Body nearly triangular; flat to slightly convex in lateral view; body yellow-green in new females, brown in older females; reddish-brown flecks in middle of body; without an obvious wax covering; ovisac absent. Occurring primarily on leaves of host. Males usually absent or rare; eggs laid under the body of female.
Milviscutulus mangiferae is similar to M. ciliatus Williams and Watson by having similarly shaped and positioned anal plates and a triangular body shape. Milviscutulus mangiferae differs by having the apices of the marginal setae strongly frayed (slightly frayed in M. ciliatus) and straight (curved in M. ciliatus). Milviscutulus mangiferae is also similar to Protopulvinaria longivalvata in body shape and the position of the anal plates on the dorsum but differs by lacking distorted coxae (present in P. longivalvata), and shorter anal plates (long in P. longivalvata).
U.S. quarantine notes

S. ports-of-entry between 1995 and 2012, with specimens originating from American Samoa, China, Costa Rica, Ecuador, El Salvador, French Polynesia, Guatemala, Hawaii, Indonesia, Jamaica, Malaysia, Mexico, Nicaragua, Pakistan, The Philippines, Puerto Rico, Singapore, Sri Lanka, Tahiti, The U.S. Virgin Islands, and Vietnam. We also have examined specimens taken in quarantine from Bahamas (Callistemon, Eugenia, Pittosporium); Barbados (Carica, Persea); Colombia (Dieffenbachia); Costa Rica (Artocarpus, Mangifera); Cuba (Mangifera, Musa); Ecuador (Mangifera); El Salvador (Gardenia, Mangifera); Guyana (Mangifera); Honduras (Artocarpus, Gardenia); Indonesia (Mangifera); Israel (Myrtus); Jamaica (Adenium, Artocarpus, Laurus, Mangifera, Rosa); Martinique (Mangifera); Mexico (Bouvardia, Chamaedorea, Citrus, Eugenia, Gardenia, Ixora, Mangifera, Persea, Plumeria, Spathodea, Zingiber); Panama (Colocasia); The Philippines (Lansium, Mangifera, Schefflera); Puerto Rico (Mangifera, Musa); Samoa (unknown host); Singapore (Cordyline); Sri Lanka (Cordyline); St. Croix (Mangifera); St. Thomas (unknown host); Thailand (Cordyline, Ixora); Tobago (Mangifera); Trinidad (Mangifera); Venezuela (Mangifera). ScaleNet includes hosts in over 39 plant families from all zoogeographic regions in 55+ countries. One other species of Milviscutulus other than M. mangiferae has been taken at U. S. ports-of-entry, M. ciliatus Williams & Watson (Tahiti, on Alpinia sp.).
