propodeal declivity
propodeum with posterior protrusion and concave declivity
propodeum with posterior protrusion and concave declivity
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.
propodeal declivity 2x dorsum
propodeal declivity 2x dorsum
The propodeal declivity is at least twice length of propodeal dorsum. Used in Antkey to separate Lasius from Anoplolepis and Formica.
propodeal declivity < 2x dorsum
propodeal declivity < 2x dorsum
The propodeal declivity is less than twice length of propodeal dorsum. Used in Antkey to separate Anoplolepis and Formica from Lasius.
propodeal dorsal surface not shorter than posterior
propodeal dorsal surface not shorter than posterior
The dorsal face of the propodeum is either longer or approximately equal to the posterior face, but never distinctly shorter. Used in Antkey to separate Linepithema and Iridomyrmex from Tapinoma and Technomyrmex .
propodeal dorsal surface shorter than posterior
propodeal dorsal surface shorter than posterior
The dorsal face of the propodeum is distinctly shorter than posterior face. Used in Antkey to separate Tapinoma and Technomyrmex from Linepithema and Iridomyrmex.
propodeum lacking projecting protrusion
propodeum lacking projecting protrusion
The propodeum may be strongly convex, but it never forms a posteriorly projecting protrusion, and the declivity is convex to flat, but never concave. Used in Antkey to separate various species of dolichoderines and formicines from the Ochetellus glaber complex.
