Caribbean black scale
Probably the same as for S. miranda. "Body oval to round; convex in cross section in older females; body light pink with translucent areas in young females, as specimens mature becoming gray and black; all stages with raised areas forming an "H" on dorsum; with small areas of clear wax on dorsum; without an ovisac; hemispherical body forms a cavity under female where eggs are laid. Occurring on leaves and stems."
Marginal setae broadly fimbriate; anal plates with conspicuous discal seta; discal seta fimbriate; tibio-tarsus not articulated, without sclerosis; ventral submarginal tubular ducts with narrow filament; derm with areolations in older females. Other characters: Dorsal tubular ducts absent; with numerous submarginal dome-shaped tubercles; each anal plate with 3 apical setae and no subdiscal seta; with 3 subapical setae on each plate; anal fold with 6 to 8 fringe setae; ventral tubular ducts restricted to submarginal areas; multilocular pores normally with 10 or more loculi; multiloculars present in vulvar area forward to segment 2; multilocular pores anterior of anterior spiracle predominantly with 5 loculi, about same size as pores laterad of anterior spiracle; claw without denticle; claw digitules equal; 3 pairs of prevulvar setae (posterior pair often obscured by anal plates); stigmatic setae differentiated from other marginal setae, middle seta longer than lateral setae; anal plates with posterior margin about equal to or slightly longer than length of anterior margin; antennae usually 8-segmented; preopercular pores conspicuous, restricted to area anterior of anal plates.
Saissetia neglecta is similar to S. miranda by having a disc seta on anal plates, fimbriate marginal setae, and areolate derm. Saissetia neglecta differs by having tibio-tarsus non-articulated and without sclerosis, and few marginal setae between anterior spiracular furrows (S. miranda has tibio-tarsus articulated and with sclerosis, and more numerous marginal setae between anterior spiracular furrows).
This species was intercepted 126 times on a variety of hosts at U. S. ports-of-entry between 1995 and 2012, with specimens originating from the Azores, Bahamas, Belize, Brazil, The British Virgin Islands, Cayman Islands, China, Colombia, Costa Rica, Cuba, Ecuador, El Salvador, Guatemala, Guyana, Honduras, India, Italy, Jamaica, Malaysia, Mexico, The Netherlands, Nigeria, Puerto Rico, St. Lucia, Taiwan, Thailand, The U.S. Virgin Islands, and Vietnam. We also have examined specimens taken in quarantine from Bahamas (Citrus); Bermuda (Bignonia); Brazil (Citrus), China (Carmona, Litchi); Colombia (Mangifera); Costa Rica (Aralia, Hevea, Musa); Cuba (Annona, Citrus, Gardenia, Heliconia, Persea); Dominican Republic (Annona, Mangifera); El Salvador (Mangifera); Guam (Citrus); Guatemala (Citrus, Gardenia, Stemmadenia); Guyana (unknown host); Haiti (Terminalia); Honduras (Eugenia, Gardenia, Litchi); Hong Kong (Litchi); Jamaica (Annona, Codiaeum, Thunbergia); Martinique (Zingiber); Mexico (Citrus, Couroupita, Dioon, Euphorbia, Gardenia, Mammea, Philodendron, Zingiber); Panama (orchid, Pointsettia); Puerto Rico (Annona, Cajanus, Citrus, Coffea, Mangifera, Psidium); Singapore (Mussaenda), St. Lucia (Citrus); St. Thomas (USVI)(Agave); Samoa (Gardenia); Surinam (Citrus); Taiwan (Serissa); Thailand (Mussaenda, Nephelium); Trinidad (Citrus, Camellia, Thunbergia); Venezuela (Gardenia); The Virgin Islands (Annona). ScaleNet includes hosts on over 30 plant families and distribution records include all zoogeographic regions. No species in the genus Saissetia other than S. coffeae (Walker), S. miranda (Cockerell & Parrott), S. neglecta and S. oleae oleae (Olivier) have been intercepted at U. S. ports-of-entry.
