Etymology: Pseudocrossocheilus: Greek, pseudes = false + Greek, krossoi = tassel + Greek, cheilos = lip; papillolabrus: From the Latin Papillo meaning papilla and labra meaning lip, in reference to its densely covered papillae on the lower lip and the width of the papillate area being larger than other species of Sinocrossocheilus (Ref. 50421).
