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.
