Type species. Callianassa trilobata Biffar, 1970 , 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. Maxilliped 3 ischium and merus less than twice as long as wide at their articulation; propodus about as wide as long, free distal margin transverse or nearly so; exopod present. Male major cheliped merus lower margin convex or blade like, especially proximally, with small denticles. 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 or weakly convex. Pereopod 4 subchelate. 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 absent or reduced to obsolete distomesial lobe. Pleopods 3–5 appendices internae barely emerging from endopod margin. Uropodal endopod with convex anterior margin, acute-rounded apex, straight-slightly curved posterior margin, longer than wide. Telson with convex lateral margins and rounded posterolateral corners, posterior margin concave between rounded posterolateral corners.

Remarks. Glypturoides trilobata , the only species, is like species of Neocallichirus but with an exopod on maxilliped 3. In addition, the maxilliped 3 propodus has the free distal margin more oblique than in typical Neocallichirus , and the telson is short with convex lateral margins and concave posterior margin.
