摘　　要：Cubitermes spp. are widely distributed soil-feeding termite species in sub- Saharan Africa which play a fundamental role in soil structure and fertility. A complex of at least four cryptic species （i.e., Cubitermes sp. affunis subarquatus complex of species） has been recently described using molecular markers. In order to investigate the breeding system of these species, five microsatellite markers were used to carry out parentage and re- latedness analyses in 15 Gabonese colonies. Monogamy was confirmed as the predominant reproductive organization in Cubitermes spp. （76% of the colonies）. Within 30% of these monogamous colonies, a high relatedness between reproductives was shown, suggesting that mating between related individuals occurs. However, Cubitermes colonies can deviate from monogamy. Indeed, parental contributions by at least two related reproductives of the same sex were revealed in four colonies and polyandry was demonstrated in two of them. Infiltration of reproductives in the colony is the most plausible explanation for such cases of polygamy in Cubitermes spp.Cubitermes spp. are widely distributed soil-feeding termite species in sub- Saharan Africa which play a fundamental role in soil structure and fertility.
