Notes on the genus Hirschmann, 1989 (Acari, Mesostigmata, Urodinychidae).

The genus Hirschmann, 1989 (Mesostigmata: Uropodina: Urodinychidae) is resurrected for species of the -group. This genus differs from the other taxa of Berlese, 1903 sensu lato based on the shape of the idiosoma and the caudal and dorsal setae. Three species from the -group are transferred to the genus , as (Hirschmann, 1973), , (Hiramatsu, 1980), and (Hiramatsu, 1980), The other seven species from this species group are transferred to , as (Vitzthum, 1926), , (Hiramatsu, 1985), , (Hiramatsu & Hirschmann, 1978), , (Hiramatsu & Hirschmann, 1978), , (Hiramatsu, 1980), , (Hiramatsu & Hirschmann, 1978), and (Hiramatsu & Hirschmann, 1978), The new genus differs from by the shape of the idiosoma and the shape of marginal and dorsal setae. Six species occur in the Oriental Realm and only one species is known from the Neotropical region. The present paper contains the description of a second Neotropical species of ( ) which was found in Peru. The new species differs from its Neotropical congener in the dorsal and marginal setation.
