image:Plectroctena mandibularis, werker, Tweeling, c.jpg, 230px, ''P. mandibularis'' ''Plectroctena'' is an Afrotropical realm, Afrotropical genus of ants, with most species occurring in the rainforest zones of West and Central Africa. Some species are cryptic or subterranean foragers, while others forage in open grassland terrain. The workers forage singly or in groups of 2 to 3. They nest in the earth at varying depths, or in collapsed logs. They prey mainly on millipedes, including their young or eggs. Colony structure A colony of ''Plectroctena lygaria, P. lygaria'' (a small species of the ''mandibularis''-group) may number in excess of 300 adults. An excavated colony in the Ivory Coast consisted of 277 workers, 8 alate queens, and 42 alate males. Consequently 15% of their number was allocated to reproductives at the specific time. The colony size of ''Plectroctena mandibularis, P. mandibularis'' however, seldom exceeds 50 individuals. Nests In a colony of ''Plectroctena lyga ...
