Description of Preadult Stages (Protonymphs and Deutonymphs) of Discourella Radnaensis (Willman, 1941) Species (Acarina: Anactinotrichida: Uropodina)
Description of Preadult Stages (Protonymphs and Deutonymphs) of Discourella Radnaensis (Willman, 1941) Species (Acarina: Anactinotrichida: Uropodina) Discourella radnaensis species was described by Willmann from Slovenia, Radna city in 1941, the holotype being female. Since then, the species has not been collected, probably because Uropodina faunal studies in the Balkans were very few. Acarologic material was collected in Serbia, Djerdap National Park, Mount Veliki Strbac (768 m altitude), from litter of mixed deciduous forest and the bark of the decomposing trunk of deciduous trees. In addition to a female, individual protonymphs and deutonymphs were collected. Discourella radnaensis species is thus recorded for the first time in the fauna of Serbia, and pre-adult stages (protonymphs and deutonymphs) are described for the first time in literature.
