Annals of the Entomological Society of America 92: 63-76. Pilosity characters, like petiolar characters, are very useful and seem to unite clusters of related species. It is a group generally avoided by students of systematics seeking manageable projects. Although many species can make carton from masticated plant fibers, most use relatively small amounts to form partitions inside the nest or to restrict the opening of a nest in dead wood. It was encountered nine times in the extensive survey, and six of these occurrences were indoors. common name: an acrobat ant - Entomology and Nematology Department You can help Wikipedia by expanding it.

At higher elevations the dominant Crematogaster drop out by about 500 to 1000m, depending on the openness of the habitat. Harada Y., K. Asai, M. Araba, T. Higasayama, and N. Saito.

Thus a synonymization is not a strong statement that two forms are part of the same biological species, which is an unprovable null hypothesis, but instead is an inability to reject the null hypothesis of conspecificity.

The high species diversity and lack of higher level taxonomic structure in the genus has made it one of the intractable messes in the world of ant taxonomy, on par with Solenopsis and Pheidole. Collection code is a relational database linking field that may or may not be printed on the physical label. Japan 65: 169-179. Nature of Kagoshima 41: 199208. 2003. 1996. In contrast, two Costa Rican species make carton nests that sprout epiphytes, forming ant gardens.
