Citrogramma fumipenne (Matsumura, 1916):29

Species with entire yellow face, anepisternum yellow and anepimeron black. Similar to Citrogramma luteifrons, from which differs by having metafemur yellow on basal 2/3 and by the different abdominal pattern and geographical distribution.

The species was originally described as Xanthogramma fumipenne by Matsumura. Later, Mengual (2012) moved it to Citrogramma.
