Males develop a distinctive nuchal hump with pearl organs during the breeding season. This sexual ornament is uniquely divided in two by a notch at the level of the eyes, from which the generic name Incisilabeo is derived: {{lang|la|incisum}} "notch" plus Labeo.{{cite web | url = https://etyfish.org/labeoninae/ |title = Family CYPRINIDAE: Subfamily LABEONINAE Bleeker 1859 (Labeos) | access-date= 25 April 2024 | author1 = Christopher Scharpf | author2 = Kenneth J.
