Diagnosis.

This species is part of the group that has a nearly impunctate second metasomal tergum, including Cl. darlingi , Cl. densepunctatus , Cl. gilbus and Cl. philippinensis . It can be distinguished from these and other species by the combination of the pale antenna, flagellomere I 4 × as long as broad or longer, flagellomere II 1.5 × as long as broad or shorter, flagellomere XI 6.5 × as long as broad, and flagellomeres VII-X asymmetrical. Other diagnostic features include the long malar space, slightly less than 4 midocellar diameters wide, and body with bluish highlights.
