Etymology: Cryptomyrus: Name from the Greek ‘kryptos’ for secret or hidden, referring to the rarity of these fishes in collections and the Greek ‘myros’ for a kind of fish, a suffix used in the names of many other mormyrid genera.; ogoouensis: The specific epithet is a Latinized noun in the genitive case and refers to the Ogooué River of Gabon (Ref. 113668).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 6.9 - 6.9. Tropical; 27°C - ? (Ref. 113668)
Africa: Ogowe River at Doumé Falls in Gabon (Ref. 113668).

Morphology | Morphometrics
soft rays: 31;
Vertebrae: 43. Diagnosis: Cryptomyrus ogoouensis is readily differentiated from its sole congener, C. ona, by the following characteristics: the possession of an anal-fin origin located well in advance of the dorsal fin, first dorsal ray above anal-fin ray 7 vs. first dorsal ray above anal-fin ray 3; a narrow caudal peduncle, its depth 5.1% of standard length vs. 6.0-6.8%; and lobes of caudal fin nearly as long as caudal peduncle, vs. markedly shorter (Ref. 113668).
