A new species of the genus Meristolohmannia (Oribatida: Lohmanniidae) is described from litter of a secondary forest in Macao of southern China; M. macaoensis Ermilov sp. nov. differs from M. abbreviata Chen, Yang & Xie, 2010 by the comparatively longer rostral setae than the lamellar, interlamellar and posterior exobothridial setae, bothridial setae with well-developed branches, reticulate notogaster surface, number and morphology of subcapitular setae, nine pairs of genital setae and the smaller body size. An identification key to the known species of Meristolohmannia is provided. Lohmannia (Lohmannia) corallium Nakatamari, 1982 is recorded in the Oriental region for the first time; its supplementary description is provided based on material from China, and the revised diagnostic traits for this species are also proposed.
