Yan, Cheng-Jin, Achterberg, Cornelis Van, He, Jun-Hua & Chen, Xue-Xin, 2017, Review of the tribe Helconini Foerster s. s. from China, with the description of 18 new species, Zootaxa 4291 (3), pp. 401-457 : 419

Wroughtonia alba ( Chou et Hsu, 1998) , comb. nov.

Helcon albus Chou et Hsu, 1998: 295 –296.

Comparative diagnosis. Similar to W. zhejiangensis , but W. alba has vein 1r-m of hind wing about as long as vein 1-M, the ventral protuberance of the hind femur wide (narrow in W. zhejiangensis ), the precoxal sulcus shallow and without rugae (distinctly impressed and with rugae) and the hind coxa is reticulate dorsally (sparsely punctulate).

Host. Unknown.

Distribution. China ( Taiwan).

Notes. Helcon albus Chou et Hsu from Taiwan is included in Wroughtonia , because it has a wide obtuse ventral protuberance on the hind femur, the hind tarsus is pale and the antenna has a white band. The species is included provisionally in the key on basis of the original description, because the holotype (and only known specimen of W. alba ) was not available for examination. Spasskia anastasiae Belokobylskij from Far East Russia is included in Wroughtonia (as other Spasskia spp.) but is not close to the other species because of the obtuse ventral protuberance of the hind femur and the shape of the first tergite and of the occipital carina. In the key it will come near W. alba because the hind coxa are densely sculptured (transversely rugulose to rugose) dorsally; differs from W. alba by the complete dark brown or black antenna (with white band in W. alba ), palpi dark brown basally (brownish yellow), temple and vertex densely and coarsely punctate-rugose (smooth) and hind coxa dark brown or black (brownish yellow).
