scapes surpass posterior eye margin
scapes surpass posterior eye margin
The antennal scapes, when arranged along the anteroposterior axis of the head, extend beyond the posterior head margin. Used in Antkey to separate Hypoponera opaciceps and Pachycondyla species from Hypoponera punctatissima, Hypoponera ragusai and Hypoponera zwaluwenburgi.
6-segmented antenna
6-segmented antenna
Antenna with six segments, including scape. Unique to all Strumigenys and Strumigenys species in Antkey.
7-segmented antenna
7-segmented antenna
Antenna with seven segments, including scape. Unique to all Eurhopalothrix species in Antkey.
3-segmented antennal club
3-segmented antennal club
The three most apical antennal segments are enlarged relative to all preceding segments, forming a distinct club at the end of the antenna. Used to distinguish among myrmicine genera
4-segmented antennal club
4-segmented antennal club
The four most apical antennal segments are enlarged relative to all preceding segments, forming a distinct club at the end of the antenna. Used to distinguish Myrmica species from all other myrmicines in Antkey.
antennal club absent
antennal club absent
The funicular segments filiform or becoming incrementally larger, but never forming a distinct 1-4 segmented club.
scapes do not surpass posterior head margin
scapes do not surpass posterior head margin
The antennal scapes, when arranged along the anteroposterior axis of the head, do not reach the posterior head margin. Used in Antkey to separate Hypoponera punctatissima, Hypoponera ragusai and Hypoponera zwaluwenburgi from Hypoponera opaciceps and Pachycondyla species.

scapes do not surpass posterior head margin
Antennal scapes, when arranged along the anteroposterior axis of the head, do not reach its posterior margin.
scapes surpass posterior eye margin
scapes surpass posterior eye margin
Antennal scapes, when arranged along the anteroposterior axis of the head, easily surpass posterior margin of eye. Separates all the species of Myrmicinae in Antkey from those of Cerapachyinae.
scapes surpass posterior head margin
scapes surpass posterior head margin
Antennal scapes exceed posterior head margin by a distance greater than half eye length. Separates Plagiolepis alluaudi and Plagiolepis pygmae from Plagiolepis exigua.
