Fig. 1. Collecting area in Laos (20°12’N, 104°01’E) (marked with a black dot).
Fig. 2. Rooted maximum likelihood tree with information about morphospecies assignments, results of species delimitations (bPTP, mPTP, TCS, ABGD, BOLD, and BINs) and photographs of the aedeagi (lateral view). Green boxes indicate agreement between molecular species delimitation method and morphospecies assignment, while red boxes indicate disagreement. Ultra fast bootstrap supports >0.5 is shown above nodes. Genus name abbreviations: Chr. -Chrysoserica , G. - Gastroserica , Ma. - Maladera , Mi. - Microserica , N. - Neoserica , L. -Lasioserica , S. - Serica .
Fig. 3. Split network of all examined specimens. Singletons are highlighted in blue squares, others in orange colours. Morphospecies nested within others are highlighted with red squares or circles around them.
