Diagnosis. The wing pattern of Statherotis amaeboea (Figs. 1–2) is similar to S. discana, S. leucaspis and S. muangmaithongi sp. nov. by having a subtriangular patch on the costa. It can be distinguished by the subrectangular shape of the hindwing rather than the subtriangular shape in the three latter species. The male hind tibia (Fig. 18) has the tuft of pale yellow hair pencils larger than in the other species. Abdominal terga 6–8 of males have three pairs of dense, long modified scales (Fig. 24). Male genitalia (Fig. 29) are superficially similar to S. olenarcha, but the bilobed uncus is broader than the latter species. Female genitalia (Fig. 34) have an aciculate ringed ridge surrounding the ostium bursae (Fig. 36), but lack pendant lobes laterally. The signa have widened patches of dense teeth (Fig. 38) that are quite larger than those in S. muangmaithongi sp. nov.

Remarks. Specimens from Thailand were collected from dry evergreen forest, grassland, and a restoration forest in an old Para rubber tree plantation at a wide range of elevations, 46– 786 m.
