This species is known only from the Tana River area in Kenya
This species is just known from a single specimens collected more than 100 years ago and are most likley extinct today.

If Boulengerula denhardti is identical with Schistometopum gregorii this species is still alive!

Schistometopum gregorii Red List Category & Criteria LC ver 3.1 (2001) Year Assessed 2004 Assessor/s Loader, S., Howell, K., Gower, D., Measey, J. & Wilkinson, M. Evaluator/s Stuart, S., Chanson, J. & Cox, N. (Global Amphibian Assessment Coordinating Team) Justification Listed as Least Concern because, although it is seldom recorded, it has a relatively wide distribution, is probably not dependent on threatened habitats, has a presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. www.redlist.org/search/details.php?species=59591

Rediscovery of Boulengerula denhardti Nieden 1912 (Amphibia: Gymnophiona: Caeciliidae) in Meru County, KenyaThe dearth of information on caecilian amphibians is most likely due to a lack of directed field studies. Here we report the rediscovery of a population of Boulengerula denhardti nearly a century after its description by Nieden in 1912. Morphological examination of seven specimens suggests that they are closer to the type of B. denhardti than to any other member of the genus. Nieden's type locality has been widely interpreted as the Tana River Delta, although searches there have not revealed specimens of this species. The locality of the material described herein comes from Ngaia Forest, Meru County, Kenya, approximately 420 km, northwest of the Tana Delta. We discuss dispersal in caecilians and their likely use of riverine corridors. We speculate that more species in this genus are likely to be found in Kenya. www.bioone.org/doi/abs/10.3377/004.047.0118

Moved back to extinct amphibians, as the previously reported rediscovery is erroneous, based upon specimens belonging to a new species and not B. denhardti.

According to Malonza & Bwong (2023) it is endemic to the lower Tana River (i.e., around Witu) with two recent records (2016) from a degraded forest patch at Lake Kenyatta, and on farms adjacent to this forest. There is a photograph of a live individual from Lake Kenyatta in the book. They agree that the specimens collected from the Ngaia Forest Reserve between 2007 and 2013 belongs to B. spawlsi.
