(Fig. 36)

Notosacantha sinica Gressitt, 1952: 449.

Type locality. China, Fujian Prov., Shaowu Co., Dazhulan, approx. 27°41.7′N, 117°39.0′E, 1000 m a.s.l.

Original type series. Described only from the holotype (LMNH).

Type material examined. Holotype, glued: ‘Fukien, S. China | ShaoWu TaChuFung [hw] | IV-25–30 - [hw]19[p]43[hw] T.C.Maa [w, p, cb] || L-113 [w, t, cb] || HOLOTYPE | NOTOSACAN [hw] | THA SINICA [hw] | J.L.Gressitt [r, p + hw by Gressitt, cb] || 529 [w, hw, cb] || En-289736 | [Data Matrix barcode] SYS [w. p, cb]’.

Current status. Valid species.

Remarks. Gressitt (1950) stated that the specimen came from ‘Ta-chu-lan’ but on the label is ‘TaChuFung’, however both names refer to the same place known as Dazhulan.

Notosacantha sinica belongs to the N. vicaria group and runs to the thesis 100 of the Spaethʼs (1933) key. Recently, several other species were added to the group: N. banaszkiewiczae Świętojańska & Stach, 2011, N. dembickyi Sekerka, 2008, N. kantneri Świętojańska & Borowiec, 1999, and N. nigrodorsata Chen & Zia, 1961. Notosacantha sinica is particularly similar to N. nigrodorsata as both species have black dorsum with yellow spot in the middle of the explanate margin of elytra. According to the original description and key provided by Chen et al. (1986) N. sinica differs in antennae with black club, mostly black ventrites, and apical tubercle with sutural branch while N. nigrodorsata has ventrites including antennae brown and apical tubercle without sutural branch. According to the colour figure in Chen et al. (1986) N. nigrodorsata has more elevated costae, is less parallelsided, and has explanate margin broadly yellow thus without distinct yellow sutural spot present in N. sinica.
