petiolar peduncle
peduncle relatively long
peduncle relatively long
The petiolar peduncle is long (length distinctly twice or more than height) and does not taper gradually into node. Used in Antkey to separate Cardiocondyla kagutsuchi, Cardiocondyla mauritanica and Cardiocondyla venustula from Cardiocondyla minutior, Cardiocondyla obscurior and Cardiocondyla wroughtonii.
peduncle relatively short
peduncle relatively short
The petiolar peduncle not appearing long (length not twice height), and thickens gradually as it tapers into node. Used in Antkey to separate Cardiocondyla minutior, Cardiocondyla obscurior and Cardiocondyla wroughtonii from Cardiocondyla kagutsuchi, Cardiocondyla mauritanica and Cardiocondyla venustula.
peduncle relatively thick
peduncle relatively thick
The petiolar peduncle 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.

The petiolar peduncle 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.
