NELSON PAPAVERO FOR HIS GREAT CONTRIbUTIONS IN DIPTERA TAXONOMY AND FOR THE DEVELOPMENT OF BRAZILIAN DIPTEROLOGY. <b>Geographic Distribution.</b> THIS SPECIES IS KNOWN ONLY FROM THE TYPE LOCALITY, SÃO LUÍS DO PARAITINGA, STATE OF SÃO PAULO, SOUTHERN BRAZIL. <b>Comments.</b> COLOR INTENSITY OF SCUTUM bROWN MARKS VARIES AS SHOWED IN THE FIGURES 15–16. ONLY ONE SPECIMEN HAS TWO WELL-DEVELOPED OCELLAR TRIANGLE, CONDITION WE CONSIDER A TERATOLOGICAL DEFORMATION.
