This key is the English translation of the key Wang & Chiang (2000) proposed.
Here you can find the original key (China mud color longicorn genus Uraecha Thomson Classification of (Coleoptera: CERAMBYCIDAE: Lamiinae) - Entomotaxonomia 22 (1): 45-47).



1. Elytral apex spined externally: South Korea, Taiwan, Japan .........U. bimaculata Thomson, 1864*
Holotype here



-. Elytral apex not spined externally.........................................................................2



* Here U. guerryi (PIc, 1903) from Yunnan (Holotype here)

and U. oshimana Breuning, 1954 from RyuKyu (Oshima I.), both with shorter apical spines

Bon, content que notre Forum a aidé a clarifier ce genre.
Je vais modifier la clé.
Il y a aussi une espèce à adjoindre...

Dans cet article les synonymies suivantes sont proposées:

Uraecha longzhouensis Wang & Chiang, 2000 syn. nov. = Annamanum lunulatum (Pic, 1934); ce qui est bien indiqué dans la clef .

Uraecha perplexa Gressitt, 1942 syn. nov. = Uraecha yunnana Breuning, 1936. A modifier donc dans la clef.

Ok. I have modified "a bit" the key.

If you have a series specimens about same species, you will find the elytral markings variational in a range (like in U. angusta and U. obliquefasciata )
That's why the Key was somewhat difficult to use.

In addition,
Uraecha longzhouens Wang & Chiang should be considered a synonym of Annamanum lunulatum Pic.
For the authors ignored the character of mesosternal process tuberculate or not, in the original description, and the other characters fit A. lunulatum well.
Of course, it's need to check the type for further conclusion.
