gaster
gaster with pale spots
gaster with pale spots
The gaster with yellowish white spots on lateral portions of second tergite. Used in Antkey to separate Camponotus sexguttatus from all other Camponotus species.
erect hairs dense
erect hairs dense
Erect hairs dense on head, mesosoma and gaster. Used in Antkey to separate species of Camponotus.
erect hairs sparse
erect hairs sparse
Erect hairs sparse on head, mesosoma and gaster. Used in Antkey to separate species of Camponotus.
petiole obscured by gaster
petiole obscured by gaster
The petiole, or most of the petiole, may occasionally be obscured by the gaster. This condition is often the case for species of Brachymyrmex, Nylanderia, Tapinoma and Technomyrmex (all of which have a single waist segment). Used in Antkey to separate the aforementioned genera from all others.
gaster concolorous
gaster concolorous
The gaster is concolorous, uniform or nearly uniform in color, lacking both (1) dark transverse bands running near posterior margins of tergites that contrast with the rest of gaster and body, and (2) yellowish white spots on lateral portions of second tergite. Used in Antkey to separate Camponotus atriceps, Camponotus planatus and Camponotus rectangularis from Camponotus sexguttatus and Camponotus variegatus.
gaster variegated
gaster variegated
The gaster is variegated with dark transverse bands running near posterior margins of tergites that contrast with the paler yellow of the rest of gaster and body. Used in Antkey to separate Camponotus variegatus from all other Camponotus species.
gaster with dense pubescence
gaster with dense pubescence
The first gastral tergite is covered with dense pubescence, giving it a dull appearance. Used in Antkey to separate Brachymyrmex minutus and Brachymyrmex obscurior from Brachymyrmex heeri and Brachymyrmex patagonicus. Also used to separate Nylanderia bourbonica, Nylanderia fulva and Nylanderia vaga from all other Nylanderia species.
gaster punctate
gaster punctate
The first gastral segment is entirely punctate. Used in Antkey to separate Strumigenys eggersi from Strumigenys gundlachi.
gaster smooth
gaster smooth
The first gastral segment is smooth and lacking punctation over its entire surface. Used in Antkey to separate Strumigenys gundlachi from Strumigenys eggersi.
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.
