Maringma-tepui, also written Mount Maringma and historically known as Mount Marima,Maguire, B. (March 1948). Plant explorations in Guiana in 1944, chiefly to the Tafelberg and the Kaieteur Plateau—II. Bulletin of the Torrey Botanical Club 75(2): 189–230. {{JSTOR|2485397}} is a small tepui of the Pacaraima Mountains in Cuyuni-Mazaruni, Guyana. It is known as Malaima-tepui in the local Akawaio language. Most published sources place it just inside Guyanese territory, very close to the border with Brazil, and around {{convert|17|km|mi}} east of Roraima-tepui.[http://botany.si.edu/bdg/mainmap.cfm?lastname=Clarke BDG Plant Collectors: David Clarke].

The village of Wayalayeng lies at the base of Maringma-tepui and it is from here that the mountain was explored in May–July 2004 by a botanical team of the Smithsonian Institution. Led by David Clarke, this was the first expedition to reach the mountain's summit. It was followed by two further expeditions in February 2006 and late 2007, by Bruce Means and Philippe J. R. Kok et al., respectively.

Maringma-tepui has a maximum elevation of around {{convert|2147|m|ft|abbr=on}} or {{convert|2134|m|ft|abbr=on}}.Kelloff, C.L., S.N. Alexander, V.A. Funk & H.D. Clarke (2011).

David Clarke.] Smithsonian Contributions to Botany 97: i–viii, 1–307. The summit plateau has an area of roughly {{convert|170|ha}} and is highly uneven, allowing water to collect in many deep, swamp-like pools. It is predominantly covered in low-growing "tepui meadow" vegetation, quaking peat bog, and some dwarf forests of Bonnetia roraimae, with few areas of exposed rock. The dominant plant families include Bonnetiaceae, Bromeliaceae, Clusiaceae, Orchidaceae, Rapateaceae, Sarraceniaceae, and Xyridaceae. Temperatures vary widely on the summit plateau, with extremes of 13.5 and 37.5 °C recorded over a five-day period.

Native herpetofauna include the lizard species Arthrosaura hoogmoedi and Pantepuisaurus rodriguesi (Gymnophthalmidae), as well as the frog species Adelophryne patamona (Eleutherodactylidae);Fouquet, A., D.
