| Abstract: | The morphology of Cephus fumipennis Eversmann (Hymenoptera: Cephidae) was described.Adults are overall slender, cylindrical, and black, with a metallic luster, covered with grayish brown villi, and 8-11 mm long.The abdomen, legs and forewings bear yellow spots or bands.The larva has a distinct suranal process with its top and lateral surfaces glabrous.C.fumipennis was compared with the other three cephids, C.pygmaeus, C.cinctus, and C.tabidus, and major similarities and differences were given, focusing on body pigmentations, horseshoe shaped depressions and vaginula for adult, and on abdominal tergites VIII, IX and X, and suranal process for larva. |
