Aspidostemon microphyllum   is similar to A. andohahelense   . The two can be separated as follows: A. microphyllum   has stiffer, smaller leaves (4-6.5 cm in A. microphyllum   , 6-9 cm in A. andohahelense   ), and conspicuous (vs. very inconspicuous) locelli. Their distribution is also quite different, A. microphyllum   only known from a small island in the Bay of Antongil and the Masoala Peninsula in the NE ( Fig. 15 View FIG ) and A. andohahelense   only known from the Col de Maningotry and Andohahela in the SE. Aspidostemon microphyllum   is only known from two collections. No vernacular name has been recorded.
