mesosoma
macrosetae long and flexuous
macrosetae long and flexuous
macrosetae on mesosoma long and flexuous, strongly tapering to a fine tip (Nylanderia)
promesonotum with 3 pair of spines
promesonotum with 3 pair of spines
The promesonotum is armed with at least three pairs of spines and teeth. Usually the anterior pairs are large and robust, and the posterior pair is smaller. Used in Antkey to separate Acromyrmex from Atta.
mesosoma entirely punctate
mesosoma entirely punctate
The mesosoma is entirely covered in a punctate ground sculpture giving it a uniformly dull appearance. Used in Antkey to separate Monomorium pharaonis and the Monomorium salomonis-group from other Monomorium.
mesosoma with one convexity
mesosoma with one convexity
The promesonotum is composed of one, not two, distinct convexities. Used in Antkey to separate Pheidole flavens and Pheidole moerens from Pheidole fervens and Pheidole teneriffana.
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.
lacking short, thick, flattened hairs
lacking short, thick, flattened hairs
The head and mesosoma lack abundant short, thick and slightly flattened hairs that are light in color. If erect hairs are present, they are sparse, fine and never appearing flattened. Used in Antkey to separate Crematogaster obscurata from Crematogaster scutellaris.
abundant short, thick, flattened hairs
abundant short, thick, flattened hairs
The head and mesosoma have abundant short, thick and slightly flattened hairs that are light in color. Used in Antkey to separate Crematogaster obscurata from Crematogaster scutellaris.
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.
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.
