- <p><b><i>PARALITHOXUS</i> BOESEMAN, 1982: 46.</b></p><p><i>Type species:</i> <i>Ancistrus bovallii</i> Regan, 1906: 96.</p><p><i>Diagnosis: Paralithoxus</i> can be diagnosed from other members of Lithoxini by having at most low hemispherical papillae around the oral disc margin (Fig. 1; vs. digitate papillae in <i>Exastilithoxus</i>), 14 (rarely 13) branched caudal-fin rays (vs. 12 in <i>Avalithoxus</i>), five branched anal-fin rays (vs. four in <i>Avalithoxus</i> and <i>Lithoxus</i>), seven to nine interdorsal plates (vs. five in <i>Avalithoxus</i> and <i>Lithoxus</i>), and five rows of plates on the caudal peduncle (vs. three in <i>Avalithoxus</i> and <i>Lithoxus</i>). <i>Etymology:</i> Boeseman (1982) did not provide an etymology for <i>Paralithoxus</i>, but it can be assumed that the original Greek meaning of the prefix <i>para</i> - (i.e. beside; next to, near, from; against, contrary to) was intended to distinguish this clade from <i>Lithoxus</i> while still alluding to their close relationship.</p>
