REDESCRIPTION OF WINTERSCHMIDTIA WICHMANNI (ACARI: ASTIGMATA: WINTERSCHMIDTIIDAE) FROM AUSTRIA

Abstract

Phoretic deutonymphs of Winterschmidtia wichmanni (Türk and Türk, 1957) (Acari: Winterschmidtiidae) are redescribed based on specimens collected from Pyrrhidium sanguineum (Coleoptera: Cerambycidae) in Austria. While phoretic deutonymphs of W. wichmanni are similar to those of W. nataliae (Zachvatkin, 1941), they diffr in the size of the idiosoma, the microsculpture of the dorsal idiosoma, the length of solenidia ω1 and ω2 on tarsus I, the size of the attachment organ and the absence of sclerotized structures laterad to the attachment organ.
