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

The genus Hirschmann, 1989 (Mesostigmata: Uropodina: Urodinychidae) is resurrected for species of the -group.

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.

Catalogue of juvenile instars of oribatid mites (Acari: Oribatida)the next decade (20142023).

In its traditional, paraphyletic context (sans Astigmata), oribatid mites comprise more than 11,000 known species (Subas 2022). They are largely fungivores and decomposers in organic horizons of soil and have a plesiotypic ontogeny that includes four active, free-living juvenile instars. In a taxonomically organized 2014 catalogue, we summarized literature resources concerning the 805 species for which ontogenetic data (mainly morphological) were available.
