Subgenus Ceraturgus

Both Johnson (1903) and Back (1909) described Ceraturgus as having a densely pubescent third flagellomere. Indeed, both sexes of all species in this subgenus have conspicuous long pubescence densely covering the third flagellomere. This character and the fact that the third flagellomere is as long as or longer than scape and pedicel combined are sufficient to separate the species of this subgenus from those of subgenus Ceraturgopsis .
