Diagnostic description. Head lateral cephalic lobe large, narrowly rounded; ventral margin curved. Antenna 1 peduncular article 1 without posterodistal spine; accessory flagellum 2-articulate, article 1 short; flagellum without callynophore in female, [male not known]. Mandible lacinia mobilis a simple robust seta; lamina dentata absent; accessory setal row present, not on raised setose ridge; molar absent; palp attached slightly distally; palp article 2

broad, shorter than article 3; not distally tapered, with anterior margin convex. Maxilla 1 outer plate with 9 setalteeth in 5/4 arrangement, outer row setal-teeth with medial cusps; palp well developed, 2-articulate, with apical slender setae. Maxilliped inner plate small; outer plate large; palp 4-articulate, article 4 large. Gnathopod 1 chelate; ischium smaller than propodus, not swollen posteroproximally; carpus extremely compressed; propodus length about 1.8 × breadth, posterior margin well developed, posterodistal corner of palm attenuated, corner of palm with simple robust seta; dactylus over-reaching palm. Gnathopod 2 palm large, transverse. Pereonite 4 without dorsal spines. Pereonite 5 without dorsal spines. Pereopod 5 merus without posteroproximal shoulder. Pereopod 6 basis with posteroventral lobe produced beyond ischium; merus longer than broad, with broadly rounded posteroproximal shoulder. Pereopod 7 basis subovate with posterior margin smooth. Oostegites from gnathopod 2 to pereopod 5. Epimeron 3 posterior margin without projections, posteroventral corner broadly rounded. Uropod 3 biramous, inner ramus just reaching base of article 2 of outer ramus. Telson   as long as broad, entire.

Remarks. Figorella corindon   , F. macrophoculata   and F. tasmanica   all have a large gnathopod 2 palm and F. corindon   and F. tasmanica   both have a short mandibular palp article 2. Figorella corindon   is distinguished from F. tasmanica   by the number of setal-teeth on maxilla 1 outer plate, the length of gnathopod 1 dactylus and the shape of the gnathopod 2 palm.
