Stegomyrmex manni

Stegomyrmex manni has been found on the forest floor of mature rainforests in Costa Rica, Panama, and Colombia. Longino found specimens of S. manni in Winkler samples of sifted litter from the forest floor collected at Manuel Antonio National Park, Carara Biological Reserve, Penas Blancas east of Monteverde, and Hitoy Cerere Biological Reserve, all in Costa Rica. An alate gyne was collected at La Selva Biological Station. (Feitosa et al. 2008)

Identification
Feitosa et al. (2008) - The combination of the relatively high promesonotumin side view, propodeal spines directed posteriorly, and propodeal spiracles strongly projected laterally separate this species from the other in the genus.

Distribution based on Regional Taxon Lists
Neotropical Region: Colombia, Costa Rica, Ecuador, Honduras, Panama.

Biology
Holldobler and Wilson (1986) illustrated and discussed the special soil-binding setae of S. manni  (cited as Stegomyrmex connectens).
