petiolar node reduced or absent
petiolar node reduced or absent
The petiolar node greatly reduced or absent, the anterior face absent or at most indistinct. Used in Antkey to separate Brachymyrmex, Tapinoma and Technomyrmex from various other genera in Dolichoderinae and Formicinae.
petiolar node present
petiolar node present
The petiolar node present and with distinct anterior and posterior faces. Used in Antkey to separate various genera in Dolichoderinae and Formicinae from Brachymyrmex, Tapinoma and Technomyrmex.
postpetiole high with ventral bulge
postpetiole high with ventral bulge
The postpetiole, in profile view, is as high as petiole and with a distinct ventral bulge. Used in Antkey to separate Cardiocondyla emeryi, Cardiocondyla obscurior and Cardiocondyla wroughtonii from all other Cardiocondyla species.
postpetiole attached to lower gastral surface
postpetiole attached to lower gastral surface
The postpetiole is attached to the lower surface of the gaster. Used in Antkey to separate all other myrmicine genera from Crematogaster.
postpetiole attached to upper gastral surface
postpetiole attached to upper gastral surface
The postpetiole is attached to the upper surface of the gaster. Used in Antkey to separate Crematogaster from all other myrmicine genera.
postpetiole sides angulate
postpetiole sides angulate
In dorsal view, the sides of the postpetiole are angulate giving the postpetiolar disc a hexagonal appearance. Used in Antkey to separate Cardiocondyla kagutsuchi and Cardiocondyla mauritanica from Cardiocondyla venustula.
postpetiole lacking spongiform
postpetiole lacking spongiform
The postpetiole lacking distinct spongiform. Used in Antkey to separate Strumigenys eggersi and Strumigenys margaritae from other Strumigenys species.
postpetiole low lacking ventral bulge
postpetiole low lacking ventral bulge
The postpetiole, in profile view, is lower than petiole and lacking a distinct ventral bulge. Used in Antkey to separate Cardiocondyla kagutsuchi, Cardiocondyla mauritanica and Cardiocondyla venustula from all other Cardiocondyla species.
postpetiole not swollen
postpetiole not swollen
In dorsal view, the postpetiole not appearing swollen, not wider than long and not conspicuously broader than the petiole. Used in Antkey to separate various myrmicine genera from Cardiocondyla.
postpetiole spines rounded
postpetiole spines rounded
In dorsal view, the sides of the postpetiole are rounded, giving the postpetiolar disc a more ovoid than hexagonal appearance. Used in Antkey to separate Cardiocondyla venustula from Cardiocondyla kagutsuchi and Cardiocondyla mauritanica.
