Toxoptera citricida or Toxoptera citricidus? The validity of a specific name (Hemiptera, Aphididae, Aphidini)

The “tropical citrus aphid”, “oriental black citrus aphid” or “brown citrus aphid” —in Spanish: “pulgón café de los cítricos”, in Portuguese: “pulgão preto dos citros”, in French “puceron tropical de l’oranger”— is now a very important pest on Citrus spp. and other species of the family Rutaceae and can live also on other wild and cultivated plants
