[Antwiki.org] An informal collective term for the one or two isolated and reduced abdominal segments that occur between the mesosoma and gaster. When only the petiole (AII) is isolated the waist is said to be one-segmented, but in those taxa where the postpetiole (AIII) is also separated the waist is said to be two-segmented.
- waist hidden
Waist obscured by the overhanging gaster. This condition occurs in several dolichoderine and formicine genera, both of which have have 1-segmented waists.
- waist with one segment
The mesosoma and gaster connected by a single waist segment referred to as the petiole (abdominal segment 2). Used in Antkey to separate Amblyoponinae, Dolichoderinae, Ectatomminae, Formicinae and Ponerinae from Cerapachys, Myrmicinae and Pseudomyrmecinae.
- waist with spongiform
Spongiform is attached to at least some portion of the waist. Used in Antkey to separate Strumigenys and Strumigenys from Cyphomyrmex and Eurhopalothrix.
- waist with two segments
The mesosoma and gaster connected by two waist segments referred to as the petiole and postpetiole (abdominal segments 2 and 3). Used in Antkey to separate Cerapachyinae, Myrmicinae and Pseudomyrmecinae from Amblyoponinae, Dolichoderinae, Ectatomminae, Formicinae and Ponerinae.
- waist without spongiform
Spongiform is entirely lacking from all portions of the waist. Used in Antkey to separate Cyphomyrmex and Eurhopalothrix from Strumigenys.
- worker caste
- worker caste bimorphic
Refers to a worker caste which shows a bimodal variation in size with a distinct small forms (minor workers) and large forms (major workers), but little to no variance in between. In general majors differ from minors in overall body length as well as in having relatively larger heads. The only bimorphic taxa in Antkey are Pheidole and some species of Cephalotes.
- worker caste monomorphic
Refers to a worker caste which shows a no appreciable variation in size.
- worker caste polymorphic
Refers to a worker caste which shows a large, continuous range in size from small to large workers. In general majors differ from minors in overall body length as well as in having relatively larger heads. Polymorphic taxa in Antkey include Anoplolepis custodiens, Acromyrmex, Atta, Camponotus, some Cephalotes species, Monomorium destructor, and all Solenopsis species except for Solenopsis papuana.
