ant morphology
Some morphological terms associated with the head and face.
eye length greater than malar distance
eye length greater than malar distance
The eye length (measured as the greatest diameter in full face view) is approximately equal to the malar distance (distance between anterior border of eye and anterolateral margin of clypeus). Used to separate Brachymyrmex heeri and Brachymyrmex patagonicus from Brachymyrmex obscurior.
eye length > malar distance
eye length > malar distance
The eye length (measured as the greatest diameter in full face view) is greater than the malar distance (distance between anterior border of eye and anterolateral margin of clypeus).
eyes absent
eyes absent
There are no pigmented ommatidia visible on the head. If a facet is visible, it not distinctly pigmented. Used in Antkey to separate Amblyopone zwaluwenburgi, Prionopelta antillana, Cerapachys biroi and Hypoponera zwaluwenburgi from all other species.
eyes below face midline
eyes below face midline
The eyes are situated distinctly below midline of head. Used in Antkey to separate Ectatomminae from Ponerinae.
eye midline below face midline
eye midline below face midline
In full face view, the midline of the eye is distinctly below the midline of the head. Used in Antkey to separate Linepithema species from Iridomyrmex anceps.
eye breaks face outline
eye breaks face outline
In full face view, the lateral margin of the head is interrupted by the eye, such that the eye breaks the outline of the head.
eyes minute (1-3 facets)
eyes minute (1-3 facets)
The eye is minute (composed of 1-3 facets), but visible. The ommatidia are distinctly pigmented.
eyes > 3 facets
eyes > 3 facets
The eye is small to large, but always composed of more than three facets.
eye does not break face outline
eye does not break face outline
In full face view, the lateral margin of the head is not interrupted by the eye, such that the eye entire eye is within the outline of the head.
