Odontomachus malignus
species group
Diagnosis: Palp formula 4, 4. Head short, posteriorly with pair of tubercles. Mandibles long with long and sharp apical and subapical teeth. Antennae relatively short. Mesosoma not depressed. Pronotum with delicate sculpture. Petiole comparatively small and low.
Diversity and distribution: This group contains only one species,
O. malignus
from the western Pacific area.
Notes: Brown (1976) included
O. malignus
in the
O. infandus
species group, mainly because of its mandibular structures. However, the short head, short scape, and comparatively high and stout mesosoma differ considerably from both the
O. infandus
and the
O. rixosus
species group. The combination of morphological characters and the unique biology justify the erection of a separate species group.
