Acanthoscelides semiannulatus var. obscuricolor (Pic, 1929) . Combination confirmed.

Bruchus semiannulatus var. obscuricolor Pic, 1929a: p. 28 . From labels: “ Brazil. / Bahia / 1928 / In seeds of / Tiliaceae / Dr. G. Bondar” [Brazil]. Syntype female deposited in the MNHN. There is a “ Paratype ” label affixed to this specimen by J.M. Kingsolver as a paratype of Bruchus semiannulatus . However, the original publication does not designate a holotype nor does it indicate the number of specimens examined. Because no lectotype has been published, and because this synonymy was not intended by Pic (1929) in the original description, this must be considered a syntype.

Acanthoscelides semiannulatus var. obscuricolor: Blackwelder (1946), p. 761 (catalog, comb. nov.); Udayagiri & Wadhi (1989), p. 63 (catalog).
