Ants from Brazzaville, 4°15'33" S 15°17'5" E; collected by Yves Braet & Eric Zassi, from 24h pitfall traps, 19.viii.2007

A total of 46 species from twenty 24h pitfall traps on 19.viii.2007. 

Site details -The transect (yellow line on the large map) was realized in the forest around the GERDIB laboratories (Groupe d'Etude et de Recherche sur la Diversité Biologique; route de l'Auberge Gascogne Château d'eau, Brazzaville; ex-ORSTOM), This forest is rather protected but has been modified by human activities such as construction, vegetables gardening, and other undocumented activities. In some parts the understorey ("sous-bois") vegetation is very dense. The first and last pitfall traps were in open ground; pitfalls 10 to 12 were in the domestic garden of one house). Some of the houses have been used as lodges for visitors (locals or foreigners) and/or scientific work before the last civil war. The airport is very close around 1.5 km distant. The altitude is around 300 meters. From Yves Braet.
