 0.66–0.69 mm, HW 0.49–0.52 mm) in D. taprobanae
 * head slightly longer than broad vs. head slightly shorter than broad
 * body entirely yellowish brown vs. vertex of head and gaster dark brown
 * dorsal outline of propodeum weakly convex vs. dorsal outline of propodeum straight
 * lateral face of pronotum relatively smooth with more developed of frontal carinae vs. lateral face of pronotum punctate with less developed of frontal carinae
