The oribatid mite family Astegistidae is represented in Mongolia by four species in two genera. A new species, Cultroribula taigagica sp. nov., collected from cool temperate forests in Northern Mongolia is described based on adults. In addition, three known species, Astegistes pilosus (C.L. Koch, 1840), Cultroribula dentata Willmann, 1950 and Cultroribula vtorovi Krivolutsly, 1971 are recorded for the first time from Mongolia, which are redescribed along with data on their distribution and ecology. A key to Mongolian species of Astegistidae is given.
AbstractDuring an exploration of soil mite fauna from Khorasan Razavi province, Cheiroseius samani sp. n. was collected from moist soil and litter in an apple orchard in Neyshabur region, northeastern Iran. Diagnosis, description and illustrations are provided for this species. C. samani sp. n. belongs to the subgenus Posttrematus suggested by Karg (1993), having the peritremes extended behind coxae IV. This species also belongs to the Cheiroseius necorniger-complex Karg (1998), having antero-medial part of sternal shield with two semicircular marks anteriorly, and bearing three pairs of simple setae.
