TYPE MATERIAL ­ Female holotype, 21 female, 13 male paratypes, from Coussapoa microcarpa (Schott) Rizzini (Cecropiaceae), Cananéia, SP (24o 53' 35" S, 47o 50' 14" W), coll. G.J. Moraes, 14 Febr. 2001, on 10 microscopic preparations in the collection of Departamento de Entomologia, Fitopatologia e Zoologia Agrícola, Universidade de São Paulo/ ESALQ, Piracicaba, SP, Brazil. RELATIONSHIP TO HOST ­ undersurface leaf vagrant. ETYMOLOGY ­ The specific designation coussapoae is derived from the generic name of the type host plant.
