Scientific Name: Notogomphus maathaiae
Species Authority: (Clausnitzer & Dijkstra, 2005)
Taxonomic Notes: The taxon found on Mt. Elgon (Mau Escarpment) and in the collection of the Nairobi Museum as "N. lateralis" nomen nudum appeared in the 2006 IUCN Red List as Data Deficient. This taxon is now recognised as N. maathaiae.

Red List Category & Criteria: Endangered B2ab(iii) ver 3.1
Year Published: 2006

Justification:
This species was described from specimen found along the Rongai River, a clear, fast flowing montane stream in natural forests in the Mt. Elgon NP in about 2,000 m asl. Additional specimen were found in the Natural History Museum, London, which were collected in 1942 in the Katamayu Forest (central highlands of Kenya) and in the National Museums of Kenya, Nairobi, which were collected in 1970 in the Marioshoni Forest (East Mau Escarpment, Kenya). The records are from an altitude of about 2,200 to 2,600 m, suggesting that this is a truly montane species. Thus Notogomphus maathaiae depends on clear montane forest streams and is restricted to the forested montane areas in Kenya. Thus the area of occupancy is estimated to be less than 500 km². Montane forests have experienced serious losses during the past decades. It is assumed, that the species once was more widespread in the region, while it is now restricted to the remaining forest streams. As the forest destruction continuous due to a growing human population pressure, this species is likely to qualify for a higher ranking soon.
