Antheraea angustomarginata Brechlin & Meister, 2009 Figs 10I–J, 20G–H Material examined. LAOS: Sekong Province, Lamam town, dry monsoon forest, 15°21'39"N, 106°42'45"E, 25– 27.12.2022, E. Spitsyna & V. Spitsyn leg. – 1♂. THAILAND: Loei Province, dry mountain monsoon forest with bamboo patches, 17°06'18"N, 101°37'09"E, 08– 09.04.2014, V. Spitsyn & I. Bolotov leg. – 1♂. 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, 20G–H). The redescription includes only those morphological features that are barely visible in the photographs. Brief redescription.
