Distribution in Laos. Sekong Province (this study).

Reference COI barcode sequences. GenBank acc. no. PV069510 ( Laos), PV069534 ( Thailand).

Remarks. (1) The first records from Laos and Thailand. Previously, the species was known only from its type locality (Kiriom National Park, Cambodia). (2) Antheraea angustomarginata Brechlin & Meister, 2009 seems to be a junior synonym of Antheraea gephyra Niepelt, 1926 , but its taxonomic status requires further studies. (3) BOLD contains the COI sequence of the holotype (sample ID SARBA362-08), it enabled our specimens to be accurately identified. (4) 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 Laos and Thailand, we present a brief redescription of the taxon, as well as illustrations of external and genital morphology of the male specimens ( Figs 10I–J View Figure 10 , 20G–H View Figure 20 ). The redescription includes only those morphological features that are barely visible in the photographs.

Brief redescription. Male morphology ( Fig. 10I–J View Figure 10 ): Wingspan 99–110 mm, forewing length 58–60 mm (n = 2). Head light brown, slightly covered with pink scales at base of antenna. Eye black-olive. Antenna quadripectinate, light brown. Labial palp short (its length ca. 0.5 of eye diameter), red-brown. Thorax orange-brown or light brown and having grey band anteriorly (overlapped by tegulae), pinkish ventrally. Patagium grey with intense white suffusion. Tegula pale yellow-orange or light brown, dark grey with intense white suffusion basally. Legs red-brown or light grey-brown with pink suffusion. Abdomen orange-brown, pinkish ventrally.
