Taxonomic notes on the jalaurida -subgroup of the genus Lethe (Lepidoptera, Nymphalidae, Satyrinae)

In this paper, Lethe (Zophoessa) jalaurida (de Niceville, 1881) and its relatives, viz. the jalaurida-subgroup (sura-group), are studied. A new species, L. giancbi Lang Das sp. nov. which was identified as L. elwesi (Moore, 1892) by Lang Bozano (2015) and Lang (2017), is described from SE Tibet, China. Lethe elwesi houjiangae Lang Bozano, 2015 and L. jalaurida gelduba Fruhstorfer, 1911 are raised to specific status, viz. L. houjiangae stat. nov. and L. gelduba stat. nov. respectively. Lethe jalaurida plistia Fruhstorfer, 1911 is considered as an unnecessary replacement name of L. jalaurida gelduba. Lethe jalaurida nuolaensis Huang, 2001 is found to be a subspecies of L. gelduba stat. nov., viz. L. gelduba nuolaensis stat. nov.
