Odontomachus scifictus

Collected in shaded, humid places mostly in degraded, dipterocarp forests. The type locality was near a stream.

Identification
Sorger & Zettel (2011) - Odontomachus scifictus is very similar to Odontomachus philippinus, but differs in the extension of the smooth area on the mesopleuron reaching the meso-metapleural suture, and by the distinct tubercles of the petiole (petiole in anterodorsal aspect widest at tubercles). The distribution of O. scifictusand O. philippinus are separated by another vicariant form, Odontomachus alius.

Distribution
Endemic to the Philippines and only known from the island of Camiguin.

Etymology
This name serves as an homage to early science fiction movies incorporating ants – the first author came across a poster of the movie “Empire of the Ants” (1977) directed by Bert I. Gordon that clearly depicts a giant, dangerously looking Odontomachus species and decided that such prominent display should be memorialized.
