Actually, I had completely forgotten about this prior assessment. In re-reading Townes' color description of the species in which he said the metasomal (abdominal to Townes) terga were laterally white and that the underside of the metasoma was entirely white, it agreed so well with the series of photos by Cotinis, which even included the underside of the metasoma, that I decided it couldn't be anything but this species. Moreover, the fact that three persons have now gotten pics of this species comports well with Townes' statement that the species is moderately common.
