Distribution in Laos. Champasak Province (this study). Reference COI barcode sequences. GenBank acc. no. PV069503, PV069506. Remarks. (1) The first record from Laos. (2) BOLD contains the COI sequence of the holotype (sample ID SARBB1064-09). (3) The description of this species was published in a non-open access journal offering only a print edition which is not available for purchase. Therefore, based on the specimens collected from Bolaven Plateau, we present a brief redescription of the taxon, as well as illustrations of the adults of both sexes and the male genitalia (Figs 8E–F, 19H). The redescription includes only those morphological features that are barely visible in the photographs. Brief redescription.
