Type species. Callianassa tooradin Poore and Griffin, 1979 , by original designation and monotypy.
Diagnosis. Sternite 7 and pereopod 5 coxa-ischium densely setose. Maxilliped 3 ischium and merus more than twice as long as wide at their articulation; ischium with strong proximal lobe on lower margin, wider proximally than distally. Male major cheliped with palm about twice as long as carpus, 1.5 times as long as wide, minor chela half as wide, with short fingers. Minor cheliped fingers with wide gape, without tooth at base of fingers, fingers not closing along length. Male pleopod 1 stout, article 1 setose, article 2 with shallow apical notch; without appendix interna. Male pleopod 2 appendix interna digitiform; appendix masculina not differentiated from endopod apex. Telson widest anteriorly, more or less semicircular.
Remarks. The densely setose sternite 7 and coxa-ischium of pereopod 5 and the stout male pleopod 1 diagnose the only species, P. tooradin Poore and Griffin, 1979 .
Following “examination of the male specimen [of C. tooradin ] preserved in the USNM ”, Sakai (2011) diagnosed Pseudocalliax as a genus of Eucalliacidae possessing a dorsal oval and cardiac sulcus but we found no material in the USNM. We have confirmed by examining types and other specimens ( NMV J301–J303, J59670–J59672) that the species has neither feature, as was confirmed by Sakai earlier (1999a: figs 33a–c). None of his other generic characters is useful. The male pleopod 1 of P. tooradin is not “small and simple” as stated by Sakai (2011) but stout, with article 1 setose and article 2 with shallow apical notch (fig. 19r). The species was inadequately described by Poore and Griffin (1979).
