Crematogastrini

Crematogastrini is distinguished from other myrmicine tribes primarily by a combination of mandibular and clypeal characters, though precise tribal-level diagnostic features require expert examination. The tribe includes genera with highly variable morphology, from the compact, heart-shaped gaster of Crematogaster species to more elongate forms in other genera. Workers generally possess a well-developed sting and a distinct postpetiole. Identification to genus level is necessary for practical field recognition, as no single visual character unifies all Crematogastrini at the tribal level.

Habitats range from tropical rainforest canopies to temperate ground nests, reflecting the ecological breadth of constituent genera. Many species are arboreal, nesting in dead wood, hollow stems, or constructed carton nests on vegetation. Others occupy soil, leaf litter, or rotting logs. The tribe shows highest diversity in tropical and subtropical regions.

Global distribution with greatest diversity in tropical regions, particularly the Neotropics, Afrotropics, and Indo-Malayan region. Present on all continents except Antarctica.

• MyrmiciniBoth are tribes within Myrmicinae; Myrmicini includes the genus Myrmica and is distinguished by different mandibular dentition and petiole structure, though definitive separation requires detailed morphological examination.
• AttiniAnother myrmicine tribe containing the fungus-growing ants; Attini possess specialized adaptations for fungal cultivation not found in Crematogastrini, including modified cuticular crypts for carrying symbiotic fungi.
• PheidoliniA myrmicine tribe with overlapping geographic ranges; Pheidolini typically exhibit different clypeal and antennal structures, and often show reduced sting development compared to many Crematogastrini.
