Relevant Information:

Description: Cambeva intermedia is distinguished from all other congeners of CBC by having seven pectoral-fin rays (vs. six) and a subtrapezoidal autopalatine (Figure 3L; vs. subrectangular). Cambeva intermedia is distinguished from all other congeners of CBC, except C. insperata, by having the distance between the posterior nostril and the orbital rim about two times the distance between the anterior and posterior nostrils (vs. about equal). Cambeva intermedia is distinguished from C. insperata by having incisiform jaw teeth arranged in two or three regular rows (vs. jaw teeth sub-incisiform, with rounded extremity, irregularly arranged); 36–38 vertebrae (vs. 39–41); and the presence of pelvic fin (vs. absence). Habitat: Stream at about 465 m asl, with small pebbles and gravel on the bottom. Specimens were found below small pebbles and gravel. Etymology: The genus name Cambeva: vernacular name for trichomycterids in southern and southeastern Brazil, derived from the Tupi a’kãg, head, and pewa, flat, referring dorsally flattened head. The specific name intermedia: From the Latin intermedia (intermediate), due to morphological features that are intermediate between those typical of specialised fossorial and unspecialised species.
