Jumping plant-lice of the New World genus Calinda (Hemiptera: Psylloidea: Triozidae)

Abstract

The genus Calinda is removed from synonymy with Trioza and is redefined based on adult and larval characters. Its 50 constituent species, 36 of which are new, are described and illustrated. Keys are provided for males, females and fifth instar larvae. Lectotypes are designated for 3 species. The taxonomic relationships of 7 morphologically similar Argentine and Chilean species are investigated using morphometric methods. Members of the genus are associated with Baccharis s. 1. (Baccharis s. str., Neomolina and Pingraea), Senecio and Pentacalia spp. (Asteraceae). The larvae are monophagous or narrowly oligophagous and induce galls in the flower heads or on the shoots. The genus is most species-rich in and along the Andes (Ecuador, Peru, Chile).
