Three new species of the subgenus Otocepheus (Acrotocepheus) (Acari, Oribatida, Otocepheidae) from China

Abstract

Three new species of subgenus Otocepheus (Acrotocepheus): O. (A.) digitatussp. nov., O. (A.) multigranulatussp. nov., and O. (A.) occultatussp. nov. are proposed and described based on adult material collected from China, and O. (A.) duplicornutus Aoki, 1965 is reported in China for the first time. A key to Chinese species of the subgenus Acrotocepheus is provided.

Two new species and new records of Otocepheidae (Acari, Oribatida) from Yunnan, Southwest China

“…The specimen collected from Yunnan, Southwest China is morphologically coincident (shape of costula, unsmooth genital plates, epimeral setal formula, etc) with E. (E.) mahunkai described and illustrated by Mondal and Kundu (1999) from Darjeeling, Bengal, India, except for the shape of lateral notogastral condyles (trapezoid in our specimen vs. triangular in Mondal and Kundu's description). Considering that there is intraspecific variation in the shape of notogastral or prodorsal condyles in Otocepheidae (Aoki 1967;Zheng and Chen 2020), we identified this specimen as E. (E.) mahunkai, which has not been recorded in China before.…”
