Measurements. Male: BL: 14.8–18.4 mm, FL: 8.78–9.22 mm.

The species is widely distributed in South China, and its detailed distributional information will be listed in a forthcoming paper by Qing-Hao Zhao. In general appearance, the species is similar to P. plagiicollis (Fairmaire, 1891) which overlaps in distribution. Yet, P. marmorellus can be easily distinguished from the latter by bearing pale appressed microsetae on the forebody, which are absent in P. plagiicollis. Distribution. China (Hainan), Myanmar, Vietnam, Indonesia. New to China.
