petiolar node
petiolar node relatively thick
The petiolar node is relatively thick in profile. Used in Antkey to separate Tetramorium simillimum from Tetramorium caldarium. The character, as it is presently defined, is ambiguous and requires a more detailed examination before its usefulness is confirmed.
petiolar node relatively thin
The petiolar node is relatively thin in profile. Used in Antkey to separate Tetramorium caldarium from Tetramorium simillimum. The character, as it is presently defined, is ambiguous and requires a more detailed examination before its usefulness is confirmed.
petiolar node with apical spine
The petiolar node is armed with a apical single, weakly posteriorly protecting spine. Used in Antkey to separate Odontomachus simillimus and Odontomachus ruginodis from Anochetus mayri.
distinct peduncle and node
The petiole has a clearly separate and distinct peduncle and node. Used in Antkey to separate from many myrmicine genera from Crematogaster.
petiolar node with convex dorsum
The petiolar node has a convex dorsal face and the dorsal profile slopes anteriorly. In Antkey used to separate Crematogaster obscurata from Crematogaster scutellaris.
petiolar node with flat to concave dorsum
The petiolar node has a flat to concave dorsal face. In Antkey used to separate Crematogaster scutellaris from Crematogaster obscurata.
petiole node excised medially
The petiolar node is excised medially to form a pair of dorsolateral spines.
petiole flattened
The petiole appears flattened and lacks a distinction between the peduncle and the node. Used in Antkey to separate Crematogaster from many other myrmicine genera.
propodeum and petiole armed
The propodeum and petiolar node both armed with a pair of short teeth. Used in Antkey to separate Dolichoderus thoracicus from other species of Dolichoderinae and Formicinae.
propodeum and petiole unarmed
The propodeum and petiolar node both lacking a pair of short teeth. Used in Antkey to separate various species of Dolichoderinae and Formicinae from Dolichoderus thoracicus.
