HOLOTYPE: AMNH 162543, adult male, collected at Avakubi, 01.24N, 27.40E (Chapin, 1954a), Ituri district, Congo (Kinshasa), on 8 December 1909, by James P. Chapin (no. 511) on the Lang-Chapin Congo Expedition.
COMMENTS: In the original description, Traylor gave the AMNH number of the holotype and measurements for four male and two female specimens of avakubi. There were more than six specimens cataloged from this Chapin expedition and it is not clear which specimens in AMNH Traylor had examined.
