Known from the middle Congo River basin, just upstream of Pool Malebo (Ref. 104438). In 2011, when water levels in the main channel of the middle Congo River reached an historic low, a series of rocky outcrops, that in previous (and subsequent) years had been completely submerged, were partially exposed and accessible for sampling and it was only on these that specimens of Teleogramma obamaorum were collected; since only very few rocky outcrops were located, and most of the shoreline was comprised of sandy or reed-fringed banks, this suggests that the short stretch where all T. obamaorum specimens were collected may represent the entire distributional range of the species (Ref. 104438). Type locality of the holotype of Teleogramma obamaorum: 'Democratic Republic of Congo, Kinshasa Province, main channel of middle Congo River at rocky outcrop en route to Mayi Ndombe River' (Ref. 104438).
