Lateral view of gaster, adult worker. The first gastral tergite is marked by only sparse pubescence, giving it a shiny appearance.andnbsp;Used in Antkey to separate Brachymyrmex heeri and Brachymyrmex patagonicus from Brachymyrmex minutus and Brachymyrmex obscurior. Also used to separate all other Nylanderia from Nylanderia bourbonica, Nylanderia fulva and Nylanderia vaga.
Lateral view of propodeum, adult worker. The propodeum forms a posteriorly projecting protrusion (a) which causes the propodeal declivity (b) to be concave. Used in Antkey to separate species in the Ochetellus glaber complex from various species of dolichoderines and formicines.
Lateral view of thorax / mesosoma, adult worker. Dorsum of lacking deep and broad concavity. Photo by April Nobile, Antweb.org, modified.
Lateral view of propodeum, adult worker. Propodeum and petiolar node armed with pairs of short teeth.
Anterior dorsal view of mandibles, adult worker. Mandible shape linear. Photo by April Nobile, Antweb.org, modified.
Anterior dorsal view of mandibles, adult. Mandibles linear and inserted towards the middle of the anterior head margin (arrow). Note apical fork on one mandible.
Multiple views of petiole, adult worker. The petiolar node is armed with a apical single, weakly posteriorly projecting spine. Used in Antkey to separate Odontomachus simillimus and Odontomachus ruginodis from Anochetus mayri.
Lateral view of gaster, adult worker. Distinct constriction lacking between abdominal segments 3 and 4.
