A take‐over and infanticide were observed in a South Indian population of Hanuman langurs ( Presbytis entellus ). A one‐male, bisexual troop of langurs (Troop B1) was attacked by a band of two adult males and one subadult male. During the take‐over, the resident male and one elderly female were driven from the troop. The youngest infant, about two months old, was fatally wounded by an attack from the dominant incoming male (S1). However, other young infants in Troop B1 were left unharmed. All three incoming males remained in Troop B1 but the troop appeared to remain functionally one‐male, as S1 did not allow the other adult male to copulate. There was no sign that S1 attempted to eject the other two males from troop B1. © 1993 Wiley‐Liss, Inc.
