Contribution to the knowledge of the oribatid mite genus Eurostocepheus (Acari, Oribatida, Otocepheidae)

Abstract

A new species of the genus Eurostocepheus (Oribatida, Otocepheidae) is described from soil and litter of Tam Dao National Park in Northern Vietnam. Eurostocepheus (Eurostocepheus) wojciechniedbalai sp. nov. is morphologically most similar to E. (E.) mahunkai Mondal & Kundu, 1999 from India in the presence of four pairs of genital setae and medial prodorsal condyles, but differs by the quadrangular, anteromedially excavated lateral notogastral condyles, short interlamellar setae, short notogastral setae c, minute epimeral setae 1a, 2a, 3a, two pairs of epimeral setae on epimere IV, and by the transverse position of the anal setae. Revised generic and subgeneric diagnoses, an identification key to the known taxa, and data on the distribution and ecology of Eurostocepheus are presented.
