A new diagnosis of <em>Schalleriella</em> (Acari: Oribatida: Microzetidae) and a new species from Vietnam

Abstract

A new species of oribatid mite, Schalleriella vietnamica sp. nov., is proposed and described from dark loamy soil of a lagerstroemia forest in Cat Tien National Park (southern Vietnam). This represents the first finding ofSchalleriella in the Oriental region. The genus currently comprises only the type species, Schalleriella grabouwensis, from which S. vietnamica differs by the morphology of the lamellar apices and rostral setae and by the presence of an interlamellar tubercle, longitudinal notogastral lines and areoles in the anogenital region. A new generic diagnosis of Schalleriella is presented.
