Euonyx includes four species: E. chelatus Norman, 1867; E. coecus Pirlot, 1933 E . urania sp. nov. E . xarifa sp. nov. Incertae sedis . Euonyx conicurus K.H. Barnard, 1955 (genus uncertain); Diagnostic description. Antenna 1 peduncle article 1 without anterodistal lobe; accessory flagellum with an elongate article 1 (at least twice as long as article 2) partially covering callynophore. Antenna 2 without brush setae. Mandible molar a large, asetose flap or absent. Maxilla 1 outer plate with reduced seta-teeth in a modified 7/4 crown . Maxilla 2 inner plate subequal to or significantly shorter than outer plate. Gnathopod 1 chelate coxa 1 reduced, significantly shorter than coxa 2, tapering distally or subquadrate ischium long (length 2 × to 4 × breadth) too very long (length 4 × to 6 × breadth) carpus long (length 2 to 4 × breadth); propodus margins subparallel. Uropod 2 inner ramus not constricted. Telson deeply cleft. Remarks. Euonyx appears to be the immediate sister taxon of Stephonyx Lowry & Stoddart, 1989. Euonyx has abandoned the scavenging life-style to become an ectoparasite of echinoids and in the process developed severely reduced mouthparts, particularly the seta-teeth of the maxilla 1 outer plate. In Euonyx coecus Pirlot, 1933 the setal-teeth of maxilla 1 appear to be intermediate between Euonyx and Stephonyx , but the mandibular molar is absent, an important characteristic of Euonyx .
