Abs ac
In his a icle, we desc ibe Radhica us juzhanini sp. no ., a new c yp ic species om sou he n Laos and Vie nam. The
new species is a sis e species o Radhica elisabe hae de Lajonquiè e, 1977 which was desc ibed om Suma a. The
sequences o his species a e a he dis an om opo ypes o R. elisabe hae om Suma a (unco ec ed COI p-dis ance
> 8%). The new species is dedica ed o Pe Y. Us juzhanin, a specialis in P e opho idae and Aluci idae.
Key wo ds: new species, axonomy, biodi e si y, DNA ba coding, c yp ic species, Annamese Moun ains.
In oduc ion
The genus Radhica Moo e, 1879 con ains six species dis ibu ed om China and India o Ja a and he
