New species of Dolicheremaeus (Acari, Oribatida, Otocepheidae) from Vietnam

Two new species of the genus Dolicheremaeus (Oribatida, Otocepheidae)—D. gialaiensis n. sp. and D. kbangensis n. sp.—are described, based on adults collected from forest litter in the Kon Chu Rang Nature Reserve, central Vietnam. Dolicheremaeus gialaiensis n. sp. characterized by the unusual sculpturing (small, dense, conical tubercles) of the prodorsum, notogaster, and anogenital region. Dolicheremaeus kbangensis n. sp. differs from the related species D. baloghi and D. lineolatus by the notogastral sculpturing, the morphology of the bothridial seta, and the length of the notogastral setae. An identification key to species of Dolicheremaeus from Vietnam is provided.
