Taxonomic and distributional notes: This species was originally described from the central Congo basin and is considered rare being known only from few specimens ( Broadley et al. 2003). Müller (1911) described Michellia katangae , from “Kituri, Katanga district,” Congo, and de Witte and Laurent (1947) considered it a subspecies of Hypoptophis wilsonii Boulenger, 1908 , which is currently viewed as a monotypic ( Wallach et al. 2014). Wallach et al. (2014) did not include Angola in the species distribution.
