Material examined. LAOS: Bolaven Plateau, Champasak Province, Paksong town , mountain tropical forest and pine plantations, 15°10'54"N, 106°14'25"E, 26– 28.07.2023, E. Spitsyna & V. Spitsyn leg. – 4♂ GoogleMaps .

Distribution in Laos. Champasak Province (this study).

Reference COI barcode sequences. GenBank acc. no. PV069499, PV069500.

Remarks. (1) The first record from Laos. Hence, the subspecies occurs in central Vietnam ( Quang Ngai Province) and southern Laos ( Champasak Province, Bolaven Plateau). (2) A. sinensis siriae represents a highly divergent lineage and has a COI p -distance of 1.9–2.9% from the nominate subspecies. (3) The description of this subspecies 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 external and genital morphology of the male specimens ( Figs 6C–D View Figure 6 , 18E–F View Figure 18 ). The redescription includes only those morphological features that are barely visible in the photographs.

Diagnosis. The subspecies can be distinguished from the nominate one by 7 fixed nucleotide substitutions in the COI gene fragment: 173C, 227T, 356G, 371A, 575T, 581A, 596C.

Brief redescription. Male morphology ( Fig. 6C–D View Figure 6 ): Wingspan 89–94 mm, forewing length 51– 58 mm (n = 4). Head light yellow or light creamy. Eye black. Antenna quadripectinate, light brown. Labial palp very short (its length ca. 0.25 of eye diameter), red-brown, with yellow apex. Thorax yellow, anteriorly reddish-brown and having sparse white scales. Patagium brown with sparse white scales. Tegula yellow, reddish-brown at base, with sparse white scales. Legs yellow, tarsus and tibia red-brown. Abdomen yellow, with unclear reddish spots laterally (spots may absent in some specimens).
