Differential diagnosis

Masona infuscata can be easily distinguished from all the other species of the genus by the following morphological features: (1) scutellum absent (present in M. bulbofemoralis , M. popeye , and M. neon sp. nov.); (2) first flagellomere about 2.5 × as long as medially wide (1.5 or less in M. prognatha and M. neon sp. nov.); (3) antenna longer than head and mesosoma together (shorter in M. prognatha and M. wow sp. nov.); (4) T2–T7 brown (yellow in M. similis ); (5) body length approximately 1.7 mm (0.9–1.2 mm in M. similis ); (6) occipital carina well-developed, almost reaching ventral margin of the gena (short in M. prognatha and M. wow sp. nov.).
