Colobopsis etiolata
Pale Gate-keeper Ant
Colobopsis etiolata is a species of ant in the genus Colobopsis, originally described by Wheeler in 1904. It belongs to a genus characterized by specialized defensive castes, including 'doorkeeper' majors with enlarged, plug-shaped heads used to block nest entrances. The species is part of the Colobopsis cylindrica group, which includes the well-known 'exploding ants' that exhibit autothysis (self-sacrificial body rupture) as a defensive mechanism. As a member of this group, C. etiolata likely shares the arboreal, canopy-dwelling habits typical of these Southeast Asian forest ants.
Colobopsis impressa
Common Gate-keeper Ant
Colobopsis impressa is a species of arboreal ant in the subfamily Formicinae, commonly known as the Common Gate-keeper Ant. The species belongs to a genus noted for specialized defensive morphologies, including major workers with plug-shaped heads used to block nest entrances. While detailed species-level studies are limited, the species has been documented across Southeast Asian forests. Its biology appears consistent with the broader Colobopsis cylindrica species group, though specific behavioral observations for C. impressa remain sparse.
Colobopsis papago
Colobopsis papago is a species of ant in the genus Colobopsis, family Formicidae. The species was first described by William S. Creighton in 1953. Like other members of the genus, it exhibits the characteristic morphological traits associated with the Colobopsis group, including specialized major workers with modified heads. The species is part of a genus known for diverse defensive strategies, though specific behavioral documentation for C. papago remains limited.
