<paragraphid="3357DBD0EC6435AB70AA6B7A8E9CEE7E"pageNumber="20">This species occurs in lowland rainforest to cloud forest. It is known most abundantly from baits on the forest floor, and major workers are often found with minor workers at baits. Minor workers are also occasionally collected in Winkler samples of sifted leaf litter. Isolated minor workers from the Sierra Madre de Chiapas (see Comments), tentatively identified as this species, were also collected in beating samples.</paragraph>

<paragraphid="CCDDBA78ECB4B437F1F2907FD2389A8E"pageNumber="20">This species is most thoroughly known from rainforest areas of northern Chiapas, Mexico. Isolated minor workers from the Sierra Madre de Chiapas are tentatively identified as this species, but there are slight differences in morphology and no major workers have been collected to support the identification.</paragraph>
