petiole length
petiole as tall as long
The petiole, in profile, is approximately as tall as it is long. The length is measured from the most anterior section of the petiolar peduncle to the most posterior section of the petiolar node, and the height is measured from the apex of the petiolar node to its ventral margin. Used in Antkey to separate Monomorium liliuokalanii from Monomorium ebeninum and Monomorium floricola.

The length is measured from the most anterior section of the petiolar peduncle to the most posterior section of the petiolar node, and the height is measured from the apex of the petiolar node to its ventral margin. Used in Antkey to separate Monomorium ebeninum and Monomorium floricola from Monomorium liliuokalanii.
