Male. UNKNOWN.

Etymology. THE SPECIFIC EPITHET IS A PATRONYM HONORING DR. NELSON PAPAVERO FOR HIS GREAT CONTRIbUTIONS IN DIPTERA TAXONOMY AND FOR THE DEVELOPMENT OF BRAZILIAN DIPTEROLOGY.

Geographic Distribution. THIS SPECIES IS KNOWN ONLY FROM THE TYPE LOCALITY, SÃO LUÍS DO PARAITINGA, STATE OF SÃO PAULO, SOUTHERN BRAZIL.

Comments. COLOR INTENSITY OF SCUTUM bROWN MARKS VARIES AS SHOWED IN THE FIGURES 15–16 View FIGURES 12–18 . ONLY ONE SPECIMEN HAS TWO WELL-DEVELOPED OCELLAR TRIANGLE, CONDITION WE CONSIDER A TERATOLOGICAL DEFORMATION.
