Validation characters

Within Ferrisia-like tubular ducts, dark rim around opening of duct orifice is called sclerotization A, lighter area outside of A is called sclerotization B. Discoidal pores incorporated in or touching A; setae associated with ferrisia-like tubular ducts located in middle of B, not touching A; sclerotization A clearly present and well developed; body elongate oval; without clusters of small oral-collar tubular ducts ventrally on posterior abdominal segments; ventral multiloculars usually restricted to posterior 2 abdominal segments; 1 pair of cerarii.


Ferrisia terani is most similar to F. malvastra (Mc Daniel) by having multilocular pores restricted to vulvar area and without small sized ducts in lateral clusters on posterior abdomen. Ferrisia terani can be distinguished (characters of F. malvastra in parentheses) by having an elongate body (rotund); setae associated with ferrisia-like tubular ducts normally not touching sclerotization A [ where sclerotization A is defined as dark rim surrounding opening of duct orifice], usually in sclerotization B [where sclerotization B is defined as lighter sclerotized area outside of A] (touching A); sclerotization B usually readily apparent (sclerotization B absent or poorly developed). It is difficult to distinguish these species based on morphological characters but the molecular data presented by Kaydan and Gullan (2012) clearly show that they are distinct.

U.S. quarantine notes

Ferrisia was recently revised by Kaydan & Gullan (2012) and at least some of the recent interception records of Ferrisia species represent misidentifications of other species. This species is included because we have examined authentically determined specimens taken in quarantine from Mexico (Lantana, Eriobotrya); and Uruguay (unknown host). The species as currently recognized is found on a number of diverse hosts from Argentina, Guatemala, Mexico and Uruguay. Several species of Ferrisia other than F. dasylirii (Cockerell), F. malvastra McDaniel, F. terani and F. virgata (Cockerell) have been taken at U.S. ports-of-entry including: F. colombiana Kaydan & Gullan (Colombia, cut flower); F. kondoi Kaydan & Gullan (Guyana, Syzygium; Honduras, Codiaeum; Mexico, Echeveria, Gardenia, Zingiber); F. meridionalis (Argentina, grape, grapefruit; Chile, Hypericum; Mexico, Euphorbia; Uruguay, Baccharis); F. pitcairnia Kaydan & Gullan (Puerto Rico, bromeliaceae), F. uzinuri Kaydan & Gullan (Bahamas, Codiaeum; Dominican Republic, Citrus; Haiti, Phaseolus); F. williamsi Kaydan & Gullan (Bolivia, Codiaeum; Brazil, Spondias; Guyana, Codiaeum; Nicaragua, orchid).
