Amended key to Antatelson species: 1. Body dorsally smooth.2 – Body dorsally not smooth.4 2. Gnathopod 2 carpus elongate, longer than broad. A. cuneatum Krapp-Schickel, 2006 – Gnathopod 2 carpus length subequal to width.3 3. Uropod 1 longer ramus much shorter than peduncle; gnathopods with parallel margins. A. antennatum Bellan-Santini & Ledoyer, 1973 – Uropod 1 longer ramus subequal to peduncle; gnathopods distally widened.[Thaumatelson herdmani Walker, 1906] 4. Head with rostrum, body without tubercles or processes, but keeled. A. rostratum Bellan-Santini & Ledoyer, 1973 – Head without rostrum, body with tubercles or processes.5 5. Peraeon and pleon segments with dorsal tubercles. A. claudei sp. nov. – Only pleon with tubercles, peraeon smooth.6 6. Pleon segments 1-3 with tubercles. A. tuberculatum Andres, 1989 – Pleon segment 1, 2 smooth, third segment with acute nasiform process, (one upright tubercle), without accompanying small processes. A. walkeri (Chilton, 1912) probably syn. to A. cultricauda (K.H. Barnard, 1932) with accompanying small process.
