Nine species of Parallelodemas Faust are reported from China. In addition to the previously recorded Parallelodemasimpar Voss, we found Parallelodemasdocile Faust, Parallelodemasvicinum Faust and the following six species newly described herein: Parallelodemasdimetanssp. n., Parallelodemasfeaesp. n., Parallelodemaspetilumsp. n., Parallelodemasplumosumsp. n., Parallelodemassetifronssp. n. and Parallelodemastumenssp. n.Parallelodemastarsale Voss from Java is transferred to Lepidomyctides Yoshihara and Morimoto (comb. n.). Lectotypes are designated for Parallelodemasdocile, Parallelodemasimperfectum Faust, Parallelodemasperfectum Faust, Parallelodemastardum Faust and Parallelodemasvicinum. Several morphological modifications with unknown functions are documented, illustrated and discussed. Males of some species have special setae on rostrum, antennal scape and mesotarsus. A medially notched epistome apparently occurs in both sexes but seems to wear off in females, probably during the preparation of oviposition sites. The mandible is unusual in having a convex, edentate inner face and incisor-like structures on the outer face.
