Diagnosis

Pterostigma 2.5× as long as wide ( Fig. 27F ); third tergite of metasoma concave medio-apically ( Fig. 27H ); hypopygium with up-curved, medium-sized and wide triangular protuberance ( Fig. 27I ).

Etymology

Named after the nearly quadrate brown patch on the mesoscutum medially, from the Latin ‘ quadrus ’ for ‘four’ and ‘ macula ’ for ‘spot’.
