Alidus signatus Pic, 1926 is transferred from Mispila to Souvanna, and Souvanna signata (Pic, 1926), comb. nov. is proposed. The lectotype of Alidus signatus is designated. The following synonyms are proposed: Souvanna signata = Athylia (s. str.) quadristigma (Gressitt, 1940), syn. nov. = Souvanna phoumai Breuning, 1963, syn. nov. = Mispila (Dryusa) coomani Breuning, 1968, syn. nov., Mispila (s. str.) tenuevittata (Pic, 1930) = Mispila (s. str.) assamensis Breuning, 1938, syn. nov. The gender of the holotype of Alidus multilineatus Pic, 1925 is determined. New distributional records for Souvanna signata, Mispila curvilinea Pascoe, 1869, M. subtonkinea Breuning, 1968 and M. tenuevittata are provided.
Gender definition, lectotype designation, new combination, new faunistic records, synonyms
During the study of the genera Souvanna, Athylia, and Mispila, we found that the taxonomic status of Athylia quadristigma, Souvanna phoumai, Mispila coomani, and Mispila assamensis were doubtful; additionally, the gender of the holotype of Alidus multilineatus Pic, 1925 (currently, a junior synonym of Mispila curvilinea Pascoe, 1869) was unknown. Therefore, we studied these issues and report our results here.
Specimens examined are deposited in following institutions and private collections:
CSG Collection Andre Skale, Gera, Germany;
CWW Collection Andreas Weigel, Wernburg, Germany;
LPSNU School of Biological Science and Technology, Liupanshui Normal University, Liupanshui, Guizhou, China;

6.5–10.7 mm (♂), 9.6 mm (♀). The gender of the types of Alidus signatus (lectotype), Souvanna phoumai (syntype), and Mispila coomani (holotype) were unknown, so the body length was determined from the types of Enispia quadristigma and additional materials examined.

Athylia and Souvanna belong to the tribe Apomecynini, while Mispila belongs to the tribe Pteropliini. According to the key to tribes of Lamiinae and the key to genera of Apomecynini (
After our examination of these materials, we can confirm that this species belongs to the tribe Apomecynini, and, according to the mentioned features, it belongs to the monotypical genus Souvanna.
