Identification
Sorger & Zettel (2011) - A member of the Odontomachus infandus group. Odontomachus schoedli is only known from the western mountain ranges of northern Luzon. In Benguet it is sympatric with Odontomachus infandus. The main differences between these two species are the striation of the pronotum, which is transverse in O. schoedli but more or less longitudinal in O. infandus, and the shape of the petiole, which is remarkably short and with a very straight anterior face of the node (including spine) in O. schoedli, whereas it has a longer, curved spine in O. infandus (only weakly developed in the smallest specimens). The uniformly light chocolate brown colour of head and mesosoma of O. schoedli is striking, but we have seen a few specimens of O. infandus from northern Luzon with the same colouration.

Etymology
This species is named for our late colleague Stefan Schödl, former curator for Hymenoptera at the Natural History Museum Vienna, who collected a major part of the type series.
