Down Cat-eLog Data Sheet
Scientific Name Pseudolithoxus kinja  Bifi, de Oliveira, Rapp Py-Daniel & Collins, 2018
Common Names L385, Green Flyer Pleco
L492, Grøn Flyversugemalle (Denmark)
Type Locality Rio Uatumã, Santa Luzia de Jacarequara, São Sebastião do Uatumã, Amazonas, Brazil, 02°26'46.7"S, 58°16'31.9"W.
Pronunciation sue doh lith ox uss.

The Kinja people inhabit areas surrounding the rio Uatuma and part of the rio Negro in the states of Amazonas and Roraima, Brazil.
Down Species Information
Size 171mm or 6.7" SL. Find near, nearer or same sized spp.
Identification Pseudolithoxus kinja is diagnosed from all congeners by having a colour pattern of large pale spots on a dark background (vs. pale bands on a dark background in P. kelsorum and P. tigris; small pale dots on a dark background in P. anthrax and P. nicoi; dark spots on a lighter background in P. dumus). Furthermore, P. kinja can be diagnosed from P. anthrax and P. nicoi by having dark bands on the caudal fin (vs. absence).
Sexing Young specimens and fully reproductive males have a urogenital papilla which is well-developed as a small elongate tube located immediately behind the anal opening. This small tube is almost perpendicular to the main plane of the body, facing ventrally with a tiny opening at the tip. The condition in females is similar to that found in other hypostomines. In mature males with developed testes, the third branched pelvic-fin ray becomes elongated, and the whole fin becomes lanceolate. In the anal fin of mature males, the second simple ray becomes almost twice the length of the first short ray, and the first, second, and third branched rays also become elongate (the third the longest); owing to this fin-ray elongation in mature males, the whole anal fin becomes larger and has a strongly curved posterior border rather than the regular straight border usually seen in females or non-reproductive males.
General Remarks L385 was first reported from the rio Trombetas. L492 was first reported from the rio Jauaperi.
