Paraschizogynium plumachela sp. nov., collected from passalid, tiger, and stag beetles (Coleoptera: Passalidae, Carabidae: Cicindelinae, Lucanidae) in China, is described. This is the second species of the genus Paraschizogynium Hunter & Rosario, 1987, and the first record of Schizogyniidae from China. The genus is redefined based on this new species. Paraschizogynium plumachela sp. nov. can be separated from Paraschizogynium odontokeri Hunter & Rosario, 1987 by having an entire dorsal shield covering most of the dorsum, setae Z5 at least four times as long as setae s2, latigynal shields abutting each other anteriorly and each bearing two pairs of setae, a triangular mesogynal shield, two pairs of simple setae on integument of posterior margin of venter, three types of excrescences (one weakly sclerotized finger-like, one membranous feather-like and one coral-like) sub-distal on movable digit, deutosternal groove with four rows of fine denticles in female and three rows in male, and male hypostome dimorphic (hypostomal setae hp1 large, thumb-like, with one pair of seta-like spurs at base; hp2 tiny; hp3 hyaline, lobe-like).
