Taxonomy of Calophya (Hemiptera: Calophyidae) species associated with Schinus terebinthifolia (Anacardiaceae).

Abstract

Brazilian peppertree, Schinus terebinthifolia Raddi (Anacardaceae), native to Argentina, Brazil, Paraguay, and Uruguay, is one of the most invasive weeds in Florida. In its native range, at least 4 psyllid species of the genus Calophya (Hemiptera: Calophyidae) are associated with it. All 4 species are monophagous and constitute a likely monophyletic group that induce pit galls, usually on the upper leaf surface. Here we revise the taxonomy of these species, 2 of which are described as new, viz. C. lutea sp. nov. and C. praestigiator sp. nov. Morphological differences between the 4 species are detailed and relevant structures are figured. Keys for adults and the fifth instars are provided for the identification of the 8 species known to induce pit galls on Schinus species.
