Abstract
A new species of the Lethe trimacula-group, viz. L. langsongyuni sp. nov. is described from Weixi County, representing the third member of this species group in northwestern part of Yunnan Province, southwestern China. In general L. langsongyuni sp. nov. is closely related to L. liae Huang, 2002, L. proxima Leech, 1892 and L. umedai albofasciata Huang, 2002, but it can be distinguished from all of them by combination of several details in wing pattern and male genitalia. The adults and male genitalia of the species aforementioned are illustrated.
