metanotal groove
mesosoma with broad concavity
mesosoma with broad concavity
The dorsum of mesosoma with a deep and broad concavity separating the mesonotum fro the propodeum. The concavity is formed by the strongly convex mesonotum and propodeum, and is more pronounced than an indentation. Used in Antweb to separate Dolichoderus from other dolichoderine and formicine genera. Species in the Ochetellus glaber group approach this character state.
deep broady concavity absent
deep broady concavity absent
The dorsum of the mesosoma is variably shape, either with or without impression. If an impression is present, it is never so pronounced as a deep and broad concavity formed by the strongly convex mesonotum and propodeum. Used in Antkey to separate various dolichoderine and formicine genera from Dolichoderus.
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.
