Diagnosis. This and the next species have three strong, transverse grey fasciae on
each ring, with a more even dispersion of finer striae set somewhat obliquely
over them. The hindwing tail and its black spot are symmetric as in Acropteris
Geyer, compared with the asymmetry in Strophidia Hübner and Pseudomicronia
Moore. M. aculeata is smaller than its Bornean congener and more
lightly marked, the striae appearing finer. The forewings, in the male at least,
are apically more acute. The striae are weaker in the forewing costal zone or
uniform with the rest, rather than more intense.
Taxonomic notes. The species is variable in the cream to grey tone of the ground colour,
strength and density of the striae. Occasional specimens have the underside
white rather than grey. The possibility of a species complex cannot entirely be
discounted, but no differences in the male genitalia could be detected in the
small number of specimens dissected representing extremes.
Geographical range. Oriental tropics east to Sulawesi.
Habitat preference. The species has not been recorded in recent surveys
but most old material is from lowland localities.
