Modified from Bamber & Chatterjee (2010) . Female . Paratanaidin, with eyes present. Pereonites all shorter than broad. Pleonites 1–4 epimera with simple seta and thick circumplumose seta. Antennule of three longer articles with or without minute distal article, article-1 with incomplete division, distal article with eccentric distal tip (apical spur). Antenna article-2 without ventral expansion or distal seta-bearing apophyses. Mandible left molar apex cleft or uncleft. Maxillule endite with nine terminal spines (some hooked). Maxilliped endites with round or incisor-shaped distal tubercles. Cheliped palm with slender distolateral spine adjacent to fixed finger; dactylus with or without slender ventral spines. Pereopod-1 basis with or without superior seta. Pereopods 2–3 carpus inferodistal crotchets molariform or longer than broad, unequal. Pereopods 4–6 coxa simple; merus with one or two inferodistal crotchets (one molariform in T. meios ); carpus with paired inferior spinulate ridges, one superodistal seta and two or four distal crotchets, one molariform. Uropod peduncle shorter than endopod; endopod two-segmented; exopod one-segmented, shorter than segment-1 of endopod. Male. Unknown. Remarks . Although with an extensive diagnosis, the defining character of Triparatanais is the partiallydivided antennule article-1 (see also Bamber & Chatterjee 2010 : 22), unlike the fully-fused article of Periparatanais . Useful features are the relatively short cheliped fixed finger/dactylus in relation to the palm and presence of molariform crotchets on the merus ( T. meios Bamber & Chatterjee, 2010 ) and carpus of pereopods 4–6.
