Remarks. Yang et al (1995) described the monotypic genus Manusciara based on the type species M. quadridigitata Yang, Zhang & Yang, 1995 from Mt. Baishanzu, Qingyuan, Zhejiang province, China. The characteristics of this genus was provided as follows: male eyes with interfacetal hairs, 4th flagellomere longer than wide, maxillary palp three segmented, tibial spurs 1:2:2, foretibial comb 1-rowed, veins C, R, R1, Rs and r-m with macrotrichia; distimere of genitlia with a long arm-like process. The authors considered the arm-like process, which is called dorsal lobe on the gonostylus in Prosciara , as an unique characteristic of Manusciara and therefore named after it. Moreover, all the other diagnostic traits of Manusciara are also common in Prosciara and the type species M. quadridigitata shows all the characters as a Prosciara member. Therefore, we treat Manusciara as a synonym of Prosciara . Additionally, by sharing the very similar form of the gonostylus and its dorsal lobe, and also the arrangement of the megasetae, the species resembles P. tetracantha sp. nov. ( Fig. 22 B). For their differential diagnosis, see under P. sinensis sp. nov.
