Type species. Grynaminna tamakii Poore, 2000 , by original designation and monotypy.

Diagnosis. Anterior branchiostegal lobe sclerotised, well produced anteriorly beyond junction with oblique branchiostegal ridge with which it articulates by means of a virtual condyle. Rostrum obsolete or obtusely triangular, flat, not reaching cornea. Pleomere 1 tergite undivided or with weak transverse ridge. Antennular peduncle length more than 3 times the width of both eyestalks, longer than antennal peduncle. Maxilliped 3 ischium and merus narrow, more than twice as long as wide at their articulation; crista dentata consisting of a row of numerous denticles; propodus about as wide as long, free distal margin transverse or nearly so. Male major cheliped merus with convex tuberculate blade on most of lower margin. Male minor cheliped much narrower than major, carpus longer than palm, fingers shorter than palm. Pereopod 3 propodus subpentagonal, with strong broadly rounded proximal lobe on lower margin, lower margin straight-concave. Pereopod 4 propodus minutely chelate, fixed finger as long as dactylus. Male pleopod 1 consisting of 2 articles, article 2 ovoid, with shallow apical notch between rounded subdistal lobe and curved acute apex. Male pleopod 2 appendix interna free, articulating, distal on mesial endopod margin (fig. 15m). Pleopods 3–5 appendices internae barely emerging from endopodal margin. Uropodal endopod with convex anterior margin, acute-rounded apex, straight-slightly curved posterior margin, longer than wide. Telson converging to about half basal width from near anterior width over most of length to rounded posterolateral corners, posterior margin straight or convex between tapering posterolateral margins.

Remarks. Only one Recent species is known. The antennular peduncle is particularly long, the rostrum particularly short and the merus of the major cheliped has a convex tuberculate blade along most of its lower margin.
