Two new cave-dwelling species of the feaellid genus Cybella Judson, C. gelanggi sp. nov. and C. weygoldti sp. nov., are described from caves in Malaysia. Like other species of the genus from Vietnam and Cambodia, they possess the unusual morphology of the coxal region in which coxa III is reduced in size, and they lack well-developed plates within the pleural abdominal membrane.
