The type specimens and other specimens are deposited in the following institutions whose names are abbreviated in the text as follows:
Small-sized issids. Vertex pentagonal, anterior margin obtuse-angled convex, posterior angulately excavate, marginal carinae straight. Pronotum as long as vertex, with small pit between median carina and lateral carina. Mesonotum shorter than vertex and pronotum together, with median cargin obscure. Forewings oval, with claval suture absent or obscure, M simple. Hind wings incised on the margin into two lobes, anal lobe absent or excessively reduced, veins simple. Fore- and mesofemora flattened; hind tibia with a small sub-basal spine and two distinct lateral spines.

The new species is named for the memory of R.G. Fennah, who established the genus
China (Yunnan).
This species can be distinguished from other congeners by the dark oval patch on the forewings (Fig.
