Characteristics
The Dacetini shares the following synapomorphies with the other members of the dacetine tribe group (Bolton 2003):- Head anterior to antennnal sockets strongly narrowed from side to side
- Masticatory margins of mandibles oppose but do not overlap when mandibles fully closed
- Trigger hairs on labrum or mandible
- Specialized labral shape
- Preocular carina present
In addition, the tribe has the following apomorphies:
- Mandible with a medially projecting cuticular basimandibular process on inner margin close to base (an extrusion of the mandible)
- Dorsum of labrum with one or two medial impressions that receive the basimandibular processes when the mandibles are fully closed
