Material examined. CHINA, Fujian: Jian’ou, Wanmulin, VIII.1988, coll. Shen Shuigen, 132Ƥ (Holotype, Allotype and 1 Paratype) (SIECAS).

Diagnosis. The wing shape of N. brunhyala is similar to that of Strepsigonia robusta Holloway, 1998 (Borneo, Sumatra, Peninsular Malaysia) in the following characters: the forewing apex is distinctly falcate, and the outer margin under the apex is straight in the male, and slightly expanded in the female; a shallow excavation is present on the tornal angle; the apex of the hind wing is notched. The wing pattern has similar transparent patches to those found in Spectroreta . We place the species in the genus Amphitorna in recognition of the similar socii, gnathos, and the bilobed signum. The valva is broad and blunt at apex, and bears a hooked basal process; the sacculus is well developed, and tapering; the saccus is distinct from those of other species of Amphitorna , being well developed, and the aedeagus has a developed cornutus. Sternite 8 is protruding and well sclerotized medially. The female genitalia have a large bilobed signum in the corpus bursae.

Distribution. China (Fujian, Guangdong).

Remarks. As montioned above, the name Cyclura Warren, 1897 is a junior homonym of Cyclura Harlan, 1825 (Reptilia) , and is replaced by Neoreta . Against this background we combine brunhyala , which was described in Cyclura , with Neoreta correspondingly. However, brunhyala has very different valvae and saccus shapes from species of Neoreta , though they have a similar uncus, socii and pair of median processes of the gnathos. The saccus of brunhyala is strongly convex, while three species of Neoreta ( N. olga , N. perexcisa and N. purpureofascia ) have the saccus concave: according to Watson (1967), the rest have a convex saccus; we have examined this in N. excisa and N. submontana , and find that in both cases it is only slightly convex. While recognising these differences we leave brunhyala in Neoreta for the present, since it does not seem to fit any other presently established genus, but this point may need revisiting in the future.
