Abstract
Two new glomerid species from caves in Cao Bang Province, Northern Vietnam, namely, Hyleoglomerishalang Kuroda, Nguyen & Eguchi, sp. nov. and Hyleoglomerisalba Nguyen, Kuroda & Eguchi, sp. nov., are described. The former is characterized by a distinct body color pattern; telopods with a large, quadrate, medially concave, sparsely setose, central syncoxital lobe; and syncoxital horns approximately 1.5-2.0 times as long as the lobe. The latter is distinguished by its completely troglobiotic form without eyes, an unpigmented body, and a roundly triangular syncoxital lobe of telopods. An identification key is also provided for the cave glomerids of Vietnam.
