Mycetomoellerius jamaicensis
(André, 1893)
Jamaican Fungus-farming Ant
Mycetomoellerius jamaicensis is a fungus-farming in the tribe Attini, known for cultivating symbiotic fungi as a food source. The belongs to a historically classified under Trachymyrmex but recently recognized as distinct based on molecular and morphological evidence. As with other attine ants, colonies maintain fungal gardens within nests. The species has been documented in the conterminous United States with observations concentrated in the southeastern region.

Identification
Mycetomoellerius jamaicensis can be distinguished from similar attine ants by morphological features associated with the Mycetomoellerius, including characteristics of the mesosomal sculpturing and antennal structure. The was historically placed in Trachymyrmex, from which Mycetomoellerius was separated; accurate identification requires examination of microscopic features and may need expert verification.
Distribution
Conterminous United States, with presence documented in the southeastern region including Florida. The specific epithet 'jamaicensis' suggests a Caribbean origin, though current distribution records focus on mainland North America.
Diet
Fungus-farming ants cultivate symbiotic fungi on substrate brought into the nest; the fungal gardens serve as the primary food source for the colony.
Behavior
Colonies of attine ants maintain fungal gardens within nests, with foraging to collect organic material to substrate the fungal cultures. The farming represents a complex mutualism between the ants and their cultivated fungi.
Ecological Role
As fungus-farming ants, M. jamaicensis participates in nutrient cycling by processing plant material into fungal . The mutualistic relationship with cultivated fungi represents a specialized ecological interaction.
Similar Taxa
- Trachymyrmex septentrionalisFormerly classified in the same ; both are attine fungus-farming ants with overlapping distribution in the southeastern United States. Mycetomoellerius was separated from Trachymyrmex based on molecular phylogenetic and morphological studies.
- Other Attini genera (Acromyrmex, Atta)All cultivate fungi, but Acromyrmex and Atta are with distinct foraging and larger colony sizes; Mycetomoellerius are generally smaller and do not cut leaves.
