Remarks. Notosacantha oblongopunctata is at first glance most similar to N. siamensis (Spaeth, 1933) with nearly identical constitution of dorsal costae and falls next to it in Spaethʼs (1933) key. It differs by elytral costae more elevated, stout and almost rectangular body (distinctly longer than wide in N. siamensis), and distinctly coarser pores, particularly those on inner half of the explanate margin of the elytra.
