Poore, Gary, 2009, Leipanthura casuarina, new genus and species of anthurid isopod from Australian coral reefs without a " five-petalled " tail (Isopoda, Cymothoida, Anthuroidea), ZooKeys 18 (18), pp. 171-180 : 172

Anthuridae Leach, 1814

Diagnosis. Body 10–15 times as long as wide, non-males occasionally more elongate; pereonite 7 wider than long, much shorter than pereonite 6. Pleonites 1–5 together not more than twice as long as wide, fused; without marginal plumose setae on pleonal epimera or posterior borders of pleonites 4 and 5. Antenna 2 flagellum of fewer than 10 articles, shorter than peduncle. Mouthparts not produced anteriorly. Mandible compact and with weakly-toothed transverse incisor. Maxillipedal endite reaching palp article 3, or absent or obsolete; palp broad (c. twice as long as wide), with 5 free articles or with 2 or more articles fused. Pereopods 2 and 3 carpus not or weakly produced distally on lower margin; propodus palm with 1 distal robust seta only. Pereopods 4–7 propodus palm with 1 distal robust seta. Pereopod 7, if present, having propodus without distal serrate setae. Pleopod 1 exopod operculiform alone. Statocysts paired.

Remarks. This family diagnosis is slightly modified from that of Poore (2001) who adjusted earlier concepts, e.g., of Wägele (1981), by removing some genera to Expanathuridae Poore, 2001 . The significant change in this new diagnosis is to accommodate the absence of pereopod 7.
