antennal scape
> 10 erect scape hairs
> 10 erect scape hairs
Antennal scapes with more than 10 erect hairs. The hairs may be also be semierect, but are distinguished from the more common appressed pilosity. Separates Nylanderia flavipes, Nylanderia terricola and Nylanderia vividula from Nylanderia guatemalensis and Nylanderia vaga.
scape hairs longer than scape width
scape hairs longer than scape width
The antennal scape has many hairs that are longer than the width of the scape. Used in Antkey to separate Camponotus atriceps from Camponotus planatus.
scape hairs shorter than scape width
scape hairs shorter than scape width
The antennal scape lacks hairs that are longer than the width of the scape. Used in Antkey to separate Camponotus planatus Camponotus atriceps.
scapes 1.5x head length
scapes 1.5x head length
The antennal scapes are extremely long, their length measuring more than 1.5x the length of the head. Used in Antkey to separate Anoplolepis gracilipes and Paratrechina longicornis from other formicine genera.
scapes < 1.5x head length
scapes < 1.5x head length
The antennal scapes of various lengths, from short to long, but never measuring more than 1.5x the length of the head. Used in Antkey to separate other formicine genera from Anoplolepis gracilipes and Paratrechina longicornis.
scape length
scape length
The maximum straight-line length of the scape, excluding the basal
constriction or neck that occurs just distal of the condylar bulb.
scapes barely surpass margin
scapes barely surpass margin
The antennal scapes are relatively short, reaching the posterior head margin but not surpassing it by more than 1/5th their length. Used in Antkey to separate Brachymyrmex JAM-001 from all other Brachymyrmex species.
scapes clearly surpass margin
scapes clearly surpass margin
The antennal scapes are relatively long, surpassing the posterior head margin by more than 1/5th their length. Used in Antkey to separate all other Brachymyrmex species from Brachymyrmex JAM-001.
