mesosoma
erect hairs present
erect hairs present
The dorsal surface of the mesosoma has erect hairs that differ distinctly from any appressed pilosity. Used in Antkey to separate many myrmicine genera from Cardiocondyla.
hairs not abundant, thick, in pairs
hairs not abundant, thick, in pairs
The dorsal surface of the mesosoma either with or without long erect hairs that differ distinctly from any appressed pilosity. If present, they are either short, thin, or sparse. They are never abundant, thick and arranged in pairs. Used in Antkey to separate other formicine and dolichoderine genera from Nylanderia and Paratrechina.
erect hairs present on mesosoma
erect hairs present on mesosoma
The dorsal surface of the mesosoma has long erect hairs that differ distinctly from any appressed pilosity. The hairs are thick at the base, arranged in pairs, and can be either flexuous or stiff. Used in Antkey to separate Nylanderia and Paratrechina from other formicine and dolichoderine genera.
3 mesosomal convexities
3 mesosomal convexities
The profile of mesosomal dorsum with three distinct convexities (promesonotum, metanotum and propodeum). Used in Antkey to separate Linepithema iniquum from Linepithema humile.
2 mesosomal convexities
2 mesosomal convexities
The profile of mesosomal dorsum with only two distinct convexities (promesonotum and propodeum). The metanotum is not distinctly raised. Used in Antkey to separate Linepithema humile from Linepithema iniquum.
lacking erect hairs
lacking erect hairs
The dorsal surface of the mesosoma lacks erect hairs that differ distinctly from any appressed pilosity. Used in Antkey to separate Cardiocondyla from many myrmicine genera.
dense pelt of short hairs lacking
dense pelt of short hairs lacking
The dorsum of the mesosoma lacking a dense pelt of short, semierect hairs. If there are any hairs other than the long flexuous ones, they are very sparse. Used in Antkey to separate Strumigenys lewisi from Strumigenys godeffroyi.
dense pelt of short hairs
dense pelt of short hairs
The dorsum of the mesosoma has a dense pelt of short, semierect hairs distinct from the very long flexuous hairs. Used in Antkey to separate Strumigenys godeffroyi from Strumigenys lewisi.
metanotal groove impressed
metanotal groove impressed
The metanotal groove is impressed, distinctly separating the propodeum from the promesonotum. Used in Antkey to separate Camponotus sexguttatus from all other Camponotus species.
metanotal groove not strongly impressed
metanotal groove not strongly impressed
The metanotal groove is weakly impressed or not impressed at all. The entire mesosomal dorsal profile forms an unbroken, convex curve. Used in Antkey to separate all other Camponotus species from Camponotus sexguttatus.
