Diagnosis

Distinguished from all other species of Gymnochanda by the following characters: mature males have pinkish body with dorsal half suffused with reddish pigments, anal and second dorsal fins expanded with their soft rays also expanded to reach 2/3 of caudal fin forming a crescentic profile, without any individual fin ray free from the interradial fin membrane; anterior part to whole of both anal and second dorsal fins maroon red in life, with posterior portion of distal rays black forming a crescentic pattern (hyaline when preserved); caudal fin entirely lightly suffused with red in life (hyaline when preserved); females possess yellowish body suffused with reddish pigments without any fin elongation (hyaline when preserved), both dorsal fins suffused with reddish pigments (hyaline when preserved) (Ref. 97398).
