Ceroputo tubulifer ; Tang, 1992 : 392 . Change of combination. Puto tubulifer ; Ben-Dov, 1994 : 431 . Revived combination. We examined two paratypes and another adult female of this Russian species and all possess large dorsal tubular ducts among the cerarii. Similar ducts extend over much of the head and thorax but on the abdomen they are present around the margins only. Tang (1992) transferred this species to Ceroputo but the morphological characteristics fit those of Puto .
