E

erect hairs

[Antwiki.org] Refers to a hair that stands straight up, or nearly so, from the body surface.

erect hairs lacking on mesosoma (Monomorium)

The dorsal surface of the mesosoma may have appressed pilosity, but it lacks erect hairs. Used to distinguish species in the Monomorium salomonis group (Monomorium salomonis and Monomorium subopacum) from all other Monomorium species in Antkey.

erect hairs lacking on pronotum and mesonotum (Brachymyrmex)

The dorsal surface of the mesosoma may have appressed pilosity, but it lacks erect hairs. Used to distinguish Brachymyrmex JAM-001 from all other Brachymyrmex species in Antkey.

erect hairs on pronotum and mesonotum (Brachymyrmex)

The dorsal surface of the mesosoma has erect hairs that differ distinctly from any appressed pilosity. Used to distinguish all other Brachymyrmex species in Antkey from Brachymyrmex JAM-001.

erect hairs present (Monomorium)

The dorsal surface of the mesosoma has erect hairs that differ distinctly from any appressed pilosity. Used to distinguish all other Monomorium species in Antkey from species in the Monomorium salomonis group (Monomorium salomonis and Monomorium subopacum).

erect hairs present on mesosoma (Myrmicinae)

The dorsal surface of the mesosoma has erect hairs that differ distinctly from any appressed pilosity. Used to distinguish among myrmicine genera in Antkey.

eye

In Antkey generally refers to the compound eyes located at or near the lateral margin of the face. If present, it is composed of one to many individual facets.

eye length about equal to 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 less 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).

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 at or above midline of head

The eyes are situated distinctly below midline of head. Used in Antkey to separate Ectatomminae from Ponerinae.

eyes below midpoint (Linepithema)

In full face view, the midline of the eye is distinctly below the midline of the head, measured in a longitudinal line from a point tangential to the posterior margin of the head to the anterolateral corner of the clypeus. Used in Antkey to separate Linepithema species from Iridomyrmex anceps.

eyes break outline of head

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 composed of 1-3 facets

The eye is minute (composed of 1-3 facets), but visible. The ommatidia are distinctly pigmented.

eyes greater than three facets

The eye is small to large, but always composed of more than three facets.

eyes inside outline of head

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.

eyes large (greater than five facets)

The eye is small to large, but always composed of more than five facets. Used in Antkey as a coarse filter to separate many different species across all subfamilies.

eyes large (Technomyrmex)

The eye length is distinctly greater than length of cephalic hairs at same level on head. Used in Antkey to separate Technomyrmex vitiensis from Technomyrmex albipes.

eyes minute

Eyes with 3 or fewer facets.

eyes not unusually large

The eyes may be large, but they are distinctly less than half the head length. Used in Antkey to separate Myrmicinae from Pseudomyrmecinae.

eyes on lower margin of scrobe

The eyes are situated on the lower (ventral) margin of antennal scrobe. Used in Antkey to separate Strumigenys from Eurhopalothrix.

eyes on upper margin of scrobe

The eyes are situated on the upper (dorsal) margin of antennal scrobe. Used in Antkey to separate Eurhopalothrix from Strumigenys.

eyes situated at apex of scrobe

The eyes situated at or very close to the apex (posterior-most region) of the antennal scrobe. Used in Antkey to separate Cephalotes from Cyphomyrmex.

eyes situated below scrobe near midline

The eyes situated near midline of lower (ventral) margin of antennal scrobe. Used in Antkey to separate Cyphomyrmex from Cephalotes.

eyes small (five or fewer facets)

The eyes small but distinct, composed of 1-5 facets. Used in Antkey as a coarse filter to separate many different species across all subfamilies.

eyes small (Technomyrmex)

The eye length is not distinctly greater than length of cephalic hairs at same level on head. Used in Antkey to separate Technomyrmex albipes from Technomyrmex vitiensis.

eyes unusually large

The eyes are extremely large (approximately half head length). Used in Antkey to separate Pseudomyrmecinae from Myrmicinae.
