The present paper deals with two species of oribatid mites of the genus Trichoribates Berlese, 1910 from the subalpine zone of high mountains in Central Japan. Trichoribates aokii n. sp. and Trichoribates hirauchiae n. sp. are proposed on the basis of adults. The first species is characterized by narrow lamellar cusps and translamella, and very closely situated notogastral setae h2 and h3. The second species is readily distinguishable from other closely related species by the specific structure of porose areas A1 and A2, the larger body size, the longer interlamellar and rostral setae, and anteriorly converging lamellae. A key to the Japanese species of Trichoribatesis provided along with data on their geographical distribution and habitat ecology.
